Scaling Bitcoin Workshops - Transcripts

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

How EpiK Protocol “Saved the Miners” from Filecoin with the E2P Storage Model?

How EpiK Protocol “Saved the Miners” from Filecoin with the E2P Storage Model?

https://preview.redd.it/n5jzxozn27v51.png?width=2222&format=png&auto=webp&s=6cd6bd726582bbe2c595e1e467aeb3fc8aabe36f
On October 20, Eric Yao, Head of EpiK China, and Leo, Co-Founder & CTO of EpiK, visited Deep Chain Online Salon, and discussed “How EpiK saved the miners eliminated by Filecoin by launching E2P storage model”. ‘?” The following is a transcript of the sharing.
Sharing Session
Eric: Hello, everyone, I’m Eric, graduated from School of Information Science, Tsinghua University. My Master’s research was on data storage and big data computing, and I published a number of industry top conference papers.
Since 2013, I have invested in Bitcoin, Ethereum, Ripple, Dogcoin, EOS and other well-known blockchain projects, and have been settling in the chain circle as an early technology-based investor and industry observer with 2 years of blockchain experience. I am also a blockchain community initiator and technology evangelist
Leo: Hi, I’m Leo, I’m the CTO of EpiK. Before I got involved in founding EpiK, I spent 3 to 4 years working on blockchain, public chain, wallets, browsers, decentralized exchanges, task distribution platforms, smart contracts, etc., and I’ve made some great products. EpiK is an answer to the question we’ve been asking for years about how blockchain should be landed, and we hope that EpiK is fortunate enough to be an answer for you as well.
Q & A
Deep Chain Finance:
First of all, let me ask Eric, on October 15, Filecoin’s main website launched, which aroused everyone’s attention, but at the same time, the calls for fork within Filecoin never stopped. The EpiK protocol is one of them. What I want to know is, what kind of project is EpiK Protocol? For what reason did you choose to fork in the first place? What are the differences between the forked project and Filecoin itself?
Eric:
First of all, let me answer the first question, what kind of project is EpiK Protocol.
With the Fourth Industrial Revolution already upon us, comprehensive intelligence is one of the core goals of this stage, and the key to comprehensive intelligence is how to make machines understand what humans know and learn new knowledge based on what they already know. And the knowledge graph scale is a key step towards full intelligence.
In order to solve the many challenges of building large-scale knowledge graphs, the EpiK Protocol was born. EpiK Protocol is a decentralized, hyper-scale knowledge graph that organizes and incentivizes knowledge through decentralized storage technology, decentralized autonomous organizations, and generalized economic models. Members of the global community will expand the horizons of artificial intelligence into a smarter future by organizing all areas of human knowledge into a knowledge map that will be shared and continuously updated for the eternal knowledge vault of humanity
And then, for what reason was the fork chosen in the first place?
EpiK’s project founders are all senior blockchain industry practitioners and have been closely following the industry development and application scenarios, among which decentralized storage is a very fresh application scenario.
However, in the development process of Filecoin, the team found that due to some design mechanisms and historical reasons, the team found that Filecoin had some deviations from the original intention of the project at that time, such as the overly harsh penalty mechanism triggered by the threat to weaken security, and the emergence of the computing power competition leading to the emergence of computing power monopoly by large miners, thus monopolizing the packaging rights, which can be brushed with computing power by uploading useless data themselves.
The emergence of these problems will cause the data environment on Filecoin to get worse and worse, which will lead to the lack of real value of the data in the chain, high data redundancy, and the difficulty of commercializing the project to land.
After paying attention to the above problems, the project owner proposes to introduce multi-party roles and a decentralized collaboration platform DAO to ensure the high value of the data on the chain through a reasonable economic model and incentive mechanism, and store the high-value data: knowledge graph on the blockchain through decentralized storage, so that the lack of value of the data on the chain and the monopoly of large miners’ computing power can be solved to a large extent.
Finally, what differences exist between the forked project and Filecoin itself?
On the basis of the above-mentioned issues, EpiK’s design is very different from Filecoin, first of all, EpiK is more focused in terms of business model, and it faces a different market and track from the cloud storage market where Filecoin is located because decentralized storage has no advantage over professional centralized cloud storage in terms of storage cost and user experience.
EpiK focuses on building a decentralized knowledge graph, which reduces data redundancy and safeguards the value of data in the distributed storage chain while preventing the knowledge graph from being tampered with by a few people, thus making the commercialization of the entire project reasonable and feasible.
From the perspective of ecological construction, EpiK treats miners more friendly and solves the pain point of Filecoin to a large extent, firstly, it changes the storage collateral and commitment collateral of Filecoin to one-time collateral.
Miners participating in EpiK Protocol are only required to pledge 1000 EPK per miner, and only once before mining, not in each sector.
What is the concept of 1000 EPKs, you only need to participate in pre-mining for about 50 days to get this portion of the tokens used for pledging. The EPK pre-mining campaign is currently underway, and it runs from early September to December, with a daily release of 50,000 ERC-20 standard EPKs, and the pre-mining nodes whose applications are approved will divide these tokens according to the mining ratio of the day, and these tokens can be exchanged 1:1 directly after they are launched on the main network. This move will continue to expand the number of miners eligible to participate in EPK mining.
Secondly, EpiK has a more lenient penalty mechanism, which is different from Filecoin’s official consensus, storage and contract penalties, because the protocol can only be uploaded by field experts, which is the “Expert to Person” mode. Every miner needs to be backed up, which means that if one or more miners are offline in the network, it will not have much impact on the network, and the miner who fails to upload the proof of time and space in time due to being offline will only be forfeited by the authorities for the effective computing power of this sector, not forfeiting the pledged coins.
If the miner can re-submit the proof of time and space within 28 days, he will regain the power.
Unlike Filecoin’s 32GB sectors, EpiK’s encapsulated sectors are smaller, only 8M each, which will solve Filecoin’s sector space wastage problem to a great extent, and all miners have the opportunity to complete the fast encapsulation, which is very friendly to miners with small computing power.
The data and quality constraints will also ensure that the effective computing power gap between large and small miners will not be closed.
Finally, unlike Filecoin’s P2P data uploading model, EpiK changes the data uploading and maintenance to E2P uploading, that is, field experts upload and ensure the quality and value of the data on the chain, and at the same time introduce the game relationship between data storage roles and data generation roles through a rational economic model to ensure the stability of the whole system and the continuous high-quality output of the data on the chain.
Deep Chain Finance:
Eric, on the eve of Filecoin’s mainline launch, issues such as Filecoin’s pre-collateral have aroused a lot of controversy among the miners. In your opinion, what kind of impact will Filecoin bring to itself and the whole distributed storage ecosystem after it launches? Do you think that the current confusing FIL prices are reasonable and what should be the normal price of FIL?
Eric:
Filecoin mainnet has launched and many potential problems have been exposed, such as the aforementioned high pre-security problem, the storage resource waste and computing power monopoly caused by unreasonable sector encapsulation, and the harsh penalty mechanism, etc. These problems are quite serious, and will greatly affect the development of Filecoin ecology.
These problems are relatively serious, and will greatly affect the development of Filecoin ecology, here are two examples to illustrate. For example, the problem of big miners computing power monopoly, now after the big miners have monopolized computing power, there will be a very delicate state — — the miners save a file data with ordinary users. There is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. And after the big miners have monopolized computing power, there will be a very delicate state — — the miners will save a file data with ordinary users, there is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. Because I can fake another identity to upload data for myself, but that leads to the fact that for any miner I go to choose which data to save. I have only one goal, and that is to brush my computing power and how fast I can brush my computing power.
There is no difference between saving other people’s data and saving my own data in the matter of computing power. When I save someone else’s data, I don’t know that data. Somewhere in the world, the bandwidth quality between me and him may not be good enough.
The best option is to store my own local data, which makes sense, and that results in no one being able to store data on the chain at all. They only store their own data, because it’s the most economical for them, and the network has essentially no storage utility, no one is providing storage for the masses of retail users.
The harsh penalty mechanism will also severely deplete the miner’s profits, because DDOS attacks are actually a very common attack technique for the attacker, and for a big miner, he can get a very high profit in a short period of time if he attacks other customers, and this thing is a profitable thing for all big miners.
Now as far as the status quo is concerned, the vast majority of miners are actually not very well maintained, so they are not very well protected against these low-DDOS attacks. So the penalty regime is grim for them.
The contradiction between the unreasonable system and the demand will inevitably lead to the evolution of the system in a more reasonable direction, so there will be many forked projects that are more reasonable in terms of mechanism, thus attracting Filecoin miners and a diversion of storage power.
Since each project is in the field of decentralized storage track, the demand for miners is similar or even compatible with each other, so miners will tend to fork the projects with better economic benefits and business scenarios, so as to filter out the projects with real value on the ground.
For the chaotic FIL price, because FIL is also a project that has gone through several years, carrying too many expectations, so it can only be said that the current situation has its own reasons for existence. As for the reasonable price of FIL there is no way to make a prediction because in the long run, it is necessary to consider the commercialization of the project to land and the value of the actual chain of data. In other words, we need to keep observing whether Filecoin will become a game of computing power or a real value carrier.
Deep Chain Finance:
Leo, we just mentioned that the pre-collateral issue of Filecoin caused the dissatisfaction of miners, and after Filecoin launches on the main website, the second round of space race test coins were directly turned into real coins, and the official selling of FIL hit the market phenomenon, so many miners said they were betrayed. What I want to know is, EpiK’s main motto is “save the miners eliminated by Filecoin”, how to deal with the various problems of Filecoin, and how will EpiK achieve “save”?
Leo:
Originally Filecoin’s tacit approval of the computing power makeup behavior was to declare that the official directly chose to abandon the small miners. And this test coin turned real coin also hurt the interests of the loyal big miners in one cut, we do not know why these low-level problems, we can only regret.
EpiK didn’t do it to fork Filecoin, but because EpiK to build a shared knowledge graph ecology, had to integrate decentralized storage in, so the most hardcore Filecoin’s PoRep and PoSt decentralized verification technology was chosen. In order to ensure the quality of knowledge graph data, EpiK only allows community-voted field experts to upload data, so EpiK naturally prevents miners from making up computing power, and there is no reason for the data that has no value to take up such an expensive decentralized storage resource.
With the inability to make up computing power, the difference between big miners and small miners is minimal when the amount of knowledge graph data is small.
We can’t say that we can save the big miners, but we are definitely the optimal choice for the small miners who are currently in the market to be eliminated by Filecoin.
Deep Chain Finance:
Let me ask Eric: According to EpiK protocol, EpiK adopts the E2P model, which allows only experts in the field who are voted to upload their data. This is very different from Filecoin’s P2P model, which allows individuals to upload data as they wish. In your opinion, what are the advantages of the E2P model? If only voted experts can upload data, does that mean that the EpiK protocol is not available to everyone?
Eric:
First, let me explain the advantages of the E2P model over the P2P model.
There are five roles in the DAO ecosystem: miner, coin holder, field expert, bounty hunter and gateway. These five roles allocate the EPKs generated every day when the main network is launched.
The miner owns 75% of the EPKs, the field expert owns 9% of the EPKs, and the voting user shares 1% of the EPKs.
The other 15% of the EPK will fluctuate based on the daily traffic to the network, and the 15% is partly a game between the miner and the field expert.
The first describes the relationship between the two roles.
The first group of field experts are selected by the Foundation, who cover different areas of knowledge (a wide range of knowledge here, including not only serious subjects, but also home, food, travel, etc.) This group of field experts can recommend the next group of field experts, and the recommended experts only need to get 100,000 EPK votes to become field experts.
The field expert’s role is to submit high-quality data to the miner, who is responsible for encapsulating this data into blocks.
Network activity is judged by the amount of EPKs pledged by the entire network for daily traffic (1 EPK = 10 MB/day), with a higher percentage indicating higher data demand, which requires the miner to increase bandwidth quality.
If the data demand decreases, this requires field experts to provide higher quality data. This is similar to a library with more visitors needing more seats, i.e., paying the miner to upgrade the bandwidth.
When there are fewer visitors, more money is needed to buy better quality books to attract visitors, i.e., money for bounty hunters and field experts to generate more quality knowledge graph data. The game between miners and field experts is the most important game in the ecosystem, unlike the game between the authorities and big miners in the Filecoin ecosystem.
The game relationship between data producers and data storers and a more rational economic model will inevitably lead to an E2P model that generates stored on-chain data of much higher quality than the P2P model, and the quality of bandwidth for data access will be better than the P2P model, resulting in greater business value and better landing scenarios.
I will then answer the question of whether this means that the EpiK protocol will not be universally accessible to all.
The E2P model only qualifies the quality of the data generated and stored, not the roles in the ecosystem; on the contrary, with the introduction of the DAO model, the variety of roles introduced in the EpiK ecosystem (which includes the roles of ordinary people) is not limited. (Bounty hunters who can be competent in their tasks) gives roles and possibilities for how everyone can participate in the system in a more logical way.
For example, a miner with computing power can provide storage, a person with a certain domain knowledge can apply to become an expert (this includes history, technology, travel, comics, food, etc.), and a person willing to mark and correct data can become a bounty hunter.
The presence of various efficient support tools from the project owner will lower the barriers to entry for various roles, thus allowing different people to do their part in the system and together contribute to the ongoing generation of a high-quality decentralized knowledge graph.
Deep Chain Finance:
Leo, some time ago, EpiK released a white paper and an economy whitepaper, explaining the EpiK concept from the perspective of technology and economy model respectively. What I would like to ask is, what are the shortcomings of the current distributed storage projects, and how will EpiK protocol be improved?
Leo:
Distributed storage can easily be misunderstood as those of Ali’s OceanDB, but in the field of blockchain, we should focus on decentralized storage first.
There is a big problem with the decentralized storage on the market now, which is “why not eat meat porridge”.
How to understand it? Decentralized storage is cheaper than centralized storage because of its technical principle, and if it is, the centralized storage is too rubbish for comparison.
What incentive does the average user have to spend more money on decentralized storage to store data?
Is it safer?
Existence miners can shut down at any time on decentralized storage by no means save a share of security in Ariadne and Amazon each.
More private?
There’s no difference between encrypted presence on decentralized storage and encrypted presence on Amazon.
Faster?
The 10,000 gigabytes of bandwidth in decentralized storage simply doesn’t compare to the fiber in a centralized server room. This is the root problem of the business model, no one is using it, no one is buying it, so what’s the big vision.
The goal of EpiK is to guide all community participants in the co-construction and sharing of field knowledge graph data, which is the best way for robots to understand human knowledge, and the more knowledge graph data there is, the more knowledge a robot has, the more intelligent it is exponentially, i.e., EpiK uses decentralized storage technology. The value of exponentially growing data is captured with linearly growing hardware costs, and that’s where the buy-in for EPK comes in.
Organized data is worth a lot more than organized hard drives, and there is a demand for EPK when robots have the need for intelligence.
Deep Chain Finance:
Let me ask Leo, how many forked projects does Filecoin have so far, roughly? Do you think there will be more or less waves of fork after the mainnet launches? Have the requirements of the miners at large changed when it comes to participation?
Leo:
We don’t have specific statistics, now that the main network launches, we feel that forking projects will increase, there are so many restricted miners in the market that they need to be organized efficiently.
However, we currently see that most forked projects are simply modifying the parameters of Filecoin’s economy model, which is undesirable, and this level of modification can’t change the status quo of miners making up computing power, and the change to the market is just to make some of the big miners feel more comfortable digging up, which won’t help to promote the decentralized storage ecology to land.
We need more reasonable landing scenarios so that idle mining resources can be turned into effective productivity, pitching a 100x coin instead of committing to one Fomo sentiment after another.
Deep Chain Finance:
How far along is the EpiK Protocol project, Eric? What other big moves are coming in the near future?
Eric:
The development of the EpiK Protocol is divided into 5 major phases.
(a) Phase I testing of the network “Obelisk”.
Phase II Main Network 1.0 “Rosetta”.
Phase III Main Network 2.0 “Hammurabi”.
(a) The Phase IV Enrichment Knowledge Mapping Toolkit.
The fifth stage is to enrich the knowledge graph application ecology.
Currently in the first phase of testing network “Obelisk”, anyone can sign up to participate in the test network pre-mining test to obtain ERC20 EPK tokens, after the mainnet exchange on a one-to-one basis.
We have recently launched ERC20 EPK on Uniswap, you can buy and sell it freely on Uniswap or download our EpiK mobile wallet.
In addition, we will soon launch the EpiK Bounty platform, and welcome all community members to do tasks together to build the EpiK community. At the same time, we are also pushing forward the centralized exchange for token listing.
Users’ Questions
User 1:
Some KOLs said, Filecoin consumed its value in the next few years, so it will plunge, what do you think?
Eric:
First of all, the judgment of the market is to correspond to the cycle, not optimistic about the FIL first judgment to do is not optimistic about the economic model of the project, or not optimistic about the distributed storage track.
First of all, we are very confident in the distributed storage track and will certainly face a process of growth and decline, so as to make a choice for a better project.
Since the existing group of miners and the computing power already produced is fixed, and since EpiK miners and FIL miners are compatible, anytime miners will also make a choice for more promising and economically viable projects.
Filecoin consumes the value of the next few years this time, so it will plunge.
Regarding the market issues, the plunge is not a prediction, in the industry or to keep learning iteration and value judgment. Because up and down market sentiment is one aspect, there will be more very important factors. For example, the big washout in March this year, so it can only be said that it will slow down the development of the FIL community. But prices are indeed unpredictable.
User2:
Actually, in the end, if there are no applications and no one really uploads data, the market value will drop, so what are the landing applications of EpiK?
Leo: The best and most direct application of EpiK’s knowledge graph is the question and answer system, which can be an intelligent legal advisor, an intelligent medical advisor, an intelligent chef, an intelligent tour guide, an intelligent game strategy, and so on.

Vechain in the last 30 Days: Apotheosis, Blockchain X, BMW, University partnership, DApp ecosystem, BitOcean ICO, Carbon banking, Live use cases, Early adopter rewards and more

This post is for those who are new to Cryptocurrency or want to find out more about VeChain. The text "VeChain" has been banned in this subreddit for the last 30 days. For more details about the ban itself, please visit this cryptocurrencymeta post. Changes have been made and official channels of communications have been opened up to prevent this from happening in the future.
All feedback is welcome, and all discussion is encouraged, but please no moon-posting, ridiculous price speculation or baseless FUD. Looking forward to answering any questions you guys have :) VeChain Foundation COO Kevin Feng is holding a Business AMA with Boxmining today, so new information is coming very soon.

TL:DR.

Updates from the last 30 days

It's been a big month for VeChain as they have continued to work and share with the community. Here are the updates from their Official Medium channel and Reddit Rebrand Post

New website - https://www.vechain.org/

It has loads of useful information and a well produced introduction video. I would highly recommend reading through the website to get an idea of the scope of what VeChainThor is trying to accomplish.
"We are controlled by the few, the powerful and the greedy. We should be free. Free to choose, to trade, to create. It is time for a new world, a world founded on safety and security. A world where everything you do creates power, power for all. And you, you will decide the shape of this world. The power to change the future, is in your hands. VeChain." VeChain Introduction Video

What is Blockchain X?

Blockchain X is a global enterprise level public blockchain platform. VeChainThor is referring to their network/protocol as Blockchain X, to differentiate it from Bitcoin (Blockchain 1.0) and Ethereum (Blockchain 2.0 = Blockchain 1.0 + Smart Contracts).

Blockchain X = Blockchain 2.0 + IoT + AI + VET/VeThor = A living digital ecosystem

  • Blockchain = structure - bones, muscle etc (immutable trustworthy network)
  • IoT = senses - touch, vision, taste, smell, sound (collect real world information from RFID/NFC/QR etc.)
  • VET/VeThor = bone marrow/blood - generate blood & circulate (value transfer on the network)
  • AI = brain - information synthesis (automation of network with deep learning)

VeChainThor: the top candidate for enterprise and government level adoption of Blockchain

VeChainThor has an extremely strong development plan geared towards enterprise and government level adoption. If successful in their execution, I see VeChain being the leading cryptoasset comparable to Ethereum in size. The reasons I believe they will succeed are due to their ecosystem development, innovative governance model, robust economic model and strong strategic partnerships. The evidence of their success is snowballing with each new enterprise level partner and client.

DApps & Ecosystem development

The infrastructure layer has adoption in mind at the very core. Governments and enterprises will prioritise safety and security before venturing into blockchain adoption. (Mentioned in the introduction video.) The core DApps, VeVID (Verified identity, KYC/AML), VeVOT (Voting, Governance tool) and VeSCC (Smart Contract Certification, Regulatory compliance) provide the safety and security that governments and enterprises will demand. Blockchain X will have built-in KYC/AML, Governance and Regulation compliance. This sets it apart from other protocols and ICO platforms.

Governance model

The governance model is a balanced mix of decentralisation and centralisation. With problems such as Bitcoin's scaling debate, it appears that a purely decentralised governance structure may be inefficient. VeChain will use a new model of a decentralised system through centralised channels. The final decisions will be made in a decentralised democratic process through VeVOT by stakeholders with voting authority. I believe this model will be more widely adopted as it retains some of the efficient centralised channels that enterprise & government are familiar with, while still giving overall control to the network participants via a democratic voting system.

Economic model

The two-token economic model splits the value in the network into VET and VeThor. VET's primary function is to generate VeThor. VeThor represents the underlying costs of using the VeChainThor blockchain. All smart contract execution and transactions will require payment with VeThor. Through the dynamic rate of VeThor generation, the fiat value of VeThor can be kept relatively stable. For example, if the VeThor price was too high due to an increase in enterprise demand, the VeThor generation rate can be increased, which increases supply, and brings the price back down. The opposite is also true if the VeThor price is too low. The way I see VET is a store of value, a representation of ownership of part of the network and the right to use the network. Whereas VeThor is the perfect medium of exchange and a pure utility token. By using a two-token system, VeThor can have a stable fiat value over a long period of time. A company will be able to calculate how much VeThor will be needed for a consistent fiat value year after year and will be able to budget for this. This is extremely useful for enterprise and government level adoption since it removes the inherent price volatility from a nascent market like crypto.
VeChain also has a Node system, whereby holding VET generates additional rewards. Nodes of different levels will generate up to 200% additional VeThor compared to the base rate. This encourages long term staking in the network and decreases volatility. See the Apotheosis Part II article and X Series Node article for more information. A portion of VET supply will be locked up when nodes activate. Long term VET holders will not sell and downgrade their status. This decreased supply will lead to price increases. Early adopters (Deadline to stake: Before 20th March 2018) will be rewarded in the new X Series Node system. Features include exclusive participation in VeChain ecosystem project whitelists. (Something I'm excited about since I believe there will be a handful of reverse ICOs from traditional enterprise clients)

Technology

VeChain is planning on adding more than 100 additional full-time developers by the end of 2018.
For those interested in the technology of Blockchain X, I would direct you to the Medium AMAs where the VeChain team have provided detailed answers to common questions. Hardware 1, Hardware 2, Software 1 and Software 2 are worth a read.

Strategic partners

The three strategic partners each play a key role in VeChainThor's expansion. PWC has clients which make up 85% of the Fortune 500. DNV-GL is the preferred provider of those Fortune 500 companies for management systems certification services. PWC and DNV-GL will serve to introduce their enterprise clients to VeChain and increase adoption. BitOcean is positioning itself as a Fiat on-ramp for Crypto in Japan through physical ATMs and online exchanges, with approval by Japan's Financial Services Authority. BitOcean also plans to operate in China when regulations are finalised. BitOcean represents a Fiat/VET pairing that may serve to decouple VET/BTC and lead to independence of VET from the whims of BTC price.

Evidence of adoption to date: Existing clients & Investors

VeChain currently has 180 business opportunities in their pipeline for 2018 (compared to 4 use cases in 2016 and 22 in 2017). They have real uses cases and existing clients that range from medium to large enterprises. Revealed clients include Chinese Government Gui'an New Area project, BMW, Groupe Renault, DIG, Kuehne + Nagel, China Unicom, NRCC - State Tobacco, MLILY, Sunshine culture, Hubei Sanxin Cultural Media, Fanghuwang, YIDA future, Madeforgoods and iTaotaoke. Each of these partnerships deserve a detailed post on their own, they are all available on VeChain's Medium page. Taken together, it becomes clear what type of Ecosystem VeChainThor is trying to build.
Jiangsu Printed Electronics and Xiamen Innov Information Technology are technology partners and I suspect will be mass producing the RFID/NFC chips.
Breyer Capital and Fenbushi capital are the two featured investors on VeChain's website. Jim Breyer generally makes some pretty smart investment decisions. His only other crypto investments are Circle and Ethereum.
Bonus news: This week they are presenting with DNV-GL a cold chain supply chain solution at the Global Food Safety Initiative conference 2018. Zoom in and you'll see VeChain Intelligent Control Display System. DNV-GL have also launched their new digital assurance solution, My Story™. Four top Italian wine producers are using My Story™ under supervision of the Italian wine authorities. Twitter and DNVGL link.

China's potential

China is widely known to be anti-cryptocurrency but extremely pro-blockchain. China's "13th Five year plan 2016-2020" focuses on moving up in the value chain by abandoning old heavy industry and building up bases of modern information-intensive infrastructure, with blockchain and Smart Cities being a key technological focus. VeChain has achieved approval from the Government of the People's Republic of China with Gui'an New Area project, multiple mentions on state owned media (CCTV) and deals with state owned enterprises (China Tobacco). China will not fall behind in the international Blockchain race, they will finalise regulations and adopt Blockchain rapidly in the coming years. VeChain appears to be one of the leaders in the field, with their largest office in Shanghai and existing government connections.

Leader in the field

Last but not least, VeChain is leading the field in a number of areas.
  1. Academic research: VeResearch with Michigan State University #1 for supply chain management and another university to be announced
  2. Transparency: quarterly financial reports, regular social media updates, multiple AMAs, response to cryptocurrency ban, directly addressing FUD in official Telegram channels
  3. Corporate responsibility: cryptocurrency disaster recovery plan
  4. Environmental responsibility: Carbon bank initiative with DNV-GL

Skeptics section

In the interests of balanced discussion, I will update this section with skepticism I find in the comments below.
  1. "No whitepaper"
    • VeChain are working on a Whitepaper as part of their Q1 2018 goals. Information normally found in a Whitepaper has been made available through the development plan. I'm actually not too fussed about not having a whitepaper. For me evidence of enterprise adoption is a more useful indicator of how successful VeChainThor could be.
  2. "No official wallet" "No Mainnet"
    • VeChainThor has been operating as a private blockchain since June 2016. Public VeChainThor Blockchain Launch, VeChain Wallet with VeThor Forge Function will be released in Q2 2018 according to the roadmap.
  3. "VeChain are dumping their VET on the open market"
  4. "Can we talk about the fact that the BMW "partnership" is not really a partnership? VEN is allowed to participate into a startup program hosted by BMW. BMW is not a client. http://www.bmwstartupgarage.com/partner " - u/DutchDolt
    • "BMWstartupgarage" has neither been confirmed or denied by BMW or VeChain, it has been spread by a youtuber called "Crypto Gem"
    • Going to the website linked, BMW refers to successful participants as both partners and clients
    • This is still a developing partnership with details under NDA, however the VeChain/BMW link has been confirmed at the VeChain rebranding event and by Sarah VeChain Country Manager
  5. "Vote manipulation" "Shilling" "Brigading" "You're a paid shiller"
    • In the past VeChain Telegram Moderators wilfully participated in brigading, leading to the ban on the word "VeChain" for 30 days in cryptocurrency
    • It is difficult to differentiate manipulated behaviour and organic behaviour on Reddit, the moderators here do an amazing job getting rid of spam and detecting vote manipulation
    • The Official VeChain Foundation has stepped in to help Reddit moderators prevent VeChain vote manipulation
    • Official Telegram Rules: Brigading & Reddit links: We have a new policy regarding Reddit and 'brigading'. No brigading of any kind will be allowed. If you want to post a Reddit link, do so with the "np." prefix added to its URL, for example "np.reddit.com /CryptoCurrency". No spamming for upvotes, as it hurts both of our communities.
    • This is strictly enforced by Telegram moderators and results in a warning then an insta-ban for repeat offenders
    • https://imgur.com/a/sOva9 is being copy-pasted en masse by detractors as evidence of brigading
    • Image shows Boxminig feeling sorry for WTC PR team and a "np" link to a different thread
    • I wish I got paid to shill VeChain, I made this post to share a fundamentally strong crypto with the community _________________________________________________________________________________________

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.
You can find out more about Ethermint here and here

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.

Ethermint

Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.

IBC
IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/twjzlc8hiba31.png?width=1100&format=png&auto=webp&s=2e546142573b61af031e27dac83ddca675a4b693
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

https://preview.redd.it/d4dclm3iiba31.png?width=770&format=png&auto=webp&s=9ca521efc8580800067e1c4e3f74c0ab8df30555
This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344

Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

Sites to Avoid: Definitely DO NOT post these.

Earnsanity — Shady owner, sketchy site. Held giveaway and then refunded the prizes after it was over. History of scamming many others. AVOID AT ALL COSTS UNLESS YOU WANT TO BE SCAMMED.
Paidverts — Shady owner, sketchy site. Keeps doing debt swaps (cash to BAP). Do not post.
Neobux — It isn’t really a scam, but they operate as a pyramid scheme. There’s money to be made online, but it’s definitely not there.
MarketGlory — It does pay out, but the pay is absolutely ridiculous. The only way to make a decent amount of money is to have a lot of referrals, and referral whoring on this subreddit WILL result in a permanent ban.
MindSumo — Not actually a /beermoney site. It’s only spam in this sub.
G2A — Scam/sells stolen keys.
Robinhood — This is spammed on our sub constantly.
Quickthoughts — Many reports of people being banned when trying to withdraw as of 10/2018. Do your due diligence before possibly wasting your time on this app.
Sites with $100+ minimum — These sites usually offer higher than normal payments for simple tasks, with a high minimum to cash out. They are always scams.
Generic news sites that pay you ridiculous amounts to read an article (two euros??) — Common sense should take care of this, but in case it doesn’t, it’s always a scam. The site is usually hosted somewhere in Eastern Europe, and you will never get paid.
Free bitcoin sites/"faucets" (THIS INCLUDES QOINPRO) — This is not referring to those video-viewing/task sites (although they’re still paying fragments of a penny). I’m talking about sites that give you 0.000001BTC to fill a captcha (freebitco.in, dailybitcoins). Admittedly many beermoney sites pay low, but don’t even bother with these.
Also: Bitcoin mining is NO LONGER PROFITABLE. If you're really so keen on getting bitcoins, doing so through an exchange is your best option.
Here are a few more scam sites and sketchy sites.

This is the type of propaganda and manipulation that makes people upset and why many people are angry with the core side of the debate

I keep seeing in r\Bitcoin and even posted here yesterday and on Twitter too, that everyone is saying this one liner trying to paint Roger Ver in a negative light during the WhalePool debate. They keep posting this (emphasis mine):
"I suppose at this point because I feel that the current Core team hasn't listened to me enough"
You can see posts like this here https://www.reddit.com/btc/comments/5iek7f/roger_ver_is_against_segwit_because_the_core_team/
Notice they keep trying to make it seem Roger said "me" me me. It's getting spread all over the place. The fact of the matter is if you listen to the talk online, Roger DOES NOT SAY THIS!
I'm guessing they are getting this from the transcript of the debate that is being floated around by Bitcoin Core developer u/kanzure. It was written by him. You can read the transcript here: http://diyhpl.us/wiki/transcripts/2016-12-14-whalepool/ (archived https://archive.is/2xqMS#selection-353.0-353.49)
These are the main parts in question (I emphasized the parts where kanzure writes "me"):
RV: As I said earlier, I am a bit agnostic on the whole thing. I guess one of my biggest complaints or things that I'm upset about is the censorship that goes on in bitcoin. I'm glad that Whalepool here is giving an opportunity for both sides to be heard. A lot of people in the general bitcoin dabblers or people who are just mildly interested in bitcoin go to reddit and get their news, I think the fact that people getting only one side of the opinion there, I think that's done a big disservice to both sides of my scaling debate. I think a lot of segwit supporters thought that it would have 95% support overnight, and it turned out to not be the case. I think that's a problem for both sides of the issue. One of the things that I would like to see from the Core side and the Core supporters, and I agree that you guys are not theymos and not his mom, but I think people should speak out against theymos and speak out in favor of people posting whatever they want on bitcoin. One of the things that concerns me the most is that I want bitcoin to be a free and open transaction platform where you don't need permission or money to authorize transactions. If people working on bitcoin aren't willing to step up and say bitcoin should operate a certain way, then it makes me hesistant to trust them to maintain bitcoin the way I want them to, without having to get authorization from someone. So if we want to start healing my divide and ending the animosity on both sides, then I think the very very very first step for that would be for people to speak out against theymos on bitcoin and until that happens I'm going to continue to see animosity and the vitriol online. In the early days of bitcoin, it was just one giant lovefest and everyone knew we were going to change the entire world for the better. There's not as much of that lovefest online, and I would like to see that again. I would like to see more people speaking out against theymos on bitcoin moderation. I am agnostic on the segwit question. I don't have enough hashpower to block it. I won't be the lone hold-out if I have 6% at the end.
???: You're an influential voice, Roger. It's here right now. It has undeniable benefits. We can list them. I think that segwit would dramatically benefit at the chance of activation whic hI think is a good idea, it's well tested and it might not be what you want, it's just one step towards more solutions down the road, but your endorsement would go a long way towards convincing miners to start signalling for it. Would you be willing to endorse segwit, and if not, why not?
RV: I'm willing to consider endorsing segwit. I suppose the reason why I'm not going to endorse segwit today is mainly because I feel like the current Core team never listened to my business community using bitcoin.
pgp: that has nothing to do with the code that's there and ready right now. I understand your points about theymos. I think there's moderation in bitcoin. Theymos is not a Core developer. The core devs... you can't say Core didn't listen. There was an ongoing attempt at discussion on the mailing list-- they were working on this problem. It's here now. It doesn't matter how we got here. We have to think about the future. It's a product here, now, it's well tested. It seems to me that it would be a real shame for it to not activate or to delay activation. Why?
RV: I suppose at this point because I feel that the current Core team hasn't listened to me enough. I feel like they didn't listen to the Coinbase, Blockchain.info and the businesses that are bringing bitcoin to the masses. It takes both sides of the equation here, the business side and the technical side to make the protocol robust. I think they pushed out Gavin Andresen who has been treated horribly. I think that's a shame. This is the guy that Satoshi allegedly handed control of the project to. At this point I wouldn't feel bad if additional competing development teams started to rival Core's position.
Listen for yourself what Roger Ver actually says! I updated the transcription from above with the corrections below, where Roger clearly did not say what kanzure wrote. Was this an intentional manipulation or a mistake? I'm not sure, but this is being twisted into something by the trolls from r\Bitcoin!
RV: I'm willing to consider endorsing segwit. I suppose the reason why I'm not going to endorse segwit today is mainly because I feel like the current Core team didn't listen at all to the actual business community using Bitcoin.
RV: I suppose at this point because I feel that the current Core team hasn't listened enough. I feel like they didn't listen to the Coinbase, Blockchain.info and the businesses that are bringing bitcoin to the masses.

For those tuning in, please feel free to ask your questions in the #ama-questions channel on Rocket Chat, which will be active for the duration of the AMA today. Please remember: this is a friendly environment; please be kind and be respectful of our guest and of one another! 🙂
This purpose of these AMAs is to provide a platform for members of the community to ask relevant questions directly to featured guests, and to satisfy any curiosities one may have about our guest’s thoughts, projects, plans and endeavors!
With that, I turn the floor over to our guest. Welcome, Brendan! Maybe you can start by giving a quick update on progress with BAT and Brave!
 
bat-brendaneich Admin 12:59 PM Thanks @bat-jennie.
As people know we're deep into Mercury phase, with a few people working on Gemini (user-private ads, anonymous revenue share to user). We did the first batch of UGP grants last month and will do more in January. We're working on creator referral awards, to pay YouTubers and site owners who bring new users to the platform as measured by 30 days uptime in Brave.
We had a successful pair of bizdev trips to NYC and London over last two months' time, getting close to announcing an ongoing partnership with a top-3 NYC media co.
The tide is turning fast with publishers. Three years ago when I was thinking a lot about brave and studying problems in ad tech, I met with publishers and ad tech people in NYC. Some fear of ad blocking but mostly business as usual, even as programmatic plays launched in previous few years were hitting what now look like peaks (and trying to exit via M&A).
Two years ago I met as Brave founder and pubs were mostly "you're an ad blocker, we hate you" but a few got the larger play. At that point I was thinking about Bravecoin and met with Stephan Tual and co. at Ethereum's London office; helpful but also clear it was too early to do "Bravecoin".
Last year publishers started turning, because their revenue was going down y-o-y, partly from ad blocking but also from G and FB eating the best programmatic ads and owning the user. This year the worm has turned, so to speak -- no one discounts ad blocking and everyone is talking about GDPR + ePrivacy in Europe next year requiring consent for tracking, so with this as background I think we are well-positioned to move into Gemini phase of the BAT roadmap in 1H2018.
 
bat-jennie Admin 1:06 PM Wow, what an update! This is all very exciting news! I’m sure people are just dying to ask you their questions now! Let’s move onto those 🙂.
Our first question comes from Modernity from Rocket Chat:
Why use a separate cryptocurrency (BAT) instead of just using ETH or a more established cryptocurrency?
 
bat-brendaneich Admin 1:08 PM Thanks, @modernity -- the answer is twofold: 1, to raise funds for the project (no shame in that); 2, to precreate the User Growth Pool before the sale to stake users with tokens, gratis. With ETH or other existing cryptocurrencies we would need a rich benefactor to endow the UGP and none were forthcoming. UGP+reserves wallet present notional value is $122M. I don't know of anyone who was willing to give us that much ETH.
When I met with Ethereum folks in July 2015 and talked Bravecoin, I was inspired by "Social Credit" money theory. Give people tokens just for being citizens.
That's the UGP.
 
bat-jennie Admin 1:10 PM @Robert.clark from Rocket Chat asks:
How do you envision the 'moat' of your startup being built? Is it about digging deep into the BAT reward system and creating truly better and more profitable ad experiences for the consumer as well as the advertiser, or more about the privacy focused / decentralized internet browsing experience?
 
bat-brendaneich Admin 1:13 PM Thanks @robert.clark -- we aim to standardize what we can and hope to work with Apple and Mozilla in W3C on anti-tracking specs in new year, so that's not the moat. The moat is attacking Google's main revenue source directly, while using as much chromium code as possible.
That is a durable strategy as Google cannot diversify fast enough, and faces anti-competitive scrutiny in Europe that limits its ability to use MS-like tactics against us. If other browsers want to join in the platform, we will bring them on -- after we have built Gemini phase and specified endpoint as well as on-chain rules.
In this light it is crucial we neutralize Chrome in every area where we do not differentiate by blocking by default. Note: blocking invisible trackers as well as all third party ads (and some 1st party that place with Google DFP), this gives 3-7x speedup on Android vs. Chrome, and Android Chrome has no extensions which means no adblockers.
Google's "ad filter" is cosmetic and doesn't touch trackers or the ads its core business and public stock price depends upon (they'd be bad fiduciaries if they did hurt their revenue materially; I'd join the class action suit!).
My view is G (and FB) are both "stuck"; they have limited ability to disrupt themselves, even ignoring usual big-company and innovator's dilemma problems. When thinking about moats and strategy, I find Mr. Spock's remark that "Military secrets are the most fleeting of all" helpful.
Tech alone isn't a moat. Remember when Steve Jobs was rumored to be considering buying Dropbox? Then a bit later he said "that's just a feature" (meaning OS icloud integration)? The durable strategies go against deep conflicts of interest, in Google's case between Chrome users and G's ad business.
Btw the latest on G's ad filter makes me think they'll get in legal and possibly antitrust trouble, the way they require verification. But we shall see!
 
bat-jennie Admin 1:18 PM @Irak from Rocket Chat asks:
Brave is an obvious buyout target for the major browsers and ad revenue companies. What do you believe would happen to BAT if a buyout occurs?
 
bat-brendaneich Admin 1:21 PM Good q, @irak. I think we won't get bought without proving the Gemini phase at least. If we did get bought, it would be self-destructive to abandon BAT or mess with Brave's terms of use or privacy policy. We're the GDPR or "user privacy by default" option the bigs need. To the extent they cannot move their large-share attention apps toward BAT, they need separate apps.
I can't speculate much more, but I think BAT is safe -- etherscan shows lots of addresses, last I looked, and volume is up. The UGP would be the asset to protect and as we bring on other apps to the BAT ecosystem, we will put it under shared governance.
For Brave and BAT, GDPR looks like the perfect storm along with bad privacy and dopamine-piracy complaints against the big two.
 
bat-jennie Admin 1:22 PM @Coke from Rocket Chat asks:
What are the Brave team's top three priorities at the moment?
 
bat-brendaneich Admin 1:24 PM @Coke, thanks. The BAT ones are 1/ more UGP grants, with sybil attack resistance; 2/ creator referral awards; 3/ publisher onboarding (the top-3 nyc media co. and others). For Brave we have 1/ bug fixes; 2/ performance and memory work; 3/ extension support on laptop/desktop.
 
bat-jennie Admin 1:26 PM @Steve-1 from Rocket Chat asks:
What’s the likelihood of BAT transitioning to its own independent blockchain at some point?
Will BAT switch to an alternative Blockchain due to ETH scaling issues?
 
bat-brendaneich Admin 1:26 PM @steve-1 We have thought about this enough to view it as an option -- no token or coin of value should ever be marooned unless the human element goes wrong. For now we are confident in Ethereum scaling but we're keeping an eye (and will help if we can, as we grow).
 
bat-jennie Admin 1:27 PM @Decisive from Rocket Chat asks:
Is the UGP script locked in any way to prevent a mass sell off, or developepublisher payout via the smart contract, or is it to the discretion of the BAT team?
 
bat-brendaneich Admin 1:28 PM Hi @decisive: Currently locked in a wallet with keys held only by trusted/high-integrity founder-level people.
We don't like fancy smart contracts; I'm skeptical of on-chain governance as right move for upgrading contracts; we're keeping it simple and vetting keyholders who are known and deeply invested in Brave.
Only a few such people; I am one.
 
bat-jennie Admin 1:30 PM A user from Reddit asks:
How is the BAT browser extension planned or being developed?
You have mentioned in the past that he heard Mozilla might be interested in integrating Brave into Firefox. Have there been any updates on that front?
 
bat-brendaneich Admin 1:31 PM First question may be about the idea of a BAT extension for other browsers, but that is premature. The big problem with UGP grants and Gemini-phase ad revenue shares to users is fraud. Just user-funded contributions has a fraud problem too: as with buy widgets, stolen CC identity => $20 charge to buy BAT => contribution at scale via sybils/mturk-users/bots-with-enough-work => settlement to colluding but verified (small blog) publisher. That's why I mentioned sybil-resistance above.
So we can't just make a wish and try monitoring Basic Attention Metrics from an extension, and attributing BAT flows and creating user wallets, from extensions. There can be other problems, which I've noted elsewhere: lack of extension APIs to do all we do for the BAT platform to work (block ads/trackers, HTTPS Everywhere, Fingerprinting Protection, BAM and the ledger), extensions run in JS sandboxes with API limits.
So to put first things first, we will build in Brave while keeping our code as separable from chromium (or the mobile webview on iOS) as possible. After we have those endpoing and on-chain specs I mentioned in pretty good shape, we can assess extension feasibility.
On Mozilla, I can't speak for them. The friend who contacted after the BAT sale signaled interest but said it would take time, to which I said "same here" (per roadmap). I hope that answers the two reddit questions.
 
bat-jennie Admin 1:35 PM @badgamer5000 from Rocket Chat asks:
I've worked in the industry on both the publisher and advertiser side. Conceptually the model is fantastic. Cut out the costly middlemen, better rewards the publisher and the user.
I'm struggling to see how online advertising moves into a permission-based model. Isn't there great risk of a sharp drop in available inventory for both publishers and advertisers?
How do you see this transition period work? Maybe sites use a hybrid during this time?
TLDR - How do you avoid short-term pain for publishers - who are already struggling massively - as they transition to BAT? Especially if Brave market share as a browser increases faster than people think.
 
bat-brendaneich Admin 1:35 PM @badgamer5000 I thought about that for over a year before founding Brave, so good q.
Publishers already face ad blocking cohort of size. E.g. I've heard from CN that Wired and Pitchfork see 30% ad blocker cohort tempting to try to turn around, as Page Fair, Sourcepoint and others wanted to have a go at a couple years ago: 3/7 is ~43% lift if you can convert all those users, but you can't.
Any on tech sites use a strong ad/tracking blocker such as uBO (which we admire and collab with where we can). They don't react well to hostile dialogs to "whitelist, subscribe, or get lost". Every site that tries that loses Alexa share, lol.
So the pitch from us to pubishers is: you lost a large and valuable fraction of your readers -- we can win some back to a paying relationship, pure upside. Make it a positive sum game.
On the ad side, we see such garbage, race to bottom, spray-and-pray deals that we don't worry about getting top brands and agencies doing trials next year; we are warming them up rn. The idea of user-private, low frequency (one a day), long-form/high-CPX video+landing page, personalized ads is strong.
The local machine learning users get when they consent to the BAT ads can see everything: search queries, Amazon queries and consummations, click logs/tab constellations, absolute above the fold and Z-order visibility and viewability. All together we hope this can notice great opportunities for advertiser and user.
E.g. you are shopping for a car, have not quite decided, have tabs open on BMW and Mercedes. You've even set a BMW dealer visit up for 1pm Saturday. Mercedes will pay ~$70 gross for a lead that will take a test drive at their home two hours ahead; 11am Sat we will give the user 70% = $49 in BAT.
This is kind of a best-case and we haven't locked this deal down, so take it as a for-instance. But I'm not worried about getting ad trials, and moving to paying deals as we tune the local machine learning agent.
 
bat-jennie Admin 1:42 PM A user from Reddit asks:
We know that earning BAT isn’t supposed to constitute a full income, but how much money can a user realistically expect to earn per month watching ads?
 
bat-brendaneich Admin 1:45 PM I don't know. If you assumed every user could get a fixed piece of the ~$80B ad spend on digital in US this year, you might see $80B / 250M (people of age to act on ads) x .2 (programmatic share outside G/FB) x .15 = $9.60 per person year. But that is way low for our users, and take it as a lower bound.
Brave's principles are: 1/ consent-based always (user, and publisher if they want to participate); 2/ no tracking data in clear off device to any servers; 3/ revenue share to inventory owner (ad slot owner; "inventory" on "supply side" means ad space) should be 70% (industry standard); 4/ as much or more rev share to user as to Brave, to align interests.
So for user private ads, we will give 70% to user via BAT. If we do programmatic ad slots with pub as partner (recovering some of that revenue lost to ad blocking; positive sum game) we will give pub 70% and 15% to user, 15 to us.
So suppose our users are more valuable than average (early adopters, web and tech and even crypto savvy); take that $320/person-year figure from above ($80B/250Mppl). 70% of 320 is $224. That is a notional upper bound.
My BMW vs. Mercedes lead gen example suggests higher outliers but you don't by a new car every month, lol. Still, attention has not been fairly priced by deep/transparent markets. Let's find out how much users could make. I hope this helps.
 
bat-jennie Admin 1:49 PM @Tyler from Rocket Chat asks:
What was your reaction to the UGP being claimed so quickly?
 
bat-brendaneich Admin 1:49 PM Thanks, @tyler. I expected it to go fast and it suggests both high interest, and growth opportunity -- esp. as we add creator rewards for referring users who stick around 30 days.
 
bat-jennie Admin 1:50 PM A user from Reddit asks:
How does the BAT system differ from Patreon?
 
bat-brendaneich Admin 1:53 PM Great q, anonymous Reddit person! 1/ we are a user agent so work with any verified creator, whether they sign up with another site or not; 2/ we don't censor first parties (whether sites, accounts on YouTube, Twitch, etc.,) as a browser, beyond things like antiphishing/antimalware protection that all browsers use -- if you can verify you own the payable resource (domain name, account) by challenge/response and/or OAuth APIs, you get verified and your fans can support you.
There are still censor risks in (2) at the moment, of course. DNS registrars, account systems, even Brave so we will move toward decentralized and anonymous operation over time -- that is the Apollo phase of the roadmap.
 
bat-jennie Admin 1:54 PM @Jscrypto89 from Rocket Chat asks:
Will there be function to donate/tip creator on the spot instead of waiting for the monthly payment?
 
bat-brendaneich Admin 1:55 PM @jscrypto89 That is timely, as our team thinks the ANONIZE2 protocol we use may support such spot contributions without loss of anonymity.
The other challenge there is blockchain scaling, of course. With Bitcoin in the beta test, and with BAT on Ethereum now, the fees can add up. We're looking at this but the best anonymity and fee amortization is via the 30-days-of-uptime, private-on-device ledger reconciliation => settlement process.
 
bat-jennie Admin 1:56 PM @Frosty from Rocket Chat asks:
What is the most interesting thing you’ve encountered so far, and how has it affected your direction?
 
bat-brendaneich Admin 1:58 PM @frosty i have to say that learning about tokens (from GNT on, as ERC20 was standardized) and realizing I could do "Bravecoin" without having to set up a new blockchain, that was huge (obv. in terms of the token sale but also the UGP).
Another interesting win was ANONIZE, created by CS profs who wanted to anonymize their class surveys. We were looking at randomized response and other techniques in 2015, but ZKP won. We look forward to the evolution of blockchains (zCash already has them; Ethereum hot topic) to absorb this area of research and put it into practice for everyone (ZKP = Zero Knowledge Proof).
 
bat-jennie Admin 2:00 PM @apertus from Rochet Chat asks:
When will BAT be implemented on mobile browsers specifically Android /iOS?
 
bat-brendaneich Admin 2:02 PM Thanks @apertus, and yes: Android ledgeBAT support is hot 1Q2018 initiative and we shall see about iOS. We have good relations with Apple and do not want to have a bad rejected-app day, so stay tuned.
 
bat-jennie Admin 2:02 PM @badger from Rocket Chat asks:
How does the BAT team plan to engage with and foster ease of use for non-technical user audiences?
 
bat-brendaneich Admin 2:04 PM @badger Great question, and we have been a bit short-staffed before 2nd half of this year to answer it well. All new browsers start from what E. von Hippel calls lead users, those who switch browsers fastest and even innovate on web stuff (as web devs, back end pros, power users, etc.). Even for a small-share browser appealing to lead users, we need to smooth out more UX and support more chromium extensions, and we will move fast to do so in 1H2018.
For the non-tech users we aim to keep the defaults right and relieve them from having to learn about crypto. Rn funding the user wallet requires crypto -- but we want to make it easy to use a debit or credit card to do small monthly budget out of goodwill (people do $5-20/month).
With UGP grants and then BAT ads, we really want the more average-at-scale/non-lead user, every user really, to have the option to let their wallet self-fund via UGP up front and then recurring BAT ad revenue and let it drain to their pinned and automatically-designated-by-BAM creators and sites.
That's the steady state we think has simplest user model, no crypto in most users faces unless they want it, etc.
