Does a user always reaches a miner in 1 or 2 hops since Bitcoin network is a small world graph?

Per CSW's talk, miners are connected in a near complete graph, ~1.3 hops away from each other on average. How about a user to a miner? Is it always 1 hop as the video shows? What if a user runs a non-mining full node where he sends his transaction, is it possible for the transaction to go through multiple non-mining nodes before hitting a miner?
Maybe the small world graph only consists of miners when he mentions Bitcoin network?

Is there a website that tracks how many Bitcoin addresses have more than 1 BTC in them?

I have always been curious about this. One of the things I have heard through the years in crypto is 'OMG you need to get 1 Bitcoin, only X million people can have 1 Bitcoin, not even all the worlds millionaires can hold 1 Bitcoin at any one time! Owning 1 Bitcoin puts you in the top 1% of a new financial system...!' etc
But sometimes I feel there is a Fermi Paradox, where if only a very small percentage of the world can hold 1 Bitcoin, "where are" all the people that want to hold 1 Bitcoin? How quickly is the number of addresses that hold 1 Bitcoin going up? Extrapolating, how old will I be when the 'demand for 1 Bitcoin' exceeds the available supply in the network? Dead?
I am looking for a website that can show me this type of graph, so we can all see how the number of addresses has gone up and down over the years that contain over 1 Bitcoin, and track that into the future. I find it to be interesting to think about and would like to see.
I understand the concept of 'holding 1 Bitcoin' is arbitrary, and you can of course hold less than 1. But it cannot be argued that 'OMG just hold 1 Bitcoin' has been a strong message of a lot of people in the space since I can remember. Hence the curiosity.
For the record, I recently saw a video that said the current number of addresses with at least one Bitcoin is at approximately 800,000. It gives me no accurate idea of time or rate of change though.

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.
https://preview.redd.it/jp4oghyhv9q51.png?width=1762&format=png&auto=webp&s=12a1e76f76f902ed328886283050e416db3838a5
The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

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

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.

CashFusion is awesome, and I want it to become the best piece of crypto development, fungibility is critical. Bitcoin was missing it for so long. This tech has potential to make more equivalent $ private and for more people than Monero ever could through higher value and network effect, and fungible bitcoins will make world economically free much faster
So I've some questions for its future, please tell if I'm misinterpreting or missing anything:
  1. The interface: are there plans in EC to replace bottom-right icon with full tab in the wallet with all the settings and, hopefully, graph of your activity with fused coins? Will EC add option to consolidate->fan-out->consolidate... in perpetuity without manual switch? What is the status of adding CashFusion to Bitcoin.com wallet (and making it open source again)? Does Crescent Cash plan to add CashFusion? Any other wallets?
  2. The cost: do people in EC or anyone prominent interested in CashFusion push for 1 sat per tx or subsat fees to make fungibility as affordable as regular 1-to-2 tx? What is BCHN's position in regards to it, no mention in the roadmap https://www.reddit.com/btc/comments/i4rtd2/what_is_bchns_roadmap_is_it_the_same_as/g0kewtg/? Right now and with BCH appreciation in mind especially?
  3. The security: will EC form recommendations itself or with another audit at the number of fusions to achieve some specific goal/level (maybe everyday txs, exchange-level clean, multi-year deposit etc) and add to the software to set it up? Something like "these X coins are fusing; these Y coins were fused Z times which equals this level of security, Link: EC recommendations", with manual override ofc. This could also improve the cost as for now the safest assumption is perpetual fusion. Such recommendations also should take into account liquidity needs of the whole, which makes it complicated
Edit: addtion to 2nd point - would be nice to see ability to set fees manually if it won't affect liquidity pools to much. For some coins (if not for absolute majority) fusing longer, but cheaper is preferable to fusing fast, but more expensive

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Streamr Network: Performance and Scalability Whitepaper


https://preview.redd.it/bstqyn43x4j51.png?width=2600&format=png&auto=webp&s=81683ca6303ab84ab898c096345464111d674ee5
The Corea milestone of the Streamr Network went live in late 2019. Since then a few people in the team have been working on an academic whitepaper to describe its design principles, position it with respect to prior art, and prove certain properties it has. The paper is now ready, and it has been submitted to the IEEE Access journal for peer review. It is also now published on the new Papers section on the project website. In this blog, I’ll introduce the paper and explain its key results. All the figures presented in this post are from the paper.
The reasons for doing this research and writing this paper were simple: many prospective users of the Network, especially more serious ones such as enterprises, ask questions like ‘how does it scale?’, ‘why does it scale?’, ‘what is the latency in the network?’, and ‘how much bandwidth is consumed?’. While some answers could be provided before, the Network in its currently deployed form is still small-scale and can’t really show a track record of scalability for example, so there was clearly a need to produce some in-depth material about the structure of the Network and its performance at large, global scale. The paper answers these questions.
Another reason is that decentralized peer-to-peer networks have experienced a new renaissance due to the rise in blockchain networks. Peer-to-peer pub/sub networks were a hot research topic in the early 2000s, but not many real-world implementations were ever created. Today, most blockchain networks use methods from that era under the hood to disseminate block headers, transactions, and other events important for them to function. Other megatrends like IoT and social media are also creating demand for new kinds of scalable message transport layers.

The latency vs. bandwidth tradeoff

The current Streamr Network uses regular random graphs as stream topologies. ‘Regular’ here means that nodes connect to a fixed number of other nodes that publish or subscribe to the same stream, and ‘random’ means that those nodes are selected randomly.
Random connections can of course mean that absurd routes get formed occasionally, for example a data point might travel from Germany to France via the US. But random graphs have been studied extensively in the academic literature, and their properties are not nearly as bad as the above example sounds — such graphs are actually quite good! Data always takes multiple routes in the network, and only the fastest route counts. The less-than-optimal routes are there for redundancy, and redundancy is good, because it improves security and churn tolerance.
There is an important parameter called node degree, which is the fixed number of nodes to which each node in a topology connects. A higher node degree means more duplication and thus more bandwidth consumption for each node, but it also means that fast routes are more likely to form. It’s a tradeoff; better latency can be traded for worse bandwidth consumption. In the following section, we’ll go deeper into analyzing this relationship.

Network diameter scales logarithmically

One useful metric to estimate the behavior of latency is the network diameter, which is the number of hops on the shortest path between the most distant pair of nodes in the network (i.e. the “longest shortest path”. The below plot shows how the network diameter behaves depending on node degree and number of nodes.

Network diameter
We can see that the network diameter increases logarithmically (very slowly), and a higher node degree ‘flattens the curve’. This is a property of random regular graphs, and this is very good — growing from 10,000 nodes to 100,000 nodes only increases the diameter by a few hops! To analyse the effect of the node degree further, we can plot the maximum network diameter using various node degrees:
Network diameter in network of 100 000 nodes
We can see that there are diminishing returns for increasing the node degree. On the other hand, the penalty (number of duplicates, i.e. bandwidth consumption), increases linearly with node degree:

Number of duplicates received by the non-publisher nodes
In the Streamr Network, each stream forms its own separate overlay network and can even have a custom node degree. This allows the owner of the stream to configure their preferred latency/bandwidth balance (imagine such a slider control in the Streamr Core UI). However, finding a good default value is important. From this analysis, we can conclude that:
  • The logarithmic behavior of network diameter leads us to hope that latency might behave logarithmically too, but since the number of hops is not the same as latency (in milliseconds), the scalability needs to be confirmed in the real world (see next section).
  • A node degree of 4 yields good latency/bandwidth balance, and we have selected this as the default value in the Streamr Network. This value is also used in all the real-world experiments described in the next section.
It’s worth noting that in such a network, the bandwidth requirement for publishers is determined by the node degree and not the number of subscribers. With a node degree 4 and a million subscribers, the publisher only uploads 4 copies of a data point, and the million subscribing nodes share the work of distributing the message among themselves. In contrast, a centralized data broker would need to push out a million copies.

Latency scales logarithmically

To see if actual latency scales logarithmically in real-world conditions, we ran large numbers of nodes in 16 different Amazon AWS data centers around the world. We ran experiments with network sizes between 32 to 2048 nodes. Each node published messages to the network, and we measured how long it took for the other nodes to get the message. The experiment was repeated 10 times for each network size.
The below image displays one of the key results of the paper. It shows a CDF (cumulative distribution function) of the measured latencies across all experiments. The y-axis runs from 0 to 1, i.e. 0% to 100%.
CDF of message propagation delay
From this graph we can easily read things like: in a 32 nodes network (blue line), 50% of message deliveries happened within 150 ms globally, and all messages were delivered in around 250 ms. In the largest network of 2048 nodes (pink line), 99% of deliveries happened within 362 ms globally.
To put these results in context, PubNub, a centralized message brokering service, promises to deliver messages within 250 ms — and that’s a centralized service! Decentralization comes with unquestionable benefits (no vendor lock-in, no trust required, network effects, etc.), but if such protocols are inferior in terms of performance or cost, they won’t get adopted. It’s pretty safe to say that the Streamr Network is on par with centralized services even when it comes to latency, which is usually the Achilles’ heel of P2P networks (think of how slow blockchains are!). And the Network will only get better with time.
Then we tackled the big question: does the latency behave logarithmically?
Mean message propagation delay in Amazon experiments
Above, the thick line is the average latency for each network size. From the graph, we can see that the latency grows logarithmically as the network size increases, which means excellent scalability.
The shaded area shows the difference between the best and worst average latencies in each repeat. Here we can see the element of chance at play; due to the randomness in which nodes become neighbours, some topologies are faster than others. Given enough repeats, some near-optimal topologies can be found. The difference between average topologies and the best topologies gives us a glimpse of how much room for optimisation there is, i.e. with a smarter-than-random topology construction, how much improvement is possible (while still staying in the realm of regular graphs)? Out of the observed topologies, the difference between the average and the best observed topology is between 5–13%, so not that much. Other subclasses of graphs, such as irregular graphs, trees, and so on, can of course unlock more room for improvement, but they are different beasts and come with their own disadvantages too.
It’s also worth asking: how much worse is the measured latency compared to the fastest possible latency, i.e. that of a direct connection? While having direct connections between a publisher and subscribers is definitely not scalable, secure, or often even feasible due to firewalls, NATs and such, it’s still worth asking what the latency penalty of peer-to-peer is.

Relative delay penalty in Amazon experiments
As you can see, this plot has the same shape as the previous one, but the y-axis is different. Here, we are showing the relative delay penalty (RDP). It’s the latency in the peer-to-peer network (shown in the previous plot), divided by the latency of a direct connection measured with the ping tool. So a direct connection equals an RDP value of 1, and the measured RDP in the peer-to-peer network is roughly between 2 and 3 in the observed topologies. It increases logarithmically with network size, just like absolute latency.
Again, given that latency is the Achilles’ heel of decentralized systems, that’s not bad at all. It shows that such a network delivers acceptable performance for the vast majority of use cases, only excluding the most latency-sensitive ones, such as online gaming or arbitrage trading. For most other use cases, it doesn’t matter whether it takes 25 or 75 milliseconds to deliver a data point.

Latency is predictable

It’s useful for a messaging system to have consistent and predictable latency. Imagine for example a smart traffic system, where cars can alert each other about dangers on the road. It would be pretty bad if, even minutes after publishing it, some cars still haven’t received the warning. However, such delays easily occur in peer-to-peer networks. Everyone in the crypto space has seen first-hand how plenty of Bitcoin or Ethereum nodes lag even minutes behind the latest chain state.
So we wanted to see whether it would be possible to estimate the latencies in the peer-to-peer network if the topology and the latencies between connected pairs of nodes are known. We applied Dijkstra’s algorithm to compute estimates for average latencies from the input topology data, and compared the estimates to the actual measured average latencies:
Mean message propagation delay in Amazon experiments
We can see that, at least in these experiments, the estimates seemed to provide a lower bound for the actual values, and the average estimation error was 3.5%. The measured value is higher than the estimated one because the estimation only considers network delays, while in reality there is also a little bit of a processing delay at each node.

Conclusion

The research has shown that the Streamr Network can be expected to deliver messages in roughly 150–350 milliseconds worldwide, even at a large scale with thousands of nodes subscribing to a stream. This is on par with centralized message brokers today, showing that the decentralized and peer-to-peer approach is a viable alternative for all but the most latency-sensitive applications.
It’s thrilling to think that by accepting a latency only 2–3 times longer than the latency of an unscalable and insecure direct connecion, applications can interconnect over an open fabric with global scalability, no single point of failure, no vendor lock-in, and no need to trust anyone — all that becomes available out of the box.
In the real-time data space, there are plenty of other aspects to explore, which we didn’t cover in this paper. For example, we did not measure throughput characteristics of network topologies. Different streams are independent, so clearly there’s scalability in the number of streams, and heavy streams can be partitioned, allowing each stream to scale too. Throughput is mainly limited, therefore, by the hardware and network connection used by the network nodes involved in a topology. Measuring the maximum throughput would basically be measuring the hardware as well as the performance of our implemented code. While interesting, this is not a high priority research target at this point in time. And thanks to the redundancy in the network, individual slow nodes do not slow down the whole topology; the data will arrive via faster nodes instead.
Also out of scope for this paper is analysing the costs of running such a network, including the OPEX for publishers and node operators. This is a topic of ongoing research, which we’re currently doing as part of designing the token incentive mechanisms of the Streamr Network, due to be implemented in a later milestone.
I hope that this blog has provided some insight into the fascinating results the team uncovered during this research. For a more in-depth look at the context of this work, and more detail about the research, we invite you to read the full paper.

Blockchain is the Future of Supply Chain Internet of Things.

Blockchain is the Future of Supply Chain Internet of Things.
https://preview.redd.it/g5xbk5mgnvk51.jpg?width=2400&format=pjpg&auto=webp&s=85009067bb61a46bc20a6a5963e128d35e7e6e56
The wave of change that Blockchain has spurred across different sectors is known to everyone. Technologies run on data, and a large volume of data is amassed every day. With much of information lying astray in the virtual world, there is always a probability of being hacked or altered. It is one of the reasons that companies are now exploring alternatives that can not only enhance the performance of the system but, at the same time, proved transparency and data security. The notion of fair trade, transparency, and sustainability is becoming paramount for customers, and it impacts their buying decisions.
Well, Blockchain is the panacea that most of the companies are now eyeing at. This decentralized technology started its journey as the underlying technology for Bitcoin exchange. Still, later on, it expanded its horizon, and now it finds a multitude of uses across different sectors. This technology has defenestrated the need to rely on conventional vulnerable digital platforms. Rather Blockchain provides a decentralized podium wherein peer-to-peer networking works.
Blockchain and IoT in Supply Chain
Blockchain is omnipresent. You name the technology, and Blockchain will have its use case there. Here our focus in on the IoT and supply chain. Both these are a pillar for modern-day business functioning. At the same time, connected devices ensure seamless integration. We are living in the era of connected devices, and this reliance is increasing. The supply chain forms the pillar of every organization, and its seamless functioning is paramount for increasing the business’s productivity.
Some of the problems associated with the conventional supply chain system are that it lacks transparency, tracking of information, and prominence of red-tapism. With all these issues into the picture, the supply chain system fails to work at its best potential. But, with the intervention of Blockchain technology, we can expect the system to become more productive and transparent.
Blockchain’s key features like provenance, transparency, decentralization, data security, and no third-party interference. With all these features, the Blockchain platform becomes a key help when it comes to removing the bottlenecks of conventional platforms. There is a lot of data about companies in the virtual world; when we merge all this data with Blockchain, it gets encrypted cryptographically, thus providing data security.
Another area where Blockchain and IoT can work is when it comes to paperwork. Transportation of a container from one place to another. If we take this example in a conventional platform, then there would be many intermediaries. Still, when it comes to Blockchain and IoT, then all the process gets automated and digitalized along with the security of information. This is eventually going to increase the productivity of the business.
Conclusion- From the above discussion, you can decipher that presence of advanced technologies like Blockchain and IoT is going to boost the supply chain system, and thus helping the business grow by gaining the trust of customers. Thus, it will lead to a demand for professionals who can leverage the best of both these technologies, and if you wish to make a career in this domain, then there is no better time than starting today. Enroll for Blockchain training or online Blockchain certification program by Blockchain Council to make your career graph grow.

RiB Newsletter #14 – Are We Smart (Contract) Yet?

We’re seeing a bunch of interesting Rust blockchain and crypto projects, so this month the “Interesting Things” section is loaded up with news, papers, and project links.
This month, Elrond, appeared on our radar with the launch of their mainnet. Although not written in Rust, it runs Rust smart contracts on its Arwen WASM VM, which itself is based on the Rust Wasmer VM. Along with NEAR, Nervos, and Enigma (and probably others), this continues an encouraging trend of blockchains enabling smart contracts in Rust. See the “Interesting Things” section for examples of Elrond’s Rust contracts.
Rust continues to be popular for research into zero-knowledge proofs, with Microsoft releasing Spartan, a zk-SNARK system without trusted setup.
In RiB news, we published a late one-year anniversary blog post. It has some reflection on the changes to, and growth of, RiB over the last year.
The Awesome Blockchain Rust project, which is maintained by Sun under the rust-in-blockchain GitHub org, has received a stream of updates recently, and is now published as the Awesome-RiB page on rustinblockchain.org.
It’s a pretty good resource for finding blockchain-related Rust projects, with links to many of the more prominent and mature projects noted in the RiB newsletter. It could use more eyes on it though.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
ethers.rs
ethers.rs is an Ethereum & Celo library and wallet implementation, implemented as a port of the ethers.js library to Rust.
Ethereum client programming is usually done in JavaScript with either web3.js or ethers.js, with ethers.js being the newer of the two. These clients communicate to an Ethereum node, typically via JSON-RPC (or, when in the browser, via an “injected” client provider that follows EIP-1193, like MetaMask).
ethers.rs then provides a strongly-typed alternative for writing software that interacts with the Ethereum network.
As of now it is only suited for non-browser use cases, but if you prefer hacking in Rust to JavaScript, as some of us surely do, it is worth looking into for your next Ethereum project.
The author of ethers.rs, Georgios Konstantopoulos, accepts donations to sponsor their work.
Note that there is also a Rust alternative to web3.js, rust-web3.
