This issue's guest speaker.

Tang Yu, Ph.D., Beijing University of Posts and Telecommunications; his research interests are blockchain technology, network security and cryptography. He has participated in several blockchain-related research topics since his research on blockchain technology in 2016, published several patents and academic papers, and has a deep understanding of the underlying blockchain technology.

In the current moment of blockchain industry, various blockchain projects keep appearing. Whether a project has prospects not only lies in its advanced technology and the activity of community operation, but also the strength of its core team is an important indicator to consider, after all, "investment is largely about investing in people".

When it comes to the development of blockchain, there are two people who must be mentioned: Vitalik Buterin, the founder of Ether (known in the community as "V-God"), and Daniel Larimer, the founder of BitShares, Steemit and EOS (known as BM due to his screen name ByteMaster). So, today I'm using a kind of montage to have a virtual conversation ------ excerpting and splicing past remarks and blogs from V-God and BM, using a roundtable conversation format to get to the heart of the blockchain.

Before we launch into the conversation, let's take a look back at the biographies of our two guests and the sparks that have rubbed off on them with blockchain.

Vitalik Buterin, a talented programmer born in 1994 in Moscow, Russia, is the quick-thinking, highly skilled founder of Ether and Bitcoin Magazine. Under his influence, even Russian President Vladimir Putin has become a blockchain fan and met with him to express his support for Ether. Growing up in a family with a strong computer atmosphere, V-God began his programming journey in life at the age of 4. Thanks to his talent for math and programming, the 12-year-old V-God started designing games in C++ when other kids were still playing games. Under the influence of his father, the 17-year-old V-God became aware of Bitcoin and became so interested in the fully distributed digital currency that he began reading various sources and writing blog posts to earn Bitcoin. As V God gradually gained fame within the community, as a co-founder, V God founded Bitcoin Magazine. It was also at this stage that V God gained a deep understanding of the core technology of Bitcoin, and he saw the light of blockchain technology changing the world, but felt that Bitcoin could not take on this responsibility, so V God took a break from his studies eight months after entering university to focus on blockchain, and eventually developed and released Ether. The story that followed is the path of the development of what is known as Ether.

If the term "pride of God" is used to describe the V-God, then "ambitious" is a good description for the BM. The idea of developing a digital currency came to BM before Bitcoin came along, and when he discovered it, he was fully involved in its evangelization and improvement. He had contacted Satoshi Nakamoto in the forum and questioned the slow confirmation of his transactions, but Satoshi Nakamoto responded with an overbearing "If you don't believe me or don't get it, I don't have time to try to convince you, sorry." In 2013, BM's US account in Mt. BM has gained a lot of experience in blockchain development while creating these two blockchain projects, and he found that to achieve an extremely high user experience, then an effective balance between decentralization and efficiency must be sought. So BM went away again to create EOS, working tirelessly to find a free market-based solution.

The technical strengths of V God and BM are undeniable, but looking at the development paths of both, V God seems to be a gifted prodigy immersed in his own world exploring and creating his own ideal country, while BM seems to be a veteran of the battlefield, calmly and calmly using his experience and unique knowledge to realize his vision step by step. To create the experience of a roundtable conversation, here I introduce a live conversation between V God and BM at the North American Bitcoin Conference to open this inter-temporal interview between V God and BM.

(In this conversation, we can see that BM has been concerned about Ether throughput and that PoW will gradually go centralized. )

Moderator: Vitalik and Daniel, as deep players in blockchain projects, how do you guys understand the idea of decentralization?

V-God: The term "decentralization" is often used in the crypto economy, and is even seen as the entirety of blockchain, but the definition of the term is very vague. I believe that "decentralization" can be understood at three levels: first, structural decentralization, a system is composed of multiple physical hosts, and at the same time the system can tolerate some of the physical hosts down; second, policy decentralization, the system should not be ultimately controlled by an organization or an individual to control the entire system, but by all participants in the system to negotiate control; third, logical decentralization, the system's data state and data output is decentralized, from the external view of the system, the decentralized system should be an irregular scattered cluster, if the system is divided into two halves, then each half can be independent of a fully operational system. (from Ref. 1)

Moderator: Vitalik, so how do you think the blockchain system can be explained in terms of these three dimensions?

V-God: the blockchain is structurally decentralized because there is no centralized infrastructure and the entire system is composed of all nodes together; it is also strategically decentralized because no one person has complete control over the entire system; but it is logically centralized because the system has a universally agreed-upon data state at each moment, and because from the outside, the blockchain looks like a single, independent computer system. (from Ref. 1)

Moderator: Daniel, so what do you think about decentralization?

BM: The key to decentralization is really to seek some balance of rights and responsibilities between the individual and the organization. Complete decentralization and centralization is actually hard to measure, as long as it is done in such a way that individuals and organizations are given certain rights and are mutually accountable for making the whole system work well, such decentralization is good decentralization. (from Ref. 2)

Moderator: Daniel, we all know that Bitshares, Steemit and EOS all use the DPoS mechanism, did you consider PoW or other mechanisms at the beginning of the design of these systems?

BM: If you think of a blockchain system as a broadcasting station where anyone can submit and record information, the main questions we face are who can broadcast and who broadcasts when. The PoW mechanism is that it relies on the most powerful broadcast stations being able to broadcast, nodes without broadcast resources have to buy broadcast time from those that do, and those with 51% of the transmitter power can cover 49% of the nodes, which can easily lead to rich people controlling the broadcast stations. Whereas the DPoS mechanism gives each stakeholder the right to vote for the person who controls the station, a majority vote must be obtained to control the station, and this mechanism allows for a separation between controlling the station and having the right to broadcast. (That is, the owner of a super-node can only operate that node, and the use of resources in the node is determined by the person holding the stake. ) So, no one can have a monopoly on controlling radio stations. (from Ref. 3)

Moderator: Daniel, how do you understand the meaning of "consensus" among the many consensus algorithms?

BM: The goal of all consensus algorithms is to determine the order of events. Due to the constraints of space and time, each person observes events in a unique order. Two events generated in the same absolute time will be perceived at two different times, with the time difference depending on the distance of their event sources. This means that all consensus depends on the choice of some person to prove the order of events. These could be the people with the most say, the people with the most equity or the people with the most democratic votes, they could also be a benevolent notary, a committee, or any other group that people can agree on. (from Ref. 3)

Moderator: We all know Daniel has been a proponent of DPoS, a consensus mechanism that can really improve the scalability of blockchain systems tremendously, so Vitalik what are your thoughts on the scalability of blockchain?

V God: The Ethereum community and our key developers have always believed that "scalability" is the most important technical challenge that blockchain systems need to address, and that only with extreme scalability can blockchain systems be made practical at scale. But solving this problem is very difficult, mainly because typical blockchain designs require every node in the network to handle every transaction, which limits the transaction processing capacity of the entire system to the capacity of a single node. As the Ether blockchain reaches 1 million transactions per day, which makes it a regular occurrence for Ether to reach its full transaction capacity, our need for scalability is becoming clearer and more urgent. (from Ref. 4)

MODERATOR: Vitalik, so are there any plans or ideas for improving scalability in Ether now?

V God: we currently propose two ways to improve scalability, one is sharding technology, which involves modifying and updating the protocol at the very bottom of the blockchain, the new protocol retains the decentralized nature and security properties of the blockchain, from the current operation of the blockchain system, it really only requires a small number of nodes to view and process each thing, and then allows multiple things to be processed in parallel at the same time, if you want to learn more about it you can take a look at the Sharding-FAQ on github. (The idea of the sharding technique is to divide all the nodes into multiple node clusters, each of which simultaneously performs block recording and generation in parallel, and then a global higher-level node aggregates the block sharding generated by each node cluster. ) The other is to create a "second layer system", a protocol that does not modify the underlying protocol of the blockchain, but simply puts most of the transactions on the processing chain, which then interacts with the underlying blockchain. We see these two strategies as complementary to each other, and we intend to tackle the scalability of Ether in full force with a two-pronged approach. (from Ref. 4)

Moderator: Daniel, we all know that Bitshares and Steemit have greatly improved the user experience by using the DPoS mechanism, which is certainly an advancement in blockchain technology, but have there been any difficulties in the operation of these two projects?

BM: I'm not going to lie, DPoS does have some problems running, such as voters not being very enthusiastic about voting, many forgetting to change their ballot once they've voted, or them choosing a proxy to vote and then forgetting to follow up, largely because the incentives aren't balanced in the system. And the exchanges also pose some risk, with about 25% of the equity in the Bitshares system being in the hands of a few major exchanges that choose not to vote, which would not help maintain the entire network and would also carry a significant risk of potentially swaying the situation once they were able to vote. (from Ref. 5)

Moderator: Daniel, so what are the improvements in the EOS system to address these situations?

BM:We make voting easier by making voters more aware of candidate nodes through a refined candidate node publishing mechanism, and by simplifying the voting interface for users. We have increased voting participation in Steemit by 20% in the last three years through the measures described above. For exchange concerns, we mitigate this issue primarily by designing exchanges with liquid tokens and constitutional constraints. (from Ref. 6)

Moderator: Daniel, I've heard recently that EOSIO is vulnerable to the "batchOverflow" error, do you have a response to that?

BM: That's a very irresponsible report to begin with, and it's very misleading to those who don't understand the technology. Secondly, "batchOverflow" is not a security vulnerability, but a result of bad programming practices. The smart contract platform cannot prevent developers from making mistakes, and EOS is compiled in C++, which is a very mature compiler with good tools to assist in debugging, so it is easier and safer to compile smart contracts on EOS. (from Ref. 7)

MODERATOR: Vitalik, Daniel's last question, what are your future plans for you guys?

V God: I will focus on the theoretical research of some basic protocols, such as Casper, Plasma, Sharding, etc. (from Ref. 8)

BM: I'm certainly fully prepared for EOS to go live on the main web in June.

Off-topic: by analyzing the blogs and statements of V-God and BM, I found that they are both extreme idealists, and both aspire to find a crypto-economic solution to safeguard people's life, liberty, property and justice. V-God, due to his extreme talent, aspired to find a black box of a crypto economy in which people would be free from their own tragic corruption. BM, because of his own experience of the ups and downs of this world, builds an effective tool to achieve his ideals on the roots of the real world. Many people will define Ether as blockchain 2.0 and EOS as blockchain 3.0, while I think from the design concept of both EOS is more like 2.0 and Ether is 3.0, but the progress of technology has to go forward step by step, and the progress of concept has to be in line with the current status of technology development, so the appropriate compromise on reality is actually for better forward movement.
