Gavin Wood's "Trust" and "Truth"

This article is the speech of Dr. Gavin Wood, the founder of Boca, at the 5th Global Summit on Blockchain. Dr. Gavin Wood first explained his views on "trust" and "truth" and introduced parallel chains, parallel threads, and transfer bridges of Boca. The 5th Blockchain Global Summit was hosted by Wanxiang Blockchain Lab, which was guided by the Shanghai Economic and Information Commission and the Shanghai Hongkou District People's Government. It also received PlatON, Weizhong Bank, Qtum, MYKEY, Nebulas. Irisnet, Blockstack, Harmony, Qiming Ventures and other companies work together to support.

Hello everyone! The theme of my speech was decided after I read the agenda listed on the website of this year's Wanxiang Summit. I saw the theme of all the speakers and saw that Web3.0 was mentioned many times, but everyone also often mentioned To the word "trust", this seems a bit uncoordinated with Web 3.0. The first part of my speech today talks about trust, truth, or truth. The second part will talk about the wave card.

Trust and truth

I think trust is about the same as belief. It refers to the extent to which one person believes another person or another group of people and an organization. In fact, it is a people-oriented concept. For example, I believe that another person who does the job for me, or I trust the bank to manage my funds. In both cases, the objects I trust are actually people or The organization of people. We generally don't say that I trust physics, or I trust that the sun will rise tomorrow, which not only sounds strange, but also unreasonable. why? Because the sun will definitely rise tomorrow, this does not need to be trusted, they are already truth/truth.

Truth is related to human relations. It describes the world and describes the universe. In order to reach a consensus description, we will use the concept of logic and reason to describe, we will appeal to other people's reason, and then convince them. Evidence is a synonym for truth, which is something based on science. Because science is a process-based approach to finding truth and truth, we need to find the truth in a scientific way, use the truth to describe the world, and manipulate the world. In other words, truth (truth) is our manipulation or control. The weapon of this world.

Trust is made up of several people, and with trust we can do a good job. The premise of trust has a hypothesis that the other party will act in good faith, and what he does will benefit us. This is trust. We have trust, although sometimes there is no reason to believe that the other party has a goodwill behavior, but we will blindly believe in things that are in our own interests.

But the truth is different. The truth is that we hold things in our own hands. We analyze and examine the world and use various principles and models. We believe that these models or principles can predict the future direction, and then we use evidence to verify that this is to resort to reason. In this way, we can interact with the world. If there is no verification, unless you are very lucky, it will eventually fail. Trust is to give the goal to others to complete, the truth / truth is to control things in their own hands and do it themselves. So these two concepts are very different ways of achieving goals.

What does encryption economics have to do with this? Encryption economics is mainly economics. It is a series of models, theorems, and frameworks that enable the human world to interact. These are principles that help us create a functioning system that does not need to trust someone or a group of people to act in good faith. Regardless of whether these people have malicious behavior, the mechanism itself can bring us the right knot, help us create, verify, and prove the world, let us reduce the dependence on trust or zero trust. In short, the system is that we no longer need to trust others. This is not to say that we have created a trusted system. Instead, we created a system that works without trust.

When it comes to trusted systems, it's not the same. This means that if someone maliciously acts in the system, the system is likely to fail and fail. In a trusted system, or a system that requires trust, we often don't know who the other person is, or even find their identity, and there is no way to verify others. Sometimes we have no choice but to choose which system to use or which entity to trust, but the reality is that we have to trust a system to get the job done. So whether it is trust or credibility, it is not the same as truth.

Of course, no system is 100% zero trust, and no system is 100% trusted. Most systems we trust exist in a continuum, such as the government. It's important to know what is included in it. If you put something you need to trust in the truth, you are likely to face a lot of risk.

This is my first part of the speech, mainly on the philosophical side. The next lecture will be more pragmatic. I have studied the project of Poca for two to three years. Here is a brief introduction to Poca.


What is a wave card? In fact, it is the network of the network, and ultimately the network of the network. In other words, it can be combined, it is a platform for blockchain innovators, you can use this platform to create new business logic, and integrate it into a system, and will not fall into the network effect. In other words, you can connect your chain to other existing Polkadot facilities while ensuring its security, performance and efficiency. Boca is Turing-complete, and Ethereum is not really Turing-complete in its true sense because it has GAS.

What kind of products does Boca have, what can it bring? We now have three main products: parallel chains, parallel threads, and transfer bridges. Each one can help you insert or connect a blockchain to a wave card, or you can call it a zero-trust highway. In fact, these three products will have different costs, and their characteristics are different. They have three most important characteristics: security, connectivity, and time to block.

The lowest block time for parallel chains is 6 seconds, which is our relay chain. Parallel chains have the highest level of security, and connectivity is very good, and information is spread very quickly between different blockchains. The parallel thread is similar, except that it is paid by volume, so there is no need to pay a large amount of deposit first, and a small fixed deposit is paid. Every time you want to move forward, or faster, you pay an extra fee, which is very similar to a smart contract. The transfer bridge can do its own thing, find its own certifier, and ensure its own security. In fact, it is to ensure connectivity. Boca will not trust the certifier of the transfer bridge, and once the information is relayed, it is irrevocable. So if you want to accept your money like an exchange, first we need to get some confirmation to accept your money, just like a transfer bridge. With the transfer bridge, your block time is relatively free and less time consuming, up to 1 second or 1 second and a half, which is up to you. The adapter bridge ensures a very high level of security and its freedom is also high. You can embed a wave card into another wave card.

Parallel threads are interoperable with parallel chains, have the same API, and the code is the same. The only difference is that the payment is not the same, the parallel chain needs to pay a deposit, and the parallel thread pays by volume. Parallel chains and parallel threads are interchangeable. When you want to transfer, you can buy a slot in the existing parallel chain, or participate in the auction of the new slot, after the lease is over, you can return to the parallel thread and return the cash. Parallel threads can also enter the transfer bridge to get back and forth, so these three products can be replaced with each other.

In the trunk chain, we want to have enough quantity to support 100 parallel chains or independent blockchains, some are lease slots, some are system levels like adapter bridges, others are placed in a parallel In the thread pool. Such different parallel threads have different arrangements, which are particularly similar to the current smart contracts, except that they are calculated by the chain payment, rather than paid by each user, so the user does not need to hold the Token to use parallel threads. . And the parallel chain that failed to renew the lease can continue to be viable, instead of dying as soon as the renewal fails. In short, parallel threads have high security and interoperability, and every development team can participate.

The above is my sharing. I hope that today's speech will help everyone, thank you!
