比特大陆姜家志：我重仓了BCH！

姜家志，比特大陆技术负责人，BCH社区资深开发者、哥白尼项目核心开发者。2013年起接触比特币，曾经开发过比太钱包。他一直从事区块链底层协议的开发工作，对区块链行业有着深入的理解。

即使是深耕于区块链行业的姜家志，他也谦逊地说，自己不是最懂比特币的人。他说，如果整个公链的发展有10000步，那么现在可以说才走了几步而已，可能连10步都没走到。

Even Kang Jiachi, who was deep in the block chain industry, was humbled to say that he was not the one who knew best bitcoin. He said that if the whole public chain developed 10,000 steps, it could be said that only a few steps had been taken now, and maybe 10 steps had not been reached.

币圈一天，人间一年。姜家志很强调团队快速学习的能力，以及项目的技术应当不断地更新与迭代。本周五晚，哔哔邀请姜家志先生来到直播间，以下为文字整理。

KANG Jia Chi emphasizes the ability of the team to learn quickly, and the technology of the project should be constantly updated and updated.

曾经不敢提“比特币”三个字

never dared to mention "bitcoin"

我从2013年开始接触比特币，曾经参与过比太钱包的开发，现在是比特大陆技术负责人，见证了BCH从分裂发展到现在的过程。我现在是哥白尼项目的核心开发者，主要通过Go语言实现BCH客户端。

I've been in contact with Bitcoin since 2013, and I've been involved in the development of the Beether Wallet, and I'm now the technical director of the Bit continent, witnessing the evolution of the BCH from division to the present. I'm now the core developer of the Copernicus project, primarily the BCH clientele through the Go language.

从2013年到现在，变化最大的是人们对于比特币的态度，从完全鄙视到比较认可。

From 2013 to the present, the most significant change has been in the attitude towards Bitcoin, from total stigmatization to comparative recognition.

以前，我坐公交车，如果提到“比特币”三个字，说话声音就会变小。我和家人吃饭也不能提到比特币，因为大家都会用异样的眼神看你，感觉你掉入了传销的深渊。

Before, I took the bus, and if I mentioned the word "bitcoin," my voice would be smaller. Me and my family at dinner couldn't talk about bitcoin, because everyone would look at you with different eyes and feel like you've fallen into the abyss of distribution.

直到经历了2017年大牛市，大家对比特币、区块链才有了更深的了解。大家开始认可我的工作，我也能正常地讨论比特币和区块链。

It was only after the Big Bulls in 2017 that you got a deeper understanding of the bitcoin and block chains. You started to recognize my work, and I was able to discuss the bitcoins and block chains properly.

我早期是奥地利学派的支持者，在看了比特币的白皮书和源码之后，我深深认可比特币的思想。简单来说，比特币是唯一一个人类使用数学的方式来保护自己财富的东西。我们支持比特币，也是因为比特币能够让更多的人远离通货膨胀。

I was an early supporter of the Austrian school, and after reading Bitcoin's white paper and source code, I deeply endorsed Bitcoin's idea. Simply put, Bitcoin is the only thing that humans use mathematically to protect their wealth. We support Bitcoin, also because Bitcoin can keep more people away from inflation.

三位区块链大神

Three block chains

中本聪很伟大，他在我心目中的地位类似于牛顿、爱因斯坦。他让人类能够真正实现财务上的自由，中本聪甚至能够超越爱因斯坦等跨世纪人物。

He's great, and he's like Newton and Einstein to me. He's allowed human beings to truly be financially free, and he's able to outperform even generations like Einstein.

Vitalik，他在中本聪的基础上实现了智能合约，这对整个行业的发展意义巨大。中本聪解放了人类对于货币的认知，而Vitalik解放了人类对于融资、股票的认知。中本聪释放了货币市场，Vitalik释放了风险投资市场。

Vitalik, who has achieved a smart contract on the basis of his middle brain, has great significance for the development of the whole industry. Bentalik freed humans' knowledge of money, while Vitalik freed humans' understanding of finance and stocks. He freed the money market, and Vitalik released the venture capital market.

BM是一个技术天才，他在早期和中本聪有过很多的沟通，对于区块链的理解也非常深入。BM是一个比较简朴的人，他对物质上的追求不高。但BM也是一个比较有争议的人，他放弃了早期的项目，并从社区退出。EOS是他的第三个项目，他在EOS上投入了很大的精力，EOS代码整体质量比较高，但是最终能否成功，有待大家一起去看。

BM is a technical genius, he had a lot of early and mid-brain communication and a lot of understanding of the block chain. BM is a relatively simple person, he's not very ambitious in material terms. But BM is also a more controversial person, and he abandons early projects and withdraws from the community. EOS is his third project, and he has devoted a lot of energy to EOS, and the overall quality of EOS code is high, but ultimately it's going to work.

我重仓了BCH

{\bord0\shad0\alphaH3D}I'm back in business with BCH {\bord0\shad0\alphaH3D}

BTC是依靠自己的网络效应一直处于市值第一。

BTC has always been at the top of the market market by relying on its own network effects.

ETH最具创新能力，基本上所有埃西欧项目都在以太坊上发展。未来，如果以太坊能够解决TPS的问题，每秒TPS能达到200甚至2000，那么这条公链将迎来爆炸式的发展。

The ETH is the most innovative, and basically all the projects in E.C.E. are going to be developed in E.T. If in the future E.T.P.S. can solve T.S. problems, it can reach 200 or 2,000 per second, the public chain will be explosive.

BCH的设计承载了中本聪早期的设想。BCH的优点是TPS能够达到很高的水平，但缺点也很明显，使用BCH的人还比较少。

The design of the BCH carries the idea of an early medium-class brain. The advantage of BCH is that the TPS can reach a very high level, but the disadvantages are also obvious, and the number of people using the BCH is relatively low.

EOS已经形成了一定的社区模型，但是因为它遇到的问题还比较少，所以还需要一定的时间去发展。

EOS has developed a community model, but because of its relatively few problems, it will take some time to develop.

ADA是一个比较有意思的币。它的算法经过严格的数学证明，而且ADA真正实现了在上面开发新链。但是它的数学证明有一定的问题，它的前提假设过强，如果这些假设没有达到它所要求的程度，证明就会出现问题。至于ADA未来上线还会遇到哪些问题，有待观察。

The ADA is a more interesting currency. The algorithm of

我重仓了BCH，还有少量的以太坊。BCH是我早期认可的比特币，作为货币来讲，BCH能够承担这个使命。如果BCH能够解决创新性的问题，未来将会迎来一个很大的爆发期。

I'm back in business with the BCH, and there's a small amount of Ether. The BCH is the bitcoin I recognized earlier, and in monetary terms, the BCH can take on this mission. If the BCH solves the problem of innovation, it's going to have a big eruption in the future.

义无反顾支持大区块

BTC和BCH选了两种不同方式进行扩容。BTC通过部署闪电网络，BCH采用了链上大区块扩容方式。目前大区块是最简单的实现扩容效果的方式。

BTC and BCH have chosen two different ways to expand their reach. By deploying the lightning network, BTC has adopted the large blocks of the chain. The larger blocks are currently the simplest way to achieve the expansion effect.

经历了2017年的大牛市，比特币的拥堵问题就成了一个很大的问题，我当时和很多支持小区块的人进行过沟通。沟通之后，我义无反顾地支持了大区块。

After the big cattle market in 2017, the problem of the crowding of Bitcoin became a big problem, and I was in communication with a lot of supporters of the block. After that, I backed the block.

小区块的思想不符合当时我所理解的比特币，我所理解的比特币是能够跨境支付，低手续费以及快速确认，这才是它的优势。因为拥堵导致当时比特币每笔手续费达到1000元，如果是这样，大家没人会用。

The idea of the block is not in line with what I understood at that time as bitcoin, which I understood to be the ability to pay across borders, low fees and quick confirmation, which is its advantage. , because of congestion, brought the bill for bitcoin to $1,000 each at that time, and if that were the case, no one would use it.

早期中本聪对比特币的硬分叉也做过设计，在bitcoin.org上面有关于怎样扩大区块的一个伪代码，但是这段代码已经成为历史了，BCH更加符合我理解的比特币。

It was also designed for the early hard fork in Bintbitcoin, with a fake code on bitcoin.org about how to expand blocks, but the code has become history, and BCH is more in line with the bitcoin I understand.

BCH遇到最大的阻力是支付网络的构建，BCH要做现金，主打支付。整个支付网络的搭建是非常缓慢的，类似于早期的微信或者支付宝，但是一旦搭建起来，整个网络效应非常强。

The biggest resistance to BCH is the construction of the payment network, the BCH is going to make cash, and the main payment. The whole payment network of

BCH并不拒绝闪电网络

BCH does not reject the Lightning Network

如果BCH不扩容，就会面临高手续费的问题，而目前大区块是最简单的实现扩容效果的方式。目前，以太坊、BTC都会出现拥堵，BCH即便大量交易，拥堵状况也还好。BCH社区也比较支持闪电网络和侧链方案，只是目前闪电网络有自己的问题，最严重的是路由的问题。

If the BCH does not expand, the problem will be high, and the big blocks are the simplest way to achieve the expansion effect. For now, there will be crowding in Tai Chamber, BTC, even if there is a lot of deals, BCH will be better. The BCH community is also more supportive of the Lightning Network and the Side Chain Program. is just a problem with the current Lightning Network. is the most serious one of routers.

闪电网络采用类似的路由系统去设计，而路由比较稳定，比如我们从中国访问美国，下次再走这条线路还是通的。但是闪电网络不一样， 因为每个节点的状态都会改变，只要发完交易就会改变。当你发一笔交易之后，这个节点下一秒就不知道能不能弄了，所以整个路由的系统是特别慢的。

The lightning network is designed using a similar route system, and the route is more stable, for example, when we visit the United States from China, and the next time we take this route, it's going to work. but the signal network is different, because every node changes its state, and once it's done, it's going to change. You don't know if this node is going to work again. The whole route system is very slow.

闪电网络已经发展三年了，依然没有大规模地运用。反观以太坊，它不断地去扩容，去解决自己链上交易的问题。

The lightning network has been growing for three years and is still not being used on a large scale. In retrospect, it is constantly expanding to deal with its own chain of dealings.

分片也是BCH的探索方向，但是分片也有自己的问题。去中心化的特点，所有人各自拥有一份全部的数据。然而，分片是要分裂所有的数据，大多数人只会拥有一部分的数据，所以不利于去中心化。分片现在最大的问题是如何解决跨片通信，很多人都在探索。

It's also the direction of BCH's exploration, but it also has its own problems. Decentralization is characteristic of all people having a full copy of the data. , however, the fragments are meant to divide all the data, most people have only a portion of the data, so it's not conducive to decentralization. The biggest problem now is how to solve cross-sectional communications, and many people are exploring it.

为什么bitcoinABC团队会出现资金问题？

Why would the bitcoin ABC team have a funding problem?

BCH有几个开发团队，比如bitcoinABC、bitcoin Unlimited、bitcoinXT，还有一些其他的开发团队。bitcoinABC是BCH社区的主要开发者。

BCH has several development teams, such as Bitcoin ABC, bitcoin Unlicented, bitcoinXT, and others. BitcoinABC is the main developer of the BCH community.

bitcoinABC需要资金扩大团队但又不接受机构和矿工的投资，是因为他们想保证自己的独立性，这是我的理解。BCH开发者社区比较偏极客，他们对于中本聪早期的思想强烈认可。

bitcoinABC needs funds to expand its team, but does not accept investments from institutions and miners because they want to guarantee their independence, which is my understanding. BCH developers are more polarized and strongly agree with the early thinking of medium-breeding.

在我们看来，bitcoinABC团队资金的问题，是因为整个协议的设计没有涉及开发者的激励机制。目前，整个共识只有矿工能拿到货币发行奖励，但是开发者却没有，实际上开发者做出的贡献很大，因此这是一个需要解决的问题。

In our view, the problem with team funding in bitcoin ABC is that the whole agreement was designed without incentives for developers. At present, the whole consensus is that only miners can get a monetary incentive, but not the developers, and the developers actually make a huge contribution, so this is a problem that needs to be addressed.

探索创新隔离区

Explores Innovative Isolation Zones

现在公链的竞争非常激烈，技术演进也非常快。比特币会不会被淘汰？这件事很难说。我个人认为不会，但市值占比会逐渐地下降。只有保持自己的快速迭代才能快速进步，这也是BCH社区有可能竞争过其他公链的一个潜在逻辑。

Now the public chain is very competitive, and the technology is very fast. It's hard to say that bitcoin will be eliminated. Personally, I don't think it will, but the market value ratio will decline.

但市值大了之后，想要保持和之前一样的快速迭代，可能性较小。因此，需要另一种方案——建立创新隔离区。在创新隔离区做的操作不会影响到主链，既保证主链安全，又能够有一定的创新的特性。我们目前还在思考如何实现这种方式。

But when the market is large, it's less likely to be able to maintain the same speed as before. therefore needs another option -- the creation of an innovative area of separation. Operation in an innovative area of separation will not affect the main chain, ensuring its safety and having some innovative features. We're still thinking about how to do it.

治理模型最重要

The most important governance model is

共识、治理、性能三者，我觉得治理的方式是比较重要的。共识是建立在一定的治理模型上的，比特币就是建立在PoW治理模型上的，通过算力投票的方式来实现治理。区块链的发展日新月异，如果有好的治理模型，共识和性能都能得到很好的解决方案。

I think the way governance works is more important than the way it works. The consensus is based on a governance model. The Bitcoin is based on a PoW governance model, and governance is achieved by means of arithmetical voting. The development of the block chain of

我们很难给共识一个明确的定义。比如社区总共有100人，现在我们对社区提出了一个更改意见，如果社区中有1个人不同意，我们应不应该推进这种更改呢？如果是2个人、5个人、10个人、50个人不同意的情况下，我们应不应该推进这种更改呢？这涉及治理模型的问题，如果有一个好的治理模型，那么就能更好地推动共识的演进。

It's hard for us to give a clear definition of consensus. For example, there are 100 people in the community, and now we're proposing a change in the community. If one of them doesn't agree, should we push it? If two people, five people, 10 people, 50 people disagree, should we push it? It's a question of governance models, and if there's a good governance model, then we can better move the consensus forward.

性能也是如此，因为性能的发展是一个不断演进的过程。性能在很多时候都要做一定程度的改进，这就有可能牺牲掉一些东西，这就需要治理模型去推动这个过程。治理模型做好了，性能问题才能得到比较好的解决。

The same is true of performance, because performance development is an evolving process. In many cases, there is a degree of improvement in performance, which could be sacrificed, and this requires a governance model to drive the process. governance models are well developed, so that performance issues can be better addressed.

公链10000步，当前10步都没走到

如果整个公链的发展有10000步，那么现在可以说才走了几步而已，可能连10步都没走到。

If there's 10,000 steps in the whole chain, it's only a few steps, maybe 10 steps.

去年加密猫导致以太坊拥堵，一个加密猫就把以太坊堵死了，更别说以后企业级应用了。因此，公链还存在很大的性能问题。

Last year an encrypt cat caused a crowding up of the Etherm, and an encrypt cat blocked the Etherm, let alone later applied at the corporate level. So, there's still a lot of performance problems in the public chain.

公链还面临一个瓶颈，怎样让区块链真正融合到现有的经济体。我们在解决公链性能问题的基础上，还要把区块链真正用到整个经济活动中。

There's also a bottleneck in the public chain of

未来很多的联盟链的发展会依赖于整合公链，整合公链会成为企业级应用的基础，因为它稳定可靠安全。

The development of many of the future union chains will depend on the integration of public chains, which will form the basis for business-level applications, as it is stable and secure.

未来公链的竞争会非常激烈，发展速度会非常快，BCH、以太坊等公链都在不断地演进。公链发展到最后只有几条，大概2-3条。对大部分公链而言，未来的发展会越来越难。

In the future, the public chain will be very competitive, it will grow very fast, and the BCH, Ether, etc., will continue to evolve. The public chain will last only a few, roughly two to three. For most of the public chain, the future will become more difficult.
