Blockstream缪永权:SegWit2x只会导致网络分裂,并产生另一个山寨币

2017年8月24日,区块高度481824,隔离见证正式激活。自2015年12月Bitcoin core开发者团队首此提出隔离验证方案,到正式落地,比特币经历了它有史以来耗时最长的一次技术更新。(了解SegWit历程详见:《通往SegWit的漫长之路:比特币最大的协议升级是如何成为现实的》)

不过,尽管隔离见证已经激活,但关于比特币扩容的讨论远远没有结束。现在,比特币社区的焦点也逐渐转移到了预计在11月发生的SegWit2x硬分叉。

Blockstream一直是隔离见证的坚定支持者,最近,他们还将比特币送上了太空(详见:《你没听错,比特币技术公司Blockstream真的要发射卫星了》)。首席战略官缪永权在最近接受了巴比特专访,跟我们聊了聊比特币卫星项目和比特币未来走势。

8btc:发起比特币卫星项目的初衷是什么?
What is the original intention of launching a Bitcoin satellite project?

缪永权:像比特币这样的全球金融网络需要全球覆盖和冗余——而这正是我们希望通过Blockstream卫星所实现的东西。该项目还使运营比特币完整节点的成本更低,而对于没有互联网的地区来说,它也可以接收区块链的数据。总的来说,Blockstream卫星项目让比特币变得更加强大。

A global financial network like Bitcoin requires global coverage and redundancy – that’s what we hope to bring forth with Blockstream Satellite. The project also makes it cheaper to run a Bitcoin full node, and for areas without internet to receive the blockchain. Overall, the Blockstream Satellite project makes Bitcoin far more robust.

8btc:此前也有人曾尝试过发射比特币卫星,Jeff Garzik的BitSat计划最后还是无疾而终。我们都知道这项工作不那么简单,能否用一些具体的例子说明这项工作的难度?为什么在现在这事儿非干不可了?
Previously, some people have tried to launch a special coin satellite, Jeff Garzik’s BitSat plan died in the end. We all know that this project is difficult, but it is difficult to imagine the details, can you use some specific examples to illustrate the difficulty of this project? Why does it have to be done now?

缪永权:Blockstream与Jeff Garzik采取了不同的路线。我们租用商用卫星上的空间,并通过地面站(称为“远创送站”)将区块数据传送到卫星,然后再转播至全球。 BitSat的概念是有缺陷的,因为它是基于立方体卫星,一种在位于地球表面以上650至1600公里之间的低地球轨道运行的小卫星。立方体卫星没有太多用处,它们的轨道在几年内就会衰变,而且你需要很多立方体卫星来实现全球覆盖。我们使用的卫星是地球同步轨道上的高功率商业卫星,距地球表面35776公里。

该项目实际上并不难实现,因为我们拥有一个非常有经验的团队在做这项工作。现在是一个好时机,因为随着新的扩容技术上线, 交易费用将大大降低,我们应该找到一种方法使比特币网络能够面向全球的大量受众群,甚至那些没有互联网的用户。

Blockstream took a different route than Jeff Garzik. We leased space on commercial satellites and setup ground stations, which are called teleports, to beam blocks up to the satellites, which are then rebroadcast to Earth. The BitSat concept was flawed as it was based on CubeSats which are very small satellites that live in low Earth orbit, which is between 650-1600 kilometers above the surface of the Earth. CubeSats don’t have much power, their orbits decay within a few years, and you would need a lot of them to have global coverage. The satellites we’re using are high power commercial satellites in geosynchronous orbit, which is 35,786 kilometers above the surface of the Earth.

The project wasn’t actually that hard to do as we had a very experienced team working on it. Now is a good time because with the advent of new scaling technologies coming online, which will lower transaction fees, we should look for ways to reach a large audience base around the world, even those without internet access.

8btc:比特币卫星运行之后能带来的实际作用有哪些?
What are the actual effects that the Bitcoin satellite can bring after it is running?

缪永权:最重要的是,如果出现任何互联网故障,Blockstream卫星将阻止网络分裂。有时,海底电缆会被切断,而且由于比特币网络依赖于持久的同步性,网络可能分裂,人们也会损失金钱。全球卫星覆盖将减轻这种风险。

Blockstream卫星降低了运行完整节点的成本。比特币区块链每个月增长数十亿字节,而且用户现在可以通过卫星免费获得这些数据——这降低了运行节点的成本,让用户更有可能自己运行节点。网络上的节点越多,比特币网络的安全性就越高。

Blockstream卫星还引入了新的用例。在某些地方,整个村落的人可以将资金聚集在一起,建立一个卫星节点,然后让人们通过WiFi或meshnet连接智能手机钱包,然后通过SMS网关,比如Pavol Rusnak,或者是bi-directional Ku或l-band互联网服务(可以在市场上买到,且与Blockstream无关)广播交易。

目前,我们只是广播区块,但之后我们可以提供双向服务。这将允许比特币在任何电价低廉但没有可靠地互联网的的偏远地区进行开采 。

Most importantly is that Blockstream Satellite will prevent a network split if there is any internet failure. Sometimes an undersea cable can be cut, and as the Bitcoin network relies on constant synchronization, the network could suffer a split and people losing money. Global satellite coverage will mitigate that risk.

Blockstream Satellite reduces the costs of running a full node. The Bitcoin blockchain grows by several gigabytes each month, and users can now get that data for free through the satellite – this reduces the cost of to run a node and makes it more likely that a user will spin one up. The more full nodes that are on the network, the more secure the Bitcoin network is.

Blockstream Satellite also introduces new use cases. A village somewhere could pool together funds to setup a satellite node, and then allow people connect smartphone wallets over WiFi or meshnet and then broadcast transactions via SMS gateways such as SMSPushTX, by Pavol Rusnak, or bi-directional Ku or L-band internet services (available commercially and unrelated to Blockstream Satellite).

Currently, we’re only broadcasting blocks, but later we could offer bi-directional service. That would allow Bitcoin mining in remote locations where there may be cheap power, but no reliable internet.

8btc:发射这些卫星的大致花费是多少呢?
What is the approximate cost of launching these satellites?

缪永权:我们租用了商业卫星,其成本取决于使用和带宽。

We’re leasing commercial satellites and the cost depends on usage and bandwidth.

8btc: Blockstream的比特币卫星只支持一种比特币扩容方案,还是会支持多种?
Does Blockstream’s Bitcoin Satellite support only one Bitcoin scaling program, or will it support multiple?

缪永权:我不确定我理解了这个问题。对于比特币来说,唯一可行的扩容项目是隔离见证和第二层技术,但如果你问的是山寨币,我可以澄清的是,Blockstream卫星目前只支持比特币。我们没有计划支持Bcash,隔离见证2x货币 (目前人们这种可能由分叉产生的货币称为B2X),或者任何其他的山寨币。

I’m not sure I understand the question. The only viable scaling program for Bitcoin is SegWit and Layer 2, but if you’re asking about altcoins, I can clarify that Blockstream Satellite will only support Bitcoin for the time being. We have no plans to support Bcash, SegWit2x Coin (currently people are referring to the potential coin as B2X), or any other altcoins.

8btc:你认为原定在11月的SegWit2x能够顺利实施吗?
Do you think the originally scheduled SegWit2x in November can be implemented smoothly?

缪永权:隔离见证2x只会导致网络分裂,并产生另一个山寨币。 这个山寨币的意图是成为比特币,但由于没有任何共识,这是不可能的。 “纽约共识”的签署人中并没有包含任何Bitcoin Core开发人员,并且许多最初的签署人实际上也已经退出了。 此外,一些公司不能代表整个比特币生态系统,也不能为所有比特币用户做出决定。 如果他们可以这样做,那么就没有必要使用比特币了 – 我们可以使用任何由几方控制的中心化系统。 纽约共识的签署人应该尊重更广泛的社区的愿望,停止将会破坏市场、造成价格下跌以及产生新山寨币的的硬分叉计划。

SegWit2x can only cause a network split and give rise to another altcoin. Its intention was to become Bitcoin, but as there is no consensus whatsoever, that is impossible. The signers of the New York Agreement did not include any of the Bitcoin Core developers and also many of the original signers have actually pulled out as well. Moreover, a few companies cannot speak for the entire Bitcoin ecosystem, nor make decisions for all Bitcoin users. If they could do that, then there is no point to having Bitcoin – we could use any centralized system controlled by a few parties. The signers of the NYA should respect the wishes of the broader community stop their hard-fork plan which will disrupt the market, cause a price drop, and result in yet another altcoin being created.

8btc:现在比特币的市值已经突破700亿美金(注:该采访发生在8月中旬),这与此前对于分叉的市场预期似乎是相悖的,你怎么看待BCC的诞生,和最近比特币价格的持续上涨?分叉前的市场预测是什么?
Now the market value of Bitcoin has exceeded 70 billion US dollars, which contradict with the market prediction before the fork, how do you think of the birth of BCC, and the recent bitcoin prices constantly rising? What was the market prediction before the fork?

缪永权:我认为市场上的很多人都对BCC感到十分困惑,因为BCC使用了比特币的名字。 然而,BCC确实实施了重放保护,所以网络的中断的概率是很小的。 然而,SegWit2x拒绝实施重放保护,所以这会迫使许多交易所停止交易,直到两种货币可以混合。

价格上涨对比特币来说是好的。 我认为,由于某些矿池的不断威胁,价格被人为地压低。 我已经说过很多次,隔离见证被激活,价格会上涨,我们也看到了这就是正在发生的事情。 市场认识到了隔离见证以及如闪电之类的第2层解决方案带来的好处。 隔离见证2x应该停止,因为它只会损害比特币的价格。 所以,如果你重视你的比特币,那就跟那些声称支持隔离见证2x的矿池和企业谈谈吧 。声称是比特币的隔离见证2x 山寨币的出现不符合真正的比特币的最佳利益。

I think BCC is confusing to the marketplace because they are trying to use the Bitcoin name. However, they did implement replay protection so the disruption to the network was minimal. However, SegWit2x has refused to implement replay protection, so they would force many exchanges to halt trading until coins can be mixed.

The price rise is good for Bitcoin. I think the price was kept artificially low due to constant threats by certain mining pools. I’ve said many times that the price would go up once SegWit is activated and we see that’s exactly what happened. The market recognizes the benefits that SegWit and Layer 2 solutions like Lightning will bring. SegWit2x should be stopped though, as it will only harm the price. So if you value your Bitcoin, talk to mining pools and businesses that have stated they support it. The appearance of a SegWit2x altcoin claiming to be Bitcoin isn’t in the best interests of the real Bitcoin.

让我们把关注点再转移到比特币上来吧。比特币未来是否会三足鼎立,你怎么看?

      这种节点数量的变多,如同支付宝免费给你推送全网的账本,每个人可以低成本的备份所有支付宝账户余额,总计才不到1G个数据,这有任何意义吗?能增加去中心化水平吗?

        只会增加中心化,增加单点故障造成的影响

          它本来不过是与rootstock同样,也是个侧链企业,应该在原本的生态系统里做自己的工作就好了,它却自恃身份,想要控制整个生态。。。自大自傲

    没有BS/CORE同意的决定都不是共识,只有BS/CORE的同意的链,不管链上交易数量和难度安全性是否最大,都是共识链,只有卫星里发出的块,才是共识链,公有一个中心的链。
