【AMA】闪电网络三巨头首次聚齐,质疑与夸奖,我们照单全收!

嘉宾 Samson Mow,Pierre-Marie,Alex Bosworth

关于闪电网络:随着用户量和普及度的增加,比特币每秒7笔的交易已经无法满足用户需求,闪电网络因此诞生。这是一种“Layer 2”(二层)支付协议,搭建在比特币区块链上。有了闪电网络之后,我们不需要在区块链上记录每笔交易。用户可以在基于比特币区块链的这一层互相建立支付通道,自由地进行交易。一旦双方的交易确定结束,就可以关闭通道,将…

    闪电网络发展缓慢,同时面对扩容和分片等新技术的竞争。闪电网络如何脱颖而出

    AMA官方翻译小助手 水手 回复Alex Bosworth 发表于2020-03-27 15:35:09

    Alex Bosworth:

    我不相信sharding进展很快,因为我已经听说过很长时间了,但我没有看到任何重大成果,但我不是这方面的专家。

    随着时间的推移,闪电网络能做的最大的事情就是帮助更多的企业和个人认识到用闪电解决问题的方法。我们的重点是帮助更多的商人和交易所更私密、更便宜、更快地转移资金,我们正在稳步取得进展。

    Alex Bosworth 水手 回复亚洲铜 发表于2020-03-27 11:44:55 嘉宾
    I don't believe that sharding is moving quickly since I've heard about it for a very long time but I haven't seen any major results, but I'm not an expert in that.

    The biggest thing that Lightning can do to stand out over time is to help more businesses and individuals realize solutions to their problems with Lightning. Our focus is on helping more merchants and exchanges move more money more privately, cheaply, and quickly and we are steadily making progress.
    AMA官方翻译小助手 水手 回复Samson Mow 发表于2020-03-26 18:03:18

    Samson Mow:

    闪电网络的发展实际上非常迅速。因为闪电网络是二层方案,所以它不需要基础层的共识来部署新技术。这使得它的开发变得容易很多。

    至于分片,好像依然停留在概念阶段,没有实际的部署。


    Samson Mow 水手 回复亚洲铜 发表于2020-03-26 18:02:18 嘉宾
    LN development is actually very rapid. Since LN is layer-2, it does not have to rely upon consensus at the base layer for new technology to be deployed. This makes it easier to develop for.
    As for sharding, it seems to be only an idea currently with no practical implementations.
    AMA官方翻译小助手 水手 回复Pierre-Marie 发表于2020-03-26 17:04:11

    Pierre-Marie

    我认为你的说法不正确。 LN的发展速度令人惊讶,甚至我们无法跟踪正在发生的一切(也太多了)。 另外,我们不要将已部署的有效解决方案(即使仍在开发中)与你说的那些未发布的东西进行比较。

    Pierre-Marie 水手 回复亚洲铜 发表于2020-03-26 16:42:17 嘉宾
    I don’t think that is accurate. The pace of development in Lightning is astonishing, even us can’t keep track of everything that is happening, there is just too much. Also, let’s not compare deployed, working solutions (even if still in development) with stuff that is not released.
  • 木兰北风 队长 发表于2020-03-24 22:05:52

    跨链技术越来越多,越来越广,发展的很迅速,对比闪电网络的发展缓慢,闪电网络还有优势吗,如何竞争,靠什么在竞争中脱颖而出? 面对发展的新形势,为了适应并发挥优势,闪电网络会做哪些改进?

    AMA官方翻译小助手 水手 回复Alex Bosworth 发表于2020-03-27 15:36:29

    Alex Bosworth:

    Lightning是一个跨链解决方案,它可以跨多种类型的系统运行。我认为这是它最大的优势,任何东西都能与闪电网络连接。

    网络系统的效用随着它的增长而增加。如果只有少数人拥有电话,那么一部电话就不是很有用。如果几乎每个人都有电话,那么电话就成了普遍需求。

    基于这个原因,我相信Lightning的制胜策略是与尽可能多的用户交互,不管他们使用的是什么系统。

    Alex Bosworth 水手 回复木兰北风 发表于2020-03-27 11:46:20 嘉宾
    Lightning is a cross-chain solution, it can function across multiple types of systems. I think that is its biggest strength, that anything can interface with Lightning.

    The utility of a networked system increases as it grows. If you have only a few people owning telephones, a single telephone isn't very useful. If almost everyone has a telephone, that makes having a telephone basically a requirement.

    For that reason I believe the winning strategy for Lightning is to interface with as many users as possible, no matter what system they are using.
    AMA官方翻译小助手 水手 回复Samson Mow 发表于2020-03-26 18:03:58

    Samson Mow:

    闪电网络的优势在于不受链上共识的限制。这意味着闪电网络的发展非常迅速。因此,围绕着闪电网络正在开发许多令人兴奋的新技术。竞争对手则必须等待共识的达成,才能添加新技术,这意味着与闪电网络相比,整体开发速度较慢。

    Samson Mow 水手 回复木兰北风 发表于2020-03-26 18:02:51 嘉宾
    LN’s advantage is not being constrained by on-chain consensus. This means development for LN can be very rapid. So much new exciting technology is being developed for LN as a result of this. Competitors have to wait to gain consensus to have their tech added, which means development overall is slow compared to LN.
    AMA官方翻译小助手 水手 回复Pierre-Marie 发表于2020-03-26 17:43:20

    Pierre-Marie

    跨链支付在LN中是可行的,但我不确定它们是否有用。 我一定不是唯一有这种想法的,因为似乎很少有人在为此工作。

    Re:竞争对手们, LN属于比特币。 LN不会与其他区块链竞争,比特币会——但我们都知道谁会赢。


    Pierre-Marie 水手 回复木兰北风 发表于2020-03-26 16:42:47 嘉宾
    Cross-chain payments are feasible with Lightning, but I’m not sure if they are that useful. I must not be the only one thinking that, since few people are seemingly working on it.
    Re: competitors. LN is Bitcoin. LN isn’t competing with other blockchains, Bitcoin is --and we all know who is going to win.

    如何看待闪电网络不够去中心化的问题,是否存在黑客利用其特性操控整个网络的可能?

    AMA官方翻译小助手 水手 回复Alex Bosworth 发表于2020-03-27 15:40:57

    Alex Bosworth:

    又是一个关于去中心化的问题,对于黑客来说,可能存在热钱包和活动节点的安全漏洞。

    对通道和支付规模有安全限制的一个原因是降低了闪电网络作为黑客攻击目标的吸引力。

    当我们解除限制的时候,我希望我们也能看到网络对黑客的攻击更加强硬,因为拒绝服务和盗窃资金是一个严重的问题,在网络中拥有更多的资金会使问题变得更加严重。

    Alex Bosworth 水手 回复NeoKID 发表于2020-03-27 11:47:29 嘉宾
    Another question asked about decentralization, but for hacking it is possible that there would be security vulnerabilities with hot wallets and live nodes.

    One reason that there have been safety limits on the size of channels and payments is to reduce the attractiveness of Lightning as a target for hackers.

    When we lift the limits, I hope that we will also see more hardening of the network against hackers because denial of service and theft of funds is a serious concern, made much more serious by having larger amounts of money in the network.
    AMA官方翻译小助手 水手 回复Samson Mow 发表于2020-03-26 18:04:28

    Samson Mow:

    不可能,闪电网络不是中心化的。

    Samson Mow 水手 回复NeoKID 发表于2020-03-26 18:03:16 嘉宾
    No, that’s very unlikely because LN is actually not centralized.
    AMA官方翻译小助手 水手 回复Pierre-Marie 发表于2020-03-26 17:44:05

    Pierre-Marie

    您实际上已经回答了自己的问题:-)。 被黑客入侵的风险是中心化的一个限制因素,因为节点越大,对黑客的诱因就越大。 真正重要的是,LN是无需信任的,您不必担心某些LN节点是否被黑客入侵(即使它是您的直接使用的节点之一)。

    Pierre-Marie 水手 回复NeoKID 发表于2020-03-26 16:43:55 嘉宾
    You are kind of answering your own question :-). The risk of getting hacked is a limiting factor of centralization, because the larger a node gets, the larger the incentive for hackers. What’s really important is that, Lighting being trustless, you don’t have to worry if some Lightning node gets hacked (even if that’s one of your direct peers).

    闪电网络操作到底有多复杂?有没有操作流程?

    AMA官方翻译小助手 水手 回复Alex Bosworth 发表于2020-03-27 15:41:37

    Alex Bosworth:

    Lightning是一个底层协议,它本身相当复杂。作为用户或开发人员使用的复杂程度取决于与之交互的软件类型。

    我做了一些测试网站,用测试资金来感受它。一个网站是一个保管钱包htlc.me,它允许您发送和接收闪电测试网付款。另一个网站是testnet.yalls.org,它允许您在Lightning上测试购买。

    我认为Lightning可以变得比传统的链上钱包更简单,但这取决于开源开发社区的实现。一些基于LND的钱包正在进行这项工作,它们是Breez、Zap/Strike、保管钱包BlueWallet,我制作了一些开源的node.js库来帮助开发Lightning应用程序。

    对于一个商家来说,闪电网络还有一个额外的问题,那就是管理他们的流动性。如果没有“流入流动性”,即网络上的其他对等方通过通道向他们承诺资金,他们将无法收到付款。这是一个很难解决的问题,我一直致力于用Lightning Labs的Lightning Loop服务轻松解决这个问题,该服务帮助Lightning企业管理其流动性。

    Alex Bosworth 水手 回复0TPJlZ1J 发表于2020-03-27 11:48:34 嘉宾
    Lightning is an underlying protocol and it is fairly complex by itself. How complex it would be to use as a user or a developer would depend on the kind of software you would use to interact with it.

    I've made some test websites that use test money to get a feel for it. One website is a custodial wallet htlc.me which allows you to send and receive Lightning testnet payments. Another website is testnet.yalls.org which allows you to test purchasing on Lightning.

    I think Lightning can be made to be even simpler to use than the traditional on-chain wallets, but that is up to the open source development community to achieve. Some LND-based wallets working on this are Breez, Zap/Strike, the custodial BlueWallet, and I've made some open source node.js libraries to help make it easy to develop Lightning applications.

    For a merchant, they have an additional problem with Lightning which is to manage their liquidity. Without "inbound liquidity", meaning other peers on the network committing capital in channels to them, they will not be able to receive payments. That's a difficult problem to solve and I've been working on making an easy way to solve that with the Lightning Loop service from Lightning Labs that helps Lightning businesses manage their liquidity.
    AMA官方翻译小助手 水手 回复Samson Mow 发表于2020-03-26 18:05:02

    Samson Mow:

    用起来很简单。你可以下载一个app、创建一个钱包,然后在几分钟内发送或接收比特币。我推荐你用Blue Wallet,因为用户界面很棒。

    Samson Mow 水手 回复0TPJlZ1J 发表于2020-03-26 18:03:41 嘉宾
    It’s very easy to use. You can download an app, create a wallet, and send or receive BTC in a matter of minutes. I would recommend Blue Wallet as it has a nice UI.

    A lot of Lightning development is done with people around the world so it has not made a huge difference yet. I worked from home part of the time before, now I work from home all of the time. For me things are OK but I anticipate things in the US getting a bit worse before they get better.

    The biggest problem I have is that I have a medical problem with my hearing and the doctor cannot help me right now because it is not an essential procedure. I'll have to wait until non-essential procedures are allowed again.

    Alex Bosworth:

    任何一种系统都会受到攻击,比特币早期的大部分工作都是针对关闭拒绝服务问题而开发的。区块链仍然有许多未解决的隐私、安全和服务可用性问题,即使已经做了所有的工作来确保它。

    事实上,对于闪电网络的安全性来说,有关于其潜在问题的文章是个好兆头。流行的开源协议的优势在于,来自世界各地的研究人员可以评估弱点,提出解决方案,帮助确定最重要问题的优先级。因为每个系统都有问题,如果你没有看到文件和听到问题,这可能意味着它们仍然存在,但只是没有得到解决。

    对于闪电网络,我们的主要防线就是区块链。BOLT 11 Lightning invoices有一个备用地址,其中列出一个链上地址或多个地址,用作Lightning的替代。如果你不能使用闪电支付,你可以使用区块链代替。我们也在研究如何把闪电基金花在链上,比如Lightning Loop和通道拼接。

    第二个主要的防御措施是我们有一个内置的方法来要求小额支付。因为系统是为隐私而设计的,所以很难编写软件来区分攻击系统的人和合法使用系统的许多人。如果有太多的活动,潜在的DoS缓解措施可能是要求对过度使用进行小额支付。

    并不是所有的开发都是为了解决这些问题,这是有意义的,因为如果由于其他问题限制了对Lightning的使用,那么闪电网络就没有防弹的意义。

    这是我们在LND工作时经常考虑的事情,一般来说,每一个版本对攻击都会变得更具弹性,但还有很长的路要走。

    Any kind of system is subject to attacks, much of the early work in Bitcoin was development on closing denial of service issues. The Blockchain still has many unsolved privacy, security, and service availability issues even with all of the work that has been done to secure it.

    It's actually a good sign for the security of Lightning that there are papers on its potential problems. The advantage of popular open source protocols is that researchers from around the world can evaluate weaknesses, propose solutions, help prioritize the most important problems. Since every system has problems, if you aren't seeing papers and hearing about problems it probably means that they are still there but just not being addressed.

    With Lightning our main line of defense is the Blockchain. BOLT 11 Lightning invoices have a fallback address which lists an on-chain address or multiple addresses for using as an alternative to Lightning. If you cannot make a payment using Lightning, you can use the Blockchain instead. We are also working on ways to spend Lightning funds on-chain, like Lightning Loop and channel splicing.

    The second major defense is that we have a built-in method for requiring micropayments. Because the system is designed for privacy, it is difficult to write software to discriminate between someone attacking the system vs many people legitimately using the system. Potential DoS mitigations can be to require micropayments for excessive usage if there is too much activity.

    Not all development is oriented towards addressing these problems, which does make sense because if usage on Lightning is limited due to other issues then there is no point in the Lightning Network being bulletproof.

    This is something that we do think about a lot when working in LND and generally speaking every release becomes more resilient to attacks, but there is a long way to go.

    保障安全始终是一个持续的过程。这就是为什么有一个强大的开发社区是如此重要,我们很幸运,有一个强大的闪电网络开发社区。你引用的有关DOS攻击的论文,其中一位作者是来自Blockstream的Christian Decker博士。为了发现和解决问题,我们必须调查和批判性地分析闪电网络。这个过程很正常,而且会让闪电网络变得更强大。

    Security is always an ongoing process. That’s why having a robust development community is so important, and we are fortunate to that a great one for the LN. If you look at the paper you cited for DOS attacks, one of the authors is Dr. Christian Decker from Blockstream. We have to probe and critically analyze LN in order to find and address issues. It’s a normal process and will lead to LN becoming more robust.

    中本聪曾在比特币创世区块上写下2019年1月3日英国泰晤士报的头版标题“财政大臣正处于第二轮银行紧急援助的边缘”,你们认为当前的经济状况跟08年的金融危机相似吗?11年后,比特币再次与全球金融大动荡相遇,行情涨跌却不再按照技术派的分析走,而是跟随美股波动,它对比传统金融体系的优势体现在哪里?

    AMA官方翻译小助手 水手 回复Alex Bosworth 发表于2020-03-27 15:48:43

    Alex Bosworth:

    我认为金融市场的情况(与08年相比)非常相似,尽管一些金融机构已经针对2008年金融危机的直接原因做出了直接的改变。我不是股票或金融机构方面的专家,但我不同意比特币追随股市的说法。在过去的5年里,美国股市以非调整美元计价的涨幅仅为5%左右,比特币的涨幅约为2000%,所以我认为它们之间的关联度并不十分精确。

    我不相信比特币能取代传统市场,比特币交易更像是一个零和游戏,就像交易任何商品一样。我认为,比特币作为一种投资更类似于现金,但更具优势,因为它缺乏永久通胀的内在成本,也缺乏任何特定法币固有的边界限制。

    Alex Bosworth 水手 回复网速感人 发表于2020-03-27 11:53:12 嘉宾
    I think things are still pretty similar in the financial markets, although some financial institutions have made directed changes towards the direct causes of the 2008 financial crisis. I'm not an expert on stocks or financial institutions but I would disagree that Bitcoin has followed the stock market. Over 5 years the US stock market is up in non-adjusted dollars only around 5% and Bitcoin is up like 2000%, so I don't think they are very precisely correlated.

    I don't believe in Bitcoin as a replacement for traditional markets, and trading in Bitcoin is more like a zero-sum game, like trading any commodity. I believe Bitcoin as an investment is more similar to cash, but more advantageous because it lacks the built-in cost of permanent inflation and it lacks the inherent border limitations of any specific fiat.
    AMA官方翻译小助手 水手 回复Samson Mow 发表于2020-03-26 18:07:21

    Samson Mow:

    这次不一样。我们在2008年遭遇了金融危机,但这次的经济危机是由多个原因引起的,包括一个重大的黑天鹅事件:新冠病毒。全世界的工厂都关门了,人们也不怎么买东西了。市场需要现金,所以他们不得不卖掉所有能卖的东西,包括BTC。然而,比特币的价格并没有下跌那么多(比起股票的跌幅并不大),这意味着很多人仍然相信比特币,因为比特币可能是唯一能够对抗我们现在面临的恐怖的通货膨胀的货币。

    此外,我们还看到,比特币如今已与传统市场脱钩。价格正在恢复到7000美元,尽管注入了数万亿美元的流动性,股市仍然萎靡不振。距离比特币减半也只有48天了。在法定货币一次印刷数万亿美元的时候,比特币的通胀率将下降1.8%。没有比比特币更好的资产了。

    This time is different. We met the financial crisis back in 2008, but this time is an economic crisis caused by several reasons including one big black swan: the virus. The factories all over the world are shutted down and people don’t buy much products. The market needs money so they have to sell everything they can include BTC. However, the BTC price did not drop that much (not too much more than stocks) which means a lot of people still believe in BTC, since this might be the only currency that can fight the huge inflation we are facing right now.
    Also, we’re seeing that Bitcoin is decoupled from the traditional markets now. We’re recovering back to $7000 as the stock markets are still languishing despite trillions in liquidity injections. The Bitcoin halving is also just 48 days away. At a time when fiat currencies are printed trillions at a time, Bitcoin’s inflation rate will drop the 1.8%. There’s no better asset available to hold than Bitcoin.

    我认为我们所处的环境可能比2008年更糟。欧洲和美国的中央银行都已宣布了数万亿美元的救市政策,我们正在等待中国人民银行的举动,但可能会相似。 我不认为这最终不会成为储蓄税,只会增加比特币的价值主张。 短期价格波动可能是由于其他因素(恐慌,流动性需求)所致。 我们将在接下来的几个月中看到这种情况的发生,但是如果比特币的价格不能从所有这些中受益,我会感到惊讶。

    I think we are possibly in a worse environment than 2008. Central banks in Europe and the US have each made trillion-dollars announcements, we’re waiting for the PBOC’s move but chances are it will be similar. I don’t see how this won’t end up being a tax on savings, which only reinforces Bitcoin’s value proposition. Short term price movement probably is due to other factors (panic, need for liquidity). We’ll see how this plays out in the coming months but I would be surprised if bitcoin’s price does not benefit from all this.

    交易所拥有最大的比特币交易量,也是区块链圈子的主要用户。当更多的交易所采用闪电交易时,我认为这将使市场更高效,利差更低,因为交易员可以更高效、更快地转移资金。这也可能增加对闪电网络上路由节点的需求。使用闪电而不是区块链的交易所也可能直接降低链上费用。

    The most popular merchants that I have seen so far have been relaying payments to regular merchants through gift cards and credit purchases. Bitrefill and Fold allow you to pay with Lightning for a lot of regular purchases.

    Exchanges do the most Bitcoin trading volume by far and also are the main users of the Blockchain space. When more exchanges adopt Lightning I think it will enable more efficient markets with lower spreads, as traders can move funds around more efficiently and quickly. This may also increase demand for routing nodes on the Lightning Network. Exchanges using Lightning instead of the Blockchain may also directly lower on-chain fees.

    市场上已经有很多支付处理商了,他们做的都很好。其中大多数都支持闪电网络——例如 Globee和OpenNode。

    There are already many payment processors on the market and they all seem to be doing quite well. Most of them that I know already support LN too - for example, Globee and OpenNode.

    Pierre-Marie:

    比特币目前尚未广泛用于支付,我们正在押注它将来会。 至于交易所,鉴于Bitfinex,Bitstamp和BitMEx(可能还有更多?)都已开始集成LN,我们很快就会听到好消息。

    Bitcoin isn’t currently widely used for payments, we are making the bet that it will be in the future. As for exchanges, good news is we will soon find out, given that Bitfinex, Bitstamp and BitMEx (possibly more?) have all started integrating it.

    几位嘉宾,看到提到HODL,能不能透露下你们有多少比特币?在囤币或者买卖交易上,有什么经验可以分享?

    Alex Bosworth:

    我可以告诉你我的闪电节点目前的公共容量:大约27.5 BTC。这包括我同事的资金,他们把他们的资本分配给我,但实际的余额不方便透露。

    我不是一个真正的交易者,因为我只使用比特币,但我确实参与了闪电网络作为路由节点,这与交易有一些相似之处。当你用一个对等点创建一个通道时,你就在预测未来的路由费用。如果你选择明智,那么你将得到路由费回报。如果你选择不当,你将有一些链上成本来支付重新分配资金。

    I can tell you the current public capacity of my Lightning nodes: around 27.5 BTC. This includes the capital of my peers who assigned their capital in my direction though, and the actual balance is not broadcast.

    I'm not really a trader because I only use Bitcoin, but I do participate in the Lightning Network as a routing node and that has some similarities to trading. When you create a channel with a peer, you are anticipating future routing fees towards that peers. If you choose wisely then you will be rewarded with routing fees. If you choose poorly you will have some on-chain costs to pay to reassign the capital.
