以太坊基金会发布了两个以太坊2.0攻击网，供黑客破解以换取漏洞赏金。

The Ethereum foundation has released two Ethereum 2.0 attack networks for hackers to crack in exchange for vulnerability rewards.

以太坊基金会发布两个ETH 2.0攻击网供黑客攻击新闻。

Ethereum foundation releases two eth 2.0 attack networks for hackers to attack.

以太坊基金会已经基于现有的稳定客户端发布了针对以太坊2.0的公共“攻击网”。

The Ethereum foundation has released a public "attack network" for Ethereum 2.0 based on its existing stable clients.

这些网络旨在为安全研究人员提供一个沙盒环境，在这里他们可以尝试通过利用客户端中的潜在问题来破坏以太坊2.0的网络。目前，有两个基于Lighthouse和Prysm客户端的“ beta-0”攻击网，分别由Sigma Prime和Prysmatic Labs构建。

These networks are designed to provide security researchers with a sandbox environment where they can attempt to disrupt the Ethereum 2.0 network by exploiting potential problems in the client. At present, there are two "beta-0" attack networks based on lighthouse and Prysm clients, respectively built by sigma prime and prysmatic labs.

根据周一发布的公告，攻击网是“真实网络”，尽管存在一些限制。值得注意的是，只有4个带有128个验证器的节点已被部署到网络中，而以太坊2.0预计将有数千个节点。

According to the announcement released on Monday, the attack network is a "real network", despite some restrictions. It is worth noting that only four nodes with 128 validators have been deployed to the network, while Ethereum 2.0 expects to have thousands of nodes.

存款也未启用，这意味着黑客将需要“尝试基于非验证器的攻击”。

Deposits are also not enabled, which means hackers will need to "try non verifier based attacks.".

攻击者的目标是“通过任何必要的手段”在单一网络上“防止确定连续16个epoch”。这意味着利用该漏洞将需要使以太坊2.0网络至少102分钟（1小时42分钟）内无法使用且不安全。

The attacker's goal is to "prevent the determination of 16 consecutive epochs" on a single network "by any necessary means". This means that exploiting this vulnerability will require that the Ethereum 2.0 network will be unavailable and insecure for at least 102 minutes (1 hour, 42 minutes).

每个epoch由32个插槽（slot）组成，在这些插槽中可以提出块。每个插槽持续12秒，在最佳条件下大致相当于出块时间。在每个阶段结束时，将重新组合验证器以维护网络的安全性。

Each epoch consists of 32 slots in which blocks can be raised. Each slot lasts for 12 seconds, which is roughly equivalent to the block time under optimal conditions. At the end of each phase, the validators are recombined to maintain network security.

通过这种方式成功破坏网络的个人黑客和特定组织将获得5000美元的赏金。每个网络都有其自己的赏金，尽管单个实体只能得到一个。

Individual hackers and specific organizations that successfully disrupt the network in this way will receive a $5000 reward. Each network has its own reward, although a single entity can only get one.

以太坊2.0持续进步

近几个月，以太坊2.0的第0阶段取得了进展，团队最近在更新的0.12.1规范上发布了一个名为Altona的新的多客户端测试网。测试网有望成为最后一个主要由开发人员运行的“ devnet”，而不是面向公众的全面测试网。

In recent months, phase 0 of Ethereum 2.0 has made progress, and the team recently released a new multi client test network called Altona on the updated 0.12.1 specification. Test network is expected to be the last "DEVNET" run mainly by developers, rather than a comprehensive test network for the public.

攻击网络是这种转变的重要组成部分，因为它们会激励其他人发现简单测试可能无法发现潜在的漏洞和的问题。

Attacking networks is an important part of this transformation, because they encourage others to discover potential vulnerabilities and problems that simple tests may not be able to detect.

但是，其他因素可能会削弱公众的乐观情绪。例如，一些客户开发团队似乎落后了，他们的节点无法加入共享的测试网。

However, other factors may weaken public optimism. For example, some customer development teams seem to be lagging behind and their nodes cannot join the shared test network.

此外，社区必须决定是什么让以太坊 2.0可以用于主网，随着系统继续进行测试，可能还要等待数月。

In addition, the community must decide what makes Ethereum 2.0 available on the main network, which may take months as the system continues to be tested.

以太坊2.0研究人员Justin Drake认为，鉴于几个月的测试和节假日的影响，主网最可能的启动日期是2021年1月。然而，以太坊的联合创始人Vitalik Buterin并不认同这个时间表，他认为即使牺牲了一些谨慎性，第0阶段也应该在2020年启动。

Justin Drake, an Ethereum 2.0 researcher, believes that the most likely start-up date for the main network is January 2021, given the impact of several months of testing and holidays. However, vitalik buterin, the co-founder of Ethereum, does not agree with the timetable. He believes that even at the expense of some caution, phase 0 should start in 2020.
