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.
通过这种方法乐成粉碎网络的小我私家黑客和特定组织将得到5000美元的赏金。每个网络都有其本身的赏金，尽量单个实体只能获得一个。
以太坊2.0研究人员Justin Drake认为，鉴于几个月的测试和节沐日的影响，主网最大概的启动日期是2021年1月。然而，以太坊的连系首创人Vitalik Buterin并不认同这个时间表，他认为纵然牺牲了一些审慎性，第0阶段也应该在2020年启动。
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).
The Ethereum foundation has released a public "attack network" for Ethereum 2.0 based on its existing stable clients.
以太坊基金会宣布了两个以太坊2.0进攻网，供黑客破解以调换裂痕赏金。
Deposits are also not enabled, which means hackers will need to "try non verifier based attacks.".
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.
进攻网络是这种转变的重要构成部门，因为它们会鼓励其他人发明简朴测试大概无法发明潜在的裂痕和的问题。
可是，，其他因素大概会减弱公家的乐观情绪。譬喻，一些客户开拓团队好像落伍了，他们的节点无法插手共享的测试网。
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.
Ethereum foundation releases two eth 2.0 attack networks for hackers to attack.
存款也未启用，这意味着黑客将需要“实验基于非验证器的进攻”。
进攻者的方针是“通过任何必要的手段”在单一网络上“防备确定持续16个epoch”。这意味着操作该裂痕将需要使以太坊2.0网络至少102分钟（1小时42分钟）内无法利用且不安详。
The Ethereum foundation has released two Ethereum 2.0 attack networks for hackers to crack in exchange for vulnerability rewards.
近几个月，以太坊2.0的第0阶段取得了希望，团队最近在更新的0.12.1类型上宣布了一个名为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拓人员运行的“ devnet”，而不是面向公家的全面测试网。
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.
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.

另外，社区必需抉择是什么让以太坊 2.0可以用于主网，跟着系统继承举办测试，大概还要期待数月。
按照周一宣布的通告，进攻网是“真实网络”，尽量存在一些限制。值得留意的是，只有4个带有128个验证器的节点已被陈设到网络中，而以太坊2.0估量将有数千个节点。
以太坊基金会已经基于现有的不变客户端宣布了针对以太坊2.0的民众“进攻网”。
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.
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.
