ETH 与 BETH 之间的纠葛 ｜ 以太坊2.0漫谈

Eth2.0 协调员 Danny Ryan 表示这种单向桥接的方式更像是一种策略决定，而并不是因为在技术上无法实现。

Eth2.0 > Coordinator Danny Ryan said that this one-way bridge approach was more a strategic decision than a technical impossibility.

Danny 表示如果允许 PoS 代币转回成 PoW 代币，这将减缓整个 Eth2.0 的开发进程，且在技术上“需要将信标链的状态暴露于1.0链中，并在1.0和2.0链上增加额外的共识规则来处理1.0链上的代币重铸和2.0链上的代币销毁。”

Danny indicates that if Pos is allowed to convert into Pow, this will slow down the development of Eth 2.0 as a whole and that there is a technical “need to expose the beacon chain to the 1.0 chain and to add additional consensus rules to the 1.0 and 2.0 chain to deal with the recasting and destruction of the coins on the 1.0 chain. ”

也就是说，如果想要将信标链中的 PoS 代币转回成 Eth1.0 链中的 PoW 代币，那转回的方式就会像用户通过抵押合约将 PoW 币转换成 PoS 币一样，只是方向相反。如果实现了这种双线桥接，那以太坊的 PoW 代币和 PoS 代币就别无二致了。

means that if you want to convert the PS in the beacon chain back into the PW in the Eth1.0 chain, it'll be the same way that the user converts the Pow currency into the PS through a mortgage contract, but in the opposite direction. If this two-line bridge is reached, the PW and PS in the Taipan will be the same as

目前尚不清楚以太坊是否会在将来实现 PoS 代币转回成 PoW 代币，很多相关的讨论在变化中。此前以太坊研究员 Justin Drake 预计可能在2020年底将实现 Eth1.0 链和 Eth2.0 链之间的“通信”(通过改变 Eth1.0 链的分叉选择规则，并对其进行分叉)，但 Joseph Lubin 在最近的 DevCon5 会议期间表示 Eth2.0 的阶段1和阶段2将可能于2020年底合并推出。

it is not clear whether the Etheria will be returning PPS in the future to Pow, and many related discussions are changing . > > >

因此，具体情况仍不清楚，但交易所有可以选择。

上架 BETH 代币？

/strang'

就作者了解的情况而言，由于当信标链启动之后，验证者似乎可以将 BETH 发送给其他的验证者，因此交易所将可以选择上架信标链上的 BETH 代币资产。

目前尚不清楚这些 BETH 代币是否可以发送给仅仅拥有信标链账户的非验证者用户，或者一开始在信标链上是否会存在非验证者的账户。

It is not clear whether these BETH tokens can be sent to non-certifier users who only own the beacon chain accounts, or whether there will initially be a non-certifier account on the beacon chain.

这是因为，信标链只是作为「协调者」的身份来协调验证者 (及其抵押的代币) 应该验证哪条分片链。但起初 Eth2.0 系统中并不存在分片链，因此也就不存在需要在不同的分片链之间转移 BETH 代币了，信标链一开始只是一条笨拙的区块链。

在实现分片链之前，交易所为何需要上架这种 BETH 代币，目前尚不清楚。但显然有些用户在成为信标链的验证者之后，可能不想要继续抵押自己的代币资产，因此想要将自己的 BETH 代币转给其他人，这个接收者可能之前并没有或者不想要通过往抵押合约中发送 ETH 代币来成为信标链验证者。

It is not clear why the exchange needed to mount such BETH tokens before it could achieve a segmental chain. , however, it is clear that some users may not want to continue to encumber their token assets after becoming the certifier of the beacon chain and therefore want to transfer their BETH tokens to others, who may not have been or do not want to be the certifier of the beacon chain by sending the ETH in the collateral contract.

另外，你可能认为交易所将必须上架两种不同的以太坊代币，因为显然 ETH 和 BETH 是两种不同的代币，因为当前的 ETH 已经获得了大量用户的使用和诸多 DeFi 应用的支持，而 BETH 则仅仅是用于 staking 而已。

Also, you may think that the exchange will have to go up to two different Ethio tokens, because it is clear that ETH and BETH are two different tokens, because the current ETH has been supported by a large number of users and many DeFi applications, while BETH is only used to stay.

如果交易所一直等到分片链结构实现之后再上架 BETH 代币，那么可以说，届时它们依然会是两种不同的代币，因为 ETH 是一种 PoW 代币，而 BETH 是一种 PoS 代币。

If the exchange waits until the segmental chain structure is realized before the BETH tokens are on board, then it can be said that they will still be two different tokens at that time, because the ETH is a Pow token, while the BETH is a PS token.

这两种代币之间将在多大程度上有所不同，这将取决于相关的钱包是如何实现的，以及相关的地址是怎样的。

The extent to which the two tokens will differ will depend on how the related wallet is realized and what the relevant address is.
