为了使每个人都能验证签名,必须使用reveal operations将公钥存储在区块链上.据我了解,以太坊不需要这种操作,可以从签名中检索它们.使用额外操作的优点是什么?

In order for everybody to be able to validate signatures, public keys have to be stored on the blockchain using reveal operations. As far as I understand, such operations are not needed in Ethereum, where they can be retrieved from the signatures. What are the pros of using an extra operation?

以太坊检索公共密钥的方法仅适用于某些签名算法,在这种情况下为ECDSA和secp256k1.Tezos也将它用于tz2(和P-256用于tz3),但不用于使用EdDSA的tz1.通常,Tezos希望将来支持新的签名算法.从这个角度来看,Reveal更通用,并且可以与将来的所有更改一起使用.

Ethereum way of retrieving the public key only works with some signing algorithms, ECDSA with secp256k1 in its case. It is also used by Tezos for tz2 (and P-256 for tz3), but not for tz1 which uses EdDSA. In general, Tezos wants to support new signature algorithms in the future. From this point of view, Reveal is more general and will work with probably all future changes.

- 特定曲线不是允许的曲线,而是ECDSA签名算法.对于tz2和tz3地址,Tezos在曲线secp256k1和p-256上使用ECDSA算法.但是,tz1地址使用EdDSA,它基于Scnhnorr签名,并且不允许从签名中恢复公钥.但是,此签名方案还有其他好处,尽管在Tezos中尚未使用.
  
  The specific curve isn't what permits this, it's the ECDSA signing algorithm. For tz2 and tz3 addresses, Tezos uses the ECDSA algorithm on curves secp256k1 and p-256. However, tz1 addresses use EdDSA, which is based on Scnhnorr signatures and doesn't allow recovery of the public key from the signature. There are however other benefits to this signing scheme, though they aren't used yet in Tezos.
