<div><p>To build the project I mentioned in <a href="https://ethresear.ch/t/generating-eddsa-pasta-keypairs/22610" rel="nofollow">this topic</a> I started learning about zk-SNARKs. One of the things I seem to understand is that the ECDSA signature scheme and the SHA-3 hash (formerly known as Keccak) don’t play well with zk-SNARKs because they result in massive circuits. IIUC, EdDSA with certain curves and the Poseidon hash fare much better in that regard, with circuits that could be hundreds of times smaller.</p><p>Hashing and verifying signatures are very common use cases in Solidity smartcontracts, but Solidity uses SHA-3 for hashes and AFAIK all Ethereum wallets are based on ECDSA. <strong>Does that mean that all Solidity smartcontracts are inherently hard to prove in zk-SNARKs?</strong> If so, how did Polygon zkEVM solve that problem? What zk-SNARK scheme does it use (Groth16 / PLONK / PLONKish / Halo2 / other) ?</p><div><br></div></div>

Does Ethereum have a zk-verifiability problem?

<div><p>为了构建我在<a href="https://ethresear.ch/t/generating-eddsa-pasta-keypairs/22610" rel="nofollow">这个主题</a>中提到的项目，我开始学习零知识证明。我似乎理解的是，ECDSA签名方案和SHA-3哈希（以前称为Keccak）在零知识证明中表现不佳，因为它们会导致巨大的电路。据我所知，使用特定曲线的EdDSA和Poseidon哈希在这方面要好得多，其电路可能小几百倍。</p><p>哈希和验证签名是Solidity智能合约中非常常见的用例，但Solidity使用SHA-3进行哈希，据我所知，所有以太坊钱包都基于ECDSA。<strong>这是否意味着所有Solidity智能合约在零知识证明中本质上很难证明？</strong>如果是这样，Polygon zkEVM是如何解决这个问题的？它使用什么样的零知识证明方案（Groth16 / PLONK / PLONKish / Halo2 / 其他）？</p><div><br></div></div>

以太坊是否存在 zk 可验证性问题？

比特币即将选择方向？

我们今天看到黄金、白银、钯金同步创下新高！目前黄金自从 10 月底修正以来，踩在三日线的 25~35 均线带上面；白银则是沿着四小时均线上涨；钯金沿着三日线均线上涨。
同步性： 这种“同步新高”通常意味着大级别的趋势启动。黄金提供“稳定性”，白银提供“弹性”，而钯金的加入则意味着工业与投资需求的双重爆发。
在这样明显的上涨趋势中，量能并未明显减弱且未出现任何空头结构。不要想着摸顶做空，否则会变成“...
