论文摘要
在2020年，Sala，Sogiorno和Taufer能够找到一些比特币地址的私钥，因此能够花费与它们相关的加密货币。该结果是出乎意料的，因为对区块链地址的非平凡私钥的恢复被认为是一个不可行的问题。在本文中，我们通过与私钥集的其他小子集进行类似的攻击来扩大分析。然后，我们还将其应用于其他区块链，检查以太坊，Dogecoin，Litecoin，Dash，Zcash和Bitcoin Cash。除结果外，我们还解释了我们用来对这些区块链中出现的所有地址进行详尽搜索的技术。
In 2020 Sala, Sogiorno and Taufer have been able to find the private keys of some Bitcoin addresses, thus being able to spend the cryptocurrency linked to them. This result was unexpected, since the recovery of non-trivial private keys for blockchain addresses is deemed to be an infeasible problem. In this paper we widen this analysis by mounting a similar attack to other small subsets of the set of private keys. We then apply it to other blockchains as well, examining Ethereum, Dogecoin, Litecoin, Dash, Zcash and Bitcoin Cash. In addition to the results, we also explain the techniques we have used to perform this exhaustive search for all the addresses that have ever appeared in these blockchains.
