The result is, as Buterin points out, that the vaunted attack resistance of proof-of-work blockchains like Bitcoin's is less than credible: As a result, the Bitcoin blockchain cannot process as many transactions per second as a traditional payment network such as PayPal or Visa. Nobody has discovered any way to greatly increase the computational scalability of the Bitcoin blockchain, for example its transaction throughput, and demonstrated that this improvement does not compromise Bitcoin's security. Given the objective 51% hashrate attack limit to some important security goals of public blockchains like Bitcoin and Ethereum, we actually do care about the distinguishable identity of the most powerful miners to answer the question "can somebody convince and coordinate the 51%? ./cache/blog-dshr-org-2064.html ./txt/blog-dshr-org-2064.txt
