What block size for Ethereum&#x27;s blockchain would be required to hit 56,000 tps? I&#x27;m really getting some deja vu in having to write this out for the millionth time in a 18 month period.<p>None of your talking points magically address the extreme costs of prerequisite physical infrastructure needed to hit 56,000 tps.<p>Bottom line, it&#x27;s impossible to match the throughput capacity of just a single credit card company on <i>any blockchain</i>, be it Bitcoin or Ethereum or BBQCoin, without incurring enormous costs in terms of CPU and bandwidth. This is to say nothing of doing decentralized exchanges, order matching, and option contracts - all of which Ethereum has been advertised as doing on a blockchain. For that you&#x27;d need <i>hundreds of thousands</i> of tps.
