This capabilities would be basically a way of de-centralized data analytics and I wonder if and how this can be done in Ethereum?contract-development contract-invocation up vote 1 down vote I'm not sure if I understand but it doesn't seem to be making sense.Ethereum is not a parallel computing platform.It doesn't make computation go faster (the way a supercomputer does).bitcoin header formatWhat it does is that it makes computation 'safer' because each node runs the same thing and verifies that they all get the same result.bitcoin mixing service deutschSo if I were you, I'd go the standard approach of data analytics - download the data from ethereum chain and then boot up as many servers as you think you need to crunch the numbers.bitcoin etf 30 march
