Hashing It Out #66 - Trueblocks - Thomas Jay Rush Nov 08, 2019

Show notes

The Ethereum ecosystem is very attractive to creators and data analysts, attracting tops engineers with its novel set of problems. Thomas Jay Rush, CEO of TrueBlocks.io is one such mind. He saw a problem with Ethereum's accounting and built a suite of tools to enable highly-details and lightning fast dives into the data of Ethereum, allowing users to find information about anything their address has touched. This is a far more compelling problem than most realize, and T.J. gives a great look into the design required to make such a service fast and responsive.
