Preethi does a great job of bringing some sanity to the (somewhat justified) hype around Ethereum and friends:

blockchains have several major technical barriers that make them impractical for mainstream use today… it could be many years before trustless systems are ready for mainstream use at scale.

We discussed these issues with Preethi in-depth at the tail end of The Changelog #277.

Preethi Kasireddy, a self-employed blockchain and smart contract Engineer, joined the show to talk about why she left the best job in the world at Andreessen Horowitz on the deal team, how she got entrepreneurship envy, the roadmap she laid out in 2015 and where she’s at today as an engineer, her excitement for blockchain-based technologies, and why blockchains don’t scale.
