Hashing It Out #35: Constantinople Postponement - Trail of Bits & ChainSecurity

ABOUT THIS EPISODE

Back with season 2 of Hashing It Out, and we have a doozy! This Episode features Trail of Bits and ChainSecurity to talk about their amazing last-minute catch of EIP-1283's impact on the Constantinople Ethereum hard fork. We go over how they found it, what recommendations they made, and how the hard fork was postponed to quickly. We also discuss the tooling behind analyzing such a vulnerability, the true impact had it been released, and how the processes around hard fork release candidates could be altered by this detection.

Hashing It Out #43 - Kadena - Stuart Popejoy and Emily Pillmore

We are excited to have the Kadena team back on with an update. The erudite Stuart Popejoy and brilliant Emily Pillmore speak more on Pact, the smart contract language with built-in formal verification used in the Kadena Chainweb. We learn more about formal verification: what it means, how it works, and a bit of its limitations. They also give us an update on Chainweb itself and talk us through some of the challenges since we last spoke... AND their innovated solutions to those challenges!
