The long-planned Ethereum fork is coming on Jan. 16th. With Constantinople going live within weeks, here’s what is important to know.
Constantinople is one of the key milestones in Ethereum’s roadmap to version 2.0, which moves the protocol from proof-of-work (PoW) to proof-of-stake (PoS). Compared to the larger plan, Constantinople’s changes are minor. The update introduces a few new opcodes—pieces of logic programmers use to develop smart contracts, delays the mining “difficulty bomb” and reduces the reward for finding blocks, and alters and optimizes the way gas is consumed.
