Optimism Introduces Modular Components OP Stack

Ethereum Layer2 solution Optimism introduced the OP Stack, a set of modular components that can be assembled to build custom chains to fit any use-case. It's a series of modules that work together to form coherent, reliable blockchains. Optimism said that via shared sequencing and messaging layers, the boundaries between the op-chains of the future may dissolve, resulting in a logical chain "Superchain".
