Featured hacks
OP Stack Hacks are explicitly things that you can do with the OP Stack that are not currently intended for production use.
OP Stack Hacks are not for the faint of heart. You will not be able to receive significant developer support for OP Stack Hacks — be prepared to get your hands dirty and to work without support.
Overview
Featured Hacks is a compilation of some of the cool stuff people are building on top of the OP Stack!

Ticking Optimism

Description
Ticking Optimism is a proof-of-concept implementation of an OP Stack chain that calls a tick function every block. By using the OP Stack, Ticking Optimism avoids the need for off-chain infrastructure to execute a function on a regular basis. Ticking Conway is a system that uses Ticking Optimism to build Conway's Game of Life (opens in a new tab) onchain.
OP Stack configuration
- Data Availability: Ethereum DA (any)
- Sequencer: Single Sequencer
- Derivation: Standard Rollup with custom
