Citrea: Modular Rollup Framework on Bitcoin

Bitcoin’s lack of native programmability, coupled with advancements in zero knowledge cryptography, has led to rollups being explored as a substitute for an execution layer. Citrea’s approach involves using Bitcoin as a data availability & settlement layer for their zero knowledge rollup. These rollups not only lower transaction costs, but they also enable smart contracts to use Bitcoin’s L1 security and further incentivise miners to secure the chain despite halving rewards. In order to inherit Bitcoin’s security, zk proofs are inscribed in Bitcoin blocks.
