Citrea - Series A

Citrea is the first rollup that enhances the capabilities of Bitcoin blockspace with zero-knowledge technology, making it possible to build everything on Bitcoin. This requires no changes to the network's consensus rules. Citrea processes a large number of zkEVM transaction batches and submits a succinct zero-knowledge proof that allows easy verification of the batch validity in an inscription-like envelope to Bitcoin. The zero-knowledge proofs generated by the prover outputs the state difference that batch resulted in, with these proofs then being published to Bitcoin regularly.
