Citrea’s Fee Mechanism: Bitcoin Security at Scale
Citrea’s Fee Mechanism: Bitcoin Security at Scale Citrea’s core value proposition is to enable greater expressivity and increase the utility of Bitcoin blockspace without ever leaving Bitcoin. To achieve this, Citrea keeps data availability and verifiability on-chain, on Bitcoin. Consequently, Citrea inscribes its state changes to Bitcoin and generates a zero-knowledge proof that asserts the validity of those changes. However, inscribing every state change, i.e. transaction, to Bitcoin is not feasible due to high transaction costs and Bitcoin's limited blockspace. Instead, Citrea inscribes the state differences, storage slot differences between the initial and latest state of the given batch, to Bitcoin.
