# Proof Data Availability ⎊ Area ⎊ Greeks.live --- ## What is the Availability of Proof Data Availability? Proof Data Availability is the guarantee that the data required to verify a cryptographic proof, particularly in the context of Layer 2 scaling solutions like rollups, is accessible to all relevant parties. This means the underlying transaction data for a rollup block must be published to the Layer 1 blockchain or a highly available data layer. Without this availability, the security model of rollups breaks down, as fraud or incorrect state transitions cannot be proven. ## What is the Security of Proof Data Availability? The security of optimistic and zero-knowledge rollups fundamentally relies on proof data availability. If the data is not available, honest participants cannot reconstruct the rollup state or generate fraud proofs, potentially allowing malicious operators to commit invalid state transitions. This principle ensures that the Layer 1 chain can always act as the ultimate arbiter, even if the Layer 2 operator attempts to censor or hide data. It is a critical component of trust minimization. ## What is the Verification of Proof Data Availability? Proof data availability directly enables the verification process. For optimistic rollups, it allows anyone to challenge an invalid state transition by reconstructing the transaction history and submitting a fraud proof. For ZK-rollups, it ensures that the inputs used to generate the zero-knowledge proof are publicly accessible, allowing for full transparency and auditability. This public verifiability is essential for maintaining the integrity and decentralization of Layer 2 systems. --- ## [Proof Verification Bottlenecks](https://term.greeks.live/definition/proof-verification-bottlenecks/) Points of congestion where verification of proofs cannot keep pace with generation, causing settlement delays. ⎊ Definition ##
