| Data Availability | Data availability is exactly that - how available the data regarding transactions is to users. The data can be readily available on the blockchain (more expensive), or on a third-party data provider (cheaper, less “available”). |
| Validity Proofs | Verifiable cryptographic proofs that attest to the validity of off-chain transactions. |
| Layer-2 Rollups | Layer-2 (L2) refers to blockchain scaling solutions that handle transactions off Ethereum Layer-1 (L1), with settlement and data availability on L1. |
| Layer-3 Rollups | Layer-3 (L3) is to L2 what L2 is to L1. |
| ZK-Rollups | L2 smart contracts that verify transactions using cryptographic proofs computed on L2 and... |
