Off-Chain Computation
Also known as: External Computation, Off-Chain Processing, Verifiable Computation
A method where heavy or complex calculations are executed outside the blockchain to enhance scalability and efficiency.
Off-chain computation refers to the process of performing data processing or complex logic outside the main blockchain network. Instead of executing heavy computations on-chain, which can be expensive and slow, off-chain systems handle the work and then submit verifiable results to the blockchain. This approach preserves decentralization and security while improving performance. It’s used in rollups, zero-knowledge proofs, oracles, and data aggregators. Tools like Chainlink, StarkWare, and zkSync leverage off-chain computation for price feeds, proof generation, and privacy-preserving transactions.
