Glossary

  • Fully Homomorphic Encryption (FHE): A cryptographic method that allows computation on encrypted data without decryption.

  • fhEVM: Fully Homomorphic Encryption Ethereum Virtual Machine, enabling encrypted data types and operations.

  • Layer 3 Blockchain: A blockchain that sits atop Ethereum (Layer 1) and Arbitrum (Layer 2) to provide specialized functionalities.

  • Arbitrum Nitro: A high-performance rollup solution for scaling Ethereum transactions.

  • Arbitrum Orbit: A framework for deploying custom Layer 3 chains.

  • Anytrust: A data availability model that optimizes rollup performance by reducing reliance on Layer 1 bandwidth.

  • RPC URL: Remote Procedure Call endpoint for connecting to the blockchain network.

  • Gateway URL: A service endpoint for decryption and re-encryption requests in encrypted smart contracts.

  • ACL (Access Control List): A security mechanism to define access permissions for encrypted data.

  • Ciphertext: Data encrypted using cryptographic techniques, unreadable without decryption.
