 ## ZK-Rollup
 
 A [rollup](/foundational-terms#rollup) that uses [ZKPs](#Zero-knowledge-proof-(ZKP)) (also often called [validity proofs](#Validity-proof) to [validate](#Validator) the correctness of the state transition function and update the rollup state. This is one of two main types of rollup constructions, along with [optimistic rollups](#Optimistic-rollup). In general, ZK-Rollups do not provide privacy preserving properties; privacy preserving ZK-Rollups are sometimes called ZK-ZK-Rollups.

+Protocols used to achieve agreement on a single data value among distributed processes or systems.
+
+## Merkle Trees
+
+Hierarchical structures that facilitate efficient verification of large data sets through cryptographic hashing.
+
+## Public Key Infrastructure (PKI)
+
+A system used to manage digital certificates and public-private key pairs, ensuring secure communication.
+
+## Immutable
+
+Refers to data or records on a blockchain that cannot be altered or tampered with once confirmed.
+
+## Oracles
+
+Third-party services that provide external data to smart contracts on a blockchain.
+
+## Fork
