zk-Rollup

Zero-Knowledge Proof

A cryptographic method allowing one party to prove knowledge of information without revealing the information itself.

zk-SNARK

Zero-Knowledge Succinct Non-Interactive Argument of Knowledge — a compact zero-knowledge proof requiring no interaction between prover and verifier.

Decentralised Identity

A self-sovereign identity framework where individuals control their own digital identity credentials without centralised authorities.

Soulbound Token

A non-transferable digital token permanently associated with an individual's blockchain address, used to represent credentials, affiliations, and reputation in a verifiable manner.

A decentralised decision-making process where protocol changes are proposed, debated, and voted on through blockchain-based mechanisms by token holders or validators.

A cryptographic mechanism that verifies the authenticity and integrity of digital messages or documents.

Software or hardware that stores cryptographic keys and enables users to manage their blockchain assets.

A backward-compatible upgrade to a blockchain protocol where old nodes still recognise new blocks as valid.

A Layer 2 scaling solution that executes transactions off-chain and posts compressed transaction data to the main chain.

A cryptocurrency wallet connected to the internet for convenient but less secure asset management.
