Smart Contract

Self-executing programs stored on a blockchain that automatically enforce the terms of an agreement when conditions are met.

Decentralised Autonomous Organisation

An organisation governed by smart contracts and token holder votes rather than centralised management.

Solidity

A programming language designed for writing smart contracts on the Ethereum Virtual Machine.

Oracle

A service that provides external real-world data to blockchain smart contracts that cannot access off-chain information directly.

Chainlink

A decentralised oracle network that connects smart contracts with external data sources, APIs, and payment systems.

Account Abstraction

A blockchain architecture improvement that allows smart contracts to act as user accounts, enabling features like social recovery, gas sponsorship, and batched transactions.

Programmable Money

Digital currency embedded with executable logic that can enforce spending conditions, automate payments, and integrate with smart contracts for conditional financial operations.

Blockchain Oracle

Digital Bond

A fixed-income security issued and managed on blockchain infrastructure, automating coupon payments, settlement, and transfer of ownership through smart contracts.

A blockchain network where participation is restricted to authorised entities, common in enterprise applications.

An uncollateralised loan in DeFi that must be borrowed and repaid within a single blockchain transaction.

The ability of a distributed system to reach consensus despite some nodes acting maliciously or failing.

A blockchain-based token that provides access to a specific product, service, or platform functionality, rather than representing ownership or investment rights.

The property of blockchain data that prevents alteration or deletion once recorded on the ledger.

A mathematical function that converts input data of any size into a fixed-size output, used extensively in blockchain security.

The vision of a decentralised internet built on blockchain technology, giving users ownership and control of their data.

A DeFi strategy where users provide liquidity to protocols in exchange for token rewards and interest.
