Hooks

In the context of blockchain, ‘hooks’ typically refer to pieces of code that allow developers to customise the behaviour of a blockchain protocol. These hooks are often used on smart contract platforms or in blockchain frameworks that support programmable functionality.

Hooks enable developers to inject their custom logic at specific points within the blockchain’s execution process, empowering developers to create decentralised applications (dapps) with complex functionalities.

For example, in Ethereum, hooks can be implemented using Solidity programming language in the form of modifiers or event listeners. Modifiers can be attached to functions to enforce certain conditions before execution, while event listeners can trigger actions based on specific events occurring on the blockchain.
