# Protocol Customizations

GETH code for Vanar chain

Vanar chain's adaptation of the [Ethereum GETH](https://geth.ethereum.org/) (Go-Ethereum) codebase is driven by precise business objectives, primarily centered around accelerating transaction confirmations and reducing transaction costs. Here, we provide a comprehensive breakdown of the pivotal alterations applied to the GETH codebase to align seamlessly with Vanar's strategic goals
