# Kickstart The next-generation Layer 2 scaling solution for Bitcoin. This guide will walk you through the essential steps to start building, interacting, or contributing to the IBVM ecosytem The IBVM is a fully Ethereum Virtual Machine (EVM) equivalent VM running on Bitcoin and using BTC as its native token. EVMs as a concept are the most battle-tested and mature VM in the cryptocurrency ecosystem. It is a deterministic, stack-based virtual machine, renowned for its ability to efficiently execute smart contracts in a secure and isolated environment. IBVM implements its own EVM, referred to as a "zkEVM". A zkEVM is a special EVM implementation that makes the full VM implementation provable. Citrea zkEVM is classified as Type 2, which means full equivalency and a scalable and trustless proof system due to being based on zk-STARKs. IBVM zkEVM is built using RISC Zero. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://ibvm.gitbook.io/ibvm-doc/developer-documentation/kickstart.md?ask= ``` The question should be specific, self-contained, and written in natural language.
