The official specifications repository for the Fuel protocol and FuelVM, a fast verifiable blockchain virtual machine. It is a documentation project built with mdbook covering transaction formats, validity rules, cryptographic primitives, ABI, and the FuelVM instruction set.
Use cases
- understand the FuelVM instruction set
- implement a Fuel transaction parser
- learn Fuel transaction validity rules
- build a tool that computes Fuel transaction or contract IDs
- implement the Fuel block header format
- verify Sparse Merkle Tree correctness against the spec test suite
- understand Fuel consensus parameters and gas costs
When to choose
- you are implementing a Fuel client, VM, or toolchain and need normative protocol details
- you want to build tooling that parses or validates Fuel transactions
- you need authoritative reference material on the FuelVM architecture
When to avoid
- you want runnable code or SDKs rather than specifications
- you are looking for a general-purpose blockchain tutorial rather than Fuel-specific protocol docs
- you need end-user documentation for Fuel wallets or apps
