A minimal implementation of custom virtual machine (VM) for Avalanche subnet.

This project implements timestampvm that allows anyone to propose and read blocks, each of which is tagged with the proposed timestamp. It implements the snowman block.ChainVM interface in Rust, pluggable to AvalancheGo nodes. See https://github.com/ava-labs/timestampvm for the original Go implementation.

Layout

The project is structured such that it can be used as a template to build more complex VMs (e.g., Ethereum VM, key-value store VM).

The major components are:

• api: Implementation of timestampvm APIs.

• bin/timestampvm: Command-line interface, and plugin server.

• block: Implementation of snowman.Block interface for timestampvm.

• genesis: Defines timestampvm genesis block.

• state: Manages the virtual machine states.

• vm: Implementation of snowman block.ChainVM interface for timestampvm.
