Welcome to the official GitHub repository for the SRI - Stratum V2 Reference Implementation.

Stratum V2 is a next-generation bitcoin mining protocol designed to enhance the efficiency, security, flexibility and decentralization. SRI is fully open-source, community-developed, independent of any single entity, aiming to be fully compatible with Stratum V2 Specification.

To get started with the Stratum V2 Reference Implementation (SRI), please follow the detailed setup instructions available on the official website:

Getting Started with Stratum V2

This guide provides all the necessary information on prerequisites, installation, and configuration to help you begin using, testing or contributing to SRI.

The library is modular to address different use-cases and desired functionality. Examples include:

• SV1 Miners can use the translator proxy (roles/translator) to connect with a SV2-compatible pool.
• SV1 mining farms mining to a SV2-compatible pool gain some of the security and efficiency improvements SV2 offers over Stratum V1 (SV1). The SV1<->SV2 translator proxy does not support all the features of SV2, but works as a temporary measure before upgrading completely to SV2-compatible firmware. (The SV1<->SV2 translation proxy implementation is a work in progress.)

• Pools supporting SV2 can deploy the open source binary crate (roles/pool) to offer their clients (miners participating in said pool) an SV2-compatible pool.
• The Rust helper library provides a suite of tools for mining pools to build custom SV2 compatible pool implementations.
• The C library provides a set of FFI bindings to the Rust helper library for miners to integrate SV2 into their existing firmware stack.

Our roadmap is publicly available, outlining current and future plans. Decisions on the roadmap are made through a consensus-driven approach, through participation on dev meetings, Discord or GitHub.

The goals of this project are to provide:

1. A robust set of Stratum V2 (SV2) primitives as Rust library crates which anyone can use to expand the protocol or implement a role. For example:
   • Pools supporting SV2
   • Mining-device/hashrate producers integrating SV2 into their firmware
   • Bitcoin nodes implementing Template Provider to build the blocktemplate
2. The above Rust primitives as a C library available for use in other languages via FFI.
3. A set of helpers built on top of the above primitives and the external Bitcoin-related Rust crates for anyone to implement the SV2 roles.
4. An open-source implementation of a SV2 proxy for miners.
5. An open-source implementation of a SV2 pool for mining pool operators.
