KAGOME – the C++ implementation of Polkadot Host milestone 2
KAGOME is a C++ implementation of the Polkadot Host that is protocol compatible with the original implementation in Rust and can already be used to run Relay chain validators and syncing nodes. With KAGOME and other client implementations we bring client diversity to Polkadot, mitigating risks of fatal bugs in a single client implementation, bringing innovations and broadening the development community. You may watch the most recent presentation during Polkadot Decoded 2023 to learn more about KAGOME.
During previous work as part of Kusama treasury grant, the following results were achieved:
- Parachains protocol integration
- Light clients compatibility
- Support for fast and warp synchronizations
- Multithreading execution
In addition to features that were planned during the previous proposal our team achieved the following:
- First non-Substrate Live validator on Westend network
- Zombienet support
- Improved performance of Erasure coding library
- KAGOME joined Thousand Kusama validators programme
The goals of this proposal are to prepare KAGOME for the upcoming features of Polkadot, such as asynchronous backing, SASSAFRAS, BEEFY, and so on. We also plan to further improve KAGOME by improving RPC and WASM performance. Additionally, we plan to conduct an external security audit to build confidence in KAGOME among node operators. To achieve all of this, the work on the new proposal scope will be a joint effort between Quadrivium, Soramitsu, and SRLabs:
- Quadrivium is a team of original C++ developers that developed KAGOME and C++ Libp2p. In August 2023 entire team has spun off from Soramitsu to group Quadrivium that will be responsible for feature implementation.
- During this grant proposal implementation Soramitsu partners with Quadrivium to provide DevOps, QA and Security services for KAGOME. Soramitsu team is also experienced with KAGOME and Substrate and has necessary expertise to provide necessary infrastructure for testing KAGOME to ensure its stability, conformance with the spec and compatibility with Substrate
- SRLabs is a Security Audit company that will be conducting an initial audit of KAGOME. SRLabs already has years of experience in auditing Substrate, which makes it a perfect fit for checking KAGOME
In addition, Web3 Foundation will be participating as technical advisor and will provide mentoring and technical support to ensure the completeness of milestones and conforming the specification.
The scope of this proposal:
- Optimized Merkle storage
- RPC Improvements: caching, new interfaces
- Asynchronous backing
- Libp2p improvements: QUIC, WebRTC, DOS protection
- SASSAFRAS
- BEEFY
- New WASM Engine (WASM Edge)
- General maintenance
- Development infrastructure
- Integration tests with Zombienet
- Security Audit

- KAGOME is a computer program written in C++ that works with Polkadot, allowing it to run efficiently.
- It helps make sure there are different versions of the program to avoid problems if one has bugs.
- The team has added new features like showing quick information and making programs run faster.
- KAGOME became the first live validator on the Westend network.
- The team plans to improve KAGOME with better speed, safety checks, and more features.
- Three groups, Quadrivium, Soramitsu, and SRLabs, are working together to make KAGOME better.
- They need financial help for their plans, asking for a certain amount of money called DOT.
