Do not expect this to run. Do not run this in production.\n\n\u003e [!IMPORTANT]\n\u003e Kora uses BLS12-381 threshold consensus via [commonware](https://github.com/commonwarexyz/monorepo), [REVM](https://github.com/bluealloy/revm) for EVM execution, and [QMDB](https://github.com/commonwarexyz/monorepo/tree/main/storage) for state storage.\n\n## What's Kora?\n\nKora is a minimal, high-performance execution client built entirely in Rust. It combines commonware's BLS12-381 threshold consensus with REVM for EVM execution and QMDB for efficient state storage. The architecture is modular with distinct layers for consensus (BLS12-381 threshold signatures via commonware simplex), execution (EVM state transitions powered by REVM), storage (high-performance state management with QMDB), and networking (P2P transport and message marshaling).\n\n## Why?\n\nExisting options for building EVM-compatible nodes on commonware are limited. The [tempo node](https://github.com/commonwarexyz/monorepo/tree/main/examples/tempo) uses reth, which is heavy and comes with opinionated Ethereum traits and abstractions that may not suit all use cases. The [revm commonware example](https://github.com/commonwarexyz/monorepo/pull/2495) is limited to a mock simulation without real networking or persistence. There isn't a public, lightweight node available that connects revm directly to commonware with full consensus and storage. Kora fills this gap by providing a minimal, production-oriented node that integrates revm with commonware simplex consensus and QMDB storage.\n\n## Usage\n\nStart the devnet with interactive DKG (Distributed Key Generation):\n\n```sh\njust devnet\n```\n\n\u003e [!TIP]\n\u003e See the [Justfile](./Justfile) for other useful commands.\n\n## Demo\n\nhttps://github.com/user-attachments/assets/8ea05477-039d-4dd2-a7f3-660f179299f7\n\n## Architecture\n\nThe devnet runs in three phases. Phase 0 generates ed25519 identity keys for each validator node. Phase 1 is the DKG ceremony, an interactive threshold key generation process using Ed25519 simplex consensus where validators collaborate to generate a shared BLS12-381 threshold key. Phase 2 launches full validator nodes running BLS12-381 threshold consensus, the REVM execution engine, and QMDB state storage.\n\nObservability is provided through Prometheus metrics with Grafana dashboards for monitoring node health, consensus performance, and execution metrics.\n\n## Contributing\n\nContributions are welcome!
