FireFly](./images/hyperledger_firefly_logo.png)\n\nHyperledger FireFly is the first open source Supernode: a complete stack for enterprises to build and scale secure Web3 applications.\n\nThe FireFly API for digital assets, data flows, and blockchain transactions makes it radically faster to build production-ready apps on popular chains and protocols.\n\n[ENGLISH](./README.md) | [简体中文](./README_zh_CN.md)\n\n## Start using Hyperledger FireFly\n\nThe best place to learn about FireFly is in the [documentation](https://hyperledger.github.io/firefly).\n\nThere you will find our [Getting Started Guide](https://hyperledger.github.io/firefly/latest/gettingstarted/),\nwhich will get you a running FireFly network of Supernodes on your local machine in a few minutes.\n\nYour development environment will come with:\n\nFireFly CLI                   |  FireFly Explorer UI                | FireFly Sandbox  |\n:----------------------------:|:-----------------------------------:|:----------------:|\n[![CLI](./images/firefly_cli.png)](https://hyperledger.github.io/firefly/latest/gettingstarted/firefly_cli/#install-the-firefly-cli) | [![UI](./images/firefly_explorer.png)](https://github.com/hyperledger/firefly-ui) | [![Sandbox](./images/firefly_sandbox.png)](https://hyperledger.github.io/firefly/latest/gettingstarted/sandbox/#use-the-sandbox) |\n\n## Engage with the community\n\n- [Join us on Discord](https://discord.gg/hyperledger)\n\n## Technical architecture\n\nHyperledger FireFly has a pluggable microservices architecture. Everything is pluggable, from the Blockchain technology,\ntoken ERC standards, and custom smart contracts, all the way to the event distribution layer and private database.\n\nSo if there aren't yet instructions for making FireFly a Supernode for your favorite blockchain technology -\ndon't worry. There is almost certainly a straightforward path to plugging it in that will save you from re-building\nall the plumbing for your blockchain application from scratch.\n\n[![Hyperledger FireFly Architecture Overview](./doc-site/docs/images/firefly_architecture_overview.jpg)](https://raw.githubusercontent.com/kaleido-io/firefly/main/doc-site/docs/images/firefly_architecture_overview.jpg)\n\n## Start contributing to Hyperledger FireFly\n\nThere are lots of places you can contribute, regardless of whether your skills are front-end, backend-end, or full-stack.\n\nCheck out our [Contributor Guide](https://hyperledger.github.io/firefly/latest/contributors/), and **welcome!**.\n\n## Other repos\n\nYou are currently in the \"core\" repository, which is written in Go and hosts the API Server and central orchestration\nengine. Here you will find plugin interfaces to microservice connectors written in a variety of languages like\nTypeScript and Java, as well as heavy-lifting runtime components.\n\nOther repositories you might be interested in containing those microservice components, user experiences, CLIs and samples.\n\n\u003e Note that only open source repositories and plugins are listed below\n\n### Blockchain connectivity\n\n- Transaction Manager - \u003chttps://github.com/hyperledger/firefly-transaction-manager\u003e\n- RLP \u0026 ABI encoding, KeystoreV3 utilities and secp256k1 signer runtime -  \u003chttps://github.com/hyperledger/firefly-signer\u003e\n- FFCAPI reference connector for EVM Chains - \u003chttps://github.com/hyperledger/firefly-evmconnect\u003e\n  - Public EVM compatible chains: Learn more in the [documentation](https://hyperledger.github.io/firefly)\n- Permissioned Ethereum connector - \u003chttps://github.com/hyperledger/firefly-ethconnect\u003e\n  - Private/permissioned: Hyperledger Besu / Quorum\n- Hyperledger Fabric connector - \u003chttps://github.com/hyperledger/firefly-fabconnect\u003e\n- Tezos connector - \u003chttps://github.com/hyperledger/firefly-tezosconnect\u003e\n- Cardano connector - \u003chttps://github.com/hyperledger/firefly-cardano\u003e\n- Corda connector starter: \u003chttps://github.com/hyperledger/firefly-cordaconnect\u003e\n  - CorDapp specific customization is required\n\n### Token standards\n\n- Tokens ERC20/ERC721 - \u003chttps://github.com/hyperledger/firefly-tokens-erc20-erc721\u003e\n- Tokens ERC1155 - \u003chttps://github.com/hyperledger/firefly-tokens-erc1155\u003e\n\n### Private data bus connectivity\n\n- HTTPS Data Exchange - \u003chttps://github.com/hyperledger/firefly-dataexchange-https\u003e\n\n### Developer ecosystem\n\n- Command Line Interface (CLI) - \u003chttps://github.com/hyperledger/firefly-cli\u003e\n- Explorer UI - \u003chttps://github.com/hyperledger/firefly-ui\u003e\n- Node.js SDK - \u003chttps://github.com/hyperledger/firefly-sdk-nodejs\u003e\n- Sandbox / Exerciser - \u003chttps://github.com/hyperledger/firefly-sandbox\u003e\n- Samples - \u003chttps://github.com/hyperledger/firefly-samples\u003e\n- FireFly Performance CLI: \u003chttps://github.com/hyperledger/firefly-perf-cli\u003e\n- Helm Charts for Deploying to Kubernetes: \u003chttps://github.com/hyperledger/firefly-helm-charts\u003e\n\n## FireFly Core code hierarchy\n\n```\n┌──────────┐  ┌───────────────┐\n│ cmd      ├──┤ firefly   [Ff]│  - CLI entry point\n└──────────┘  │               │  - Creates parent context\n              │               │  - Signal handling\n              └─────┬─────────┘\n                    │\n┌──────────┐  ┌─────┴─────────┐  - HTTP listener (Gorilla mux)\n│ internal ├──┤ api       [As]│    * TLS (SSL), CORS configuration etc.\n└──────────┘  │ server        │    * WS upgrade on same port\n              │               │  - REST route definitions\n              └─────┬─────────┘    * Simple routing logic only, all processing deferred to orchestrator\n                    │\n              ┌─────┴─────────┐  - REST route definition framework\n              │ openapi   [Oa]│    * Standardizes Body, Path, Query, Filter semantics\n              │ spec          |      - OpenAPI 3.0 (Swagger) generation\n              └─────┬─────────┘    * Including Swagger.
