The source is based on the [wasmd](https://github.com/CosmWasm/wasmd) variant of the Cosmos-SDK, which includes a virtual machine that compiles to WebAssembly. It contains Fetch.ai-specific updates required for the test networks and future mainnet, including a decentralized random beacon (DRB) and a novel, compact multi-signatures scheme. Versions of this repository are not currently synchronised with either wasmd or the Cosmos-SDK. Please refer to the [releases](https://github.com/fetchai/fetchd/releases) section for the compatibility with upstream versions.\n\n**Note**: Requires [Go 1.18+](https://golang.org/dl/)\n\n## Supported Systems\n\nThe supported systems are limited by the dlls created in [`go-cosmwasm`](https://github.com/CosmWasm/go-cosmwasm). In particular, **we only support MacOS and Linux**.\n\n## Quick Start\n\n### Building and testing the project\n\nFirst, install golang \u003e= v1.18 (follow the guide from [https://golang.org/dl/](https://golang.org/dl/)) and execute the following commands:\n\n```bash\n# make sure you have the following packages:\napt-get update \u0026\u0026 apt-get install -y make gcc\n\n# install fetchd. This will output the binary in ~/go/bin/ folder by default.\nmake install\n```\n\nYou should now have `fetchd` successfully installed in your path. You can check this with the following command:\n\n```bash\nwhich fetchd\n```\n\nThis should return a path such as `~/go/bin/fetchd` (might be different depending on your actual go installation).\n\n\u003e If you get no output, or an error such as `which: no fetchd in ...`, possible cause can either be that `make install` failed with some errors or that your go binary folder (default: ~/go/bin) is not in your `PATH`.\n\u003e\n\u003e To add the ~/go/bin folder to your PATH, add this line at the end of your ~/.bashrc:\n\u003e\n\u003e```bash\n\u003eexport PATH=$PATH:~/go/bin\n\u003e```\n\u003e\n\u003eand reload it with:\n\u003e\n\u003e```bash\n\u003esource ~/.bashrc\n\u003e```\n\nYou can also verify that you are running the correct version\n\n```bash\nfetchd version\n```\n\nThis should print a version number that must be compatible with the network you're connecting to (see the [network page](https://docs.fetch.ai/ledger_v2/live-networks/) for the list of supported versions per network).\n\nAlternatively, you can also build without installing the binary with:\n\n```bash\nmake build\n```\n\nThe fetchd binary will be available under `./build/fetchd`.\n\n## Run a simple local test network\n\nThe easiest way to get started with a simple network is to run the [docker-compose](https://docs.docker.com/compose/). The details of this can be found [here](https://github.com/fetchai/fetchd/blob/master/docker-compose.yml). By default it will launch a small 3 validator nodes network.\n\n## Resources\n\n1.
