full-featured Ethereum PoS simulator (private net) locally or in CI/CD,\nwith PBS (MEV) emulation support.\n\nThis project exists to provide convenient and reliable testing\nenvironment with predictable performance for Ethereum API users,\nsuch as developers of PoS blockchain automation.\n\n\nExecution client support:\n\n- [x] Geth\n- [ ] Nethermind\n- [ ] Besu\n- [ ] Erigon\n\nConsensus client support:\n\n- [x] Lighthouse\n- [x] Teku\n- [ ] Prysm\n- [ ] Nimbus\n- [ ] Lodestar\n\n\nValidator client support:\n\n- [x] Lighthouse\n- [ ] Teku\n- [ ] Prysm\n- [ ] Nimbus\n- [ ] Lodestar\n\n\nThe aim is to eventually support all Ethereum clients featured at\n[official documentation](https://ethereum.org/en/developers/docs/nodes-and-clients/).\n\n\nHow to use\n----------\n\nThe primary interface for users is the container one,\naccessed via `docker compose` utility (docker compose v2, do not confuse with\nv2 of the docker-compose spec, which is obsolete).\n\nFirst, chose how you want to run the project and save your configuration in the\n`.env` file:\n\n* if you're using the opus devpod (internal chorus one project) run:\n```bash\necho \"COMPOSE_FILE=compose-devpod.yaml\" \u003e .env\necho \"COMPOSE_PROJECT_NAME=${C1_DOCKER_NAMESPACE}-possim\" \u003e\u003e .env\necho \"POSSIM_DOCKER_NETWORK=${C1_DOCKER_NETWORK}\" \u003e\u003e .env\necho \"POSSIM_BINDMOUNT_PATH=$(host-path-outside-of-docker.sh .)\" \u003e\u003e .env\necho \"POSSIM_HOSTNAME=possim.devel\" \u003e\u003e .env\n```\n* otherwise for linux host networking configuration run: \n```bash\necho \"COMPOSE_FILE=compose-host.yaml\" \u003e .env\necho \"POSSIM_HOSTNAME=127.0.0.1\" \u003e\u003e .env\n```\n\nOnce you've set up your env you can get the privatenet up and running using:\n\n```bash\ndocker compose build possim\ndocker compose run --use-aliases --rm possim\n```\n\nOnce running, you can connect using:\n\n```bash\nsource .env\ncurl -v http://$POSSIM_HOSTNAME:15050\n```\n\nTo run with overridden config:\n\n```bash\ndocker compose run --use-aliases --rm possim CONFIG=/opt/privatenet/pbs_config.yaml\n```\n\nSee [configuration.yaml](./eth_possim/resources/configuration.yaml) for the default values.\n\nHow to test\n-----------\n```bash\ndocker compose run --rm possim test\n```\n\nHow it works inside the container\n----------------------------------\nFirst, a command `python3 -m eth_possim generate` generates configuration for all\nthe components.\n\nThen, `tilt up` command starts the blockchain.\n\nAnd finally, `make` file binds generation and tilt start together.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchorusone%2Feth-possim","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchorusone%2Feth-possim","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchorusone%2Feth-possim/lists"}
