A $TUNA miner, written in Go
Bluefin is self-contained and runs with no external dependencies. You can run it via the Docker images or binaries from the releases page.
Bluefin is designed to take its configuration from environment variables. All examples below show running the bluefin binary directly from the shell and will need to be adapted for use with Docker.
When run with no configuration, bluefin defaults to mining TUNA v1 on mainnet. It will generate a new wallet and write the seed phrase to the seed.txt file in the current directory.
$ ./bluefin
...
{"level":"info","timestamp":"2024-07-04T20:13:53-05:00","caller":"wallet/wallet.go:62","msg":"wrote generated mnemonic to seed.txt"}
{"level":"info","timestamp":"2024-07-04T20:13:53-05:00","caller":"bluefin/main.go:73","msg":"loaded mnemonic for address: addr1..."}
{"level":"info","timestamp":"2024-07-04T20:13:53-05:00","caller":"bluefin/main.go:79","msg":"starting indexer on mainnet"}
You can use the NETWORK and PROFILE environment variables to change the mode that bluefin operates in. For example, to mine TUNA v2 on preview:
$ NETWORK=preview PROFILE=tuna-v2 ./bluefin
If you want to provide your own wallet seed phrase, you can set the MNEMONIC environment variable or create the seed.txt file before running bluefin.
If allowing bluefin to generate a new wallet, you will need to seed the wallet with some initial funds using the wallet address logged at startup. If the wallet already exists, you may need to send funds back to your own wallet so that they're visible to bluefin. The wallet will need at least 2 available UTxOs, one to cover TX fees, and another of at least 5 (t)ADA to use as collateral.
By default, bluefin will use the NtN (node-to-node) TxSubmission protocol to submit transactions directly to the Cardano network. This method has the downside of not providing any feedback if a transaction fails. You can use the SUBMIT_URL environment variable to specify the URL for a submit API to use instead, which will provide feedback about any transaction validation issues.
Bluefin stores its local data in .bluefin/ in the current directory. If you run into a problem that requires clearing the data, you can delete this data and bluefin will re-sync from scratch.
This requires Go 1.19 or better is installed. You also need make.
# Build make # Run ./bluefin
You can also run the code without building a binary, first
We're looking for people to join this project and help get it off the ground.
