Alephium Mining Companion

This project is a companion for Alephium full nodes, providing some convenience features when enabling mining:

1. Creates a mining wallet if none exists. It can also restore the wallet if mnemonics are provided.
2. Configures the mining process to use the created wallet, if one created or different from the one configured.
3. Starts the mining automatically when the node is in sync
4. Transfers the mining reward to another provided wallet/address on a fixed frequency (hourly, daily, ...). Note that the wallet can be created anywhere as long as it's a valid Alephium address
5. Expose metrics for both the mining and the transfer wallets

Companion means it needs to run alongside an Alephium full node, and particularly have REST connectivity to it (default port 12973)

Configuration

Docker compose

Docker-compose is a good way of running the side, assuming the Alephium node is also running in docker.

version: "3"
services:
  mining-companion:
    image: touilleio/alephium-mining-companion:v6
    restart: unless-stopped
    security_opt:
      - no-new-privileges:true
    environment:
      - ALEPHIUM_ENDPOINT=http://broker:12973
      - LOG_LEVEL=debug
      - WALLET_NAME=$miningWalletName
      - WALLET_PASSWORD=$miningWalletPassword
      - WALLET_MNEMONIC=$miningWalletMnemonic
      - TRANSFER_ADDRESS=$miningTransferAddress
      - TRANSFER_FREQUENCY=5m
      - TRANSFER_MIN_AMOUNT=50000000000000000000
      - IMMEDIATE_TRANSFER=true
      - START_MINING=false

with variables miningWalletName, miningWalletPassword, miningWalletMnemonic and miningTransferAddress in a .env file in the same folder as the docker-compose.yml.

Variable	Default	Description
ALEPHIUM_ENDPOINT	http://alephium:12973	REST URI of your Alephium node. Mind localhost in a docker container point to the docker container, not the host itself.
ALEPHIUM_API_KEY	optional	API key to use to connect to ALEPHIUM_ENDPOINT.
WALLET_NAME	mining-companion-wallet-1	Name of the miner wallet
WALLET_PASSWORD	Default-Password-1234	Password to unlock the miner wallet
WALLET_MNEMONIC	optional	Mnemonic to restore (create) the wallet if it does not exist. Random mnemonic will be generated if not set
WALLET_MNEMONIC_PASSPHRASE	optional	A passphrase associated with the mnemonic, if any
TRANSFER_MIN_AMOUNT	20000000000000000000 (20 ALF)	Min amount to transfer at once. It uses the sweepAll function to optimize the transaction.
TRANSFER_ADDRESS	optional	Address to transfer the mining rewards to. If none provided, no transfer is performed. Double check you're sending the funds to the right address !!
TRANSFER_FREQUENCY	15m	Frequency at which funds are transferred
PRINT_MNEMONIC	true	If true and a wallet is created without pre-set mnemonic (WALLET_MNEMONIC option above), the randomly generate mnemonic is printed out. This is a sensitive information, use it with caution!
IMMEDIATE_TRANSFER	false	If set to true, a transfer is sent at the start of the container, without waiting for TRANSFER_FREQUENCY initial time
START_MINING	false	If set to true, the mining machinery built-in the broker will start mining. This is disabled by default and the dedicated, more efficient CPU miner is recommended for mining as the time of writing

Docker

Replace 123456789012345678901234567890123456789012345 below with your own wallet address!

docker run -it --rm --link alephium:alephium -e TRANSFER_ADDRESS=123456789012345678901234567890123456789012345 touilleio/alephium-mining-companion:v6

As a reminder, running a Alephium full node looks like the following:

docker run -it --rm --name alephium -p 12973:12973 alephium/alephium:v1.1.7
