Ore is a digital currency you can mine from anywhere, at home or on your phone. It uses a novel proof-of-work algorithm to guarantee no miner can ever be starved out from earning rewards.

How it works

The primary innovation of Ore is to offer non-exclusive mining rewards. This means one miner finding a valid solution does not prevent another miner from finding one as well. Rather than setting up every miner in a winner-take-all competition against one another, Ore gives each miner a personalized computational challenge. As long as a miner provides a valid solution to their own individual challenge, the protocol guarantees they will earn a piece of the supply. Since no miner can be censored from the network and valid solutions are non-exclusive, starvation is avoided.


Ore is designed to protect holders from runaway supply inflation. Regardless of how many miners are active in the world, supply growth is strictly bounded to a rate of 0 ≤ R ≤ 2 ORE/min. In other words, linear. The mining reward rate – amount paid out to miners per valid solution – is dynamically adjusted every 60 seconds to maintain an average supply growth of 1 ORE/min. This level was chosen for its straightforward simplicity, scale agnosticism, and for striking a balance between the extremes of exponential inflation on one hand and stagnant deflation on the other.


  • Consts – Program constants.

  • Entrypoint – The program entrypoint.

  • Errors – Custom program errors.

  • Idl – Interface for clients, explorers, and programs.

  • Instruction – Declared instructions and arguments.

  • Loaders – Validation logic for loading Solana accounts.


  • Initialize – Initializes the Ore program, creating the bus, mint, and treasury accounts.

  • Reset – Resets the program for a new epoch.

  • Register – Creates a new proof account for a prospective miner.

  • Mine – Verifies a hash provided by a miner and issues claimable rewards.

  • Claim – Distributes claimable rewards as tokens from the treasury to a miner.

  • UpdateAdmin – Updates the admin authority.

  • UpdateDifficulty - Updates the hashing difficulty.


  • Bus - An account (8 total) which tracks and limits the amount mined rewards each epoch.

  • Proof - An account (1 per miner) which tracks a miner's hash, claimable rewards, and lifetime stats.

  • Treasury – A singleton account which manages program-wide variables and authorities.
