COAL is an accelerated proof-of-work token based on ORE.

API

• Consts – Program constants.
• Error – Custom program errors.
• Event – Custom program events.
• Instruction – Declared instructions and arguments.

Instructions

• Claim – Distributes COAL from the treasury to a miner.
• Close – Closes a proof account returns the rent to the owner.
• Open – Opens a new proof account for a miner.
• Mine – Verifies a hash and increments a miner's claimable balance.
• Stake – Stakes COAL with a miner to increase their multiplier.
• Reset – Resets the program for a new epoch.
• Update – Updates a proof account's miner authority.
• Initialize – Initializes the program and creates the global accounts.

State

• Bus - An account (8 total) which tracks and limits the amount COAL mined each epoch.
• Config – A singleton account which manages program-wide variables.
• Proof - An account (1 per user) which tracks a miner's current hash and current stake.
• Treasury – A singleton account which has authority to mint COAL and holds onto user stake.
