Supply and emission
Bitcoin.org states the design allows for a total of 21 million bitcoins in existence and that new bitcoins are created by mining at a decreasing, predictable rate, with annual issuance automatically halved until it halts completely. There is no premine, foundation allocation, or treasury, and no allocation under vesting. Halvings are triggered by block height rather than calendar date, so no dated unlock schedule exists and future halving dates are estimates.
