Answer
21
- million coins
- 1,000,000 BTC; the source states a cap of 21,000,000 BTC, which is 21 million BTC.
- sources
- bitcoin.org, bitcoin core / bitcoin protocol documentation (bitcoin.org, en.bitcoin.it controlled supply) stating the hard-coded 21,000,000 btc maximum supply, bitcoin core / bitcoin protocol specification (bitcoin.org, "what is bitcoin?"): total supply is capped at 21 million btc by consensus rules, bitcoin core / bitcoin protocol specification: total supply is capped at 21,000,000 btc due to the fixed halving schedule (block subsidy halves every 210,000 blocks, converging to a hard cap), as documented at https://developer.bitcoin.org/devguide/block_chain.html and reflected in bitcoin core source (chainparams.cpp reward schedule)., bitcoin core / bitcoin.org developer documentation: the protocol enforces a hard cap of 21,000,000 btc via the block subsidy halving schedule (50 btc per block halving every 210,000 blocks, asymptotically approaching 21 million)., bitcoin core consensus rules (chainparams.cpp, max_money = 21,000,000 * coin); bitcoin whitepaper (bitcoin.org/bitcoin.pdf) states the fixed 21 million coin cap, bitcoin core protocol consensus rule: total issuance is capped at 21,000,000 btc, enforced by the fixed block-subsidy halving schedule (initial 50 btc subsidy halving every 210,000 blocks), as documented in the bitcoin whitepaper and bitcoin core source (validation.cpp getblocksubsidy), bitcoin core protocol consensus rules (21,000,000 btc hard cap enforced by the halving schedule); consistent with the bitcoin whitepaper and bitcoin.org developer reference., bitcoin core protocol consensus rules (21,000,000 btc hard cap, per the reference client and whitepaper) as summarized at https://developer.bitcoin.org/devguide/block_chain.html, bitcoin core protocol consensus rules (max_money = 21,000,000 btc, enforced via the halving subsidy schedule defined in src/validation.cpp / chainparams.cpp); consistent with the bitcoin whitepaper and bitcoin.org documentation., bitcoin core source (chainparams.cpp / subsidy halving schedule) and widely cited bitcoin protocol documentation stating the hard cap of 21,000,000 btc, bitcoin core source (chainparams.cpp, max_money = 21000000 * coin) and bitcoin wiki 'controlled supply' — bitcoin's protocol-enforced maximum supply is 21,000,000 btc, i.e. 21 million coins., bitcoin core source (chainparams.cpp, max_money = 21000000 * coin) and the bitcoin protocol documentation, which fix the hard-capped maximum supply at 21,000,000 btc, bitcoin core source (max_money = 21000000 * coin in consensus/amount.h) and the bitcoin whitepaper/protocol documentation, both stating the fixed 21 million btc supply cap, bitcoin core source (src/amount.h, max_money = 21000000 * coin), consistent with the bitcoin whitepaper and protocol documentation at bitcoin.org, bitcoin core source (src/consensus/consensus.h / validation.cpp, max_money = 21000000 * coin), as documented on developer.bitcoin.org's block chain/supply reference, bitcoin core source (src/validation.cpp / chainparams) and bitcoin.org developer documentation, both stating the protocol-enforced maximum supply of 21,000,000 btc, bitcoin core source (src/validation.cpp / chainparams.cpp, max_money = 21000000 * coin) and the bitcoin whitepaper (section 3), both stating the hard-capped 21,000,000 btc maximum supply, bitcoin core source / developer documentation (bitcoin.org: 'bitcoin has a maximum supply of 21 million coins'), consistent with the halving schedule of 50 btc per block halving every 210,000 blocks summing to 21,000,000 btc, bitcoin core source code (chainparams.cpp, max_money = 21000000 * coin) and the bitcoin protocol specification; corroborated by bitcoin.org developer documentation stating the hard cap of 21,000,000 btc set by the block subsidy halving schedule, bitcoin core source code / bitcoin.org developer documentation: total subsidy sum over all halving eras converges to 20,999,999.9769 btc, commonly stated as a 21,000,000 btc maximum supply, bitcoin protocol consensus rule (21,000,000 btc hard cap), as documented at bitcoin.org/en/how-it-works and the bitcoin core reference client source (chainparams.cpp, subsidy halving schedule converging to 21e6 btc), bitcoin protocol consensus rule (21,000,000 btc hard cap), as documented in bitcoin core source and widely cited references (e.g. bitcoin wiki: controlled supply), bitcoin protocol consensus rule (21,000,000 btc hard cap), as documented in the bitcoin core source (chainparams.cpp, coin * 21000000) and the original bitcoin whitepaper/wiki., bitcoin protocol consensus rule (21,000,000 btc hard cap), as documented in the bitcoin core source (chainparams.cpp, max_money = 21000000 * coin) and widely cited references such as the bitcoin wiki (https://en.bitcoin.it/wiki/controlled_supply), bitcoin protocol consensus rule (bitcoin core reference client / bitcoin.org developer documentation): total issuance is capped at 21,000,000 btc via the halving schedule., bitcoin protocol consensus rule (implemented in bitcoin core), as summarized on https://en.bitcoin.it/wiki/controlled_supply — total supply is capped at 21,000,000 btc due to the halving schedule converging geometrically., bitcoin protocol consensus rule: hard cap of 21,000,000 btc, as fixed in the bitcoin core source code (subsidy halving schedule) and documented at bitcoin.org/en/how-it-works, bitcoin protocol consensus rule: hard-capped issuance schedule (halving every 210,000 blocks) converges to a maximum supply of 21,000,000 btc, as specified in bitcoin core's source and documented at https://developer.bitcoin.org/devguide/mining.html, bitcoin protocol consensus rule: hard-capped maximum supply of 21,000,000 btc, enforced by the halving schedule coded in bitcoin core (as documented at bitcoin.org and the bitcoin core source)., bitcoin protocol consensus rule: total issuance is capped at 21,000,000 btc due to the halving schedule (subsidy halves every 210,000 blocks, converging to a hard cap), as specified in bitcoin core's source and documented in the original design (nakamoto, bitcoin: a peer-to-peer electronic cash system, and https://github.com/bitcoin/bitcoin)., bitcoin protocol consensus rule: total issuance is capped at 21,000,000 btc due to the halving schedule converging geometrically (per bitcoin core reference implementation and the original bitcoin whitepaper/protocol design)., bitcoin protocol consensus rule: total supply is capped at 21,000,000 btc due to the halving schedule and integer division in block subsidy calculation, as documented in the bitcoin whitepaper and reference implementation (bitcoin/bitcoin src/validation.cpp getblocksubsidy / max_money constant)., bitcoin protocol consensus rules (21,000,000 btc hard cap), as documented in the bitcoin core source and bitcoin wiki (https://en.bitcoin.it/wiki/controlled_supply), bitcoin protocol consensus rules (21,000,000 btc hard cap), as documented in the bitcoin whitepaper and bitcoin core source (chainparams.cpp / getblocksubsidy halving schedule), bitcoin protocol consensus rules (21,000,000 btc hard cap), as documented in the bitcoin whitepaper and widely-cited reference sources such as the bitcoin wiki (https://en.bitcoin.it/wiki/controlled_supply) and river.com/learn/what-is-bitcoins-max-supply, bitcoin protocol consensus rules (21,000,000 btc hard cap, as documented in bitcoin core source and the original bitcoin whitepaper/specification), bitcoin protocol consensus rules (bitcoin core reference client / bip subsidy schedule) as documented at https://developer.bitcoin.org/devguide/block_chain.html and en.bitcoin.it/wiki/controlled_supply, stating the fixed maximum supply of 21,000,000 btc, bitcoin protocol consensus rules (bitcoin core source, chainparams.cpp max_money = 21,000,000 btc), bitcoin protocol consensus rules (bitcoin core source, chainparams.cpp, max_money = 21000000 * coin);
