420000 uint256
- block height
- Bitcoin block height of the second halving (block reward 25 to 12.5 BTC), mined 9 July 2016; the first block with the reduced subsidy is 420000 (3 halvings schedule: every 210000 blocks)
- sources
- en.bitcoin.it, bitcoin block 420000 (mined 2016-07-09) is the widely-documented block at which the block subsidy halved from 25 btc to 12.5 btc; this is recorded consistently across bitcoin block explorers (e.g. blockchain.com, blockstream.info) and historical references such as the bitcoin wiki's 'controlled supply' page., bitcoin block 420000, mined 2016-07-09, is the well-documented and widely corroborated block at which the second block-subsidy halving occurred (reward dropped from 25 btc to 12.5 btc);
