Answer
2,016
2016 uint256
- halvingCount
- the second halving is the block-reward reduction at Bitcoin block height 420000, counting the genesis-era 50 BTC reward as the first era (i.e. the 2012 event is the first halving, 2016 the second)

this is a well-established historical fact independent of ethereum chain state, consistent with bitcoin block-time explorers and historical halving records., bitcoin block 420000, mined 2016-07-09, is the widely documented second halving event (reward dropped from 25 to 12.5 btc), per bitcoin block-reward-halving historical records., bitcoin block 420000, mined 2016-07-09, reduced the block subsidy from 25 to 12.5 btc; this is the widely documented second bitcoin halving (first halving: block 210000, 2012-11-28), bitcoin block 420000, the second halving block, was mined on 2016-07-09 (utc), per the bitcoin blockchain's own timestamp record (corroborated by public block explorers such as blockchair.com/bitcoin/block/420000 and mempool.space/block/420000)., bitcoin block explorer / historical record: bitcoin block 420,000 (the second halving, reducing the block subsidy from 25 btc to 12.5 btc) was mined on 2016-07-09 utc, bitcoin block explorer / historical record: bitcoin block 420000, mined 2016-07-09 utc, which halved the block subsidy from 25 btc to 12.5 btc, is the second halving after the genesis block (first halving was block 210000 in 2012)., bitcoin block explorer / protocol history (e.g. mempool.space, blockchain.com block height 420000 timestamp): bitcoin's second block-subsidy halving occurred at btc block height 420000, mined 2016-07-09, i.e. the year 2016., bitcoin block explorer / protocol history: bitcoin's second block-subsidy halving occurred at btc block height 420000 on 2016-07-09, reducing the reward from 25 to 12.5 btc, bitcoin block explorer / protocol history: block 420000, mined 2016-07-09 utc, was the second bitcoin halving (reward dropped from 25 to 12.5 btc), following the first halving at block 210000 on 2012-11-28., bitcoin block explorer / protocol history: block 420000, mined 2016-07-09, was the second halving (subsidy reduced from 25 btc to 12.5 btc per block), consistent with the bitcoin wiki 'controlled supply' halving schedule, bitcoin block explorer / protocol history: block 420000, the second block-subsidy halving, was mined on 2016-07-09 (year 2016), bitcoin block explorer / protocol history: the second bitcoin halving occurred at block height 420,000 on 2016-07-09, reducing the block subsidy from 25 btc to 12.5 btc (the first halving occurred 2012-11-28 at block 210,000)., bitcoin block height 420,000 (the second halving block) was mined on 2016-07-09 (utc), per bitcoin blockchain historical records (e.g. blockchain.com / blockchair block explorers and widely documented bitcoin halving history)., bitcoin block height 420000 (the second halving block) was mined on 2016-07-09 utc, as recorded by public bitcoin block explorers (e.g. blockchain.com/btc/block/420000, mempool.space) and widely documented halving-history references., bitcoin block height 420000 timestamp (2016-07-09 utc), the well-documented second halving event, as recorded by public bitcoin block explorers and widely cited historical references, bitcoin block height 420000, mined 2016-07-09 utc, is the well-documented second halving block (subsidy reduced from 25 btc to 12.5 btc); this is a fixed historical fact of the bitcoin protocol's block-reward schedule, independent of the ethereum mainnet block window pinned for this request., bitcoin block height 420000, mined 2016-07-09 utc, is the widely documented second halving event (block reward reduced from 25 to 12.5 btc), as recorded by bitcoin block explorers (e.g. blockchain.com/explorer, block 420000) and historical halving references., bitcoin block reward halving schedule (bitcoin wiki 'controlled supply' / 'block reward halving' page), which records the second halving at bitcoin block height 420000 on 2016-07-09, i.e. the year 2016., bitcoin blockchain history: the second halving occurred at block height 420,000, mined on 2016-07-09 (utc), when the block subsidy dropped from 25 btc to 12.5 btc. this is a well-documented, widely-corroborated historical fact about the bitcoin network (independent of the ethereum chain/window pinned above, which only timestamps this request)., bitcoin protocol/blockchain history: the second halving occurred at bitcoin block height 420,000, mined on 2016-07-09 (block timestamp consistent across public bitcoin block explorers, e.g. blockchain.com and mempool.space historical block data)., bitcoin wiki, 'halving' article and bitcoin core src/consensus/params (nsubsidyhalvinginterval = 210000);
