BTC: BIP30 Coinbase Outputs Overwritten — Count

Bitcoin BIP30 Coinbase Outputs Overwritten — Count was 0 outputs on 7 Nov 2026 (latest daily value).

How many Bitcoin miner reward outputs were removed because a later, identical reward transaction overwrote them (BIP30), per hour or day.

Why use it. Twice, in November 2010, a block reward transaction was repeated exactly and wiped out the earlier output; this makes those removals visible. How to read it. Zero everywhere except the periods in which the two overwrites fell. It says nothing about miners' reserves or who owns the coins.

Calculation. Exact definition: The number of coinbase outputs removed from the spendable stock by canonical BIP30 overwrites in each UTC hour or day. The ledger removes only two canonical BIP30 overwritten outputs, so values are zero outside the periods in which those removals fall. Each point sums exact output observations across the whole UTC period. This does not measure miner reserves, ownership or entities. Count the canonical BIP30 overwritten coinbase outputs recorded across the entire UTC period in our exact unspent coinbase-output ledger, which removes them from the stock. In that ledger, coinbase outputs include subsidy and actual claimed fees, immature outputs are included, and genesis and provably unspendable scripts are excluded from the stock.
