Description
Overview
This chart tracks the number of accepted transactions each day that use the OpChainblockSeqCommit opcode (0xd4). The opcode lives in an output's
script, so a transaction is counted when it creates an output whose script uses it, or spends
a pay-to-script-hash output whose revealed redeem script uses it. This opcode sits within the
introspection opcode range, so these transactions are a subset already counted in the
Introspection Opcode Transactions metric.
How This Data is Collected
Each accepted transaction is scanned for the OpChainblockSeqCommit opcode in an output
script, or in the redeem script revealed by a pay-to-script-hash spend, then grouped by day. A
transaction is counted once regardless of how many times the opcode appears.
