Non-Standard Bitcoin Transaction Dataset

This is the overview page for the bitcoin-data non-standard Bitcoin transaction dataset. The dataset is generated with the non-standard tx finder tool. As of writing (February 2024), the tool uses a Bitcoin Core v25 test-node with the extra command line parameters "-limitancestorcount=26 -limitdescendantcount=26 -maxtxfee=0" to work around some methodology limitations. Note that the dataset starts in late 2021. It's updated sporadically.

dust: transaction with an output value smaller than the dust limit.

multi-op-return: transaction with multiple OP_RETURN outputs
bad-txns-nonstandard-inputs: transactions with non-standard inputs
