Methodology and related types
Counts and values are derived from the canonical Bitcoin chain through the published block. Created equals current UTXOs plus spent or otherwise removed plus outputs that never entered the UTXO set.
Gross output value is value flow, not circulating supply. “Spent” reports the original value carried by consumed outputs.
