This chart tracks the throughput of the Bitcoin`s base blockchain. Transactions and value transmitted on layer-2, such as sidechains and the Lightning Network, are not included.
Since a Bitcoin transaction may have many payment outputs, in this chart we are tracking the cost per payment output. This accounts for transaction batching, a technique used by exchanges where many payments are efficiently rolled into a single transaction.
Payment count inside a single transaction is estimated by counting the total outputs and subtracting one, with the assumption that it is the unspent change (UXTO).
