This chart tracks key metrics that reflect congestion on the Bitcoin network:
In the past the network congested when block fill tipped above 85% of the 1MB cap. Lately with incremental improvements to the protocol, the network seems to be able to handle higher block fill without degradation of confirm times and large increases in fees
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).
