List of all addresses that hold the specified Rune, together with the respective amount of that Rune.

In addition to confirmed transactions, mempool endpoints return data which reflects pending transactions in some number of "estimated" blocks - predicted blocks containing transactions which have been propagated around the network but not yet included in a mined block, with transactions with a higher sat/vB value being prioritised. The response details how many of these estimated blocks were considered when fetching the data.
