The sum count of unique wallets that were active in the network (either as a destination or source of a ledger change) that day. All unique wallets involved in a ledger change action (recipients and originators) are counted. This metric does not double-count wallets. In other words, if a wallet has been deemed active by being part of a ledger change, it is not counted again if is subsequently involved in a transaction during the same time interval. Wallets represent groups of addresses that we estimate are owned by the same entity. They provide a better proxy for user behavior since users often own more than one blockchain address.
