The UTXO acronym stands for unspent transaction output. Think of it as the total number of Bitcoin bank accounts. Pruning past transactions doesn't shrink this size at all. These UTXOs have to stick around and can never[1] be pruned as they're used in future transactions. And yes, it does seem like 8 decimal places was too much for the current time and they're now correcting for that.
[1] If they really wanted to do so with a major fork it's possible but it's not nearly worth the hassle.
- trevelyan 13y agoIf people are worried about an explosion of ghost accounts with 1 satoshi (80 bytes, right?), just give unspent transaction output to miners if the receiving account has below a certain threshold of funds. Don't tell me I can't send arbitrary payments if I am willing to pay whatever the necessary transaction fee is to process them.
