About

UTXO bloat is a hot topic recently. "Spammers" aren't going away anytime soon, so it's hard to prevent further bloating... but why not incentivize shrinking? Enter Sweepstack, a service allowing people to consolidate their old UTXOs into a single Taproot output with a sponsor paying the miner fees.
