A small site that tracks Bitcoin's UTXO set:
https://gettxoutset.info/It's a read-only explorer for the
gettxoutsetinfo RPC. For every block it records one snapshot and stores its MuHash, so you can compare that against what your own node computes and confirm your chain state lines up.
To check it yourself, run on your Bitcoin Core:
bitcoin-cli gettxoutsetinfo muhash <height>
Then compare the
muhash field to the value listed on the site for that height. If they match, your node and the site independently ended up with the same set of unspent outputs. If they don't, something's off (corrupted data, a bug, or a different chain).
No accounts, no tracking, just the numbers. Sharing in case it's useful for initial block download or fast sync.
