I posted about that last year.

For Hive and bitcoin it doesn't fit in. Zero proof blockchains are used by coins like Monero. Neither Hive or bitcoin are zero knowledge proof. If Hive were zero knowledge proof https://hiveblocks.com transactions would look more like https://moneroblocks.info transactions.
This is what ChatGPT says:
Monero uses a technique called "RingCT" (Ring Confidential Transactions) to obscure the amounts involved in a transaction and the identity of the sender. This technique uses a combination of ring signatures and stealth addresses to hide the origin and destination of a transaction.
Ah well, I guess we need a coin with transparency as much as one without.
