Not every node is an archive node; that's even the case today.

The private key is already not enough, and no Bitcoin node will just give you what you need to know. The only additional information JL2012's scheme would add would be the hash tree fragments to show membership; and the same places that currently give you what is required to author a transaction could provide it for you. > included.

The system already inhibits the rate new UTXO can be added; but we're still left with the perpetually growing history that contains many lost and otherwise unspendable outputs. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
