You already are in that boat. If your paper wallet has only the private key (as 100% of them do today). You'll have no idea what coins have been assigned to it, or what their TXids are. You'll need to contact a public index (which isn't a service existing nodes provide) or synchronize the full blockchain history to find it. Both are also sufficient for jl2012's (/Petertodd's STXO), they'd only be providing you with somewhat more data. If instead, you insist that you'd already be running a full node and not have to wait for the sync, then again you'd also be your own archive. In none of these cases do you lose anything. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
