I'd like to discuss the pros/cons of implementing lattice signatures in bitcoin now such that when ECDSA is broken it's an orderly transition to use a different lock on funds.
If you want, we can discuss this here, or you can email me or the bitcoin-dev mailing list directly with the possibility of starting a discussion about
one of these quantum-resistant schemes and the possibility to make a new Bech32 address type that utilizes them.
I'd also like to suggest that we add an optional PoW on a transaction submitted to a node so that when someone submits their transaction they can provide a PoW of that Tx alongside to the node to show they really want the tx to be included.
This will not work, because computers and smartphones are not ASICs and they can't possibly be expected to create a hash for transactions. Besides, this will require a complete rewrite of the bitcoin protocol, which is so used to the methodology: transactions --> blocks.
