It’s possible to skip the mempool, by including it directly in a block, giving no time to a QC attacker. Not worth it right now, but if QC was known to exist it

It’s possible to skip the mempool, by including it directly in a block, giving no time to a QC attacker. Not worth it right now, but if QC was known to exist it could be done.
- greyface- 5y agoIs there a way to guarantee that this block doesn't become orphaned? A transaction isn't truly committed to the blockchain until it has several confirmations.
- tracedddd 5y agoThere’s no way to guarantee absolutely, but you could wait to announce until you got lucky with a couple consecutive blocks if you had a lot of hashpower (pool operators). It would be an expensive endeavor since it involves throwing away solved blocks, but could of course package many QC safe(r) transactions so probably a profitable service in a QC compromised era.
- simonmales 5y agoDo you mean by mining the block yourself? Or a really high transaction fee?
- tracedddd 5y agoWell, not necessarily yourself, but through an entity that would not gossip the pending transaction. If it paid well any pool or mining farm could include it. A high standard transaction fee would not help.
