I studied with Jeffrey Hoffstein at Brown, one of the creators of NTRU. He told me recently NTRU, which is lattice based, is one of the few (only?) NIST-recommended QC-resistant algorithms. We talked over layering on NTRU to Bitcoin last year when I was out that way; I think such a thing could be

We've been toying with the idea of a 'dead' button, one that issues a bunch of pre-generated txs sending stuff out to a previously secured 'backup' set of addresses (we don't think in terms of wallets, just keypairs). In this scenario, you have a long-term storage address (or set of them), and if

OK, I have a few thoughts on this: 1) Germane to the original conversation, anything hard to implement will not get implemented by miners. 2) Coinbase is hard-limited to 100 bytes; this has to include space for voting as well as extra nonce, etc. So, I'm not sure that a full URL is a good plan.

We just implemented our own mining tool, soup-to-nuts, and I would say that the likely motivation for what I presume are botnet owners is just economic. It's a lot more work to make sure your merkleing and keeping up-to-date are happening than it is to just get an 80 byte header from a central
