From ben at mord.family Tue May 8 12:44:41 2018 From: ben at mord.family (Benjamin Mord) Date: Tue, 08 May 2018 12:44:41 +0000 Subject: [Lightning-dev] Scriptless Scripts with ECDSA In-Reply-To: References: <39f93652-666d-8864-5b3e-0141f3e45085@purdue.edu> Message-ID: If I'm not mistaken, the scriptless scripts concept (as currently formulated) falls to Schor's algorithm, and at present there is no alternative implementation of the concept to fall back on. Correct? Lest we build a house of cards, I'd strongly urge everyone to not depend on functional concepts whose underlying cryptographic primitives cannot be swapped in an emergency. Sure, we use ecdsa for example (which is also vulnerable to Schor's algorithm), but in contrast to scriptless scripts we have a variety of backup primitives at our disposal that fulfill the same functional objective. If scriptless scripts are found possible under lattice-based cryptography for example, that would be something I suppose. The functional concept of scriptless scripts is indeed very awesome - we just need to add some cryptographic conservatism before we build on it. -------------- next part -------------- An HTML attachment was scrubbed...
