A fair point. I'll add some prefixes for testnet. > - Please allow M=1. From a usability point of view it makes sense to allow > the user to select 1 share if that is what he wants. How does that make sense? Decomposing a key/seed into 1 share is functionally equivalent to dispensing with the secret sharing scheme entirely. > I have no strong opinions of whether to use GF(2^8) over Shamir's Secret > Sharing, but the simplicity of GF(2^8) is appealing. I'll welcome forks of my draft BIP. I don't really have the inclination to research GF(2^8) secret sharing schemes and write an implementation at the present time, but if someone wants to take my BIP in that direction, then okay. ------------------------------------------------------------------------------ Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform _______________________________________________ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
