General Discussion / Re: My opinion on why Stealth, Backups and Sidechains should not be added
« on: June 09, 2016, 05:11:01 am »There's lots of details I don't have time to go into now, but the essence of the technique is to extract sufficient data from one blockchain to create a proof-of-burn (or proof-of-lock) that the other blockchain will accept if published to that blockchain. On etherium, a smart contract would serve as the arbiter for that proof. On a graphene blockchain, the validation would be built into the blockchain protocol. Most of the details lie in how to efficiently construct such proofs. Part of the proof is information that indicates the owner on the blockchain accepting the proof.I haven't had time to read this whole thread, but Eric and I worked out a way earlier today to do a fully-decentralized version of sidechains that doesn't require multi-sig authorities, which from my limited reading would overcome the major objection originally expressed about sidechains in the OP. It wasn't prompted by this post, but by interest in linking graphene-based chains to ethereum (the original impetus being to link to ethereum as part of a move to get DAO support for peerplays). There's a fair amount of work involved in the implementation, but not an insurmountable amount by any means. So if peerplays is successful in getting DAO funding, it looks like we'll make this happen.
I find that very hard to believe, because I had convinced myself this is fundamentally impossible. Very interested to see what your solution is, what its limitations are, and whether it actually addresses any of the concerns of the OP.
