Both wallet and server side implementations will be based on existing code in me-friendly language (C++>Python>anything else). I don't have a time for it right now but Crypto hackathon in Parallel Polis (http://cryptohack.org/) seems like good opportunity for it. I will let you know then. 2015-02-

If you decide to implement this in an existing or new bitcoinj based wallet, then I'm happy to give you pointers on how to do it. Making one-off, cross platform app specific wallets is pretty easy these days. For 2-of-3 dispute mediation transactions they'd start out being kind of specialist so ask

I know about that wiki page. I just wanted to design protocol which would make it easier in practice. (now it would be done manually) I could look at implementing it someday, but now I'd like to receive feedback from community. 2015-01-31 19:19 GMT+02:00 Mike Hearn : > Hi Martin, > > You're on th

Hi Martin, You're on the right lines. Your writeup is pretty similar to the high level overview given here though: https://en.bitcoin.it/wiki/Contracts#Example_2:_Escrow_and_dispute_mediation To make 2-of-3 dispute mediation works requires implementing a wallet that supports it, and the tools me
