Hi publicworker, would you summarize how this proposal works? is it trustless, trully decentrilized or a kind of multisig? I always scared of spending too many times reading tech geek thing that does not solve any problem, 
I cannot see a reason to lock btc/eth (only asset worth lock) to give it in bts blockchain, even there is no scalability issue........ even if projects build on graphene, issued n traded in dex could interoperate in a plug n play way it does not make sense what benefit could be gained for value, volume, adoption......I dont see a reason either a proposal that reasonable or that makes some sense to put a work for it over the tables, the benefits are not worth in my opinion, but this is just a opinion of a pratical averajoe that does not have interest for fancy things but for. solutions that drives adoption n make useful n needed
