Which side do you support with the coming November Hard Fork?
Bitcoin ABC plans canonical transaction ordering, activation for OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY.
nChain plans block size to 128MB.
Imo focus on adoption & removing the BS limit, so BCH can function as global money, I don't see how lexicographic ordering will help long term, devs have enough OP's to play with now.
Canonical ordering helps in efficient block propagation (graphene), so that BCH can function as a global money. Don't look so narrow, all parts of this system are interconnected.
