Apparently lightning doesn't require Segregated Witnesses: cltv and rcltv may be enough (although I'm not up to date to the latest designs). I definitely don't think we should wait to have SW ready to be deployable in Bitcoin to have other hardforks. I think we should have an uncontroversial hardfork as soon as possible, if anything, to set a precedent and show the world that hardforks are possible in Bitcoin, see https://github.com/jtimon/bips/blob/bip-forks/bip-forks.org#code > Or is the plan to avoid controversy by people voluntarily moving their > bitcoin to a sidechain where all this scaling-up innovation happens? Any scaling up innovation that happens in sidechains can be adopted by Bitcoin too. In fact, some of those changes (like op_maturity/rcltv/scv) are needed in Bitcoin for a fully p2p Bitcoin sidechain to be even possible. I really think lightning should be possible in Bitcoin main (and not just sidechains) as soon as possible. > And any plan that requires inventing brand-new technology is going to be > riskier than scaling up what we already have and understand, which is why I > think it is worthwhile to scale up what we have IN ADDITION TO working on > great projects like Segregated Witness and Lightning. Not necessarily. How are older payment channels designs (different from lightning) that don't even require cltv riskier than a hardfork? In any case, yes, both things are kind of orthogonal and we can work on both (and more) at the same time. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
