That seemed tight. Can you please elaborate on what terrible things will happen if we don't increase the block size by winter this year? I assume that you are expecting full blocks by then, have you used any statistical technique to come up with that date or is it just your guess? Because I love wild guesses and mine is that full 1 MB blocks will not happen until June 2017. > What we need to see right now is leadership and a plan, that fits in the > available time window. > >> >> Certainly a consensus in this kind of technical community should be a >> basic requirement for any serious commitment to blocksize increase. > > > I'm afraid I have come to disagree.

We've successfully reached consensus for several softfork proposals already= . I agree with others that hardfork need to be uncontroversial and there should be consensus about them. If you have other ideas for the criteria for hardfork deployment all I'm ea= rs. I just hope that by "What we need to see right now is leadership" you don't mean something like "when Gaving and Mike agree it's enough to deploy a hardfork" when you go from vague to concrete. >> Long-term incentive compatibility requires that there be some fee >> pressure, and that blocks be relatively consistently full or very nearly >> full. > > > I disagree.

Oh, so your answer to "bitcoin will eventually need to live on fees and we would like to know more about how it will look like then" it's "no bitcoin long term it's broken long term but that's far away in the future so let's just worry about the present". I agree that it's hard to predict that future, but having some competition for block space would actually help us get more data on a similar situation to be able to predict that future better. What you want to avoid at all cost (the block size actually being used), I see as the best opportunity we have to look into the future. >> What we see today are >> transactions enjoying next-block confirmations with nearly zero pressure >> to include any fee at all (though many do because it makes wallet code >> simpler). > > > Many do because free transactions are broken - the relay limiter means > whether a free transaction actually makes it across the network or not is > basically pot luck and there's no way for a wallet to know, short of eith= er > trying it or actually receiving every single transaction and repeating th= e > calculations.

That's great but we shouldn't rely on them for the future. They will likely disappear at some point and that's ok. In any case, he's not complaining about the lack of free transactions, more like the opposite. He is saying that's very easy to get free transactions in the next block and blocks aren't full so there's no incentive to include fees to compete for the space. We can talk a lot about "a fee market" and build a theoretically perfect fee estimator but we won't actually have a fee market until there's some competition for space. Nobody will pay for space that's abundant just like people don't pay for the air they breath. > What I don't see from you yet is a specific and credible plan that fits > within the next 12 months and which allows Bitcoin to keep growing.

Ok, this is my plan: we wait 12 months, hope that your estimations are correct (in case that my guess was better than yours, we keep waiting until June 2017) and start having full blocks and people having to wait 2 blocks for their transactions to be confirmed some times. That would be the beginning of a true "fee market", something that Gavin used to say was his #1 priority not so long ago (which seems contradictory with his current efforts to avoid that from happening). Having a true fee market seems clearly an advantage. What are supposedly disastrous negative parts of this plan that make an alternative plan (ie: increasing the block size) so necessary and obvious. I think the advocates of the size increase are failing to explain the disadvantages of maintaining the current size. It feels like the explanation are missing because it should be somehow obvious how the sky will burn if we don't increase the block size soon. But, well, it is not obvious to me, so please elaborate on why having a fee market (instead of just an price estimator for a market that doesn't even really exist) would be a disaster.
