Of course, the big debate around scaling bitcoin in recent months has revolved around increasing the block size. When discussing the difficulties with gaining consensus among the core bitcoin development team, Andresen let it be known that he’s getting closer to scheduling a hardfork for the purpose of increasing the block size in an upcoming release of Bitcoin Core:
“I’m actually, right now, working on just getting consensus among the five, what I call, core developers — the five developers who have push access to the git code. I think I’m getting close to convincing them that we have a plan that will work. I’m probably going to have to write some more code . . . I think we have a year to eighteen months. I would love the next release of bitcoin — the next major release, which will be sometime in the June timeframe — to have a scheduled hardfork to increase the block size in it. I probably won’t get there. It’ll probably be in the release after that, but we’ll see.”
