Blockpool Core will be moving to mainnet at block 3,402,528 (approximately 2:00 PM (GMT) on Saturday 03-Aug). This is a hard-fork to an entirely different code base, so the transition wont be seamless, but it should be easy.
As of Tues 02-Jul, Blockpool Core (BPL v2) Testnet is up and running. This is a major milestone and we hope you are excited about it as we are. But with this, we now enter the Community Testing Phase, which will require help from all of you.
