reading main thread, https://bitco.in/forum/threads/announcement-bitcoin-project-to-full-fork-to-flexible-blocksizes.933/
it seems that rocks is actually working at the definitive client for the fork
it seems that there will be a dedicated web site too
Would it be possible to launch without the old blockdata? I think this would attract more people to join in. It should be enough to keep the UTXO as it was at a certain block. For the ultra paranoid this UTXO could still be verified using the pre fork bitcoin blockchain. For everyone else it would be 70GB less to start. Im not sure how viable this is to implement given the current state of the development.
