The blockchain for GRF isn't working because there is hardly any users that have kept are are keeping their wallets online, the main reason for the dropouts is because there is no seednode that is on the agreed latest block, people are just trying to connect to each other and download whatever parts of the forked blockchains they have, once that has been sorted or even an updated wallet to reflect those changes will it start working as intended.
No one said there is any forked blockchain. Nothing really needs to be sorted about this. But yes are right there is no working seednode. If you or anyone still has his wallet online, just need to post the ip address publicly here, so that all others can connect to this same ip. If everyone can connect to one common ip. it works exactly the same as a seednode.
