#881423 FutureBit block! Looks to be the same one that hit a block before, #867760 also it looks like they are mining with a lot of miners thru it. Hashrate (24h) 5.1 EH/s
So they did kind of a Bitcoin-block telethon where several miners pointed their hash to this guy's Apollo node and that's how they hit a block. Don't have the details, but it was mentioned on BitsBeTrippin youtube video just released on solo mining.
