There have been a handful of forks from the main Bitcoin Network over the past few months, and that seems to be continuing into the new year. Bitcoin Interest plans to fork at block 505083, on January 22, 2018.
Bitcoin Interest is the recently announced fork of the Bitcoin network, including full replay protection. They’re planning on changing a few things, but keeping more of the protocol together. For those of you who don’t know, a fork is a split in the two networks. At the time of the fork, everyone who owns Bitcoins will have the same balance of BCI if they’re holding when the fork happens. The fork will form two separate networks, with their own coins, users, merchants, and miners.
