Record

The announcement of 27 November 2017 says “We fork from the evil mainstream bitcoin chain at block 501488”[1]. Its main rule is that “All inputs originating ON or BEFORE block 120001 will be INVALIDATED”, aimed at early holders[1]. It says the block size stays at 1MB[1]. Block 501,488 was mined on 29 December 2017[2]. The linked GitHub repository holds a stock Bitcoin Core README[3]. forkdrop's data file lists a 15,000,000 maximum supply[4]. Whether a chain ran is unknown[4].
