Design

The README says Bitcoin New “is a fork of the Bitcoin blockchain that will occur at block height 501000”, around 25 December 2017, after which miners would use a new proof-of-work algorithm[1]. Block 501,000 was mined on 25 December 2017 at 17:42 UTC[2]. forkdrop's data file gives a maximum supply of 2.1 Billion[3].

Record

The 2019 fork list says “no source code available” and that it “doesn't seem to exist (anymore)”[4]. The “no source code” note conflicts with the GitHub repository that forkdrop links[3], whose README was still online on 13 November 2026[1]. forkdrop's data file files Bitcoin New among historic entries with the reason “Reneged”[3]. Not to be confused with New Bitcoin (NBTC)[3].
