A March 2014 code fork of Bitcoin 0.8.6 that swapped SHA-256 for Grøstl and still tracks Bitcoin Core releases.

◆ Takeover vieweditorial · opinion, labelled

The wiki's angle: Groestlcoin is a code fork that stayed close to its parent: it forked 0.8.6 in 2014 and kept merging Bitcoin Core work, including SegWit and Taproot, which it claims it activated first.[1][3]

Fork

The Groestlcoin Core README opens with “Forked from Bitcoin reference wallet 0.8.6 on March 2014”[1]. Its chain parameters give a genesis timestamp of 1395342829, which is 20 March 2014 at 19:13:49 UTC, and the genesis text “Pressure must be put on Vladimir Putin over Crimea”[2].

Launch and claims

The Bitcointalk announcement by gruve_p says Groestlcoin “Launched 22nd March, 2014 at 09:00 PM GMT”[3]. The thread title claims Groestlcoin was the “1st to activate Segwit & Taproot”; this wiki has not independently checked that claim against other chains' activation dates[3].
