A planned early-2018 fork that promised Dash-style instant transactions and masternodes; its fork height differs between its own site and the 2019 fork list.

◆ Takeover vieweditorial · opinion, labelled

The wiki's angle: Bitcoin Flash shares the BTF ticker with Bitcoin Faith, one of several ticker collisions in the fork wave, so listings that say only “BTF” need checking.[3][1]

Pitch

The archived site, captured on 1 January 2018, showed a countdown “until block 502502 on Bitcoin Core chain (~January 5, 2018)”[1]. It promised instantly confirmed transactions and said the team “reused reliable & well-tested Dash InstantX technology”, with node operators earning part of the block reward as in Dash[1]. Its spec table lists a 16 MB block size limit, a retargeting algorithm it calls “Dark Gravity Well” (Dash's algorithm is named Dark Gravity Wave), masternode collateral of 1,000 BTF and two-way replay protection[1].

Record

Bitcoin block 502,502 was mined on 4 January 2018 at 08:00:26 UTC[2]. The 2019 fork list instead gives “fork at 508000”, links the GitHub repository bitcoinflash/bitcoinflash and says the coin “doesn't seem to exist (anymore)”[3]. Block 508,000 was mined on 6 February 2018[4]. Which height was finally used is unknown to this wiki[3][1].
