Pitch

The archived site, captured on 10 May 2018, introduces “the first eco-friendly crypto currency” and announces the hard fork at “Block #518.800” on “Tuesday, April 18th, 2018, 5:26:13 PM (UTC)”[1]. Bitcoin block 518,800 has a header time of 15:26:13 UTC on 18 April 2018, a Wednesday, two hours earlier than the time the site gave[2]. The site says bitcoinClean “introduces the proof-of-greenness protocol to verify the use of green energy” and that “Every node must undergo a peer review to participate in the network”[1]. It also lists 8MB blocks[1].

Record

The 2019 fork list says it “doesn't seem to be working anymore, 0.3 GB, last synced block 588600 on 11/10/2018”[3]. On 1 May 2018 a fork-transaction tool added “Bitcoin Clean "BCL"”, in a post that warned one of the newly added forks had no replay protection[4].
