Bitcoin RM (BCRM)BCRM
Not a chain split: a new chain seeded with a Bitcoin UTXO snapshot (a snapshot fork). Kept off the lineage map.
A 2018 smart fork for retail merchants: a clean chain seeded with a 20 August 2018 UTXO snapshot, with claims open to non-US holders until the end of 2018.
The wiki's angle: Bitcoin RM excluded US owners and addresses that cannot sign messages, so many BTC holders could never claim.[4]

Record
The README says “We start with a clean blockchain, without copying the blockchain of Bitcoin. We take a snapshot of UTXOs on August 20, 2018.”[1] forkdrop's data file gives block 537746[2]. Block 537,746 was mined on 21 August 2018 UTC[3]. The thread says eligible non-USA owners with at least 0.001 BTC could claim, that “Users with Bitcoin addresses starting with 3 or bc cannot sign messages and therefore cannot claim”, and that “The claims deadline was December 31, 2018”[4]. It lists 60-second blocks, 20MB blocks, a 1 Billion supply and a 5% founders' fee[4].
