A snapshot fork keyed to block 498,754 that filtered early coinbase coins and two famous addresses out of its copy of the Bitcoin ledger.

◆ Takeover vieweditorial · opinion, labelled

The wiki's angle: Bitcoin@CBC is one of the few forks that edited the inherited balances on purpose, removing early coinbase coins and two named addresses.[1]

Design

The 2019 fork list calls Bitcoin CBC a “snapshot fork (no shared pre-fork blockchain history)” taken at block 498,754[1]. Block 498,754 was mined on 11 December 2017[2]. The list quotes the project saying “All unspent coinbase generated coins from 50000 first blocks from original Bitcoin blockchain were filtered (1235650 coins)” and that two well-known addresses holding 108,108 coins were deleted[1]. It also quotes a rule that each address with a positive balance was reduced by one coin, with those funds going to an ExtraReward pool[1].

Record

An April 2018 reply in the same fork-list thread summed the payout up as “n BTC = n-1 BCBC”[1]. forkdrop's data file lists the ratio as <1:1 and the maximum supply as 21,000,000[3]. forkdrop's announcement link, Bitcointalk topic 3109563, now carries the title “[CLOSED]: unnamed coin”, and the surviving posts in it advertise a Bitcoin@CBC mining pool[4]. The 2019 list found the website, Twitter account and GitHub repository gone, and its node “doesn't seem to be working anymore”, last synced at block 18,286 on 17 July 2018[1].
