Bitcoin Cash NodeBCHN
The Bitcoin Cash full-node client that took over from Bitcoin ABC when ABC's funding rule split off in November 2020.
The wiki's angle: BCHN is the answer to “who kept the BCH ticker in 2020”. The magazine and the podcast both frame the split as a fight over a development tax, not over block size.[2][1]
From ABC to BCHN
On S17 E26, Bitcoin Cash developer Calin Culianu described the client's origin: “it was Bitcoin ABC until Amaury decided to charge tax, and then we kicked them out. And then we renamed it to Bitcoin Cash Node, BCHN”[1]. He said it is the node most people run, alongside others such as BCHD and Knuth, and that its codebase is the one ultimately derived from Bitcoin Core[1].
The 2020 split
On 15 November 2020 Bitcoin ABC's chain split from Bitcoin Cash at block 661,648 over the 8% coinbase rule, and traded as BCHA[2]. The chain that rejected the rule kept the Bitcoin Cash name and the BCH code[3]. See ABC vs BCHN split.
