Not a Bitcoin chain split: a separate platform with a registration airdrop to BTC holders. Kept off the lineage map.

A 2017 BFT smart-contract platform that forkdrop lists as a registration airdrop keyed to Bitcoin block 480,000.

◆ Takeover vieweditorial · opinion, labelled

The wiki's angle: Semux is an unrelated chain that used a Bitcoin-holder registration airdrop to find users.[2]

Design

The Bitcointalk thread, opened on 7 September 2017, says “Semux is a decentralized application platform, powered by the Semux BFT consensus engine” and lists a 30-second block time[1].

Airdrop

forkdrop's data file lists Semux as a registration airdrop at block 480000 on 2017-08-10, with no ratio, a maximum supply of 100,000,000 and the reason “Airdrop Over”[2]. Block 480,000 was mined on 10 August 2017[3]. The first post as edited in August 2019 does not describe the airdrop, so its terms are unverified[1].
