A January 2018 SegWit-enabled fork built around on-chain atomic swaps and hybrid proof of stake.

◆ Takeover vieweditorial · opinion, labelled

The wiki's angle: Atom pitched itself as an exchange-free swap coin, the opposite of the exchange-listing frenzy that most airdrop forks of its month depended on.[1]

Launch

According to its README, the Bitcoin Atom fork took place at block 505,888 on 24 January 2018[1]. Bitcoin block 505,888 has a header time of 24 January 2018, 14:26:41 UTC[2].

Design

The README describes a SegWit-enabled Bitcoin fork with on-chain atomic swaps using hash time-locked contracts and its own HTLC API[1]. It supports a hybrid consensus in which proof-of-stake block minting is enabled by default, letting holders earn transaction fees[1]. Its codebase is forked from Bitcoin Core and, per the README, kept in sync with it[1].
