Bitcoin Pizza (BPA)BPA
A fork at block 501,888 at the end of 2017, announced with a 1:1 airdrop and a planned later swap to a DAG chain at one to one billion.
The wiki's angle: Bitcoin Pizza borrowed Bitcoin's most famous meme for its name, promised a DAG future, and set aside 210,000 coins for itself — the pattern of most late-2017 airdrop forks in one thread.[3]

Announcement
The Bitcointalk announcement, opened on 12 December 2017, promised a 1:1 fork and then a swap to a DAG-based BPA at 1:1,000,000,000[3]. It listed Equihash, 120-second blocks and a cap of 21,210,000 coins, of which 210,000 were reserved for developers and promotion[3]. Whether the DAG chain was ever launched is unknown to this wiki[3].
