While Bitcoin developers debated arcane protocol rules, Counterparty got to work on building out its metaprotocol, and within a year of its launch was to spawn another first when it formed the foundation for Spells of Genesis, now regarded as the first blockchain-integrated game. This combined a trading card game with an arcade-style shooter, using the Counterparty protocol to tokenise its digital cards. The first onchain asset for the game, FDCARD, was issued on March 11, 2015, marking the birth of “true” digital ownership or what we now call NFTs.
