Huntercoin (ticker: HUC) was the first fully decentralized MMO, notable also for being among the first blockchain games to feature human mining and the first non-casino game to be provably fair. It was launched in 2014 by Andrew Colosimo.
Players competed for newly-minted coins on a peer-to-peer network by issuing transactions detailing their moves to the Huntercoin blockchain, which records the entire game map. The game is therefore turn-based, and due to scaling issues, its world was made relatively simple. The Crown of Fortune—which rewarded extra coins to its possessor—was the first NFT. As with Motocoin, it was eventually taken over by AI bots in a series of dramatic events.
Technically speaking, Huntercoin's blockchain is secured using proof-of-work. It was forked from Namecoin, and utilizes a similar data structure to account for player characters on its decentralized ledger. The team has since launched a successor blockchain called Xaya, which aims to solve Huntercoin's scalability issues and serve as a general platform (as opposed to a whole blockchain for just one game).
