QuarkBlockChain
Development Team: Formed by early enthusiasts of Bitcoin, the mainnet was launched on December 5, 2018, with the mainnet token being QKI (Quarkblockchain Integral), a total of 21 million tokens, and the circulating supply dropped to about 3.5 million after the fork in July 2019.
Technical Features: Provides solutions such as distributed Web, smart contracts, and enterprise blockchain integration, with an ecosystem that includes the QKFILE distributed storage system.
Token Use: QKI is used for on-chain transaction fees, and new coin production stopped after the fork, making the circulating supply scarce.
