Limited Edition NFT for ChainX’s First Halving

3 min readApr 9, 2021


On May 25, 2019, the world’s first Digital Asset Cross-Chain Gateway to support Cross-Chain Mining and the first Substrate-based chain in Polkadot ecology, integrated Bitcoin light nodes in a pure WASM virtual machine environment for the first time. The ChainX network appeared and PCX was officially born.

The total amount of PCX is 21 million with its issuance halved every two years using a BTC-like model. In the first cycle, 20% of issuance is owned by the genesis development team and used for continuous development funds. After the first halving, this is stopped, meaning all further PCX issuance is owned by the community. This way, the founding development team only controls 10% of the total issuance.

Currently, about 0.6% of the PCX issued every day is allocated to XBTC holders, called Cross-Chain Mining. The PCX mined by the user goes to vote for nodes to maintain the security of the ChainX network and is used for transaction fees. ChainX generates blocks every 6 seconds, so an XBTC transfer takes only 6 seconds. The handling fee is less than 0.1 cents, offset by the rewards from Cross-Chain Mining, effectively making transfers free. The throughput is able to reach 1000 TPS. When connected to Polkadot, this can reach as high as 100,000 TPS.

Why does ChainX issue a Halving NFT?

Since its inception, ChainX has had the same philosophy as the BTC community, creating a purely decentralized community. In the past two years, the development and progress of ChainX is inseparable from the support and construction of the community. In June 2021, ChainX will usher in its first halving. As the halving is approaching, in order to thank the community for its contribution to ChainX in the past two years, a Halving NFT will be launched.

ChainX NFT Type Quantity

There are only 100 ChainX Halving NFTs worldwide, with a total of five types. Among them, the Node Recognition NFT, limited to 10 pieces, used to thank the outstanding nodes that have contributed to the ChainX network; the Community Recognition NFT, limited to 35 pieces, used to thank community members who have made important contributions to the ChainX community; Partner NFT, limited to 35 Pieces, used to thank excellent partners of ChainX; Halving Commemorative NFT, limited to 15 pieces, used to thank the community members who performed outstandingly in the Halving NFT release series; ChainX Design Master NFT, limited to 5 pieces, used to thank the designers who made the winning NFT.
