XKY Chain is a blockchain designed for religious charity. In the era of Internet 3.0, many physical assets will be digitized. Using blockchain technology to turn charity into a digital asset not only makes public welfare and charitable activities more transparent and credible but also encourages more people to participate in such activities. XKY Chain is the worlds first public blockchain for religious charity based on blockchain technology. It is a comprehensive system featuring distributed ledger on a public chain, decentralization, trustless traceability and anti-counterfeiting, free donations, and industrial payments. By leveraging the freedom, openness, and fairness of blockchain, XKY Chain ensures that all data related to the initiation, organization, fundraising, and use of charitable funds are publicly available and transparent. This enables global free flow of charitable information, optimizes the supply chain for religious charities, reduces costs, and achieves a high level of intelligent alignment between the global charity sector and the market through a specialized international industrial community and ecosystem.
