The XDC Network is a cutting-edge, open-source, delegated proof of stake consensus network (XDPoS). It boasts near-zero gas fees, 2-second block finality, and interoperability with ISO 20022 financial messaging standards. With its enterprise-grade architecture, the XDC Network is designed to support institutional use in trade finance and asset tokenization. It offers interoperable smart contracts, 2,000 transactions per second, and Ethereum Virtual Machine compatibility, providing a scalable infrastructure for both enterprises and independent community contributors.
