Circulating supply: ~19.9B XDC. Total supply: uncapped.
XDC uses XDPoS (Delegated Proof-of-Stake), with 108 active validator masternodes and 300+ candidates, each required to stake 10M XDC. The mechanism also incorporates a minor PoW requirement for block proposers to resist spam, alongside a Chained HotStuff BFT protocol for consensus finality.
XDC 2.0 upgraded consensus to Chained HotStuff BFT, cutting finality to 6 seconds (3 blocks), adding on-chain forensic monitoring that cryptographically identifies and slashes malicious validators. It also introduced a private subnet architecture for institutional deployments.
Use cases are concentrated in trade finance and RWA tokenization: TradeFinex tokenizes invoices, LCs, and bills of lading on-chain (integrated with major bank LC platforms).
Block time is 2 seconds, throughput exceeds 2,000 TPS, and transaction costs are near-zero.
