Running the most diverse node fleet on XDC Network: 4 clients, 5 servers, 1 chain.
XDC is one of the few L1 blockchains with working Falcon signature code.
We have implemented and demonstrated NIST FIPS 206 Falcon-512/1024 post-quantum signatures integrated with XDC's XDPoS consensus — replacing ECDSA with lattice-based cryptography that is resistant to quantum computer attacks.

XDCIndia operates 4 independent XDC clients all syncing mainnet simultaneously — enabling true client diversity and reducing single-implementation risk.
| Client | Technology | Status | Latest Block |
|---|---|---|---|
| GP5 (XDC-Geth) | Go-Ethereum fork | ✅ Active | ~12.5M |
| Erigon-XDC | Erigon v3 port | ✅ Active | ~12.2M |
| Nethermind-XDC | .NET Nethermind port | ✅ Active | ~12.5M |
| Reth-XDC | Rust Reth port | 🔄 Syncing | ~12.5M |

Running 4 independent implementations of the same blockchain protocol is one of the strongest guarantees of correctness and resilience in distributed systems.
- No single point of failure — if one client has a bug, 3 others keep the chain alive
- Consensus validation — agreement across Geth, Erigon, Nethermind, and Reth proves block validity
- Client diversity — the gold standard in Ethereum post-Merge; XDC achieves it today
- Quantum readiness — migration is safer when multiple codebases can be upgraded independently
