The fastest growing & leading
L1 for global trade finance.
Measured live from rpc.xinfin.network — no marketing math. Total transactions estimated from on-chain block data; TPS from a 30-block sliding window.
Make XDC the most resilient and quantum-safe Layer-1 for regulated, real-world finance — ahead of the regulation, and ahead of the threat.
Two clocks are ticking. Most chains hear neither.
XDC settles trade-finance instruments — documents and value that must stay verifiable for 20 to 30 years. That long horizon turns two slow-moving risks into existential ones.
Clock 1 — Infrastructure debt
Single-client networks are one bug away from a halt. Legacy node software carries years of accreted state-storage and sync debt — bloated disks, slow RPC, heavy hardware. Every year on old foundations raises the cost and the risk of running the network.
Compounding · every blockClock 2 — The quantum threat
A cryptographically-relevant quantum computer breaks the ECDSA signatures protecting keys, bridges and signed documents. Adversaries harvest encrypted data now to decrypt later — so 30-year trade documents signed today are already exposed.
Harvest-now · decrypt-laterA multi-client network, on a modern foundation.
XDC is the first XDPoS chain with full client diversity — four independent implementations across three languages, live on mainnet. In parallel, we re-based the XDPoS engine onto pristine go-ethereum v1.17.3 (branch reset/integration-1.17.3), inheriting a decade of upstream engineering — with bit-exact consensus parity.
4 clients · 3 languages
go-ethereum (GP5), Erigon, Nethermind and Reth — Go, C#/.NET and Rust — all live on XDC mainnet. No single implementation can halt the chain.
geth v1.17.3 re-baseline
XDPoS layered additively onto current go-ethereum: path-based state (PBSS), Pebble, freezer/ancients, snap sync and the modern wire protocol — without touching consensus.
Bit-exact parity
Block production, RLP encoding, hashes, rewards and masternode economics are unchanged. A parity harness verifies identical state roots, receipts and block hashes against canonical chain.
Measured · modern-geth node vs legacy full node
Live readings from XDC mainnet production nodes — synced to head. Longer modern bar = better.
Quantum-safe before the deadline, not after the break.
The XDC PQ Initiative introduces XDSS-PQ — a post-quantum signature and key standard built on NIST-selected algorithms. We are mapping and migrating XDC's full quantum-exposed surface, prioritised by what cannot be re-signed later: long-lived trade documents.
The exposed surface
Trade document signatures
ECDSA · secp256k1 · 20–30yr lifespan
Validator masternode keys
ECDSA · secp256k1 · 108 validator keys
Bridge & DAO governance
ECDSA multisig · cross-chain · indefinite
P2P node communications
ECDH · TLS 1.2–1.3 · HNDL active now
The regulatory clock is already running
Financial entities must demonstrate robust cryptographic controls. XDC's bank partners are in scope today.
All new National Security Systems must be PQC-compliant on a fixed timeline.
Full PQC migration for EU critical infrastructure — including XDC's regulated partners.
ECDSA and all quantum-vulnerable algorithms deprecated from NIST standards.
We don't promise. We measure — in production.
A clear line of sight across both pillars.

H1-2026 milestones are shipped or measured; later milestones are the active plan.
The window and the work rarely line up. Right now they do.
The window is open
Regulation (DORA, CNSA 2.0, EU PQC) and infrastructure debt are converging on the same deadline. Whoever solves both first owns regulated, real-world finance on-chain.
The niche makes it existential
XDC's 20–30 year trade documents turn "someday" risks into today's problem — and turn solving them into a durable, defensible moat that generic L1s can't claim.
The proof is already in production
Four clients live. A modern node measured 3× smaller and ~40× lighter on CPU, bit-exact. This is an execution team that ships and measures — not one that promises.

quantum-safe future of trade finance.
