Decentralized Verification Network
AFXO operates a decentralized network of independent validators that verify every FX rate before publication. No single point of failure. No single source of truth.
How Validation Works
Every FX rate goes through a rigorous multi-step validation process before being published on-chain.
Multi-Source Ingestion
Each operator independently fetches FX rates from 10+ institutional data sources including central banks, market data providers, and liquidity venues.
Independent Validation
Operators run ML-powered anomaly detection and statistical validation on their data independently, flagging outliers and suspicious patterns.
Consensus Aggregation
Validated rates are submitted to the verification coordinator. A minimum of 2-of-3 operator agreement is required before any rate is published.
Confidence Scoring
The aggregated rate receives a confidence score (0-100) based on source agreement, data freshness, and historical consistency.
On-Chain Publication
Only rates meeting the minimum confidence threshold (70%) are published on-chain to Avalanche C-Chain as the canonical source of truth.
Currency Validation Status
Confidence scores and validation status for all 27 supported currencies.
This table shows representative validation data. Real-time updates (every 1-5 minutes depending on plan) are available via authenticated API. The page itself updates on deployment.

Operator Network
AFXO currently operates with 3 independent validator nodes. Each operator runs identical validation software but fetches data independently, ensuring no single point of failure.
Future: Community Validators
We plan to open the validator network to community operators who can stake tokens to participate in rate validation and earn rewards.
- Run your own validator node
- Stake tokens for validation rights
- Earn rewards for accurate validation
- Slashing for malicious behavior
Community validator program coming 2026. Join our mailing list for updates.
Security & Transparency
Every rate published by AFXO is fully auditable. We believe in radical transparency for financial infrastructure.
Multi-Signature Security
On-chain updates require multi-signature authorization. No single key can push malicious rates.
Full Audit Trail
Every rate update includes source data, timestamps, and confidence factors. Fully reproducible from stored inputs.
Rate Change Limits
On-chain contracts enforce maximum per-update change limits to prevent flash manipulation attacks.
