Verifiable Randomness Comparison
See how TrueRandom compares to Chainlink VRF (single-node), Gelato VRF (shared drand beacon), and Pyth Entropy (two-party commit-reveal).
| Feature | TrueRandom | Chainlink VRF | Gelato VRF | Pyth Entropy |

Cost Model Pricing structure | Fixed subscription | $1-5+ per request | 10k free, then paid | ~$0.01-0.02 per request |
TrueRandom's Unique Position
Chainlink VRF: Single-node per request—cryptographic proof is verifiable, but operator could theoretically withhold results. Gelato VRF: Uses drand (16+ node threshold) for distributed randomness, but BLS signatures cannot be verified on EVM chains natively. TrueRandom: Combines dedicated committee control with on-chain verifiable BLS proofs.
What Makes TrueRandom Different
Built for applications where randomness integrity is non-negotiable—DeFi protocols, NFT platforms, and gaming requiring provably fair mechanics.
5-of-8 Committee Threshold
TrueRandom requires 5 of 8 dedicated committee members to sign each beacon, with on-chain verification. Unlike shared beacons (Gelato/drand) or single-node VRF (Chainlink), you get dedicated operators plus cryptographic proof verification on-chain.
BLS Threshold Signatures
Industry-standard BLS12-381 cryptography enables efficient signature aggregation. Partial signatures from committee members combine into a single compact proof verifiable on-chain.
Unlimited Derivations
Generate millions of random values from a single beacon using cryptographic expansion. Perfect for batch operations like NFT trait generation, tournament seeding, or game mechanics—without paying per value.
Dual-Tier Architecture
TrueRandom Beacon for on-chain DeFi/NFT applications with cryptographic proofs. TrueRandom Rapid for sub-100ms gaming and real-time applications via WebSocket—same security, different delivery.
What Makes Our Price Feeds Different
Built from the ground up for institutional requirements that existing FX and crypto oracles don't address.
Provenance Hash
Every AFXO price feed includes a cryptographic hash of the exact sources used to compute the rate. This enables full auditability—verify exactly which data sources contributed to any historical price.
100+ Assets Coverage
AFXO is the only oracle providing institutional-grade coverage for 100+ assets: 50 fiat currencies (including 23 African, 6 LatAm, 6 Asian) plus 50 major cryptocurrencies. Others focus on majors—we fill the gap.
Economic Intelligence
Beyond prices: volatility analytics, interest rate differentials, real-rate calculations, and quantitative metrics. Comprehensive data, not just price feeds.
Confidence-Aware Data
Unlike Chainlink, every AFXO feed includes a confidence score (0-10000 basis points). Your smart contracts can make risk-aware decisions based on data quality.
EIP-712 Signed Feeds
Industry-standard typed structured data signing. Verify signatures on-chain or off-chain with standard tooling. No proprietary formats.
AFXO Signed Price Feed v2
Every signed response includes comprehensive metadata for verification, auditability, and risk management. Standard EIP-712 format for easy integration.
- Deterministic feed IDs via keccak256
- Monotonically increasing rounds
- Configurable signature validity
- Chain-specific safety guarantees
