Data Integrity Mechanisms

IFÁ Labs implements multiple layers of defense to ensure that only accurate, high-quality price data reaches the onchain oracle contract. These mechanisms work together to prevent manipulation, errors, or bad data from compromising feed reliability.

1. Multi-Source Aggregation

Prices are never sourced from a single provider:

• Data is pulled from diverse, independent sources (major CEXs, DEX pools, forex gateways, regional exchanges).

• No single source can dominate or override the final aggregated value.

This diversity eliminates single-point failures and reduces the impact of outages or temporary inaccuracies on any one venue.

2. Outlier Detection & Filtering

During aggregation:

• Statistical analysis identifies prices that deviate significantly from the cluster.

• Outliers are automatically excluded before consensus calculation.

• Thresholds are tuned specifically for stablecoin behavior (tight tolerances for pegged assets).

3. Consensus Algorithm

The final price is derived using:

• Weighted median or weighted average, with higher weights assigned to more liquid and historically reliable sources.

• Median-based approaches provide strong resistance to manipulation even if several sources are compromised.

4. Zero & Invalid Price Prevention

Onchain safeguards (post-audit fixes):

• Submitted prices must be > 0 (validated before storage).

• Self-pairing (e.g., asset/asset) is blocked to prevent illogical 1.0 derived prices.

• Strict timestamp checks prevent redundant or stale submissions.

5. Decentralized Relayer Network

Updates are submitted by a decentralized set of relayers:

• No centralized operator controls price pushes.

• Future expansions include economic incentives and slashing for honest behavior.

6. Onchain Transparency

Every stored price includes:

• lastUpdateTime for verifiable freshness.

• Full data available via public view functions for independent validation.

Combined, these mechanisms ensure that IFÁ Labs feeds remain accurate, manipulation-resistant, and trustworthy — even in adversarial conditions.
