Key terms and concepts used throughout the ORCAFI documentation.
AggregatorThe on-chain contract that receives signed data packages, validates them, and computes the final consensus price.Confidence ScoreA normalized metric (0-100) indicating data quality based on quorum strength, source reliability, deviation levels, and liquidity depth. Higher is better.Deviation ThresholdThe percentage price change that triggers an immediate update, regardless of the heartbeat timer. Prevents stale prices during volatility.HeartbeatThe maximum time allowed between price updates. Even if price doesn't change beyond the deviation threshold, a heartbeat update is forced.LWM (Liquidity-Weighted Median)An aggregation algorithm that weights prices by actual market liquidity, ensuring high-volume exchanges have more influence than thin pools.Oracle NodeA server running the ORCAFI client software, responsible for fetching off-chain data, validating sources, and participating in consensus rounds.QuorumThe minimum number (or percentage) of valid sources required to publish a price update. Typically 67%. Prevents single-source manipulation.Risk LevelA discrete classification (LOW, MEDIUM, HIGH, CRITICAL) assigned to each price update based on market conditions and anomaly detection.RoundA single aggregation cycle where data is collected, filtered, consensus is reached, and the final price is published on-chain.SlashingThe penalty mechanism where node operators lose a portion of their staked tokens for malicious behavior like signing stale data or deviating from consensus.Source RegistryThe on-chain contract that maintains the list of approved data sources, their types (CEX/DEX), reliability scores, and active/inactive status.TWAP (Time-Weighted Average Price)A price calculation method that averages prices over a time window, commonly used in DEXs to resist manipulation from single-block attacks.WadA fixed-point number with 18 decimal places, standard in Ethereum/Solidity. For example, 1.0 is represented as 10^18 (1000000000000000000).
