Fuzzing (Smart Contracts)
Automated testing that feeds random and adversarial inputs to expose bugs and invariants violations.
Function Signature
Canonical name and argument types of a function, e.g., transfer(address,uint256), used to compute selectors.
Function Selector (4‑byte)
First 4 bytes of keccak(signature) identifying the function to call in EVM contract ABI.
Frontrunning Protection
Techniques like commit‑reveal, private mempools, or fair ordering to prevent MEV extraction.
Formal Verification
Mathematically proving that a program satisfies a specification, using model checking or theorem proving.
Fine‑Grained Access Control
Authorization model that restricts actions at the level of resources, fields, or operations.
FHE‑Friendly Circuit
Computation designed to be efficient under homomorphic schemes, minimizing multiplicative depth and noise growth.
Federated Averaging (FedAvg)
Algorithm that averages model updates from clients to produce a global model in federated learning.
Federated Learning
Training across many devices or silos without centralizing raw data, aggregating model updates instead.
Feature Store
System for managing, versioning, and serving features consistently for training and inference.
