A daily crypto, finance, and AI vocabulary grouping puzzle for beginners.
Restaking and Shared Security
These terms explain how restaking tries to extend economic security, and what can go wrong when trust assumptions change.
RestakingOperatorSlashingShared Security
- Restaking: Restaking is a design where staked assets (or staking commitments) are reused to provide economic security to additional services beyond the base network, typically with added conditions and risks.
- Operator: An operator is an entity that runs infrastructure (such as validators or service nodes) and performs duties on behalf of delegated stake, often under specific performance and availability requirements.
- Slashing: Slashing is a protocol-enforced penalty that reduces stake when a validator or operator violates rules, aiming to deter harmful behavior and enforce reliability assumptions.
- Shared Security: Shared security is an approach where multiple chains or services rely on the same set of economic guarantees or validators, which can improve bootstrapping but may couple risk across systems.
MEV and Orderflow
These terms describe how ordering affects who captures value and why users may seek protected execution paths.
MEVSandwich AttackPrivate MempoolOrder Flow Auction
- MEV: MEV (maximal extractable value) is the value that can be captured by controlling transaction inclusion and ordering in a block, such as through arbitrage, liquidations, or front-running strategies.
- Sandwich Attack: A sandwich attack is a form of MEV where an attacker places trades before and after a victim's swap to move the price against the victim and then capture profit when reversing.
- Private Mempool: A private mempool is a transaction relay path that avoids broad public gossip, which can reduce exposure to certain MEV attacks but also changes trust and censorship assumptions.
- Order Flow Auction: An order flow auction is a mechanism where searchers or builders bid for the right to execute or include a user's order, aiming to improve execution while explicitly pricing ordering privileges.
AI Agents and Evaluation
Evaluation and controlled tool use help teams improve reliability without assuming the model is always correct or safe.
Function CallingTool SandboxingEvaluation SuiteRed Teaming
- Function Calling: Function calling is a pattern where a model outputs a structured request to invoke a tool or API, separating reasoning from action execution and enabling more reliable integrations.
- Tool Sandboxing: Tool sandboxing restricts what an agent's tools can access or modify (for example via allowlists, timeouts, and isolated environments) to reduce the blast radius of mistakes or attacks.
- Evaluation Suite: An evaluation suite is a collection of repeatable tests and metrics used to measure a model or agent system across tasks, helping detect regressions and guide iteration.
- Red Teaming: Red teaming is adversarial testing that probes a system for failure modes such as prompt injection, data leakage, or unsafe actions, with the goal of improving defenses and procedures.
On-Chain Forensics and Compliance
These concepts describe common analysis techniques and rule checks used to manage compliance and operational risk.
Address ClusteringTaint AnalysisSanctions ScreeningTravel Rule
- Address Clustering: Address clustering is grouping blockchain addresses that are likely controlled by the same entity using heuristics, transaction patterns, or off-chain labels.
- Taint Analysis: Taint analysis tracks how funds move across addresses and transactions to estimate exposure to specific sources, noting that different heuristics can yield different results.
- Sanctions Screening: Sanctions screening is checking addresses, entities, or counterparties against sanctions and restriction lists to reduce regulatory and operational risk in compliant systems.
- Travel Rule: The travel rule is a compliance requirement in many jurisdictions to transmit certain sender and receiver information alongside qualifying value transfers, including some crypto transfers when intermediated.
