A daily crypto, finance, and AI vocabulary grouping puzzle for beginners.
AI Agents
These terms describe how agentic AI systems break tasks into loops, use tools, and keep context.
- Tool Calling: Tool calling is when an AI system triggers external functions or APIs to fetch data or take actions as part of solving a task.
- Agent Loop: An agent loop is the repeated cycle of planning, taking an action (often via tools), and checking results until a goal is met.
- Planner: A planner is a component that turns a goal into an ordered set of steps, sometimes delegating subtasks to specialized tools or modules.
- Memory: In agent systems, memory is stored context (like notes or retrieved documents) used to stay consistent across multiple steps.
Stablecoin Design
These terms cover collateral models and basic mechanisms used to target a stable value on-chain.
OvercollateralizationAlgorithmic StablecoinMint and BurnRedemption Queue
- Overcollateralization: Overcollateralization means locking collateral worth more than the issued stablecoin or loan, providing a buffer against price moves.
- Algorithmic Stablecoin: An algorithmic stablecoin targets a stable value primarily through on-chain rules and incentives rather than direct asset backing.
- Mint and Burn: Minting creates new tokens and burning destroys tokens, changing total supply in response to deposits, redemptions, or protocol rules.
- Redemption Queue: A redemption queue is a mechanism that processes withdrawals in order when immediate redemption is limited by liquidity or rate limits.
Macro and Rates
These terms describe rate policy, inflation prints, and how bond yields can signal changing conditions.
CPIFed Funds RateYield CurveReal Yield
- CPI: CPI (Consumer Price Index) measures changes in the prices paid by consumers over time and is commonly used as an inflation indicator.
- Fed Funds Rate: The fed funds rate is the target interest rate for overnight bank lending in the US and influences broader borrowing costs.
- Yield Curve: A yield curve shows interest rates across different bond maturities, often used to discuss growth expectations and recession risk.
- Real Yield: Real yield is the return after accounting for inflation, often approximated as nominal yield minus expected inflation.
On-Chain Security
These terms describe common security patterns and attack surfaces without making any investment recommendations.
MultisigReentrancyOracle ManipulationAudit - Multisig: A multisig wallet requires approvals from multiple keys to execute actions, reducing single-key compromise risk.
- Reentrancy: A reentrancy bug can let an attacker call into a contract again before state updates, potentially draining funds if not protected.
- Oracle Manipulation: Oracle manipulation is when an attacker influences the data a protocol trusts (often prices), causing incorrect accounting or liquidations.
- Audit: A smart contract audit is a structured security review that looks for bugs, unsafe assumptions, and potential exploits before deployment.
