A daily crypto, finance, and AI vocabulary grouping puzzle for beginners.
DeFi Risk Primitives
These concepts explain how DeFi lending systems measure collateral quality, trigger liquidations, and account for losses.
- Oracle Heartbeat: An oracle heartbeat is the maximum allowed time between reference-price updates before a protocol treats the feed as stale or forces extra safety checks.
- Collateral Factor: A collateral factor is the percentage of an asset's value that a lending protocol allows users to borrow against, reflecting liquidity and risk assumptions.
- Liquidation Threshold: A liquidation threshold is the health boundary at which a lending position becomes eligible for forced unwinding to protect lenders from further collateral shortfall.
- Bad Debt: Bad debt is the unpaid liability that remains after collateral liquidation fails to cover what a borrower owes, creating a loss for the system or its backstop.
Macro Liquidity Signals
These terms describe how investors read funding conditions and benchmark government debt when assessing broader market liquidity.
Real YieldTerm PremiumDollar LiquidityTreasury Auction
- Real Yield: Real yield is the return on an asset after adjusting for inflation, making it a common benchmark for comparing nominal rates with actual purchasing-power outcomes.
- Term Premium: Term premium is the additional compensation investors may demand for holding longer-maturity bonds instead of rolling short-term debt, beyond expected policy-rate paths.
- Dollar Liquidity: Dollar liquidity refers to how easily banks, funds, and firms can obtain U.S. dollar funding for settlement, financing, and cross-border obligations.
- Treasury Auction: A Treasury auction is the process through which the U.S. government sells new bills, notes, or bonds, providing a live signal of demand and financing conditions.
Agent Runtime Ops
These terms cover the runtime building blocks used to ground model outputs, choose tools, and measure agent quality.
- Tool Calling: Tool calling is the pattern where a model selects and structures a call to an external function, API, or workflow instead of answering from text alone.
- Retrieval-Augmented Generation: Retrieval-augmented generation, or RAG, combines search over relevant documents with model generation so responses can use fresher or domain-specific context.
- Inference Router: An inference router is a system that directs a request to different models, hardware pools, or decoding settings based on cost, latency, or capability requirements.
- Eval Suite: An eval suite is a structured set of tasks, datasets, and scoring rules used to measure whether a model or agent meets quality targets after prompts, tools, or models change.
Crypto x AI Infrastructure
These concepts describe infrastructure layers used to coordinate compute, verify outputs, publish data, and settle activity across systems.
Decentralized GPU NetworkProof of InferenceData Availability LayerSettlement Layer
- Decentralized GPU Network: A decentralized GPU network coordinates many independent compute providers so workloads can be matched with available hardware through marketplace or protocol rules.
- Proof of Inference: Proof of inference refers to techniques for giving verifiable evidence that a specific model computation or output was actually produced by a claimed system.
- Data Availability Layer: A data availability layer is infrastructure that makes transaction or batch data widely accessible so participants can verify results and recover state when needed.
- Settlement Layer: A settlement layer is the base system where transfers, obligations, or rollup state updates become final, anchoring trust for higher-level applications.
