An educational crypto, finance, and AI vocabulary puzzle about data plumbing, rate terms, serving speed, and collateral safety.
On-Chain Data Plumbing
These terms describe data feeds, chain indexing, query layers, and raw event records.
OracleIndexerSubgraphEvent Log - Oracle: An oracle delivers off-chain information, such as prices or events, to a blockchain application.
- Indexer: An indexer processes blockchain data into a form that is faster to search and query.
- Subgraph: A subgraph is a structured way to define and query indexed blockchain data, often through a Graph-style API.
- Event Log: An event log is a record emitted by a smart contract that can be indexed and searched later.
Yield Curve Basics
These terms cover yield, time sensitivity, return from holding, and relative price gaps.
YieldDurationCarryBasis
- Yield: Yield is the income or return generated by holding or lending an asset over time.
- Duration: Duration measures how sensitive a bond or fixed-income asset is to changes in interest rates.
- Carry: Carry is the return or cost of holding an asset position over time, often after funding or financing effects.
- Basis: Basis is the price difference between related instruments or markets, such as spot and futures.
Model Serving Ops
These terms cover response time, grouped requests, smaller numeric formats, and cached outputs.
- Latency: Latency is the time it takes for a model or system to respond after receiving a request.
- Batching: Batching combines multiple inputs so a system can process them together more efficiently.
- Quantization: Quantization reduces the precision of model numbers to save memory and speed up inference.
- Cache: A cache stores previous results so repeated requests can be served faster.
Trading Risk Controls
These terms cover posted collateral, maintenance buffers, forced close, and asset haircuts.
- Collateral: Collateral is an asset pledged to secure a loan or leveraged position.
- Maintenance Margin: Maintenance margin is the minimum collateral level a leveraged position must keep to stay open.
- Liquidation: Liquidation is the forced closing of a position when losses or collateral shortfall exceed allowed limits.
- Haircut: A haircut is the discount applied to an asset's value when it is used as collateral or measured for risk.
