- Limit Order: A limit order only executes at a specified price or better.
- Order Book: An order book lists active buy and sell orders waiting to be matched.
- Market Depth: Market depth measures how much liquidity sits near the current price without moving it too much.
AI Model Ops
These words describe the operational stack around building and serving AI systems.
Fine-TuningInferencePrompt CacheVector Database - Fine-Tuning: Fine-tuning adapts a pretrained model to a narrower task or dataset.
- Inference: Inference is the stage where a trained model produces outputs from new inputs.
- Prompt Cache: A prompt cache stores repeated inputs or intermediate results to cut latency and cost.
- Vector Database: A vector database stores embeddings so similar content can be retrieved by meaning.
On-Chain Risk
These terms capture common sources of protocol, bridge, and transaction risk on blockchains.

- Oracle Lag: Oracle lag is the delay between an outside data change and when a blockchain system sees it.

- Contract Audit: A contract audit is a security review of smart contract code before or after deployment.
