Slippage is a specific Markets coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: The difference between an expected execution price and the average price actually obtained. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Slippage is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Slippage describes how participants value, trade or obtain exposure to bitcoin. Market behavior can affect adoption and mining economics, but it does not rewrite consensus rules. Price evidence and protocol evidence answer different questions.
Understanding Slippage helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: slippage is the difference between an expected reference price and actual execution, arising from spread, market impact, latency, gaps and order priority; measurement needs side, timestamp, quantity and benchmark. They should be verified before using the coordinate in analysis.
The practical limit is: a market order does not guarantee the displayed price and a limit order controls price but not execution; simulated midpoint fills and average exchange quotes can understate real cost. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
