Semantic Substrate

What is Settlement?

SettlementThe final, irreversible resolution of an obligation between parties.

Settlement is the primitive that answers when is this truly done? It marks the point past which an obligation cannot be undone or revisited.

It is the layer where activity becomes final. Settlement closes the loop on a decision, giving every party certainty that the matter is resolved.

Where settlement sits in the stack

In the four-layer architecture of the agentic web, settlement is a Cross-cutting concept — it applies across every layer of the stack. See the thesis for how the layers compound.
