Open Behavior Settlement Standard
X208 Protocol
A Code Symbol of a Technological Shift
Behavior Settlement Standard for AI & Web3.
Making actions verifiable, composable, and settleable.
// Value is no longer derived only from outcomes, but from actions.
What is X208
X208 is an open protocol standard for describing, authorizing, and settling behavior across AI agents, decentralized applications, and autonomous systems.
X208 is not:
- Not a payment system
- Not a financial product
- Not an application or platform
Why X208
- Behavior is becoming a new production factor.
- Existing systems can settle results, not processes.
- Behavior settlement must exist at the protocol level.
How It Works
Every action becomes a verifiable settlement event and produces composable outputs.
Core Capabilities
Behavior Settlement Events (BSE)
Canonical event structure for recording behavior-level intent and execution.
Context-aware Rulesets
Deterministic rules that bind behavior to context, policy, and constraints.
Dynamic Weight Engine
Configurable weighting across actors, signals, and execution paths.
Multi-path Settlement
On-chain, off-chain, and channel-based settlement primitives.
Composable Receipts
Receipts that can be referenced, chained, and reused by other systems.
Use Cases
Representative domains where behavior-level settlement becomes a protocol concern.
