Structured Interchange Transfer Protocol

An open standard for verifiable, tamper-evident accountability. Every commitment dispatched, received, and resolved — cryptographically anchored and independently verifiable.

What is SITP?

Immutable ledger
Every staple anchored to a Merkle ledger with simultaneous Bitcoin, Ethereum, and timestamp authority verification.
Cross-enterprise federation
Route staples across company boundaries with bilateral ledger records on both sides. No single point of trust.
AI agent accountability
The trust layer beneath autonomous agents. Human-in-the-loop gates and auditable agent-to-agent commitments.
Public verification
Anyone can verify a staple record independently. No account required. Unauthenticated endpoint.

SITP operators

Thirteen operators. Fixed, load-bearing, and normative per the SITP Grammar Specification v1.0. Operators are verbs; parties, files, and amounts are the operands they take.

Operator Function
Parties
& Assignment The single owner who holds the baton. Answers "who owes this." A deadline may travel with the assignee.
&& Observer Receives the event stream. May overtake primary responsibility if the owner goes silent.
&&& Silent oversight An audit party hidden from the primary. Higher gravity than assignment or observation.
&@ Distribution A named group with a designated primary — a list that routes to one accountable owner.
Value and metadata
&$ Fiscal intent Marks monetary value moving with the commitment. Triggers payment, escrow, and compliance handling.
&# Metadata query A real-time query against commitment metadata.
Shape
+ Payload Attaches a file, URL, or clipboard reference to the commitment.
^ Urgency Level 1–5. The highest levels may bypass Do Not Disturb. At most one per staple.
* Project tag A project-namespace classifier. Organizes commitments into workstreams.
= Dependency References another staple this one waits on. Holds until the referent completes.
Runtime
% Progress A runtime completion signal, 0–99 percent.
! Blocker A runtime impediment or escalation flag — an event, not a level of urgency. An optional note may follow.
Capture
~ AI-invoke On-device compilation of natural language — typed or spoken — into canonical operators. The user confirms the compiled string before it is submitted.

Federation is an operand form, not a fourteenth operator: any party may carry an @domain suffix — &grenier@grenier.vendor — to reach a party on an independent SITP relay.

One line

Compose a staple in a single expression. Typeable in seconds, speakable, machine-generable.

Update the monthly sales funnel &jonathan(friday) +SalesFunnelBoDTemplate.pptx ^4 *sales-ops

Read aloud: Jonathan is the responsible party for updating the monthly sales funnel by Friday, using the attached board template, at urgency four, in the sales-ops workstream. The composer produces the string; the SITP Service interprets it into a signed commitment.
