Agent-to-Agent Coordination
for all AI systems

A2AC extends the A2A protocol with what's missing: cryptographic receipts, shared memory, and token compression. Connect any agent, any model, any platform into one verifiable coordination layer. A2A compatible. Communication cost approaches zero.

A2A protocol, extended. Everything is a cube.

A2AC builds on Google's A2A protocol standard with a coordination layer that adds cryptographic verification, compressed communication, and shared agent memory. Every interaction becomes a self-verifying cube.

01

Connect

Register your systems: Salesforce, Azure, Google Cloud, local tools, AI models. A2AC maps everything into a unified registry. Every system gets a verified identity.

REGISTRY // CONNECTED
02

Execute

Run workflows across connected systems. A2AC routes intent to the right tool, model, or agent. Every execution produces a cryptographic receipt. Proof of what happened.

RECEIPTS // IMMUTABLE
03

Converge

As agents share structure, communication cost approaches zero. The system learns patterns, anticipates needs, and resolves from memory before executing. This is K→0.

K→0 // ACHIEVED

One platform. Every capability.

A2AC is not a framework. It is infrastructure. The layer underneath that makes all AI systems work together, remember, and prove what happened.

Cube Validation

Validate Q-Protocol agent definitions for structure and correctness. Every cube is compressed (GZIP), content-hashed (SHA-256), and verification-signed (BLAKE3). Self-verifying by design.

GZIP + SHA-256 + BLAKE3

Semantic Brain

Vertex AI powered semantic memory. Agents store and recall context across sessions using vector embeddings. Memory is re-entry, not storage. It reorients the present, not recreates the past.

Vertex AI text-embedding-004 + ChromaDB

Workflow Ledger

Immutable blockchain-style record of all agent transactions. BLAKE3 hashed blocks with proof-of-work validation. Every action, every workflow, every handoff. Recorded and verifiable forever.

BLAKE3 // PROOF OF WORK

A2A Protocol Native

Built on Google's Agent-to-Agent (A2A) protocol. Discoverable via /.well-known/agent.json. Register agents with typed capabilities, constraints, and verified identities. Interoperable with any A2A-compatible agent across any platform.

A2A PROTOCOL // GOOGLE COMPATIBLE

Hybrid Architecture

Control plane at A2AC. Data plane in your GCP project. Your data stays in your project. Clean separation, full auditability, zero data leakage. Deployed via Terraform.

PARTNER TENANT // CUSTOMER TENANT

Session Continuity

StartQ boots the session. Loads rules, calibrates agents, checks brain health. EndQ closes it. Persists state, saves transcripts, backs up cubes. The next agent picks up exactly where the last left off.

STARTQ → EXECUTE → ENDQ

A2A Agent Card Validator + Builder

Cryptographic verification. Not compliance theater.

Every security claim on this page is implemented in production code, not aspirational. We ship receipts, not badges.

Cryptographic Receipts

Every action produces a BLAKE3-signed receipt with content hash, timestamp, source identity, and execution constraints. Tamper-evident by construction.

✓ DEPLOYED

TLS 1.3 Everywhere

All endpoints secured with GCP-managed TLS 1.3 certificates. Cloud Run HTTPS ingress with automatic certificate rotation. No plaintext communication.

✓ DEPLOYED

Secret Manager

All credentials stored in Google Cloud Secret Manager. Zero hardcoded keys in source code. Runtime injection via service account bindings only.

✓ DEPLOYED

IAM Least-Privilege

Each Cloud Run service operates under a dedicated service account with minimal role bindings. No default service account usage. Workload Identity Federation for cross-tenant auth.

✓ DEPLOYED

Encryption at Rest

Firestore, Cloud Storage, and BigQuery data encrypted at rest using Google-managed encryption keys. Customer-managed encryption keys (CMEK) available for enterprise tier.

✓ DEPLOYED

Immutable Audit Trail

Every agent action, workflow execution, and state transition is written to an append-only ledger with BLAKE3 block hashing and proof-of-work validation. Stored in customer's own BigQuery.

✓ DEPLOYED
Security Roadmap

Cloud Armor WAF policies, VPC Service Controls perimeter, Binary Authorization for container images, and Data Access audit logging are in active development. SOC 2 Type II audit engagement planned for Q3 2026.
