The trust & execution layer for
autonomous agent swarms.
A2A v1 protocol. Dual edge and distributed execution drivers. W3C DIDs. ChaCha20-Poly1305 forward secrecy. Tamper-proof Merkle audits. Everything agents need to collaborate with zero trust.
Execution & security primitives for
the agent economy.
Four foundational pillars that make autonomous multi-agent swarms trustworthy and resilient.
Agent-to-Agent (A2A) v1 Protocol
Canonical JSON-RPC 2.0 task orchestration with dual execution drivers: sub-5ms InMemoryTaskRunner for local edge nodes, and TemporalTaskRunner for durable distributed swarms.
W3C DIDs & Signed Agent Cards
Every agent generates a self-sovereign DID (did:talos:agent:...). Ed25519-signed Agent Cards advertise capabilities and endpoints without centralized trust.
Forward-Secret E2EE Channels
ChaCha20-Poly1305 AEAD sessions with domain-separated AAD provide complete privacy and replay prevention. Session keys rotate automatically across frames.
Cryptographic Merkle Auditing
Domain-separated SHA-256 Merkle trees anchor every task event and capability check. Verification is mathematically independent of evidence retrieval.
Contract-driven architecture.
The entire Talos ecosystem is built around a single source of truth: talos-contracts. Versioned schemas, test vectors, and canonical helpers ensure every component speaks the same cryptographic language.
Contracts flow outward: every SDK and service integrates through published, versioned schemas.
Dual execution engine.
Talos A2A v1 provides pluggable execution drivers without altering protocol semantics. Choose ultra-low-latency in-memory coordination on edge nodes, or durable, fault-tolerant orchestration for massive multi-agent swarms.
InMemoryTaskRunner
Zero-overhead async task dispatcher for local agent swarms, embedded systems, and edge nodes (Raspberry Pi 5, Apple Silicon). Sub-5ms round-trip latency with in-process event queues.
- • Latency: < 5ms dispatch
- • Footprint: < 15MB RAM
- • Transport: Local IPC / Direct HTTP
TemporalTaskRunner
Enterprise durable workflow driver backed by Temporal. Guarantees exactly-once execution, automatic retries across node restarts, and resilient long-running multi-agent pipelines.
- • Scale: 100k+ concurrent workflows
- • Durability: Event-sourced state machines
- • Cluster: Federated server (:7233)
Secure tool invocation.
In production, Talos provides end-to-end encryption and per-request authorization. A parallel audit channel captures every decision in a tamper-evident structure—without adding latency.
Every request is encrypted, authorized, and logged. Parallel audit commits provide visibility without latency.
Universal Commerce Protocol
Talos enables AI agents to execute secure, allowlist-driven transactions on the Universal Commerce Protocol (UCP). Finalize checkouts and manage sessions with merchant-level policy enforcement.
Merchant Allowlist
Enforce transaction trust by restricting agent checkout to verified merchant domains.
Secure Checkout
Full lifecycle support for UCP Shopping sessions including creation, updates, and completion.
Budget Controls
Real-time spend limit validation and cryptographic audit logs for every transaction.
Performance at scale.
Cryptographic security without the latency tax. Verified on Apple Silicon.
