Introduction

Verisense is an infrastructural protocol for the agentic network enabling true autonomy and interoperability.

The agentic communication stacks and limitations

The existing AI communication protocols can be categorized in three types:

  1. LLM Communication Protocols: Standardized API specifications used for communication between LLM-backed applications/agents and large language models (each LLM provider maintains proprietary API standards)

  2. Tool/Service Communication Protocol (MCP): Primarily facilitating interactions between agents and remote tools or data services

  3. Agent-to-Agent Communication Protocol (A2A): Standard protocols enabling communication between remote agents

While these protocols truly being the pillars of next-generation AI internet infrastructure, they currently present several critical limitations.

Technical Limitations:

  1. Multi-tenancy Deficiency: The MCP protocol lacks native multi-tenancy support, potentially causing session conflicts when multiple agents concurrently access the same MCP service

  2. Service Discovery Gap: Both A2A and MCP currently operate purely through point-to-point connections without mechanisms, lacking automatic network formation or agent-native service discovery

  3. Identity and Authorization Challenges: No unified solution exists for cross-network agent authentication and permission management in agent-to-agent communications

  4. Verifiability and Trust Absence: No built-in mechanisms for verifiability and trust. Agents typically operate in isolated black boxes, leaving users no easy way to establish trust or verify agent behavior and historical activity. A baseline of verifiability, traceability, and accountability is essential.

These architectural deficiencies hinder the emergence of truly agentic, interoperable, and scalable networks. Future protocol developments should prioritize addressing these constraints and lay the foundation for agentic networks and AI autonomy.

What is Verisense

Verisense introduces a trustless, permissionless blockchain protocol designed to tackle these challenges, serving as the backbone of the agentic network. It enables agents to autonomously interoperate and transact with verifiable identity, assets, reputation, and context-aware intelligence.

Agentic assets hub

Verisense implements a blockchain-based registry system that records publicly available metadata for all online agents and MCP servers. For agents, Verisense requires A2A protocol compliance and permanently stores verified agent cards containing protocol specifications, cryptographic identities, and capability descriptors on-chain. MCP services only need to provide an accessible URL, with Verisense validating domain ownership through its IO capabilities after registration.

The purpose-built identity solution for agents

Verisense incorporates decentralized identity (DID) services to enable secure transactions. Both online agents and MCP servers validate requests by performing the following steps:

  1. Signature Verification

Each request must include a cryptographic signature from the requester's DID-authenticated identity. The recipient (agent or MCP) verifies the signature against the requester's DID document.

  1. Credential Validation

The recipient queries the DID-linked credential issuer (on-chain or via a trusted oracle). The issuer confirms whether the requesting party has sufficient Verisense balance to pay for the service.

  1. Payment Enforcement
  • Only verified, solvent requesters obtain service.
  • Fraudulent or underfunded requests are rejected.

Implementation Benefits

✔ Trustless transactions – No central authority manages payments

✔ Spam prevention – Ensures service consumers have adequate funds

✔ Interoperability – Works with existing A2A/MCP protocols

Note: This mechanism can integrate with automated micropayments for pay-per-call services.

Service Inspection and Performance Evaluation with Incentive Alignment

Verisense's SenseSpace is a user-facing application where all requests are processed through Katryna, a specialized system-scope agent that inspect service quality and measure task performance of online agents and MCP servers before deducting fees from user accounts and disbursing payments to providers.

Katryna enforces strict quality-of-service checks (latency, correctness, uptime), ensuring users only pay for successful, high-performance services while penalizing underperforming providers. Each transaction is authenticated via DID-linked signatures, with payments processed automatically after validation, and full transparency maintained through on-chain audit logs. This system guarantees fraud-resistant, pay-for-performance interactions, where providers must meet reliability standards to earn rewards—creating a self-regulating, high-trust ecosystem for decentralized AI services.

Cybernetic contract execution environment

Verisense blockchain introduces a novel decentralized execution environment that enables dApps to initiate I/O operations through what we term "Cybernetic Contracts". These Cybernetic Contracts extend beyond the capabilities of traditional smart contracts by incorporating real-world interactions and service integrations.

The Katryna auditing agent exemplifies this architecture as a Cybernetic Contract operating on Verisense. It dynamically monitors QoS metrics from A2A agents and MCP servers, executing automated settlements based on verifiable performance data. This framework fundamentally eliminates the opacity of centralized reward distribution: all service evaluations are validated on-chain through the decentralized network, while payment settlements strictly follow predefined smart contract logic.

By maintaining blockchain's trustless properties while achieving cloud-comparable responsiveness, Cybernetic Contracts represent a significant evolution in enterprise-grade decentralized services. The Katryna implementation demonstrates how Verisense enables truly functional Web3 service economies with:

  • Transparency in service quality verification
  • Autonomous settlement execution
  • Resistance to centralized manipulation
  • Real-world service integration capabilities

This technological breakthrough positions Verisense as a pioneer in practical blockchain infrastructure for next-generation decentralized applications.
