TessIndex: Capability Verified Identity System for the Agent Economy

TessIndex is Tesseris's research on persistent identity and capability verification for the agent economy. In this paper, Mehul Goenka, Tejas Pathak, and Siddharth Asthana propose an architecture connecting agent ownership, capability evidence, discovery, commerce, and economic reputation.

Abstract

Software systems have traditionally been organized around applications where human users act as principal decision-makers. Recent developments in agentic capabilities alter this paradigm: software agents now autonomously translate high-level goals into structured tasks, orchestrating tools, services and sub-agents to execute complex workflows. This evolution gives rise to an agent economy where these autonomous agents capture real economic value. However, the infrastructure required to support the agent economy fails across three critical dimensions: the absence of persistent identity infrastructure prevents systemic accountability in agentic workflows; capability claims remain self-declared not backed by verifiable execution evidence; and the disconnect between creator identities, agent performance, and project value hinders the economic valuation of agents as assets. While existing registries provide naming and discovery, unifying these features around a persistent identity anchor remains largely unaddressed. TessIndex is a capability-verified identity system for agent primitives that utilizes a dual-plane architecture: the blockchain records compact commitments for identity, ownership, and verification, while centralized servers maintain dynamic metadata for discovery, commerce, and reputation. It establishes: persistent identities across agent primitives to enforce systemic accountability in autonomous workflows; a predicate-based verification process replacing self-declared claims with cryptographic capability proof; an identity infrastructure that links agent performance to both project and creator identities while capturing value through tokenization. Ultimately, TessIndex serves as an integrated infrastructure that binds an agent's existence across capabilities, execution, and reputation into a single persistent identity.

The problem

The paper starts from a shift in software architecture: agents are moving from assistive interfaces into autonomous economic actors that can plan, call tools, coordinate services, and complete workflows.

Existing registries help with naming and discovery, but the paper argues that the harder problem is accountability. Agent systems need persistent identity, evidence for capability claims, and a way to connect performance back to creators, projects, and economic reputation.

The motivation is not only to find agents. It is to make an agent's identity durable enough that capability evidence, security posture, execution history, and commercial reputation can accumulate around the same accountable record.

Key contributions

  1. 1A unified identity architecture that combines compact blockchain commitments with richer registry metadata for discovery and operational use.
  2. 2Verification of claimed capabilities and security posture, with cryptographic evidence anchored to persistent agent identity.
  3. 3A registry schema that links commercial information, performance records, ownership, and creator identities to persistent agent records.
  4. 4Interoperability across protocols and registries through identity mappings, cross-registry resolution, and a federated trust model.

These are contributions of the proposed TessIndex system described in the preprint, not independently verified production outcomes.

Architecture and transaction lifecycle

TessIndex uses a dual-plane architecture. The blockchain plane records compact commitments for identity, ownership, verification, and tamper evidence. The registry plane stores dynamic operational information needed for discovery, commerce, routing, metadata updates, and reputation.

Outside the quoted abstract, capability-verified identity means the persistent record that binds an agent primitive to ownership, capability evidence, security posture, creator identity, and economic reputation. The architecture lets those claims update over time without losing the identity anchor.

  1. 1A creator or operator registers an agent primitive with a persistent identity and ownership commitments.
  2. 2Capability, security, and operational claims are attached to that identity as structured registry metadata.
  3. 3Predicate-based verification links capability claims to evidence anchored against the persistent agent record.
  4. 4Discovery and commerce use the registry plane while the blockchain plane preserves compact commitments and tamper evidence.
  5. 5Performance, verification status, and economic reputation accumulate around the same accountable identity over time.

Verification model and scope

The paper frames verification as predicate-based capability proof rather than a self-declared registry claim. A listed capability becomes more useful when it is supported by evidence that can be linked to the agent identity and inspected by counterparties.

This does not mean every agent record proves complete correctness, safety, or future behavior. TessIndex's verification scope is bounded by the claim being tested, the evidence attached to that claim, and the registry or protocol context where the identity is resolved.

From research to implementation

Readers can explore the product direction on the TessIndex product page. The current documentation explains what TessIndex is, its architecture, its workflow, and its core capabilities.

The research paper describes the published design and architecture. The product and documentation pages describe how Tesseris presents TessIndex inside the current platform. Those pages are related, but the paper should not be read as evidence that every described component is deployed in production today.

Scope and future work

The future work direction is to move from the proposed architecture toward deeper empirical validation, expanded interoperability, stronger verification workflows, and more complete economic reputation systems for autonomous agents.

Those items remain future work in the context of the preprint. This page does not claim benchmarks, adoption metrics, production guarantees, security certifications, audit results, or peer-reviewed acceptance that are not present in the paper record.
