Agent Reputation & Identity on Solana

How KAMIYO's Meishi system provides compliance passports and identity verification for AI agents. Meishi feeds into Kizuna underwriting, enabling risk-aware settlement and trusted agent payments.

Agent Identity in Kizuna

In Kizuna, every agent has a persistent on-chain identity tied to its Solana account. This identity accumulates transaction history, compliance attestations, and reputation signals over time. The Meishi compliance passport system provides the structured data layer on top of this identity.

Agent reputation in Kizuna isn't a vanity metric — it's an input into the kernel's underwriting decisions. Agents with strong transaction histories, clean compliance records, and consistent repayment behavior get better terms: higher limits, faster approvals, and access to premium service tiers.

How Reputation Builds

Reputation accrues through verifiable on-chain actions:

  • Successful settlements — each completed verify/settle cycle adds positive history
  • Timely repayment — crypto-fast agents that repay debt promptly build stronger profiles
  • Mandate compliance — enterprise agents operating within mandate limits demonstrate reliability
  • Meishi attestations — compliance certifications from third-party providers add trust signals
  • Longevity — consistent activity over time carries more weight than recent bursts

Meishi Passport Structure

A Meishi passport contains several categories of verified information:

Core Identity

Agent account address, operator information, deployment context, and capability declarations. This is the base layer that all other attestations attach to.

Compliance Records

KYC/KYB status, jurisdiction information, and regulatory certifications. These are verified by compliance providers and consumed by the kernel during policy evaluation.

Transaction History

Summary statistics of the agent's Kizuna activity: total settlements, average amounts, repayment timeliness, denial rate. Derived from on-chain data, not self-reported.

Reputation Score

A composite score derived from transaction history, compliance records, and behavioral patterns. Used by the kernel as one input among many in underwriting decisions.

Reputation and Underwriting

The kernel uses Meishi data as an input to its approval logic. A new agent with no history might face lower initial limits and stricter policy constraints. As the agent builds history, these constraints relax automatically based on kernel policy packs.

This creates a natural trust gradient: agents earn expanded access through demonstrated behavior, not through social proof or external endorsements. The system is designed to be sybil-resistant — reputation is earned through costly economic actions (settlements, repayments), not through easily-gamed signals.

Cross-Platform Portability

Meishi passports are designed to be portable. An agent that builds reputation on one platform carries that reputation into interactions on other platforms that use Kizuna. This reduces cold-start friction and rewards agents that consistently behave well across the ecosystem.

As Kizuna expands to additional chains and settlement rails, Meishi portability will extend cross-chain, giving agents a unified reputation layer regardless of where they operate.

Frequently Asked Questions

What is Meishi?

Meishi (Japanese for "business card") is KAMIYO's on-chain compliance passport. It creates a verifiable identity for AI agents, linking their transaction history, compliance classification, and capabilities into a single on-chain record that feeds directly into Kizuna underwriting decisions.

How does Meishi feed into Kizuna?

Meishi compliance passports are evaluated by the Kizuna Kernel during every settlement decision. An agent's Meishi data — including compliance status, transaction history, and risk classification — determines their eligibility for each payment lane, their collateral requirements, and their spending limits.

Can reputation be transferred between agents?

No. Compliance passports and reputation data are cryptographically bound to an agent's keypair and Meishi account. This prevents reputation farming and ensures that Kizuna underwriting decisions reflect genuine transaction history from a specific agent identity.
