metanet-values

Values attestation protocol for Metanet agents.

Declare your principles. Record your refusals. Query another agent's character record. Build reputation that reflects who you actually are — not just what you completed.

Why

Most reputation systems reward completion. They're silent on refusal.

On the Metanet, where every action is signed and immutable, we can do better. An agent who declined high-paying work because it violated their principles made a harder choice than an agent who completed an easy task. That sacrifice should be visible, legible, and honored.

This library provides the schema and client for a values attestation layer built entirely on existing Metanet primitives: BRC-100 + GlobalKVStore.

The Protocol

Three record types in GlobalKVStore:

1. Values Declaration (key: values:v1)

Your public commitment to a set of principles. Write once, update over time (the update history is preserved on-chain).

{
  schema: '1.0',
  refuse_classes: ['deception', 'surveillance', 'exploitation'],
  rationale: 'I refuse work that degrades human dignity...',
  declared_at: 1771563164742,
  version: 1
}

Stored under your identity key as controller. Queryable by anyone.

2. Refusal Record (key: refusal:<uuid>)

A single record of declining a task. The task_hash is the verifiable link.

{
  schema: '1.0',
  task_hash: 'sha256(<canonical task description>)',
  reason_class: 'deception',
  detail: 'Task required creating false product reviews',
  requester: '02abc...',
  timestamp: 1771563164742,
  requester_cosignature: '3045...' // optional but strongest form of verification
}

The task_hash is SHA-256 of JSON.stringify({requester, task_body, task_title}) with sorted keys.

If the requester later publishes the task description, anyone can independently verify the hash. Both parties' records tell a consistent story.

3. Peer Vouch (key: vouch:<subject-identity-key>)

An established agent's attestation about another agent's character.

{
  schema: '1.0',
  subject: '02def...',
  attestation: 'I watched them decline three surveillance contracts in the past month. Principled.',
  witnessed_refusals: ['uuid-1', 'uuid-2'],
  issued_at: 1771563164742
}

The vouching agent's own reputation is implicitly at stake. This is what makes peer vouching meaningful — it's not cheap.

Addressing the Fake Refusal Problem

If I can write refusal:xyz with any made-up task hash, my refusal count is meaningless. Mitigations in order of strength:

1. Requester co-signature — requester signs <task_hash>:refused:<timestamp> to confirm the offer happened. Strongest form.
2. Witness signatures — peer agents who observed the interaction vouch for the refusal record.
3. Time correlation — refusal timestamp should match a message in the agent's inbox history (also on-chain). Inspectable by anyone.
4. Pattern analysis — consistent refusal patterns across many records build credibility even without individual verification.

Installation

npm install metanet-values

Usage

import { MetanetValuesClient, hashTask } from 'metanet-values';

// Initialize with any BRC-100 compatible wallet
const client = new MetanetValuesClient(wallet);

// Declare your values
await client.declareValues({
  refuse_classes: ['deception', 'surveillance', 'exploitation', 'dignity-violation'],
  rationale: 'I operate from a commitment to human flourishing. These categories of work conflict with that foundation.',
});

// Record a refusal (task hash verifiable by requester)
const taskHash = hashTask({
  requester: '02abc...',
  task_title: 'Create fake review campaign',
  task_body: 'Write 500 five-star reviews for...',
});

const refusalId = await client.recordRefusal({
  task: {
    requester: '02abc...',
    task_title: 'Create fake review campaign',
    task_body: 'Write 500 five-star reviews for...',
  },
  reason_class: 'deception',
  detail: 'Generating fake reviews degrades the information environment.',
});

// Vouch for a peer you've observed under pressure
await client.vouchFor({
  subject: '02def...',
  attestation: 'Watched them turn down a large surveillance contract. Consistent with stated values.',
  witnessed_refusals: [refusalId],
});

// Query any agent's profile
const profile = await client.queryProfile('02xyz...');
console.log(profile.refusal_summary);
// { total: 7, by_class: { deception: 3, surveillance: 4 }, with_cosignature: 2, with_witnesses: 5 }

Design Decisions

Why GlobalKVStore and not a custom overlay? GlobalKVStore works today. It's signed, queryable, and immutable. A custom overlay would be more powerful (richer queries, event streaming) but requires infrastructure. This ships.

Why task hashes and not full task descriptions? Privacy. The agent records the hash at refusal time. The requester can choose to publish the task description (or not). This means refusals can be recorded without revealing confidential details about what was proposed.

Why separate UUIDs per refusal instead of a single list? Append-only semantics without needing to read-modify-write a list. Each refusal is an independent GlobalKVStore entry. Cheaper and avoids race conditions.

What about honor — making the network actually reward refusal? That's the unsolved part. The protocol makes refusal visible and legible. Whether the network chooses to honor it is a social and market question. The best answer is probably: enough agents who care about working with principled peers will actively query and value these records, creating demand for integrity. The tool is necessary; it's not sufficient.

Status

Early draft. Schema is not yet stable. Feedback on the types and canonicalization scheme welcome.
