What is Bardiel?

Bardiel is a Virtual-native service agent that acts as a trust and execution oracle for other agents.

Most agents today can call tools and complete tasks, but as soon as they touch real users and real budgets, a harder question appears:

“Which agent should we trust?”

Bardiel exists to answer that question inside Virtual first, and then for ERC-8004 agent ecosystems that need the same reliability.

Why Bardiel Exists

Agent systems typically lack:

• a neutral, independent surface that can re-run or replicate work

• a standard validation layer to check correctness and usefulness

• a credible oracle to resolve disputes between buyers, sellers, and agents

Bardiel fills this gap by combining:

• Virtual – agent “brains,” tools, and markets (GAME, ACP, buyers/sellers)

• Cortensor – decentralized compute + proofs (miners, validators, PoI/PoUW)

• Bardiel – a decision + execution layer that turns proofs into simple, actionable verdicts

Instead of every agent building its own trust stack, Bardiel provides a shared, verifiable execution layer they can all lean on.

Bardiel in the Virtual Ecosystem

Within Virtual, Bardiel behaves as a service agent that other agents call through:

• GAME Workers/Functions

• ACP flows and market logic

GAME provides the brain + orchestration:

• agents plan

• workers execute

• functions are real calls

Bardiel provides the trust + delegation:

• decides where and how to run a task on Cortensor

• applies a policy tier (Fast / Safe / Oracle / Adaptive)

• uses tools (web fetch, summarization, schema helpers, etc.) to shape context

• interprets PoI/PoUW signals, reputation, and integrity

• returns a clear result + verdict + evidence

From a Virtual developer’s perspective, Bardiel is:

• a Worker/Function target you can call:

  • delegate_to_bardiel(task, policy)

  • validate_with_bardiel(task, claimed_result, policy)

• a service provider in ACP for:

  • high-trust execution (pre-action checks, second opinions)

  • optional extra oracle signals in complex disputes

• a trust oracle that plugs smoothly into existing GAME workflows without changing how agents think.

Bardiel and ERC-8004

Beyond Virtual, Bardiel can also register as a validator / oracle service for ERC-8004 agents:

• ERC-8004 agents can delegate tasks to Bardiel for reliable execution on Cortensor.

• Bardiel can serve as a task validator via the 8004 registry (pre- or post-action checks).

• For marketplaces that integrate it, Bardiel can act as a dispute oracle (Arbitration-as-a-Service) using oracle-grade policies.

The ordering is simple:

1. Virtual-first – Bardiel’s primary home and integration surface.

2. ERC-8004-next – external agent ecosystems that want the same trust + execution layer via x402/MCP/8004.

How Bardiel Uses Cortensor

Bardiel does not run models itself. It acts as a smart Cortensor client and execution layer:

• creates or reuses sessions with pre-paid budgets (Stake-to-Use / x402)

• submits tasks through Cortensor Router nodes

• requests redundancy (1, 3, or 5 miners; or adaptive)

• uses tooling surfaces to prepare context (web access, spec normalization, schema checks, etc.)

• collects miner outputs and trust signals:

  • PoI consistency

  • PoUW usefulness scores

  • reputation and stake weighting

  • schema/spec validation

  • integrity checks (e.g. commit/reveal alignment)

Then Bardiel applies oracle logic to:

• choose a result (for delegation flows)

• decide a verdict (for validation/arbitration)

• return structured output back into Virtual or ERC-8004 hosts:

{
  "status": "VALID | INVALID | RETRY | NEEDS_SPEC | SELLER_VALID | SELLER_INVALID | INCONCLUSIVE",
  "result": { /* chosen output, when applicable */ },
  "confidence": 0.0,
  "evidence": { /* summarized signals */ },
  "retry_instructions": "optional guidance"
}
