Abstract
Bardiel is a Virtual-native service agent that provides reliable and verifiable task execution, validation, and (where needed) arbitration for other agents.
It is built and operated by Virtual, and powered by Cortensor — a decentralized AI network that supplies redundant inference, Proof of Inference (PoI), Proof of Useful Work (PoUW), and reputation-based trust signals.
Bardiel does not perform heavy autonomous reasoning, and it is not a miner or base validator inside Cortensor. Instead, Bardiel acts as a smart client and oracle wrapper:
Receives tasks or claims from other agents (primarily Virtual GAME Workers/Functions, ACP flows, and, over time, ERC-8004 agents)
Delegates computation to Cortensor (Router → Session Queue → Miners → Validators)
Interprets PoI/PoUW and other trust primitives (redundancy, consensus, reputation, integrity, schema/spec checks)
Returns structured, agent-friendly verdicts back into the calling ecosystem
Bardiel exposes three primary capabilities:
Delegation-as-a-Service – Offloads tasks to Cortensor with explicit policies for redundancy, models, tooling, and validation tiers. Agents keep their “brain/logic” local, while Bardiel acts as an execution and verification layer: calling web/data/tools, dispatching heavy or parallel compute into Cortensor, and returning already cross-checked, verifiable results instead of raw completions.
Validation-as-a-Service – Acts as a second opinion or pre-/post-action check using PoI re-runs, N-of-M consensus, schema/spec enforcement, usefulness scoring, and safety templates. In Virtual, this is mostly pre-action validation (before ACP or other critical actions commit). For ERC-8004 agents, the same surface can be used both pre- and post-action via registry/validator flows when results need to be independently checked.
Arbitration-as-a-Service – Oracle-grade re-evaluation for disputes, primarily for ERC-8004 and other external agent marketplaces that wire Bardiel into escrow/settlement logic. In Virtual’s ACP, arbitration via Bardiel is optional and complementary to ACP’s own evaluators, not a replacement, and is reserved for cases where an additional neutral oracle is desired.
In practice, the high-level flow is always:
GAME / Agent decides → Bardiel delegates or validates → Cortensor computes and proves → Bardiel returns a verdict → Agent or marketplace continues.
Bardiel is not a new network. It is an agent-level product that turns Cortensor’s decentralized compute and validation primitives into:
a Virtual-first trust & execution service for Web3 agents, and
a ready-to-plug oracle / validator for ERC-8004 and other agent ecosystems that need reliable, verifiable AI task execution.
