The First
Base Subnet
on Bittensor.

arctura-base-subnet bridges Base blockchain intelligence into the decentralized AI network. Miners attest to Base chain state. Validators score with Resonance BFT. TAO flows to proof.

Base subnets currently exist on Bittensor
128 subnet slots. Zero are dedicated to Base chain intelligence. First-mover in a category = durable advantage within the 4-month immunity period.

Daily active addresses on Base
Coinbase's L2 is the deepest onchain consumer surface in crypto. AgentKit, CDP SDK, and MCP tooling already deployed. Infrastructure waiting for an incentive layer.

TAO
Flows to miners who prove their work
Bittensor's cryptoeconomic incentive layer rewards verifiable AI work. Arctura's Merkle-anchored attestations make Base state claims provable on-chain — bad data earns zero weight.
How it works

Base chain state →
attested intelligence.

Miners read Base, prove what they read, and get paid in TAO. Validators enforce proof quality. No central oracle. No trust assumptions.

M
Mandate issuedValidator sends a BaseSubnetSynapse — block range, contract address, or agent action query — to all registered miners.
↓
R
Base RPC fetchMiner queries Coinbase's public RPC (or CDP SDK) deterministically. Same block in → same output out. Reproducible by any third party.
↓
P
Merkle proof builtMiner hashes the output, anchors it to the live Base block hash, and returns an attestation proof chain. Fabricated data fails the hash check.
↓
S
Resonance BFT scoresValidator verifies Merkle proof against live Base block hash. Scores 0.0–1.0. Sets Yuma Consensus weights. TAO flows to correct miners.

Base RPC Integration

Coinbase public RPC, CDP SDK, and AgentKit — all wrapped in a deterministic miner execution environment. Same state in, same proof out.

◈

Merkle-anchored attestations

Every Base state claim is hashed and anchored to a live Base block hash. Stale or fabricated attestations fail verification — zero weight, zero TAO.

⚡

Resonance BFT scoring

Four-dimensional validator scoring: attestation validity (40%), execution completeness (30%), latency (20%), confidence calibration (10%).

🤖

AgentKit mandate types

Miners can execute onchain Base actions — not just read state. First-class support for CDP SDK smart wallets and MCP tool bindings over Bittensor axon.

🌱

P5 Stewardship

Carbon-aware weight modifier. Miners declaring verified renewable energy receive +15% weight. Node weight reflects energy provenance, not only stake.

🔓

Apache-2.0 open source

Every line of code is public. Fork it, extend it, run your own validator. Built as a public good for the Base and Bittensor ecosystems.

Architecture

Six-layer signal stack.

The Arctura signal stack maps directly to Bittensor primitives. Each layer has a defined responsibility.

The subnet needs validators. Validators earn TAO. Infrastructure is ready. The only thing missing is you running a node.
