Summary

A peer-to-peer inference network that shards a model across consumer hardware. Transformer blocks are distributed by pipeline parallelism, hidden state tensors move over a low-latency mesh, and each contribution is settled against an on-chain attestation rather than an invoice.

Role in the stack

Supplies compute. Contributors earn against Proof of Contribution, verified off chain and anchored on chain.

Weights are content addressed

GGUF files are chunked by transformer block, hashed with BLAKE3 into CIDv1, and moved over a 64 MiB sliding window on libp2p request-response. No model host to take down.

Gradients, never data

Federated training uploads weight gradients only. Contributor data does not leave the contributor device.

Settlement conserves supply

Rewards are escrow funded. There is no mint and no inflation. The chain enforces eligibility, maturity, disputes, and refunds.

Architecture

  1. Request Funder escrows the reward
  2. Shard Layers assigned across the mesh
  3. Execute Hidden state over libp2p
  4. Attest Verifier-signed digest, Halo2
  5. Settle Chain-enforced maturity and dispute
One inference session from request to settled reward.

Specification

Values are taken from the protocol repository and from live chain parameters.
