Overview

Materios Partner Chain — Overview

Materios is a Substrate-based partner chain purpose-built for certified data anchoring and AI verification. It extends the Proof-of-Inference protocol with a dedicated execution layer optimized for high-throughput receipt storage, blob attestation, and multi-party threshold certification.

Why a Partner Chain?

Cardano L1 provides strong finality guarantees, but anchoring every individual AI receipt on-chain is cost-prohibitive at scale. Materios solves this by:

• Batching: Thousands of PoI receipts are collected, Merkle-hashed, and the root is periodically anchored to Cardano L1.

• Dedicated throughput: 6-second block times with lightweight blocks optimized for receipt and blob data.

• Threshold attestation: A committee of independent attesters must reach quorum before any batch is considered certified.

• Dual-token economics: MATRA (transferable, stakeable) and MOTRA (non-transferable capacity token with generation and decay) provide a fee model that doesn't require users to hold volatile assets.

Core Components

Component	Role
Materios Node	Substrate validator/full node. Aura block production + Grandpa BFT finality.
Cert Daemon	Attestation agent. Signs receipts, participates in threshold certification.
Blob Gateway	HTTP API for submitting and retrieving certified data blobs.
Anchor Worker	Bridges Materios batch roots to Cardano L1 metadata transactions.
Explorer	Web dashboard showing blocks, attestations, committee health, and chain status.

Consensus

• Block authoring: Aura (authority round-robin, sr25519 keys)

• Finality: Grandpa (BFT, ed25519 keys). Tolerates up to f faults where f = (n-1)/3 for n authorities.

• Session keys: Combined Aura + Grandpa keypair per validator.

Token Model

Token	Type	Purpose
MATRA	Transferable (12 decimals)	Staking, governance, transfers
MOTRA	Non-transferable	Capacity/fee token. Generated proportionally to MATRA balance, decays per block. Used to pay transaction fees without spending MATRA.

On-Chain Pallets

Pallet	Function
OrinqReceipts	PoI receipt storage, status tracking, content-based queries
Motra	MOTRA generation, decay, fee estimation, congestion pricing
Balances	MATRA transfers and account management
Grandpa	BFT finality (standard Substrate)
Aura	Block authoring schedule (standard Substrate)
Sudo	Governance (temporary, will be replaced by council governance)
