CCRMS — Cross-Chain Content Rights Management

MSc dissertation artifact at the University of Malta. CCRMS is a Polkadot parachain prototype that delivers subscription, pay-per-view, and permanent ownership as three native access modes of a single unified rights token — with automatic royalty splits and cross-chain portability via XCM and Snowbridge. All 11 KPIs met their targets.

The Problem

The content creator economy concentrates value in centralized intermediaries that retain 30–60% of gross creator revenue. Fragmentation runs deeper than fees: subscriptions live on Patreon, one-time sales on Gumroad, pay-per-view is economically unviable on conventional payment rails, and content rights remain bound to each platform’s terms of service. No existing system — centralized or decentralized — delivers all three monetization models from a single rights primitive portable across blockchains.

Architecture

CCRMS implements a pallet-first design on Polkadot’s FRAME primitives with parent–child NFT nesting on pallet-nfts. A single Content<T> storage entry simultaneously encodes subscription terms, pay-per-view quota, and ownership state; one integrated access check enforces all three — renewal and expiry are first-class state transitions, not contract-layer constructions.

• pallet-content-rights — full rights token lifecycle: minting, transfer, verification, expiry, royalty distribution with up to 10 collaborators at basis-point precision
• pallet-rights-verifier — Merkle storage proof verification for off-chain rights assertion without full chain sync
• XCM v5 + Snowbridge V2 — cross-chain portability with rights metadata preserved on transfer; Snowbridge V2 launched November 2025 with ~USD 75M TVL

The pallet-first architecture incidentally provided resilience when ink! development was discontinued in January 2026, demonstrating that the core system functions fully without a smart contract layer.

Results

Evaluated against a centralized Express.js/SQLite baseline with 56 unit tests, 7 performance benchmarks, a security audit, and a 10,000-iteration Monte Carlo creator revenue simulation:

• 26.2 TPS sustained throughput · ~6-second inclusion latency · 3–5-block cross-chain finality
• 191 bytes per content item · 90% baseline uptime · 15–20-second MTTR
• ~16.8% higher average creator revenue than centralized platforms (Monte Carlo mean)
• 8 security findings — 1 Medium and 1 Low remediated; 6 accepted as architectural trade-offs

The revenue advantage is strongly audience-dependent: creators above ~10,000 followers benefit decisively; those below ~2,000 are better served by centralized discovery platforms.

Key Finding

A unified rights token natively supporting all three access models can be constructed from standard FRAME primitives without novel cryptographic mechanisms. This closes a gap in the literature: no prior system had delivered subscription, pay-per-view, and permanent ownership as first-class modes of a single cross-chain-portable primitive.
