Zus Data Ledger

At the core of Zusama’s transparency layer lies the Zus Data Ledger, a Solana-compatible blockchain subsystem that manages contribution proofs, node scoring, and tokenized reward allocation.

1 Consensus & Verification

Zusama uses a Proof-of-Contribution (PoC) consensus model where:

• Each node submits encrypted computational proofs.

• Zusama validators verify the authenticity of contributions using Zero-Knowledge Proofs (ZK-SNARKs).

• Verified contributions are logged immutably on the ledger.

This process ensures that every data or compute contribution is verifiable, traceable, and non-repudiable without compromising user identity.

2 Smart Contract Functions

The ledger hosts a suite of smart contracts that autonomously manage:

• Reward Distribution: Allocation of $ZUS tokens based on PoA (Proof of Activity), PoC (Proof of Contribution), and PoI (Proof of Intelligence) scores.

• Node Ranking System: Evaluates long-term consistency and contribution quality.

• Governance Voting: Community-based upgrades for protocol evolution.

3 Economic Integrity

Each transaction and reward claim is executed under atomic smart contracts ensuring deterministic outcomes and eliminating double-spending risks. The integration with Solana ensures low-latency and cost-efficient microtransactions, critical for real-time AI node environments.
