In the world of Web3, speed and security are just the beginning. To truly support a future filled with decentralized applications, you need a network architecture that’s modular, verifiable, and scalable at its core.
That’s exactly what U2U Network delivers — and it all starts with its Subnet Node Types: Master Nodes and Verifier Nodes.
🔷 Master Node: The Heart of the Subnet
Master Nodes are the backbone of every U2U Subnet. They handle the most critical roles in the infrastructure, ensuring stability and continuity. Their responsibilities include:
Transaction Management:
Master Nodes store and validate all transactions that take place within the Subnet. This ensures that each Subnet operates independently but with full data accuracy.
Data Availability Layer (DAL):
Acting as the DAL, Master Nodes ensure all decentralized applications within a Subnet have seamless access to reliable, verified data. This builds the foundation for trustworthy on-chain apps.
Cross-Network Operations:
Master Nodes bridge the Subnet and Mainnet. They submit and verify proofs, enabling smooth data transmission between protocols.
Rewards & Incentives:
By providing these essential services, Master Nodes receive a portion of Subnet transaction fees and rewards for proof submissions — making them not just a backbone but also an earning opportunity.
🛡 Verifier Node: The Guardian of Trust
If Master Nodes keep the Subnet running, Verifier Nodes keep it honest.
Built on TEE (Trusted Execution Environment) and FHE (Fully Homomorphic Encryption), Verifier Nodes validate the quality of service, accuracy of data, and ensure user privacy through:
Data Versioning & CRC Checks:
They track data changes and detect transmission errors to maintain network integrity.
Digital Signature & Hash Function Validation:
Verifiers ensure that all Subnet interactions are legitimate using cryptographic proofs like SHA-256 and MD5.
This dual-node design brings together performance (via Master Nodes) and provable integrity (via Verifier Nodes), creating an enterprise-grade, scalable, and secure Subnet model ready for any Web3 application.
