Unibase DA++

Challenges with DAS

• Data security relies on the consensus protocol of DAS clients, which may reduce security compared to the Ethereum chain.

• High network transmission overhead with large data volumes.

Core Features

• On-Chain Verification:

  • Encode Proof: Verify RS encoding correctness on-chain.

  • Duality Proof: Ensure data availability within a specific timeframe on-chain.

  • Security assumptions: Relies on one honest validator for security.

• High Performance:

  • Supports large data writes with a speed of 100GB/s.

  • Fast proof generation offline, high encoding performance at 100MB/s.

  • Minimal impact on online verification, with challenges and verifications only triggered by false proofs.

• Infinity scalable:

  • Supports storage capacity above EB level.

  • Supports expansion to millions of storage nodes.

  • Supports custom private storage pools.

Decentralized, On-Chain High-Performance Data Availability Solution

• Decentralized Storage:

  • Users submit commitments and RS encoding parameters on-chain.

  • Blob size can be variable, and storage duration is customizable.

  • Data is encoded into multiple blocks based on custom encoding parameters and sent to different storage nodes.

• Decentralized Verification:

  • No DAC; storage nodes submit proofs on-chain for validation.

  • Encode Proof indicates that a storage node has stored a data block, which belongs to a specific part of the encoded user data.

  • Duality Proof demonstrates the continuous availability of data on storage nodes throughout its validity period.

• Cost-Efficient On-Chain Verification:

  • Aggregated verification with fixed-size Duality Proof reduces verification costs.

    • Proofs of data blocks from a single storage node are aggregated for verification on-chain.

  • Uses optimistic verification to minimize on-chain computational expenses.

    • Anyone can verify proofs offline and initiate on-chain challenges if discrepancies or missing proofs are detected.
