Overview

Randomized trial demonstrates improved data retrieval efficiency in blockchain, suggesting potential for enhanced applications.

Key Points

  • This research aims to improve blockchain data retrieval efficiency and security using Merkle Patricia tries.
  • Proposes a retrieval method using Merkle Patricia tries for blockchain data.
  • Constructs a global latest state index tree using users’ public keys.
  • Reconstructs transaction structure to enhance retrieval speed by including previous transaction data.
  • The proposed method significantly enhances retrieval efficiency.
  • Users can access both current and previous transaction information simultaneously.
  • Greater efficiency observed with an increasing number of transaction versions traced back.
