Overview

Randomized trial demonstrates improved transaction throughput and security in blockchain systems, suggesting a practical solution to the blockchain trilemma.

Key Points

  • This research aims to address the blockchain trilemma by enhancing transaction throughput while maintaining security and decentralization.
  • Proposed a novel storage architecture integrating Arweave's permanent data layer with an enhanced proof-of-access consensus protocol.
  • Conducted simulations on a multiphase global testbed with 25–112 nodes to validate the framework's performance.
  • Utilized transaction metadata compression achieving 7200 entries per megabyte for improved efficiency.
  • Achieved a baseline of 162 TPS, scaling up to 7200 TPS under optimal conditions.
  • Demonstrated a 99% reduction in annual storage growth compared to traditional systems, with Sui and Avalanche showing 5.3× and 3.5× storage efficiency respectively.
  • Established formal security guarantees through game-theoretic proofs, maintaining a chain quality of 0.82 under 40% adversarial presence.
