On Scaling and Accelerating Decentralized Private Blockchains

摘要

The increasing popularity of blockchain-based cryptocurrencies has made scalability a primary and urgent concern. Compared with the completely open, uncontrolled public blockchain system, private blockchain can provide better access control management. This paper proposes an architecture for distributed private blockchain. At the same time, we propose three strategies to improve the scalability of private blockchain: optimization of block construction, block size and time control optimization, and transaction security mechanism optimization. This system also redesigns the format of the trading, block structure and the way how system constructs blocks, makes it more suitable for the requirements of the private blockchain. From experiment results, we show that our system achieves better performance and scalability without compromising security guarantees.
