The core of green technological innovation is to protect the ecology. The innovative introduction of ecological concepts into the existing ecosystem can ensure the sustainable development and progress of society. This paper mainly studies the path analysis of green technology innovation based on blockchain algorithm. Aiming at the high latency and low efficiency of pbft algorithm in green technology innovation, a low latency consensus algorithm ipbft based on an alternative voting mechanism is proposed. Explore the influencing factors of domestic realization of green technology innovation, clarify the reasons that hinder green technology innovation and give reasonable strategies to help domestic green technology innovation work to be carried out faster and better. This article compares the ipbft algorithm with the improved consensus algorithms cpbft, vpbft and pbft in recent years. Experimental results show that the consensus delay of the ipbft algorithm is much lower than that of the other three algorithms, and the average delay of the ipbft single consensus is only about 370ms. In different transaction volume and different node number throughput performance tests, the ipbft throughput in these two tests is better than the other three algorithms. In the view switching phase, the ipbft algorithm also takes less time than the other three algorithms. The above results show that the ipbft algorithm has lower consensus delay and higher throughput, which can reduce network communication overhead and save system transmission energy consumption. It can ensure the security and authenticity of information in the green technology innovation based on blockchain, and reduce system overhead.

绿色科技创新的核心是保护生态。将生态概念创新性地引入现有生态系统，可以保证社会的可持续发展和进步。本文主要研究基于区块链算法的绿色技术创新路径分析。针对绿色技术创新中pbft算法延迟高、效率低的问题，提出了一种基于替代投票机制的低延迟共识算法ipbft。探索国内实现绿色技术创新的影响因素，明确阻碍绿色技术创新的原因，给出合理的对策，帮助国内绿色技术创新工作更快更好地开展。本文将ipbft算法与近年来改进的共识算法cpbft、vpbft和pbft进行了比较。实验结果表明，ipbft算法的共识延迟远低于其他三种算法，ipbft单次共识的平均延迟仅为370ms左右。在不同交易量、不同节点数的吞吐量性能测试中，这两项测试的ipbft吞吐量均优于其他三种算法。在视图切换阶段，ipbft 算法也比其他三种算法花费的时间更少。以上结果表明，ipbft算法具有更低的共识延迟和更高的吞吐量，可以降低网络通信开销，节省系统传输能耗。
