【摘要】 目前，建筑垃圾的资源化利用产业链条仍存在诸多问题亟需解决。借助于区块链技术，以绿色拆除为前提，充分利用区块链上数据的不可篡改、去信任化等特性，将拆除垃圾从出场、运输轨迹到入场收纳的整个过程进行了实时跟踪记录。将绿色拆除与区块链技术相结合，提高了工程管理的信息化层次，通过共识机制，杜绝了数据的随意篡改，增强了数据的可靠性和可信度，保证了拆除数据、建废运输路径及收纳数据的真实性。更多还原

【Abstract】 At present, there are still many problems to be resolved in the industrial chain of resource utilization of construction waste.With the help of blockchain technology and on the premise of green demolition,this article made full use of the characteristics of the data on the blockchain that can not be tampered with and trustworthy. The whole process of the demolished garbage from the exit,transportation track,and entry storage had been tracked and recorded in real time. The combination of green demolition and blockchain technology has improved the informatization level of project management. Through the consensus mechanism,the random tampering of data is eliminated,the reliability and credibility of data are enhanced,and the authenticity of demolition data,transportation path and collection data of construction waste is guaranteed.更多还原
