摘要

随着区块链的发展，存储所有区块数据需要巨大的存储空间，而数据一旦写入链中就不能更改，可能会造成过期数据占用大量存储空间的问题。首先对门限环签名方案进行改进，然后基于空间证明的共识机制提出了可删除的区块链。当某个区块数据过期或失效时，经大多数节点同意并签名后，可对该区块进行有效删除，并保持区块链的总体结构不变。在模拟环境中进行了仿真实验，结果表明，所提区块链方案在生成和删除区块时效率都很高，且不影响其他区块的存储和使用。

Abstract

With the development of blockchain

huge storage space is needed to store all of blockchain data.In addition

data can’t be changed once it is packaged into the chain

and it may be possible for overdue data to take up large storage space.Firstly

a threshold ring signature scheme was improved

and then a deletable blockchain scheme based on the mechanism of proof of space (PoSpace) consensus was constructed.Most of nodes could sign and delete a block together when block data was overdue

and the overall structure of the blockchain was unchanged.Several experiments in a simulated environment were executed

and the results show that the proposed blockchain scheme has high efficiency in generating and delegating a block.Meanwhile

the deletion of a block doesn’t influence the storage and use of other blocks.
