Abstract: Redactable blockchains can modify on-chain data in a controlled manner, effectively overcoming the limitations brought about by blockchain immutability and providing a more flexible data storage scheme. This paper first studies the current mainstream redactable blockchain technology, sorts out and analyzes the existing redactable blockchain schemes, and divides them into four categories according to the ownership of the redactable blockchain, the validity of the redactable blockchain, the structure of the blockchain and the access strategy, and summarizes and analyzes the core ideas, advantages and disadvantages of each scheme. Then, the application of redactable blockchain is introduced in detail from the two fields of Internet of Things and identity authentication, and the advantages of redactable blockchain scheme are highlighted compared with other schemes. Then this paper analyzes the problems that need to be solved in the field of redactable blockchain, and discusses the development trend of redactable blockchain. Finally, the thesis is summarized.

Key words: blockchain, redactable blockchain, chameleon hash, decentralization
