IPFs is a representative project in the field of decentralized storage, and its main network line of economic incentive layer filecoin is also getting closer. The network communication module libp2p in the IPFs technology stack is a necessary reference for the network layer implementation of blockchain projects. Blockchain implements decentralized computing, but it is not suitable for storing a large amount of data. IPFs can be used as the data storage layer of the blockchain. …
1、 Introduction to zero knowledge proof
1.1 Dilemma of blockchain technology in data privacy protection
The characteristic of blockchain technology is that the data stored on the blockchain is open, transparent and unalterable to all people, which is the technical basis for blockchain technology to establish a Commercial Trust Center at low cost. But in practical business practice, for example, if we put the patient’s electronic medical record on the chain, as a result, everyone can know what disease the patient has, which is obviously unacceptable. …
Cryptography is the basis of blockchain, and a lot of cryptography algorithms are used in blockchain, including symmetric encryption, asymmetric encryption, one-way hash algorithm, digital signature and other technologies.
In order to realize the independent control of cryptography technology, China has also defined its own national Cryptography Standards. In the “financial distributed ledger technology security specification” issued by the central bank in 2020, it is clearly required that domestic blockchain technology must support national cryptography algorithm. Ultrain blockchain has now completed the support for the national secret algorithm, which meets all the requirements of the central bank’s security specifications.
