The criminal's fingerprint can also be chained. Can the judicial alliance chain still tell you the truth?

Following the invoice chain, the judicial chain is about to enter the public life.

On March 30th, the National Internet Information Office released the first batch of domestic blockchain information service registration numbers. There are 197 blockchain information services from 18 provinces in the country. Among them, “True Network Technology (Beijing) Co., Ltd. The legal chain of the company's (hereinafter referred to as "truth technology") legal chain appears in the top ten list of the "inside blockchain information service filing list (first batch)".

On the afternoon of December 28, 2018, the Hangzhou Internet Notary Office, the first Internet notary office approved by the relevant departments, was established. The “Truth Technology” judicial alliance chain legalXchain and the Hangzhou Internet Notary Office jointly built the first blockchain in China. The distributed electronic evidence storage platform was launched simultaneously at the Hangzhou Internet Notary Office.

According to the official introduction of Truth Technology, legalXchain is a coalition chain based on the Hyperledger Fabric architecture for distributed applications in the judicial industry. It is mainly used in courts, judicial appraisal organizations and notary offices.

Hyperledger Fabric is one of the Hyperledger (superbooks) projects led by the Linux Foundation. The main code is contributed by IBM, Intel, and major banks. Hyperledger Fabric is designed to serve as the foundation for blockchain applications that develop modular architectures so that components such as consensus and membership services can be plug-and-play.

Solve the authenticity of data evidence information from the source

In fact, since the birth of blockchain technology, various "blockchain + XXX" collocations have emerged, and some of them are very "combined". Some companies have forced the use of blockchain technology to some of them. Decentralized industry. So what are the pain points in the industry in the blockchain + judicial combination?

At home, electronic evidence was originally used as audiovisual material, but with the popularity of the Internet, this definition clearly does not meet the actual needs of judicial practice.

According to public information, in 2000, the Shanghai Pudong New Area Court used e-mail as evidence for the first time in the judgment. This is the first case in which electronic evidence was adopted.

In the behavior of the Internet, the user's electronic data still has various problems at the time of generation, such as scattered or lost evidence; the evidence for the defense of rights is forged or falsified; the time of the electronic evidence is reset by the machine, resulting in the loss of legal effect of the information. The prosecutors have various obstacles in the process of defending their rights, and the process of defending their rights is very difficult.

The blockchain technology applied in the judicial field can solve the authenticity of the data evidence information from the source. Under the witness of the chain organization, the transparency, authenticity and traceability of the relevant data can make many disputes directly resolved between the two parties. If it cannot be resolved, after the lawsuit is brought to the relevant judicial department, legal persons can also directly judge by querying the information on the chain, reducing the number of unnecessary paperwork and intermediate collection procedures.

Data fingerprinting, multi-chain parallel consensus

It is reported that legalXchain can currently implement data fingerprinting, raw data is authorized to access on demand, and data security and sharing do not require a lot of coordination work. Not only that, the data on the chain enables fast tracking of data fingerprints, thereby tracking the criminal's crime time and location.

Under the centralized governance philosophy, the organization's data is run independently on its own independent server. The generation and consumption of data are controlled by the centralized server. The data cannot communicate with each other. If you want to share data between different platforms, you must perform “system docking” and access through API authorization. The development and maintenance costs are relatively high. High, data integrity and reliability cannot be effectively guaranteed.

legalXchain is based on the decentralized governance of the blockchain blockchain, providing the judiciary with the possibility of data sharing, allowing related node members to access in an authorized manner. Based on the legalXchain-based access control mechanism, the data owner can set Which objects can be viewed and which objects cannot be viewed to achieve different objects to see different data.

According to the legalXchain technical white paper disclosed by Truth Technology , legalXchain supports multi-chain coexistence. Each Peer node is connected to one or more channels of the consensus service, and an independent channel represents a “cell block chain”. This enhances the privacy of transaction data between certain organizations, and the "cell blockchain" can be broadcasted through nodes to enhance the sharing between the chains. The legalXchain uses an optimized BFT consensus protocol and P2P communication. Kafka provides sorting services based on Kafka. As shown in the following figure, the Order service provides a subject for the Peer node to subscribe to, and each topic is a channel. Peer can subscribe to multiple channels and can only access transactions on the subscription channel.

The entire sorting service includes Kafka clusters, ZooKeeper, Order server nodes, and each Peer node can connect to one or more channels of the consensus service. Transactions broadcast on the channel are written into Kafka by topic mechanism for the message mechanism, in order of consensus. Subscribe to the channel's Peer node to accept the encrypted block. Each Peer node can then individually verify the block and submit it to the ledger.

In addition, legalXchain also adopts a modular design to achieve loose coupling between modules by defining excuses between modules. The GRPC protocol is used between modules ( Odaily Planet Daily Note: GRPC protocol is a high HTTP2 protocol-based bearer released by Google. Performance, common RPC open source software framework ), abstract excuses, etc. are fully decoupled, and modifications within one module will not affect the functionality of other modules. In other words, developers can customize development according to their own needs, according to the needs of different users and scenarios, using different pluggable module components.

Covered 8 authoritative judicial nodes

According to Shi Song, Chairman and CEO of Truth Technology, LegalXchain currently covers IP360 (the Odaily Planet Daily Note: IP360 is a distributed application based on the legal chainchain of the autonomous blockchain network judicial alliance initiated by Truth Technology ). The eight authoritative judicial nodes, such as notary agencies, judicial appraisal institutions, and courts, are blockchain systems with a large number of nodes in the blockchain application. They are currently being applied in the legal industry. The user groups of services include legal technology. Companies, Internet companies, lawyer groups, judicial authorities, etc.

The Hangzhou Internet Court held that electronic data that is fixed by deposits and other technologies using blockchain technology should be comprehensively judged according to the relevant laws and regulations of electronic data.

The authenticity of some electronic data is likely to be “destroyed” at the time of the device or network environment before it was crawled, resulting in evidence that the evidence package is not credible.

Therefore, it cannot be because the technology such as the blockchain itself belongs to the emerging complex technology and rejects or enhances its certification standard, nor can it be reduced because of the difficulty of tampering and deleting the technology. Therefore, it is still necessary to dialectically treat the combination of “blockchain + justice”. Whether it can eliminate the false and wrong cases caused by wrong evidence in the future will take some time to practice and prove.
