Nowadays, with the continuous advancement of information technology, the world has officially entered the digital era. Digitization has played an important role in politics, economy, social governance and people's life. In judicial proceedings, the well-known types of evidence are also undergoing changes.

Problems encountered in judicial deposit

1. Data security and judicial admissibility are difficult.

2. Electronic evidence is difficult to obtain evidence, store evidence and authenticate

3. The credibility and authenticity of the evidence are in doubt.

4. Evidence is easy to lose.

5. Intellectual property rights holders are troubled by problems such as "plagiarism", "piracy" and "melting stem", so it is difficult to deposit, show and prove.

6. After the transformation of the Internet, the security risks of various electronic data and information have increased significantly, and users are easy to question or deny the online operation process and business handling behavior.

7. The professional skills and moral hazard of business operators also need to be greatly strengthened, and effective methods are needed to avoid to reduce legal risks.

8. Compared with other industries, the creditor's rights relationship involved in online banking business is more complex, and multiple contracts are often required to clarify rights and responsibilities. Therefore, the signing risks such as personnel identification, electronic signature and electronic seal involved are also very high.

How does the blockchain solve the problem of judicial deposit

The tamper proof and traceable technical features of the blockchain can realize the whole process of the client, inspection materials, appraisal process, appraisal report and other key business data, and effectively improve the credibility of the appraisal institution by further strengthening the openness and transparency of judicial appraisal behavior.



Blockchain technology has distributed ledger, tamper proof and mutual trust capability of multi node consensus, and data privacy can be protected through cryptography.



The multi-party linkage and credible trust mechanism and governance concept contained in the blockchain promote the scientization and convenience of the identification process from the level of legal scientific and technological means, so as to achieve more fair, economic and efficient legal services.



We can link the forensic case information, case handling step information, expert opinion information and other inspection data, make full use of the characteristics of blockchain decentralized storage, data tamperability, whole process trace and traceability, and effectively enhance the accuracy, authenticity and traceability of forensic data.



In judicial practice, electronic data is difficult to be authenticated in court, because it is easy to be tampered with and needs to prove that the evidence at that time is effective in various forms, so it is difficult to be recognized as evidence by the court. We can make use of the traceability, immutability, timestamp and other characteristics of blockchain to realize multi-party information sharing and transparent connection, and form a decentralized new trust mechanism, which can overcome the natural defects of "difficult evidence collection, easy loss and easy forgery" of electronic data, and can open up a large application space in the judicial field, Objectively, it also promotes the establishment of Internet trust system. Make the whole process of electronic data generation, storage, dissemination and use credible.



At present, the phenomenon of intellectual property infringement is very common in the current Internet era, and related disputes occur frequently. In the judicial practice involving intellectual property rights, the problems of difficult proof, high cost and low efficiency are very prominent. Blockchain technology can realize the solidification and permanent preservation of intellectual property rights through certificate storage. In case of disputes, users, judicial or arbitration institutions can obtain evidence directly from any node of the whole blockchain data chain, without the need for third-party institutions to issue certificates, which greatly improves the efficiency of relevant judicial rights protection work. Intellectual property rights are registered through the blockchain, which undoubtedly greatly facilitates the rights protection of owners.



Traditional evidence notarization requires users to go to the notary office and solidify the relevant data under the witness of the notary. Through blockchain technology, users can complete notarization and authentication online without leaving home through the Internet, eliminating the trouble of queuing up for notarization at offline notarial offices and effectively improving notarization efficiency. At the same time, users can also directly retrieve the data stored in the blockchain certificate through the Internet court, automatically perform hash verification, determine that the file has not been tampered with, and directly retrieve and use the blockchain certificate data as trusted evidence. Realize the pre deposit of blockchain certificates and automatic judicial verification, and effectively improve the efficiency of online litigation. After obtaining the complete data packet, the hash value of the data packet is written into the blockchain, so that the evidence can be tracked, traceable and can not be tampered with. In the process of data transmission, asymmetric encryption technology is used to encrypt, ensure transmission security, fully ensure the authenticity and security of evidence, and protect the privacy of the client. In the subsequent verification of data authenticity and integrity, it is completed by comparing hash values.



We can synchronize the electronic data generated by all online businesses of the bank (the whole process from user registration to final signing) to each node of the security chain, and store, preserve and supervise the electronic data through blockchain decentralization and distributed storage, combined with time stamps, consensus algorithms and other technical means, so as to retain the evidence chain throughout the business process, Form visual judicial evidence. The whole process can be traced, all data can be verified, and all links can provide reliable evidence, so as to ensure the security of bank electronic data and promote business compliance operation.

In case of contract breach, the electronic contract previously deposited can be used as evidence to quickly resolve disputes by using the three internet post loan disposal means of Internet arbitration, Internet empowerment notarization and Internet court. One click litigation and batch arbitration can be completed online, which largely avoids the above disadvantages and enables the online batch and efficient resolution of bank financial disputes. Thus, the bank's post loan disposal ability can be greatly improved, and a reliable contractual relationship and trust mechanism can be established between the bank lending platform and customers.

The electronic data certificate preservation based on blockchain technology ensures the authenticity, reliability and integrity of all electronic data in the process of enterprise operation, and ensures the non tampering of electronic data in all links, safe data storage, evidence retention and responsibility and right tracing. At the same time, it also provides later judicial rights protection services, Let every electronic data become electronic evidence eligible to go to court. When going online, the blockchain is used to ensure the originality and integrity of the deposit certificate data; After being linked to the chain, each judicial node on the security chain is used to ensure the credibility and security of data; In litigation, the evidence is directly connected to the Internet court to improve the efficiency of safeguarding rights.



For the deposit data, we can generate a unique corresponding digital fingerprint from the deposit subject, deposit time, deposit process and deposit content, encrypt and store it on the blockchain, and then synchronize it to each blockchain node on the security chain to prove who has linked a work at what time, so as to effectively ensure the integrity and judicial effectiveness of the deposit data.



The blockchain can establish an active defense risk management and control mode in judicial deposit, so as to provide low-cost and efficient legal services for digital asset dispute resolution and rights maintenance. 

Advantages of ULAM Technology

Completely go to the center
An end-to-end network composed of many nodes. There is no centralized equipment, management organization and intermediary. The rights and obligations of all nodes are equal. If any node stops working, it will not affect the overall operation of the system.

De trusting
All nodes in the system can trade without trust. The operation of the database and the whole system is open and transparent. Within the rules and time range of the system, nodes cannot deceive each other.

Reliable database
In the form of distributed database, all participating nodes obtain a complete database copy. The modification of a database by a single node cannot affect other databases unless more than 51% of the nodes in the whole system are modified at the same time.

Anti quantum attack
ULAM uses NTRU, a signature algorithm against quantum attack. NTRU(Number Theory Research Unit) algorithm is an open secret system invented by three mathematics professors of Brown University in 1996. This is a cryptosystem based on polynomial ring (where N is a security parameter). Its security depends on the shortest vector problem (SVP).

Disruptive innovation consensus
ULAM determines the mining probability according to the lucky value of the node, and there is no need to calculate the hash value. Each node determines the number of random numbers according to the lucky value. The greater the lucky value of a node, the more random numbers it has. The higher the probability of being selected as the accounting node each time the block is output

High TPS
The new non interactive transaction verification algorithm (NITCV) designed by Ulam can make the TPS as low as 10000. Ulam uses the method of knowledge proof to construct a non interactive transaction verification algorithm. When verifying a transaction in an ordinary blockchain, all miners need to verify the transactions in the block. Ulam's non interactive transaction verification algorithm generates a transaction verification certificate after the miners package the block and verify the transactions in the block.
