『二』Blockchain digital currency exchange platform construction solution

Digital cash exchange is an important role in the financial field The focus of competition. Having a good digital currency exchange has a great advantage in the competition among peers. The market of digital cash exchanges is a global market, involving world-wide trading business hosting platforms. Digital cash exchanges have various advantages due to various The data is different, the customization needs are different, and the functions are also different. A good digital cash exchange platform is rich in functions, secure in performance, powerful, and differentiated among similar products. Blockchain digital asset exchange technology development

Digital The unique interface of the cash exchange can provide customers with convenient fund transfer methods, such as quick recharge, currency withdrawal, currency recharge, etc. It can also support multiple transaction methods, currency transactions, legal currency transactions, over-the-counter transactions, etc. .

1. Off-site exchanges: Off-site exchanges are also called OTC trading markets. This is a place with no fixed place, no fixed rules and regulations, and no prescribed trading products. Users can achieve two-way transactions on off-site exchanges. , transactions are very free, and like other blockchain applications, there is no unified trading system and mechanism for remote exchanges

2. Currency transactions: Currency transactions, as the name suggests, are between digital currencies and digital currencies. Transaction, using currency as the unit of evaluation to purchase other currencies, and intermediary according to price priority and time priority.

3. French currency transaction: French currency transaction can be said to be the most direct way. Digital Cash Talk Bench What is the target price? A direct purchase transaction by a user with fiat currency is a French currency exchange. The disadvantage of French currency exchange is that the currencies that can be purchased are limited.

『三』 The Beijing Internet Court and the blockchain evidence storage system "IP360" have achieved seamless connection

Recently, the IP360 platform evidence has been connected with the Beijing Internet Court litigation platform. The submitted evidence can be submitted after providing evidence through the IP360 platform Beijing Internet Court Platform.

On the afternoon of September 25, the Dongcheng District Court of Beijing made a judgment on the case of JD.com infringing the right to network dissemination of information on the works of the Chinese Online Digital Publishing Group. In this judgment, the court adopted the IP360 forensic data evidence provided by Zhenchen Technology, confirmed the legal validity of the electronic data stored using blockchain technology, and clarified the review and judgment method for electronic evidence stored in the blockchain.

This is the first time that the Beijing Dongcheng District Court has made a judgment on an intellectual property case based on blockchain evidence, which has aroused widespread concern from the public and also laid a good foundation for the completion of the docking with the Beijing Internet Court. Base.

But nationwide, this is not the only case in which “blockchain + certificate storage” has been recognized by the court.

Subsequently, on September 7, the Supreme People's Court issued regulations on several issues in the trial of Internet courts. The regulations clearly state that “the electronic data submitted by the parties shall be authenticated through electronic signatures, trusted timestamps, hash value verification, blockchain and other evidence collection, fixation and anti-tampering technical means, or through electronic evidence collection and storage platforms. If it can prove its authenticity, the Internet court should confirm it.”

With the establishment of Internet courts in Hangzhou, Beijing, Guangzhou and other places, the blockchain evidence storage system is undoubtedly an important part of the construction process of Internet courts. The biggest highlight. In the case where traditional electronic data itself is easily tampered with, blockchain, as a "distributed storage technology", has the characteristics of irreversibility and non-tampering. Through blockchain smart contracts, business rules are abstracted into digital contracts and embedded in blockchain for execution. , and can be verified, ensuring that every step is carried out strictly in accordance with the pre-set process, thus ensuring the authenticity of electronic data. In the case where Chinese Online won a lawsuit against JD.com for the right to disseminate information on its work information network, it was through online evidence collection through the blockchain evidence storage system "IP360". It is understood that the system is based on the certificate storage and confirmation platform independently developed by legalXchain, a judicial alliance chain owned by Zhenchen Technology. Cooperating with the Ministry of Public Security, judicial appraisal, notary offices and other institutions, the review and identification of electronic evidence can be completed online, greatly improving the efficiency of litigation..

Compared with traditional litigation methods, "blockchain evidence storage" is undoubtedly a huge progress. With the continuous upgrading of blockchain technology, future litigation resolution will only be more fair and efficient.

『四』The meaning of digital identity in the blockchain (with an excellent blockchain article that triggers thinking)

As the infrastructure and connector of the current Internet, WeChat has The value of the Internet is based on "connection", the connection between people, the connection between people and money, the connection between people and things. Now it can also be the connection between people and things (scan the code of Mobike mini program to ride a bike), but all "connections" "The premise is that I trust WeChat, I trust Tencent, I trust the legal regulation of the Internet, and I trust that everyone around me is using WeChat. The root cause of this trust is trust in centralization, trust in companies with good reputations, and trust in institutions. , the rule of law, and community trust.

Nowadays, the blockchain seems to be able to turn each node in the blockchain network into a "WeChat". In order to form this kind of decentralized trust, we need to define a unique identifier for the node "WeChat". Trust the digital identity. This digital identity is not only the private key for managing your own digital assets in the blockchain network, but also allows this digital identity to ultimately serve real life and implement application scenarios. Therefore, it also needs to be endowed with prerequisites. The credit label of the legal system, institutions and communities.

The future world is distributed, and each node is verifiable and trustworthy. Whether placed in the blockchain or in the real world, each node becomes a "WeChat" trusted by all of us. , and at the same time, we ourselves can also become “WeChat” trusted by others.

1. Ship of Theseus - How to define yourself

In life, we often use Regarding identity, we often introduce ourselves to others. Sometimes we give out our business cards, and sometimes we show our ID cards. However, many people may not know what the meaning of identity is and how to define it.

There is a famous thought experiment called "The Ship of Theseus". The Ship of Theseus can sail uninterruptedly on the sea for hundreds of years. If a plank rots, a new plank will be replaced until there is a plank. One day, all the planks on the ship were not the original planks. So was the ship still the original ship of Theseus?

The human body is like the ship of Theseus. Cells are always undergoing metabolism. So all the cells have been renewed. Are you still the same person? What if your thoughts and personality also change?

Therefore, how to define yourself does not seem to be a simple matter.

2. Identity in life

In life, we have many identities. For example, in a company, you have your own position.In a family, it may be a husband, wife or child. For the bank, you are its customer. For your house, you are its owner. For your car, you are the landlord. car owner.

So we found that in different scenarios, you have different identities, and different identities usually correspond to different objects. For a bank, what it cares about is whether you are its customer. It doesn’t matter what role you play in the family. For a car, as long as you have its key, you can start it. Whether you are the landlord Don't care.

3. Define identity

Based on the previous discussion, I try to define identity:

Identity is the identifier of relationship,

Relationship is Bidirectional,

A relationship represents the rights and obligations between the parties.

So you have different relationships with different objects, you have different rights and obligations, and you have different identities.

For the country, you have citizenship, which is usually represented by an ID card. Citizenship means that you have the obligation to pay taxes and that you have the right to vote in elections. To the bank, you are its customer, representing your deposits and liabilities with it. For blockchain, you master the private key, which means you own the assets controlled by the private key, and the private key is your identity.

Therefore, we should not abandon the object and explore identity. What is important is not who you are, but who you are in the eyes of others.

In the process of using identity, there are two processes: authentication and verification. For example, after a Chinese is born, he has to go to the police station to register his household registration. This is the authentication process. After that, presenting his ID card is the verification process. Registration and login of accounts on the Internet are identity authentication and verification processes. The certification and verification of asset ownership in the blockchain is achieved through a consensus algorithm, which can be simply considered to be 51% voting approval.

4. Trusted data

Satoshi Nakamoto wrote a sentence in Bitcoin’s genesis block: “The Times 03/Jan/2009 Chancellor on brink of second lout for banks", this sentence was the front page headline of The Times that day, meaning "the Prime Minister saved the banks from the brink for the second time".

Many people believe that this sentence proves that The Times must have published this article that day, reflecting the existence proof capability of the blockchain.

However, the blockchain can only ensure that the written data cannot be tampered with, but cannot guarantee the authenticity of the data. The reason why we believe that this newspaper article must exist is because it was Satoshi Nakamoto who wrote the blockchain, and the authenticity of the data is guaranteed by Satoshi Nakamoto’s credibility.

In fact, the authenticity of data is generated in two ways:

Decentralized approach, or 51% democratic voting. For example, the authenticity of Bitcoin transaction data is actually guaranteed through 51% computing power voting. When off-chain data is uploaded to the chain, it can also be manually The voting method ensures the authenticity of the data, such as the decentralized prediction platform Augur.

However, not all consensus can be reached through majority rule.

For example, whether a work of art is authentic or fake must be authenticated by experts, but cannot be determined by the majority. The credibility of the appraisal results is guaranteed by the credit of experts. Whether a person is Chinese or not is verified by the police station when registering for residence, not by a vote of all Chinese people. Therefore, for specific scenarios, sometimes it is necessary to confirm the authenticity of the event through recognized authorities.

Normally, data native to the chain, such as token distribution, transactions and other data, can be easily reached consensus through a minority-subject-majority voting mechanism. However, when off-chain data is uploaded to the chain, its data Authenticity relies on the identity and reputation endorsement of the person on the chain, and sometimes legal means are needed to deter fraud through accountability mechanisms.

5. Trusted data uploading to the chain

Therefore, for the uploading of off-chain data, the authenticity of the data can be completed through the vote of a minority subject to the majority or the credibility endorsement of an authoritative identity.

The basic process of uploading trusted data to the chain should be as follows:

First, you need to have a digital identity. The authentication of this identity may be generated by 51% of the votes. It may also be through authoritative certification.

Then when the data is uploaded to the chain, identity information needs to be attached.

After obtaining the data, the data user verifies the identity information, and then determines the credibility of the data based on the verification results.

6. Identity management

When we use network applications, we need to register and log in to our account. Sometimes, for convenience, we will use third-party applications to register and log in. This Although the identity hosting method provides convenience, third-party applications can actually log in to the application without our authorization, perform operations, and obtain personal data.

So ideally, we want to be able to balance convenience and security. We want to be able to log in to different applications through the same account and be completely controlled by ourselves.

Digital identity can be roughly divided into three categories:

Digital sovereign identity, manifested in ChinaThe formula is CA certificate, EID and other solutions. To meet government supervision and be compatible with national laws, the sovereign identity must be known.

Digital network identity, that is, the login account of various APPs

Digital asset identity, that is, the address and private key of various blockchain assets

Digital identity Management applications should be compatible with these identities and be able to implement identity authentication, verification, logout, loss and retrieval, etc.

There should also be a data management platform to realize data storage and permission management.

The blockchain platform can be used as a data storage platform to store data fingerprints, reading and writing records, etc. Smart contracts can realize identity verification and avoid redundant information leakage through encryption technology. Multi-signature enables key retrieval. At the same time, the blockchain is also a registration platform for digital assets.

On this basis, a variety of application scenarios can be realized, such as: APP login, electronic contract signing, supply chain, copyright protection, and asset digitization.

When digital identity and blockchain are combined, coupled with a data management platform, the needs of the alliance chain can be realized, such as the KYC alliance between banks. The essence of the alliance chain is identity-based data mutual trust. It does not matter whether it is a separate chain.

Once blockchain assets are associated with sovereign identities, they can meet government regulatory needs, and regulatory strategies that meet regulatory needs can be added at the application layer.

Therefore, if blockchain is to be applied on a large scale in the future, it is necessary to solve the problem of digital identity. Digital identity is the bridge between the on-chain and off-chain, and the bridge between blockchain and compliance supervision.

As more and more applications and assets are built on the blockchain, big data analysis becomes possible because of the unified identity. Therefore, the combination of big data and blockchain, It’s also inseparable from digital identity.

『Lu』 Yibaoquan’s intellectual property protection platform - micro-copyright, how to do a good job in blockchain certification

Each institution has different ways of safeguarding rights. Likewise, many of them are within the scope of intellectual property protection

『撒』 Can blockchain certificates make the entire electronic data link credible?

More and more companies are joining in digitalization In the transformation team, how to effectively ensure data security will become the core competitiveness of this era. In 2012, the newly revised "Civil Procedure Law" and "Criminal Procedure Law" officiallyElectronic data was included in the statutory evidence classification, laws and regulations related to electronic data began to be promulgated, and electronic data began to move towards the historical stage.
However, in view of the characteristics of electronic data that can be copied, easily tampered with, difficult to consolidate and prove, electronic evidence urgently needs a professional, reliable and judicially credible technology to effectively solve the trust problem of electronic evidence.
Blockchain has significant advantages such as decentralization, distributed accounting, and encrypted traceability, which can well ensure the integrity and authenticity of on-chain data. Once it has been tampered with or forged, it can be discovered. At the same time, because the blockchain has the characteristics of distributed accounting, even if the data on individual nodes is deleted, other nodes can still completely save the data, ensuring the integrity of the entire blockchain certification system. normal operation.
In 2018, the Supreme People's Court clearly stated in the "Regulations on Several Issues Concerning the Trial of Cases in Internet Courts" that the electronic data submitted by the parties shall be verified through electronic signatures, trusted timestamps, hash value verification, blockchain, etc. If the technical means of evidence collection, fixation and tamper-proofing or certification through the electronic evidence collection and storage platform can prove its authenticity, the Internet Court shall confirm it. This is the first time that the legal effectiveness of blockchain technology in electronic data has been affirmed from the judicial level.

Based on the above advantages, blockchain is naturally suitable for electronic data storage. The introduction of blockchain certificate storage can effectively solve the authenticity and legality issues of electronic evidence, making the electronic data certificate storage process more trustworthy. Yibaoquan uses blockchain technology to effectively solve the whole-link trust issue of electronic data from generation, storage, notarization, and proof: when uploading to the chain, the blockchain is used to ensure the originality and integrity of the storage data. After being put on the chain, each judicial node on the preservation chain is used to ensure the credibility and security of the data; during litigation, the evidence is directly passed to the Internet court to improve the efficiency of rights protection.
