What is the blockchain for?

What is the blockchain for? There are many things in the world that touch our knowledge blind spots, and blockchain is one of them. However, blockchain is often mentioned, so we also need to understand blockchain. Next, I will take you to understand what blockchain is for.

What is blockchain for 1

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Applications

1. Art industry

Ascribe allows artists to use blockchain technology to declare ownership and issue certificates. Numbered, limited edition pieces can be digital for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.

2. Legal industry

BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.

3. Development industry

Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

4. Real estate industry

They plan to modernize the entire industry chain process and solve various problems faced by everyone involved in real estate, including the naming process, land registration, Agency intermediaries, etc.

What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods.

Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information, prevent counterfeiting and generate the next block. It is a set of data storage mathematical architecture constructed in a way that is almost impossible to forge or tamper with, and can be used to store all kinds of valuable data.

The Cyberspace Administration of China issued blockchain information service management regulations on January 10, 2019, which will take effect on February 15, 2019.

What is the blockchain for 3

Before talking about the blockchain, let’s talk about the Internet. The Internet is now an indispensable part of us and is closely related to our lives. First of all, the biggest disadvantage is It can only transmit information. The key is that the information data on the Internet can be set artificially. For example, it is often said to browse Weibo and so on. Secondly, there are bugs in the Internet environment, which means that there cannot be equality in data ownership. This is to say that there are some disadvantages of the Internet.

Putting aside what blockchain is, let’s talk about the Internet and blockchain. Blockchain and the Internet are a parallel relationship, and they can also be a continuation of mutual complementation. So what is a blockchain? A blockchain is actually a series of data blocks that are associated using cryptographic methods. Simply put, there are many data blocks connected in a certain time sequence. It can also be said that a blockchain is a ledger. , but the account book is different from the ordinary computer account book. The blockchain account book is jointly kept by all computers in the world. The biggest feature is that it cannot be tampered with.

What can the blockchain do?

1. Machine trust

In professional terms, it is because of the blockchain The tamper-proof nature of technology fundamentally changes the centralized credit model. Build lowest-cost credit with code. In other words, as long as the code on the blockchain is executed, there is no need to worry about the possibility of stopping midway. Creating a new era of machine trust. Blockchain is expected to lead us from personal trust to the era of machine trust. In other words, his trust cost is close to zero.

2. Value transfer

The Internet can only transfer information but cannot realize the value of information. That is to say, the transition from the information Internet to the value Internet will Some fundamental changes occur. Blockchain transfer will be more convenient, while also achieving low-cost transfer of value.

3. Smart contract

This is also one of the most obvious features of the blockchain. When a pre-programmed condition is triggered, the smart contract begins execution and cannot be stopped by either party, and cannot be deleted or modified.Wait until the contract ends.

4. Token mechanism

Token mechanism is actually a form of value circulation. Through the tokenization of physical or virtual assets, it can work directly through the network. Mainly There are cost reductions, time savings and crossing borders. It can also be understood as proof of rights and interests. Xunlei and "LinkToken" all belong to the "Token" blockchain.

Blockchain characteristics

It has the characteristics of decentralization, anonymity, autonomy, openness, traceability, non-tampering, collective maintenance and no need for recognition. At present, we often talk about the following types of blockchains: public chain, private chain, alliance chain and side chain.

The application value of blockchain

1. Blockchain information security

Information security is one of the biggest features of blockchain, such as Facebook some time ago The leaks brought some negative social impacts. On May 8, Facebook established a blockchain department to study how to use blockchain technology.

2. Underlying technology

This is one of the most imaginative and core technologies of the blockchain. This is a highly professional academic. Let’s give a simple example. , the most famous project of this underlying technology is Ethereum.

3. Bass service

This is a series of services provided by using data generated by the blockchain, such as queries, etc. In terms of network and Tencent, both have launched their own Bass services. .

Where are the five blockchains mainly used?

At present, relatively mature areas include blockchain + medical care, blockchain + Internet of Things, blockchain + culture and entertainment, blockchain + public welfare, etc.

⑦ In addition to being used in virtual currency, what other aspects can blockchain technology be used in?

In addition to being used in virtual currency, blockchain can also be used in the financial field, digital currency, securitiesTransactions, fund management, customer credit reporting and anti-fraud, digital points, etc. The usage rate of blockchain in our country is still relatively high at present. Perhaps what we have heard the most before is that it is used in virtual currency.

In summary, in today’s society, blockchain technology has provided us with a wide range of help, and we must make good use of this Technology, use it in various related industries to make our industry develop faster and ensure the interests of our people.

⑧ What fields can blockchain be applied to?

Financial applications: Blockchain has inherent advantages in the financial field. On the Internet, this is the genetic decision of blockchain. of.
(1) Insurance business: With the development of blockchain technology, in the future, personal health status, accident records and other information may be uploaded to the blockchain, allowing insurance companies to be more timely and accurate when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital bills: The pain points in this field lie in three risk issues. Operational risk, due to the centralization of the system, once the central server has a problem, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral hazards in traditional centralized systems (4) Cross-border payments: The pain point in this field is the long payment cycle , high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, the transactions are open, transparent and cannot be tampered with. There is no third-party payment institution to join, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit management: The pain points in this field are the lack of data sharing, asymmetric information between credit reporting agencies and users; limited formal market-based data collection channels, and the battle for data sources is time-consumingA lot of costs; data privacy protection issues are prominent, and traditional technical architecture is difficult to meet new requirements. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. The blockchain's deintermediation, consensus mechanism, and non-tampering characteristics eliminate the need for third-party credit enhancement agencies to verify the authenticity of various relevant certificates in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain's deintermediation, consensus mechanism, and non-tampering characteristics increase data flow efficiency, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
Applications:
(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things application of blockchain technology will has become a very important application field.
(3) Blockchain + IP Copyright & Culture and Entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain features disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors.
(4) Blockchain + Public Services & Education: In public services and educationIn the fields of education, charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on a credible third party for credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.
