❶ What is used to store data in the blockchain to make the super server trustworthy third party

Hello, what is used to store data in the blockchain to make the super server trustworthy? Third party? The main role of blockchain is to act as a trusted third party, such as building transaction centers and data centers based on blockchain. The existing centralized method of establishing a set of public databases or establishing connections between multiple enterprise databases presents shortcomings such as high cost, low efficiency, and low security. It is usually necessary to find a credible social organization, an authoritative government department, or a recognized third-party industry leader to establish a centralized database and complete data storage, exchange and sharing through interactive services. In this scenario, each enterprise also has its own associated database system. The consistency and synchronization between different databases need to be repeatedly confirmed and verified with a third party that owns the shared database, or even manually verified, resulting in the generation of shared data. The reuse process is complex and inefficient. In addition, since all data is placed in a so-called authoritative third party, there is a natural risk of external attacks and internal employees stealing data. Once this authoritative central server is paralyzed, all external businesses connected to it will be interrupted. This is actually a potential challenge currently faced by Internet service providers, especially giants, and it is also a time bomb. The core capability of blockchain is to provide a consistent set of accounts, using blockchain technology to replace the role of this third-party Internet service giant, allowing multiple companies to use the same accounting system and record the same ledger. In view of the blockchain database The consistency and history cannot be tampered with, which can simplify and transform business processes, protect data integrity, and improve business operation quality and management efficiency. And when a certain node is paralyzed, the entire business will not be interrupted. Please refer to it!

❷ The last shot of the blockchain battle is fired at the end of the year, Vpay may become a hot spot in the currency circle and a top public chain incubator

The application of blockchain technology, from abroad to domestic, never Recognition can lead to gradual application, and digital currency has also been accepted and adopted by various countries, and its development cannot be underestimated.

The application of digital assets in many blockchain projects requires a platform for circulation and communication. From scratch, the project needs strong support from technology research and development to widespread application rather than stillborn. There is a blockchain incubator. vpay has nearly 3 million users, with an increase of 20,000 people every day. Strong data support enables Many digital public chains and angel round crowdfunding came for this purpose.



vpay, mid-October, good things happen one after another.

On October 11, International E-Network officially connected 50 companies around the worldExchange digital sharing enables synchronization of data from major exchanges around the world.

On October 13th, ABS chain crowdfunding opened a new encryption world.

On October 19, VTS Internet of Things public chain started crowdfunding.

On October 18, the ASX opened for registration; on October 22, VRT and the ASX (AOEX) over-the-counter trading area made a strong debut.

In October, there were also Vpay Cambodia study tours, V charity events, etc. A package of activities allowed the Vpay family to enjoy a feast of wealth, and also made many people in the currency circle lock Vpay and add vitality.

The great good news from the Cambodian business school, you don't know very much, let alone understand.

If you are still doubting the security, the feasibility, and the prospects of Vpay, then you may once again lose the opportunity to make big money. Keep up with the rhythm of the platform. Today next year will be the harvest season for everyone. You will make money you have never made before, not hundreds of thousands, but maybe millions, or even tens of millions.

1. Vpay cooperates with the National Bank of Vanuatu, a South Pacific island country, to issue Vpay bank cards, and the balance can be withdrawn directly through the bank card.

2. The Lao national government is preparing to use government actions to promote Vpay nationwide and regard Vpay as the "Alipay" of Laos.

3. At the end of October, E-Net and Australia-Net will open VRT transactions. Friends in the currency circle can enter Vpay from the capital market, exchange USDT for VRT, and then use VRT to increase the balance by five times, and then use it in reverse The balance is exchanged for Vpay coins to participate in crowdfunding. Old members can also use VRT to withdraw cash to their bank cards through the above two exchanges. E-Net Exchange is connected to the top 17 exchanges in the world, which means that as long as you log in to E-Net, you are logging into the 17 largest exchanges in the world.

  4. At the end of October, 100,000 communities began to be formed. The tool is "WeChat", the participants are all members, and the qualifications are members who can obtain the right to operate super nodes. Super nodes can enjoy dividend rights for 14 years. Members at the big-name level have already begun to make plans. Members who are not big-name but understand their belief in Vpay are preparing to invest more funds in dozens of VIPs, and then win the right to operate super nodes.

5. The platform has been upgraded from version 1.0 to version 2.0. From allowing members to join Vpay to manage their finances five times to allowing members to hold various Vpay crowdfunding chains, they will become multi-millionaires. If you can still speculate in coins in the currency circle, your wealth can reach another level.

6. The balance is currently consumed offline in 58 countries, and the balance can be converted into the legal currency of each country at any time.

7. The "SMTH", "IPC", "ABS" and "VTS" public chains crowdfunded on the Vpay platform have become the country's national strategic layout for building smart cities and smart societies. The prices of these public chains are expected to rise sharply soon. (All kinds of official media can find news reports such as the actual applications of these public chains.)



Finally, I solemnly remind them again.

Friends who are willing to believe in Vpay and are willing to work hard on the Vpay platform to earn millions of wealth back, please understand the above content carefully.

Everyone has two paths to choose from. Which path you choose is up to you. Of course, you can also choose not to choose any path and just follow the old path step by step.

No matter you choose to share and promote members, or choose to invest additionally, the purpose of limiting this time is to enable you to participate in crowdfunding. Only by participating in crowdfunding can you buy the public chain of crowdfunding. Your wealth can grow exponentially.

There are no leeks in the currency circle, only players. Vpay is a place where merchants, consumers, investors, and entrepreneurs compete on the same stage to achieve financial freedom.

Seize the opportunity and wealth will belong to you.

❸ Blockchain has been elevated to a strategic level, and cloud computing + 5G will benefit in the long term (shareholding)

Blockchain has risen to a national level, "blockchain should be used as an important breakthrough for independent innovation of core technologies, and the development of blockchain technology and industrial innovation should be accelerated." This is undoubtedly a big news for the blockchain concept sector. Blockchain, digital currency and other concept stocks are in the spotlight.

Blockchain is an organic combination of existing mature technologies. Its core technologies mainly include distributed ledgers, consensus mechanisms, smart contracts and cryptography, thereby achieving a chained data structure that is difficult to tamper with.

The physical basis for building a blockchain is a distributed ledger, which is an independent and complete data storage in multiple network nodes. In order to solve the problem of consistency certification of distributed systems, consensus algorithms are introduced at the system level. The most widely used ones include PoW and PoS (mainly used in public chain systems such as Bitcoin, supporting the issuance of tokens, which consumes a lot of computing power), and PBFT ( Mainly used for alliance chains or private chains, no tokens required).

A Tianfeng Securities research report points out that the characteristics of blockchain technology will directly drive the communication industry chain in three aspects:

1) Computing power carries servers and data Central demand;

2) Distributed storage drives the demand for public cloud/private cloud, and blockchain applications will also accelerate the progress of enterprises on the cloud, creating long-term demand for cloud computing, IDC, switches/servers;

3) The 5G network with low latency and high speed is an important way to solve the low transaction speed of blockchain.

Tianfeng Securities pointed out that the application and deployment of blockchain will drive demand in many aspects of the communications industry. Specifically:

1) Under the public chain model , the consensus algorithm requires a large amount of computing power support. Currently, the equipment used in consensus calculation is mainly servers (mining machines), which will generate a large number of server demands and drive the growth of IDC demand.

2) In both public chain and alliance chain modes, blockchain requires a large number of distributed nodes to store ledger information, which will bring about public cloud/private cloud storage requirements. Further boost long-term demand for cloud computing, IDC, and switches/servers.

3) Due to the characteristics of the distributed architecture of the blockchain, factors such as different node computing capabilities, network conditions, etc., the transaction speed of the blockchain is low (7 transactions per second on the Bitcoin network, 15 transactions on the Ethereum network) / second, which is significantly lower than VISA’s peak of 56,000 transactions/second and Alipay’s 256,000 transactions/second). In order to solve the problem of large-scale application of blockchainWith transaction congestion and rising costs, high-performance networks have become an important link. The high speed, low latency characteristics and natural large-scale edge node resources of the 5G network perfectly meet the needs of blockchain technology.

Blockchain technology has been elevated to the level of an important breakthrough for independent innovation, and industrial investment, research and development, and implementation progress are expected to continue to accelerate. Tianfeng Securities believes that as the core carrier of blockchain deployment and operation, the communications industry chain is expected to benefit in the long term. Specifically:

❹ Baidu’s release of “Super Chain” is an upgrade of “blockchain” Edition

The dividends of the mobile Internet era are over, and the next stop is blockchain. On June 4, Xiao Wei, a network blockchain scientist, presented the network's new generation blockchain network operating system "Super Chain" for the first time at the opening ceremony of the 2018 Chain Valley Lecture Hall.

A big event is coming to the blockchain field, and that is the release of a super chain on the Internet. In the past few years, many companies have entered the field of blockchain. This time the network released a super chain, and it is a solution to promote the development of blockchain, which indeed has great positive significance. This solution is also considered as the network embracing blockchain. Moreover, future scenarios are unanimously optimistic.

The Internet once missed the opportunity of the mobile Internet. The most obvious example is the disastrous failure in the O2O field. The Internet Nuomi, which once made heavy bets, is now facing the challenges of Ele.me and Meituan. Comment on the decline of the encirclement. The network, which has no hope of breaking through, has turned its focus to artificial intelligence, hoping to make a comeback in the era of artificial intelligence.

As everyone knows, in addition to artificial intelligence, there is also a revolutionary technology that is setting off a craze around the world, and it is blockchain. The Internet never wants to miss the opportunity to change its destiny again.

❺ What happened to the blockchain recently?

There is a word recently.

It often appears on the Internet,

It’s amazing to see this word,

but I often don’t know what it means.

The word is called

"Blockchain"

Recently, "Blockchain" has been named publicly again.

What is "blockchain"?

From an academic perspective, blockchain is a new usage model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms.

Blockchain is essentially a decentralized database.

Explain this.

Many people still don’t understand.

Hypothetical environment:

Methods to solve the blockchain problem:

If you use the whole family to keep accounts, the above problems will not exist, because you keep the accounts, your father keeps the accounts, and your mother keeps the accounts. They can all see the ledger, you can’t change it, and neither can your parents. So you can't help the dad who wants to buy cigarettes, nor can you help the greedy dad.

In other words, the blockchain

this distributed digital ledger

records everything that has happened

and the transactions are unanimously approved by the system.

Each block is a ledger.

It can not only record transaction information

but also has more functions.

Multi-functional "Blockchain"

Each block is like a hard disk, and all the information on it is saved and then encrypted using cryptography. This saved information cannot be tampered with.

Looks like it

Blockchain has some super technical properties.

Characteristics of blockchain

1. Exceptionally safe: Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and the data is completely replicated (distributed) across multiple computers superior. Unlike centralized databases, there is no single entry point for attackers, so data is more secure.

2. Non-tamperability: Once entered into the blockchain, no information can be changed, and even administrators cannot modify this information. Once something happens, it cannot be changed. This property is of great significance to the ever-changing and ever-changing online world in which humans live.

3. Accessibility: All nodes in the network can easily access information.

4. No third party: Because of the decentralization of the blockchain, it can facilitate peer-to-peer transactions. Therefore, whether it is a transaction or fund exchange, no third party approval is required. Blockchain itself is a platform.

What will the future development and usage scenarios of blockchain look like?

1. Digital Identity

Many people will encounter the dilemma of "proving that my mother is my mother" when applying for various certificates. With blockchain, there is no need to worry anymore.

Our original birth certificates, real estate certificates, marriage certificates, etc. It needs a central node for everyone to recognize. Once cross-border, contracts and certificates may become invalid due to the lack of a global central node.

The immutable nature of blockchain technology fundamentally changes this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the whole world. Of course, it is also easy to prove "my mother is my mother".

2. Health care

To put it simply, it is to use the blockchain to establish a universal record library with timestamps, so as to achieve the purpose of extracting data information from different databases. For example, when you go to see a doctor, you can have repeated examinations without changing hospitals, and you don’t have to go back and forth for medical insurance reimbursement, which can save time and money.

3. Travel consumption

For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform earns commissions from them. The use of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to achieve direct connection and transactions.

4. More convenient transactions

Blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when specific conditions are met, meaning that automatic payments can be released when both parties agree that their conditions are met.

5. Strictly control product quality.

If you buy an apple, with blockchain technology, you can know the entire process from production to distribution. There are government regulatory information, professional testing data, corporate quality inspection data, etc. Smart supply chain willMake our daily food and commodities safer and give us more peace of mind.

6. Property rights protection

Related questions and answers: What does blockchain mean?

Blockchain is a new usage model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database, and 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 transactions. The information is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

Blockchain is closely related to people's production and life in the fields of public management, energy, hotel management, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

The decentralized fully distributed DNS service can realize domain name query and resolution through point-to-point data transmission services between each other in the network, and can be used for certain important infrastructure operating systems and firmware without being tampered with. It is possible to monitor the status and initialization of software, detect bad tampering, and ensure that data transmitted by systems using IoT technology has not been tampered with.
