㈠ How to understand the distributed technology of blockchain

Blockchain is a distributed ledger technology that securely stores information across multiple systems and creates A trusted source of “truth” that enables the intermediary of so-called “trusted intermediaries” to enable peer-to-peer transactions. Verification with secure distributed storage brings a paradigm shift in establishing trust, with far-reaching consequences.
In the future, Jinwowo Network Technology will continue to explore the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient and safe , an honest Internet community with a shared future.

㈡ How to understand blockchain and blockchain technology

Blockchain technology uses mathematical methods to realize distributed accounting and solve trust issues, thus completing decentralization. It will have a profound impact in many fields such as communications, finance, Internet of Things, government management, etc.
Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. It is a technical method for all people to participate in accounting. The previous accounting methods were centralized and required a centralized intermediary, whether the intermediary was a traditional government, financial institution, notary agency or an emerging e-commerce platform or online payment platform.
In economics, information is sufficient. In fact, very large intermediaries exist precisely because of insufficient information. The existence of intermediaries increases transaction costs and raises transaction thresholds. Blockchain technology is essentially a large-scale collaboration tool. It uses pure technology to make direct value transfer possible for the first time, and continues the trend of decentralization and disintermediation of the Internet. Disintermediary blockchain technology will greatly subvert the information intermediary industry.
Blockchain technology is the basic technology for constructing the Bitcoin data structure and encrypted transmission of transaction information. This technology realizes the issuance and transaction of Bitcoin. The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases, making transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly conduct payment transactions without the participation of a third party.
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks that have reached transactions in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain.
A block contains the following three parts: transaction information, hash hash formed by the previous block and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All nodes compete to calculate the answer to the random number, and the node that gets the answer fastest generates a new zone.block and broadcast to all nodes for updates, thus completing a transaction.

What kind of accounting system is blockchain?

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

㈣ Blockchain Principles

Blockchain is a technology, but it is not a single technology, but the result of the integration of multiple technologies, including cryptography, Mathematics, economics, network science, etc. You can think of it as a distributed shared accounting technology, or as a database, but this database is jointly maintained by all nodes on the chain, and each node has a ledger, because all nodes The ledgers are consistent, different nodes can trust each other, and there is no doubt about the data, so everyone says that the blockchain has technically achieved trust. For detailed professional technology, you can consult some professional technology companies. For example: Jinbo Technology, which focuses on developing blockchain-related products, has a professional R&D team and complete after-sales service. You can call for consultation.

㈤ What blockchain technology application development platforms are currently available in China

The so-called blockchain technology, referred to as BT (Blockchain technology), is also called distributed ledger technology. An Internet database technology characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

㈥What exactly is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Simply put, blockchain is a decentralized distributed ledger database.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. After reading this, you may still be confused. In fact, in vernacular terms, blockchain is a decentralized distributed ledger database. thisThe advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if your copy is lost, it will not be affected.

So what is distribution and decentralization? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer to complete the legal process. What if we use blockchain technology? As long as two people agree to get married and post a message in their circle of friends, the marriage process is completed and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses. They may be scattered around the world, but their mobile phones will help you record the information and tell others who want to know the situation.

If you want to conceal your marriage information, you used to have to modify the records on the Civil Affairs Bureau's computer, but now you have to modify the records on the mobile phones of all insiders at the same time. The more people who know about it, the less likely it is to modify it. Therefore it is an impossible task. This is distribution and decentralization.

On the network, every once in a while, a block will be generated. This block is equivalent to a network record book, which is used to record relevant information that has occurred over a period of time. Waiting for this record book When the record is full, a new record book will be generated. Once the information is recorded, all participants will be notified and everyone's record book will be updated simultaneously.

These record books are eventually connected in series with each other. This is blockchain technology. Because of the use of cryptography technology, if someone wants to unilaterally tamper with the message, it will be verified through the blockchain algorithm protection mechanism. If the time point does not match and the related information does not match, other people will not update their record books. Then this information is invalid.

Therefore, compared with traditional information storage technology, blockchain technology is more secure, transparent, and information is irreversible.

Blockchain is not equal to Bitcoin, it is just an underlying technology invented to realize the digital currency of Bitcoin. Blockchain can be applied in a wider range. In addition to digital currency, it can also be applied in financial aspects such as P2P lending, global payment, micro-finance, electronic payment, remittance, etc. It can also be used in people's livelihood aspects such as intellectual property, elections, and notarization. The prospects for future development are huge.

㈦ What is blockchain and blockchain technology applications

What is blockchain? Blockchain is essentially a decentralized distributed ledger database. It is the underlying technology of Bitcoin and is closely related to Bitcoin. The blockchain itself is actually a series of data blocks generated using cryptographic correlation. Each data block contains information that is effectively confirmed for multiple Bitcoin network transactions.

Whenever an encrypted transaction is generated, miners with powerful computing power in the network begin to use algorithms to decrypt and verify the transaction, creating new blocks to record the latest transaction. New blocks are linearly added to the original ones in chronological orderAt the end of the blockchain, this ledger will continue to grow and extend.

Through the complex setting of public keys and private keys, the blockchain network broadcasts the ledger of all transactions in the entire financial network in real time, distributes transaction records to each client in real time, and also Ensure that each person can only make modifications to his or her own property. Of course, there are also other people's transaction records in the ledger. Although you can see the numerical value and the corresponding transaction address (basically this is composed of a lengthy period of scrambled letters and numbers), you have no way of knowing it without borrowing other technical means. The true identity of the trader.

What is blockchain? Since last year, the concept of blockchain has begun to become popular, especially in some developed countries, and it has received star-level popularity. Blockchain has also been dubbed as a subversion and has the potential to become popular all over the world. Blockchain will first impact the financial industry, and then affect the wider economic field. The prediction is based on several core features of the blockchain: decentralization, distributed ledger, point-to-point transmission, non-tampering, etc. Since the birth of blockchain is quite miraculous, and its development has also attracted attention with the rise of Bitcoin around the world, many people confuse the relationship between blockchain and Bitcoin. Some people think that blockchain and Bitcoin have a father-son relationship, and some people think that blockchain was born after Bitcoin, but in fact, blockchain is actually the underlying supporting technology of Bitcoin, which can be compared to TCP/IP in the Internet. protocol. From a certain perspective, Bitcoin can be seen as the first practical application of blockchain that emerged at the same time as blockchain.

Application of blockchain technology? Bubi Blockchain has been focusing on the R&D and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has made substantial innovations in many aspects, forming a number of core technical achievements, such as: Mathematically proven distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.

What is blockchain? Blockchain technology applications? We can use Bitcoin to describe several application prospects of blockchain. Bitcoin can be said to be a decentralized currency or asset. Every Bitcoin can be traced and viewed by anyone at any time. This application prospect means that if transactions between people can return to the original form of barter exchange from the current currency as a means of measuring value, then the measurementThe measure of value is no longer legal currency, but measured by Bitcoin or other virtual currencies or virtual assets generated by the blockchain. The benefits brought to us by the current sharing economy are just the tip of the iceberg. If the characteristics of Bitcoin that can be traced, queried and cannot be tampered with are applied to credit record systems, identity authentication systems or property rights authentication systems, then many things such as proving “Is this house my property?” “I am unmarried” "Still married" series of difficult questions will no longer exist at all. According to the current development trend, blockchain will not only reshape all aspects of money markets, payment systems, financial services and economic forms, but also change every field of human life.
