❶ What does blockchain mean?

Blockchain is a new application model of computer technology 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 decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of The information of Bitcoin network transactions 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 public management, energy, hotel management, transportation and other fields, but the centralized nature of these fields also brings some problems , can be transformed using 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 the operating systems and firmware of some important infrastructures. If it has not been tampered with, the status and initialization of the software can be monitored to detect bad tampering and ensure that the data transmitted by the system using IoT technology has not been tampered with.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the renaissance that generations have been striving for. dream.

Puyin Group held a Puyin Blockchain Finance Guiyang Strategy Release Ceremony in Guizhou on December 9, 2016. At the meeting, the blockchain will realize the digital circulation of assets and the blockchain financial transaction model. , and discuss the application of blockchain services and social public industries.

❹ What is blockchain?

Blockchain is a distributed data storage, New application models of computer technologies such as point-to-point transmission, consensus mechanisms, and encryption algorithms. Simply put, blockchain is a decentralized distributed ledger database.

The meaning of data storage:

Data storage is a temporary file generated during the processing of data flow Or the information you need to find during processing. Commonly used storage media are disks and tapes. How storage is organized varies depending on the storage medium. Data on tape is onlySequential file access; on the disk, sequential access or direct access can be used according to usage requirements.

The data storage method is closely related to the organization of data files. The key is to establish the correspondence between the logical and physical order of records and determine the storage address to improve the data access speed. Among the various connection methods between servers and storage, DAS was once considered an inefficient structure and inconvenient for data protection.

Direct-attached storage cannot be shared, so it often happens that a certain server has insufficient storage space, while other servers have a large amount of idle storage space that cannot be used.

❺ What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet data. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. Lightweight Bitcoin wallets use online confirmations, which means they do not download blockchain data to device storage.
Bitcoin’s many altcoins also use the same design, with slightly different proof-of-work and algorithms. Such as: Proof of Stake, SCrypt, etc.

❻ What does blockchain mean?

Blockchain is a distributed database system [1] participated by nodes. Its characteristics are that it cannot be changed or forged. It can also be understood as an accounting system (ledger). It is an important concept of Bitcoin. A copy of the complete Bitcoin blockchain records every transaction of its token. Through this information, we can find every address owned at any point in history. value.
The blockchain is composed of a series of data blocks generated using cryptographic methods. Each block contains the hash value of the previous block, starting from the genesis block. Connected to the current block to form a block chain. Each block is guaranteed to be generated after the previous block in chronological order, otherwise the hash value of the previous block is unknown. These characteristics make double-spending of Bitcoin very difficult. Blockchain is the core innovation of Bitcoin.
The emergence of the blockchain concept was first mentioned in Satoshi Nakamoto’s Bitcoin white paper [2], but it exists in the form of a proof-of-work chain. The following is Satoshi Nakamoto’s description of the blockchain concept: The timestamp serverck), implement a random hash and timestamp, and broadcast the random hash, just like a post on the News or Usenet. Obviously, this timestamp can prove that specific data must indeed exist at a specific time, because only if it exists at that time can the corresponding random hash value be obtained.

❼ What does blockchain mean?

Blockchain is a shared database. The data or information stored in the database cannot be forged, can leave traces throughout the process, and can Tracing the source and other features.

Blockchain information is very popular on the Internet. Many people think that blockchain is a high technology or a financial product. What does blockchain mean? Let us find out together below.

Blockchain originated from Bitcoin. On November 1, 2008, a person calling himself Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Electronic Cash System" "The article explains the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marks the birth of Bitcoin.

On January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

Blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Blockchain is a new application 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. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

As an important breakthrough for independent innovation of core technologies, the security risk of blockchain is regarded as a major shortcoming that currently restricts the healthy development of the industry. Frequent security incidents have sounded the alarm for the industry. To embrace blockchain, we need to accelerate the exploration and establishment of a security system that adapts to the blockchain technology mechanism.
