㈠ What 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. Blockchain 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 its Validity of information (anti-counterfeiting) and generation of the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

blocks Application of blockchain:

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

For example, Visa launched Visa B2B Connect based on blockchain technology, which can provide institutions with a lower-cost, faster and safer cross-border payment method to process business-to-business transactions worldwide. .

Be aware that traditional cross-border payments require 3-5 days of waiting and a 1-3% transaction fee. Visa also launched the first Bitcoin debit card in conjunction with Coinbase, and Citibank is testing the cryptocurrency Citicoin on the blockchain.

What does cdc warehouse mean?

CDC: central distribution center.

Distribution centers can be divided into two categories: Central Distribution Center (CDC) and Regional Distribution Center (RDC) according to their size and location in the circulation channel.

CDC service refers to accepting multiple varieties and large quantities of goods provided by suppliers, and after carrying out storage, custody, sorting, distribution, circulation processing, information processing and other operations, according to the orderer's requirements Deliver the completed goods to the organization and logistics company designated by the customer.

The CDC services of Sinotrans Guangdong Co., Ltd. include storage, custody, sorting, distribution, value-added services and information processing, etc., and extend to the front end of the supply chain to the factory production line and offline receiving, factory Ground pickup, factory to CDC transfer transportation and other services.

Extend CDC backward toRDC's transportation services, export cargo declaration, booking, etc., thus forming a comprehensive logistics service. The Guangdong company uses an advanced WMS system in CDC services, which can record every action of all products into the information system and accurately grasp each step. The condition of a product.

The application of WMS system not only improves work efficiency, but also greatly improves accuracy. In addition to data management, the WMS system also has functions such as settlement, query statistics, and online customer inquiries. Customers can log in to the website to query the quantity and status of various products, and can track and manage products in real time.

Regional Distribution Center - Regional Distribution Center RDC is a type of distribution center that delivers to users in a specific area with strong radiation capabilities and inventory preparation. Sinotrans Group is based on the actual needs of customers.

㈢What exactly is blockchain

What is blockchain?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system [1].
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.
The current situation of digital currencies is that a hundred flowers are blooming. Here are some common ones: bitcoin, litecoin, dogecoin, dashcoin. In addition to currency applications, there are also various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT , SIA, BitShares, MaidSafe, Ripple and other industry applications.
On January 20, 2016, the People’s Bank of China Digital Currency Seminar announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013. [4]
On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established. Huobi is a joint developerOne of the starting units. [5]
Some areas where blockchain can be used are:
▪ Smart contracts
▪ Securities trading
▪ E-commerce
▪ Internet of Things
▪ Social communication
▪ File storage
▪ Proof of existence
▪ Identity verification
▪ Equity crowdfunding
We can compare the development of blockchain to the development of the Internet itself , something called finance-internet will be formed on the Internet in the future, and this thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chains and industry chains (local area network), and the bitcoin series starts from public chains (Wide Area Network), they all express the same concept - digital assets (Digital Asset), and finally converge to an intermediate balance point.
The evolution of blockchain is:
▪ Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0 ——The implementation of distributed applications in various industries
Blockchain is divided into three categories, which is introduced in detail in the book "Blockchain: Defining the New Pattern of Future Finance and Economics" [2] issued by Currency,< br />Hybrid blockchains and private blockchains can be considered as broad private chains:
Public Blockchains (PublicBlockChains)
Public blockchains refer to: any individual or group in the world Transactions can be sent and effectively confirmed by the blockchain, and anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .
Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes to participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, just become distributed accounting, how many pre-selected nodes, how to determine the number of each block The bookkeeper becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a publicA company, or an individual, has exclusive write permission to the blockchain. This chain is not much different from other distributed storage solutions. (Dec2015) Conservative giants (traditional finance) all want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.
