1.
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
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 by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
some areas where blockchain can be used can be as follows:
& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication
&9642; Equity crowdfunding
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
The evolution mode ofblockchain is as follows:
& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries
2. Blockchain is a kind of distributed ledger technology. By safely storing information across multiple systems, and by creating reliable "truth" sources, it realizes the intermediary of so-called "trust intermediary", so as to realize point-to-point transactions. Relying on secure distributed storage for verification brings a paradigm shift of trust building, which has a profound impact
in the future, jinwowo network technology will continue to tap 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, safe and honest Internet community of destiny.

3. Blockchain originated from Nakamoto's bitcoin. As the underlying technology of bitcoin, it is essentially a decentralized database. It refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past
blockchain technology is a technology solution that does not rely on a third party and stores, verifies, transmits and communicates network data through its own distributed nodes. Therefore, from the perspective of financial accounting, some people regard the blockchain technology as a distributed, open and decentralized large-scale network bookkeeping book. Anyone can use the same technical standards to add their own information at any time, extend the blockchain, and continuously meet the data entry needs brought by various needs
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
blockchain technology is considered to be the most disruptive technological innovation since the invention of the Internet. Relying on the ingenious distributed algorithm of cryptography and mathematics, it can make the participants reach a consensus without the intervention of any third party center on the Internet where the trust relationship cannot be established, and solve the problem of reliable transmission of trust and value at a very low cost
bitcoin peer-to-peer network stores all transaction history in "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. After bitcoin transaction data is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
digital currency is easy to be regarded as a new currency by traditional financial institutions, but in fact, the significance and value of its underlying technology is far greater than its monetary attribute. Taking bitcoin as an example, it is generally regarded as a kind of point-to-point digital currency, but from the technical level, it is actually a point-to-point decentralized network platform, which relies on the blockchain technology. Digital currency is a global peer-to-peer network platform based on blockchain technology. Represented by bitcoin, the application of blockchain in the field of digital currency is also known as blockchain 1.0 [1].

4. Distributed applications are software applications that are mainly stored on cloud computing platform and run on multiple systems at the same time. These systems run on the same network and communicate with each other to complete specific tasks or commands. With distributed application program; Traditional applications need a system to complete the assigned tasks
by storing information blocks among nodes in the blockchain network, the failure of a system will not make the blockchain bankrupt. When the computer or system fails, other systems will act as backup and keep running, independent of the system that is down. Once all active nodes receive and confirm that the transaction is valid, the block (transaction) will be added to the chain (general ledger) for public access. Even if one or two nodes exit the network, all nodes can still maintain the ability of normal operation, which can ensure that users continuously record and confirm their transactions in an uninterrupted and timely manner<
