1. Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:
1, open source code
upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public
2, complete decentralization
anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"
3. Developing decentralized applications
through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers
2. The three characteristics of blockchain are well known, that is, decentralization, transparency and non tampering. The tamper proof feature makes blockchain used in many places. Such as proct traceability, privacy protection and so on
because the proction process it traces back to is artificially uploaded, so even if it is tamperable data, the authenticity of the data can not be guaranteed, and the substantive problem still can not be solved
generally speaking, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has promoted the development of the times, and I believe its future is worth looking forward to
3. They will record proction information, logistics information, sales information and other data on the chain. It's equivalent to a person who has an ID card, but the ID card is a code. When you go in, you can see complete information. Family name, even "parents" can know, but also can't change! With this kind of blockchain for anti-counterfeiting traceability, even the labor cost of playing Jia is saved.
4. There are two key characteristics in blockchain Technology: decentralization and tamper proof. This avoids the possibility of counterfeiting technically. For example, the vonetracer traceability system of wangchain technology will upload all links of a commodity to the blockchain. Users can scan the QR code to know all the information of the commodity. Agricultural procts enterprises use this technology to avoid the possibility of counterfeiting.
5. At present, there are many companies that do anti-counterfeiting traceability system on the market, but there are few platforms that really implement blockchain technology. Miaowa anti-counterfeiting traceability platform is the blockchain technology that is used to collect data distributed in different nodes and verify the authenticity of data on the premise of ensuring that the data can not be changed
6. Hello, there is no problem with anti-counterfeiting. What procts do you sell? However, few companies have mastered the blockchain technology, which tends to be more conceptual. The price of real blockchain anti-counterfeiting traceability is also very high, ranging from hundreds of thousands to millions. I hope you can distinguish well. Don't spend a lot of money on ordinary traceability system, If you have common traceability needs, you can find Chinese anti-counterfeiting
7. Blockchain technology has gone from blockchain 1.0 in 2009, the application of
digital currency represented by bitcoin bits to blockchain 2.0 in 2015, the combination of digital currency and smart contract to blockchain 3.0 in 18 years, breaking through the financial field and benefiting other instries. Shangmiao code anti-counterfeiting traceability platform combines the four characteristics of blockchain Technology: 1. Decentralization: the blockchain consists of many nodes to form an end-to-end network, and there is no centralized equipment and management organization. 2. Tamper proof: the database modification of a single node or even multiple nodes cannot affect the database of other nodes. 3. Transaction transparency: the operation rules of the blockchain are open and transparent, all data information is also open, and each transaction is visible to all nodes. 4. Traceability: each transaction in the blockchain is connected in series with two adjacent blocks by password method, so it can be traced back to the origin and development of any transaction. Miao code anti-counterfeiting traceability platform collects the data distributed in different nodes, verifies the authenticity of the data on the premise of ensuring that the data can not be changed, and finally presents it to consumers.
8. The main feature of blockchain anti-counterfeiting is that it can't be changed. As long as the principal has done anti-counterfeiting, no one can cheat any more. Changsha high tech Zone has built a service platform project of SMIC blockchain, which is blockchain + public service, and it is for enterprise users to collect on the chain. At the same time, there will be agencies and appraisal centers to join, It seems that we have cooperated with Dean forensic center now.
