How to trace the origin of blockchain

1.

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

2. With the help of blockchain technology and alliance chain node, wangchain technology integrates and writes the information of commodity raw material circulation process, proction process, commodity circulation process and marketing process into the blockchain, and uses the tamper proof attribute of the blockchain to realize the whole process traceability of one thing one code

3. Traceability chain TAC has overcome the problem of cross chain digital asset transfer between traceability chain public chain and Ethereum public chain. After the main network goes online, cross chain digital asset transfer function will be launched one after another
in the future, the commodity traceability service instry will continue to develop in the direction of globalization and digitization, and more enterprises will certainly join this field and build corresponding traceability system based on their own needs
traceability chain applies blockchain technology to build public chain and realize cross chain interaction, which can be said to be forward-looking in strategic layout.

4. I was engaged in this instry in Shanghai before, and changed to another instry e to personal reasons. The blockchain technology itself has no traceability ability. It must use some other methods to obtain information and upload the information to the blockchain ledger to achieve the purpose of traceability. For specific operation methods, please refer to the official website of akte for more information. Thank you~~~

5. The origin of blockchain comes from "bitcoin: a peer-to-peer e-cash system" published by Nakamoto in 2008. According to this concept, the first proct "bitcoin" was born. The origin of blockchain technology is usually attributed only to the actions of some mysterious geniuses who work under the pseudonym of Nakamoto. This view of history often makes the technology seem almost magical and difficult to understand. When people understand the actual history behind the development of these systems, it is more fundamental. In this section, I will outline the most important topics in decades of research on consensus algorithms and distributed systems that led to the creation of blockchains.

For blockchain messages, bitcoin is to blockchain what e-mail is to the Internet. As we all know, e-mail for the first time in the history of human information dissemination and exchange realizes the function of timely, free and verifiable sending data to anyone else in the world. Both the sender and the receiver can save copies of the data sent in e-mail. However, the e-mail data copies retained by both parties also become an inherent defect of online value transfer, because both parties have their own value. Therefore, it is necessary to ensure that the value is not double paid by the existence of third-party institutions, such as banks, stock exchanges, clearing centers or notaries. As an internet protocol, bitcoin can transfer value to each other instantly and safely without the existence of intermediary organizations such as credit granting third party, which reces transaction cost and improves transaction efficiency. Xiaobian now arranges the schematic diagram of blockchain technology and related technical principles for you

literally, blockchain is a distributed account book system composed of a series of data blocks generated by cryptographic methods. Each data block contains a large amount of transaction information, which is used to verify the validity of its information and generate the next block. These blocks are arranged in the order of generation, and each block is a node

the remarkable feature of blockchain is that there is no third-party supervision as a central server, and the transaction information in the block cannot be changed. The information contained in the block can be financial transactions or any other digital transactions, including documents. The success of the Internet business model, which has dominated the business world of human society for a long time, depends on the third-party financial institutions as credit granting institutions to process and mediate electronic transactions. The role of the third-party credit granting institutions is to verify, protect and save transaction records

However, there are still a large number of fraulent online transactions, which need to be mediated by a third party, resulting in higher transaction costs. Bitcoin, based on blockchain technology, uses encryption to prove, rather than credit a third party, so that all parties willing to trade can achieve online transactions through the Internet

every transaction can be protected by digital signature and sent to the "public key" of the receiver who uses the sender's "private key" for digital signature. The owner of bitcoin, namely cryptocurrency, needs to prove the ownership of its "private key" in order to consume and trade online. The receiving party uses the sender's "public key" to verify the digital signature on the transaction, that is, the ownership of the other party's "private key"

each transaction is broadcast to each node in the bitcoin network and recorded in the public ledger after verification. Moreover, before each transaction is recorded in the public ledger, it needs to verify its validity. Therefore, the verification node needs to ensure two things before recording each transaction: that is,

(1) consumers have the signature authentication of their encrypted electronic currency

(2) there are enough encrypted e-money in consumer accounts

Figure 1 shows the transaction process and principle based on blockchain technology

I hope this answer will help you
