Water chain blockchain

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated 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, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain 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

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

2. 650mah is battery capacity
bak means that the cell is proced by bicker company<
423048 refers to the specification of the cell (internal part of the battery), which is 4.2mm in thickness * 30MM in width * 48mm in length (please check it yourself)
btc8g26 / 04kh is the traceability code of the battery. If you find that there is a problem with the battery, especially the safety problem, return it to the manufacturer, and the manufacturer can find out the proction material, proction process, proction shift date and other information of the battery according to this code, so as to find out the cause of the battery problem, and improve the proction material and process, so as to avoid similar problems with other batteries. If necessary, call back the problem batteries of the same batch, Avoid greater losses, especially when there are fatal problems such as fire
I am a proction engineer of lithium battery. If you have any questions, please leave a message on my blog
ha ha, is the answer professional enough?

3. Water chain, like other digital currencies, has no value in essence, because it is not legal money. But with more people, it has value. So does water chain. Circulation is bound to have value. As long as people with consumer demand want to get water chain, the value of water chain will increase. Water chain has a variety of application scenarios, so that the value of water chain continues to improve
as a new type of digital currency of blockchain, water chain absorbs the advantages of other digital currencies and improves and solves the shortcomings of digital currency. As a proct of blockchain 2.0, water chain has perfect application scenarios and transaction mode, and will be the leader in the field of digital currency level blockchain in the future.
