Block chain technology is the currency of the underlying technology, is also one of the basic technology of COINS, what we learn now block chain technology is separated from the COINS technology, using its features to ensure the security of information,
Sixth chapter mainly describes the immutability of block chain, and its a lot of equipment information can be recorded at the time of connection to ensure the integrity of the equipment, and other equipment can't through the way of forged IP address or injection of signature to connect to the network, but I didn't read this passage it describes information storage devices is what meaning,
Seventh paragraph mainly about the structure of the past for centralized cloud model, most of the computer connected to the server, but the connection of the equipment is becoming more and more data, if the high cost of management will lead to the centralized model, and security is not guaranteed, in centralized structure, if it is attacked or malfunction, can lead to problems all connected devices, and block chain technology can reduce costs, ensure safety,
Personal feel block chain technology includes the characteristics of dispersion and direct connectivity, in direct connectivity is similar to the biology between cells and the cell can pass information directly, without a similar total organs or mechanism of server, and there will be intelligent contract after connection to ensure safety, in this way can avoid because middlemen problems caused by information leakage, thus improve the security,
Don't understand is how a single block of safe protection?

CodePudding user response:

Don't need to consider a single node safety protection, the characteristics of chain block is the minority is subordinate to the majority, if 100 nodes in a node are malicious attacks wrote a wrong data, will be considered invalid block, to synchronize other nodes effectively block

that the data in a block, please? Is moved to the other block?

Good share! Thank you very much!

Discarded in the client's performance is synchronous data automatically after correction

CodePudding user response:

You ask should be data in a node, rather than a block of data

Good share! Thank you very much!

yes, the data is automatically updated
