Blockchain technology is a technology based on distributed ledgers. Through the combination of mathematical algorithms and real economic methods, a consensus mechanism is formed on the blockchain, so that blockchain technology has become a complete sharing economy in all aspects. frame.
With the breakthrough of blockchain technology, the traditional authentication method will be transformed into an authentication method, and finally the change of authenticity rather than authentication will be realized. Blockchain technology realizes information security, reliability and immutability through key control and encryption algorithms. The blockchain system allows users to trust the dimensions of artificial intelligence, transparency and consensus in the transaction process.
Blockchain technology is also known as distributed ledger technology in the IoT field. In the field of Internet of Things, the requirements for consistency and availability are relatively high, such as driverless cars. Since each node is completed by a node, each node can verify the location of its own vehicle without anyone’s permission and traffic information.
Since the blockchain technology can achieve a high degree of trust without the need for a third-party trust endorsement, this makes it more time-consuming and more labor-intensive for smart devices to set up smart devices. corresponding maintenance.
The use of blockchain technology can start the automatic identification, security, transaction verification and transaction management of devices from the bottom layer, and then realize the intelligence of the Internet of Things.
On the blockchain, anyone can access the data on the public blockchain, and everyone can issue transactions waiting to be written into the data in the blockchain. The data on the blockchain is stored in an open and transparent In the database, anyone can access and record data.
The blockchain system implements a non-tamperable and auditable ledger information library through the addition of private keys and the execution of smart contracts through cryptographic signatures. This technology does not depend on specific entities, but can also rely on some central institutions and authorities mechanism.
Blockchain technology ensures data integrity, non-tamperable data, non-forgery and traceability through cryptographic signature features.
Blockchain technology guarantees the security of data through the signature feature of cryptography, and permanently stores it in the blockchain in an irreversible manner, which can greatly reduce data duplication and interference.
Blockchain technology ensures the integrity of blockchain data that can be queried on each data node through the signature feature of cryptography, thereby improving the stability of the entire database.
