Answer

Blockchain is a distributed ledger database, essentially an online transaction record. In the financial sector, it is used to record and track transactions in digital currencies such as Bitcoin.

Blockchain technology is based on trust and transparency. Each transaction requires verification by multiple participants in the network to ensure the accuracy and reliability of the record.

Self-driving cars rely on the accuracy of large amounts of data to make driving decisions. Data corruption or tampering can lead to serious accidents.

Blockchain protects data security through encryption and distributed storage. Each data block is linked to the previous block, and any tampering will be immediately discovered.

Smart contracts are pre-written agreements stored on the blockchain that automatically execute the terms of a transaction. They ensure transparency and automatic execution of transactions.

"Miners" are computers that participate in validating and adding new blocks to the blockchain. They earn rewards by solving complex computational problems.

Data blocks typically contain a block header (containing information such as timestamp, hash value of the previous block, etc.) and a payload (containing transaction data).

Hashing is an algorithm that converts data of arbitrary length into a fixed-length string. In data blocks, hashing is used to ensure the integrity of the data, and any changes will result in changes in the hash value.

Data on the blockchain is difficult to tamper with once it is added to the blockchain. This is because each block is linked to the previous block, and any changes require changes to all subsequent blocks.

The advantages of using blockchain technology in vehicles include:

Improve data security and transparency

Facilitate secure communication between vehicles

Simplify data sharing and transactions
