Short Answer Questions

Blockchain is a distributed ledger technology that records data in blocks, each of which contains a timestamp and a link to the previous block. Distributed ledgers are a technology that allows a network of multiple computers to maintain transaction records, and blockchain is one of its specific implementations.

Click-through agreements are common software licensing agreements that require users to indicate their consent by clicking an "OK" or "Agree" button. This type of agreement usually appears when users install software or use services online to ensure that users are aware of and agree to the relevant terms before use.

Smart contracts are a collection of code stored on the blockchain, including functions and data. When a message or transaction is received, the smart contract automatically executes the predefined logic and updates the data on the blockchain based on the results.

Blockchain version control systems use the immutability and transparency of blockchain to manage software licenses. Every time a user accepts new license terms, it is recorded on the blockchain, forming an immutable record that ensures the authenticity and traceability of the license agreement.

A light client node is a node with limited storage or bandwidth that only downloads block headers to verify transactions. Compared with full nodes that store a complete copy of the blockchain, light client nodes occupy fewer resources and are more suitable for resource-constrained environments such as mobile devices.

Merkle trees are a data structure used to efficiently verify transactions in blocks. It organizes the hash values ​​of all transactions into a tree structure, and the root hash value is stored in the block header. The integrity of any transaction in the block can be quickly verified by the root hash value.

The immutability of blockchain means that once data is recorded on the blockchain, it cannot be changed. This ensures the authenticity and reliability of the software license agreement, and no party can tamper with the content of the agreement afterwards.

The blockchain version control system verifies whether the user has accepted the software license terms by querying the records on the blockchain. The user's acceptance record will be stored in a block, and the system can confirm whether the user has accepted the terms by verifying the existence and integrity of the block.

Blockchain technology simplifies the record keeping process of software licenses by providing a secure, transparent and tamper-proof record keeping method. All records of license agreements are stored on the blockchain, which can be easily accessed and verified by any party without relying on centralized institutions or databases.

In addition to software licensing, blockchain version control systems can also be applied to digital identity management, supply chain management, intellectual property protection and other fields. Any application scenario that requires secure, transparent and traceable record keeping can benefit from blockchain technology.
