Short Answer Questions

What is the role of the master chain in a blockchain system?

The master chain is responsible for managing how data is distributed across different partition chains. It stores the partitioning rules that determine which data should be stored on which partition chain.

What is the purpose of partition chains?

Partition chains are designed to improve the scalability and throughput of blockchain systems. Each partitioned chain stores only a subset of data, which reduces the burden on a single blockchain and allows transactions to be processed in parallel.

How do cross-chain transactions differ from traditional blockchain transactions?

Cross-chain transactions involve multiple blockchains, while traditional blockchain transactions involve only a single blockchain. Cross-chain transactions require retrieving data from multiple blockchains and executing transaction logic on multiple blockchains.

How does the transaction router decide which partitioned chain to route a transaction to?

The transaction router reads the partitioning rules stored on the main chain and determines which partitioned chain to route the transaction to based on the transaction content (e.g., the user ID involved, the asset ID, etc.).

What role does the cross-chain processor play in cross-chain transactions?

The cross-chain processor is responsible for executing cross-chain transactions, including retrieving data from different partitioned chains, executing transaction logic, and updating the results to the relevant blockchains.

What role does the hybrid chain play in the blockchain system?

The hybrid chain is used to store the results of cross-chain transactions, as well as other information related to cross-chain transactions, such as the blockchains involved in the transaction, the data range, etc.

What is the role of smart contracts in blockchain systems?

Smart contracts are codes stored on the blockchain that are automatically executed when preset conditions are met. In this system, smart contracts can be used to implement functions such as partitioning rules, transaction routing logic, and cross-chain transaction logic.

How does a blockchain system handle a large number of concurrent transactions?

By partitioning data onto multiple partition chains, a blockchain system can process transactions in parallel, thereby increasing the throughput of the system.

How does a blockchain system ensure data security?

Blockchain systems use cryptography to ensure the security and immutability of data. Each block is linked to the previous block through a hash function, and any tampering with the data will be detected immediately.

How does a blockchain system achieve decentralization?

Data in a blockchain system is stored on multiple nodes rather than centrally on a single server. This makes it impossible for any single node to control the entire system, thereby achieving decentralization.
