Term DefinitionsBlockchainA distributed database that maintains data in the form of a growing chain of records called blocks. Each block contains a timestamp and a link to the previous block, and can store transactions or other types of information.Consensus SystemA mechanism used in a blockchain network to ensure that all nodes agree on the order of transactions.Consensus NodeA computer device that participates in the consensus system, maintains a copy of the blockchain, and verifies blocks and data in the blockchain.Leader Consensus NodeA node responsible for building new blocks and distributing them to other consensus nodes for consensus.Sequential DataData that is arranged in time or other order, such as system log entries, securities transactions, etc.Data SourceA device or entity that generates sequential data.Source TimeA timestamp assigned to each part of sequential data by the data source.Source IdentifierA unique identifier used to identify the source of sequential data.ThreadAn independent process running on a consensus node that generates and manages a single blockchain. Block Height The sequential position of a block in a blockchain. Block Header Hash A unique identifier generated by applying a hash function to a block header, used to identify a block. Previous Block Header Hash The block header hash of the previous block contained in the current block header, used to establish links in a blockchain. Audit Computing Device A device used to access and analyze blockchain data for auditing purposes.

Answer to the short answer question

Blockchain is a distributed database that maintains data in the form of a growing chain of records called blocks. Unlike traditional databases, the data of blockchain is distributed across multiple nodes, and encryption technology is used to ensure that the data is secure and immutable.

The consensus system is used to ensure that all nodes in the blockchain network agree on the order of transactions. It allows distributed decision-making without a central authority and ensures that all nodes maintain the same copy of the blockchain.

The leader consensus node is responsible for building new blocks and distributing them to other consensus nodes to reach a consensus. It collects sequential data, packages it into blocks, and broadcasts the blocks to the network.

Sequential data is stored in blocks in the blockchain. Each block contains multiple sequential data parts that are arranged in time or other order.

The source time indicates when the data source created a specific part of the sequential data, while the source identifier uniquely identifies the data source. This information is essential to determine the order and source of the sequential data.

Sequential data in different blockchains is linked by copying the last data part (or part of it) of the previous block in the first entry of the subsequent block. This mechanism preserves the order of data across multiple blockchains.

Using multiple blockchains can increase the total throughput of storing sequential data. By generating blockchains in parallel, the system can record data faster and reduce the load on a single blockchain.

Leader consensus nodes manage the generation of multiple blockchains by running multiple threads simultaneously. Each thread is responsible for generating and maintaining a separate blockchain, enabling parallel processing.

Audit computing devices can access and analyze blockchain data for audit purposes. It can read the blockchain, extract sequential data, and verify the integrity and sequence of the data.

Blockchain technology can be applied to a variety of fields, including supply chain management, healthcare, identity management, voting systems, and more. Its decentralized, transparent, and secure characteristics make it suitable for a variety of applications that require data integrity and trust.
