Answer

A blockchain is a decentralized ledger that is structured in chronological order and consists of blocks containing transaction information. Each block is linked to the previous block, creating an immutable record of transactions.

Transactions are verified in a blockchain through a process called "mining". A network of nodes validates transactions, ensuring that they comply with the rules of the blockchain and that there are no double spends. Once verified, transactions are grouped into a block and added to the blockchain.

Blockchain technology uses distributed ledgers and cryptography to create a secure and transparent transaction record system. It eliminates the need for a central authority and facilitates peer-to-peer transactions.

The present invention addresses the challenges of integrating and synchronizing data between blockchains and other computing resources, such as databases. It provides a secure and efficient method to identify and extract blockchain data for accounting, reporting, and other non-blockchain purposes.

A "deterministic key" refers to a key that can be derived from a parent key without additional information or randomness. The present invention uses deterministic keys to generate public keys associated with a specific classification or entity.

The classification scheme allows public keys to be grouped into different categories, such as entity identity or accounting type. This enables efficient retrieval and processing of transactions associated with a specific category.

In accounting, the present invention can simplify the generation of financial reports by classifying transactions according to entity or accounting type. By identifying and extracting relevant blockchain transactions, it can automate accounting processes and provide comprehensive financial records.

The present invention eliminates the need to manually search the entire blockchain to find relevant transactions by associating public keys with specific classifications or entities. This targeted approach reduces processing time and computing resources.

The lookup table stores the relationship between public keys and corresponding classifications or entities. It acts as an index that enables quick retrieval of public keys associated with a specific classification or entity.

The hierarchical entity structure described in this invention (such as a retail store and its point-of-sale terminal) uses deterministic key generation, where each child entity derives its key from the key of its parent entity. This hierarchical structure allows for efficient grouping and management of public keys and transactions.
