Centralized information displays blockchain information

Glossary

Term Definitions Blockchain An ever-expanding list of records/blocks that are linked and secured using cryptography. Distributed Ledger A ledger in a blockchain that is shared by all participants in that blockchain. Distributed Ledger Technology (DLT) Technologies that help address and overcome many types of deficiencies in traditional financial systems. Centralized data management systems store data in the form of a database and are managed by a single entity. Decentralized data management systems leverage the power and principles of blockchain to store data in a distributed or decentralized manner. Dynamic Form A dynamic user interface (UI) form that defines an interface for displaying data from decentralized and centralized data management systems. Metadata Information stored in a metadata repository or other mapping that stores information about individual object fields used across one or more applications. Virtual Objects represent virtual representations of data retrieved from a decentralized data management system. Merkle Tree A tree-like data structure used to efficiently index and retrieve blockchain data. Virtual Chain A mechanism that allows users to interact with a blockchain using SQL-like queries.

Answers to Quiz Questions

Centralized data management systems store data in the form of a database that is managed by a single entity, while decentralized data management systems utilize the power and principles of blockchain to store data in a distributed or decentralized manner. Centralized systems have a single point of control, while decentralized systems distribute data and control across multiple nodes.

The three main characteristics of blockchain are: immutability (data cannot be changed once recorded), security (data is protected using cryptography), and transparency (transactions are viewable by all participants).

Dynamic forms are used to define user interfaces to display data from decentralized and centralized data management systems. They allow developers to create flexible and dynamic interfaces that access and display data from multiple sources without having to understand the underlying data storage structure.

Metadata provides information about data fields from different data management systems. It allows dynamic forms to identify the source of the data (centralized or decentralized), apply the correct retrieval method, and correctly map the data to the user interface.

Records in a centralized data management system can be associated with records in a decentralized data management system by storing an external ID in its record that serves as a common identifier among records in the decentralized system. For example, a CRM record can store a customer UUID that is referenced in a blockchain transaction record, enabling the retrieval of related blockchain data when the CRM record is accessed.

Merkle tree indexes improve efficiency by providing an efficient addressing scheme for blockchain data. It allows specific blocks of data to be retrieved directly without searching the entire blockchain, thereby reducing retrieval time and improving performance.

The purpose of the Virtual Chain interface is to provide a user-friendly interface for interacting with the blockchain, enabling users to query and update blockchain data using a SQL-like query language, abstracting away the underlying blockchain complexity.

Due to the immutability of blockchain, the VirtualChain interface handles SQL UPDATE commands by inserting a new block containing the updated data, effectively replacing the previous values, rather than directly modifying the existing block. This process preserves the history of the blockchain while allowing for data modifications.

In the context of blockchain, a smart contract is a piece of code stored on the blockchain that automatically performs actions when predefined conditions are met. They facilitate decentralized and automated protocol execution without the need for intermediaries.

The VirtualChain interface manages synchronization with the blockchain by tracking committed and pending transactions. It provides feedback to the user based on the transaction status (pending or committed) and ensures that the user interface reflects the latest information on the blockchain. It handles any transaction rollbacks or invalidations due to lack of consensus, maintaining data integrity.
