Distributed Ledger Declarative Smart Actions

Distributed Ledger Declarative Smart Actions

Glossary

Term Definitions Blockchain A distributed ledger technology (DLT) that records transactions in a secure, transparent and tamper-proof manner. Distributed Ledger Technology (DLT) A technology that replicates and shares data across multiple nodes or computer networks without the need for a central authority. Smart Contract A program that automatically executes and enforces the terms of an agreement on a blockchain. Declarative Smart Action A custom action defined by a user that extends the basic functionality of a blockchain and captures additional transaction information. Blockchain Service Interface A gateway provided by a host organization that allows tenants to interact with a blockchain. Host Organization An entity that provides and manages a cloud computing environment, including blockchain services. Tenant A customer or organization that uses services provided by a host organization. Base Function A set of predefined blockchain actions that are accessible to any node participating in a blockchain. Custom Function A user-defined blockchain action that is built using base functions and additional data fields. Smart Contract Executor (Validator) A component that validates a smart contract associated with a declarative smart action and executes its logic. Metadata A data that provides information about the data but is not the data itself. In this context, metadata is used to define and store information about declarative smart actions. Digital Twin A digital representation of a physical asset or product. Certificate of Authenticity A digital document that verifies the authenticity of a digital twin. Globally Unique Identifier (GUID) An identifier used to uniquely identify a digital twin stored on a blockchain. Merkle Tree Index A data structure that allows for efficient verification and retrieval of blockchain data. Sidechain An independent blockchain linked to a main blockchain that allows for interoperability between blockchains.

Answer

Blockchain is a type of DLT that records transactions in a secure, transparent, and tamper-proof manner. DLT is a method of replicating and sharing data across multiple nodes or computer networks without the need for a central authority. All blockchains are DLTs, but not all DLTs are blockchains.

The purpose of declarative smart actions is to extend the basic functionality of blockchains, enabling users to define custom actions and capture additional transaction information. They provide a more flexible and versatile way to use blockchains for a variety of use cases.

Base functions are a set of predefined blockchain actions that are accessible to any node participating in a blockchain. Custom functions are user-defined blockchain actions built using base functions and additional data fields, providing customized functionality for specific use cases.

Smart contracts play a vital role in the context of declarative smart actions, acting as an enforcement mechanism for capturing additional data. They verify that the provided data fields meet predefined conditions, ensuring data integrity and compliance.

The host organization uses the Blockchain Service Interface as a gateway to allow tenants to interact with the blockchain. The interface provides a simplified way to access blockchain functionality, submit transactions, and manage blockchain-related operations without requiring tenants to manage their own blockchain infrastructure.

Certificates of authenticity are embedded in the digital twin to ensure its authenticity. This certificate acts as a digital document, verifying that the digital twin is an authentic and authorized representation of the physical asset or product it represents.

GUIDs are used to uniquely identify digital twins on the blockchain. This unique identifier helps track ownership of the digital twin, access data associated with it, and ensure unambiguous references to the digital twin between different parties in the blockchain ecosystem.

Merkle tree indexes play a vital role in blockchain data retrieval by creating a compact representation of blockchain data. This index allows efficient verification and retrieval of specific data without traversing the entire blockchain, making data retrieval faster and more efficient.

Sidechains are independent blockchains that are linked to the main blockchain, allowing for interoperability between blockchains. They provide an additional layer for experimenting with new features, dealing with scalability issues, and enhancing privacy without compromising the security of the main chain.

Declarative smart actions based on DLT enhance data auditability by allowing for the capture of additional transaction information. Unlike traditional blockchain transactions that only record basic transaction data, this approach ensures that comprehensive contextual information about each transaction is captured, thereby improving transparency and accountability.
