Blockchain Object Deployment and Cross-Chain Synchronization

Glossary

Term Definitions Blockchain Object An object deployed on a blockchain that can contain machine-readable instructions to manage its interactions and state. Smart Contract An implementation of a blockchain object whose machine-readable instructions define rules and automate the execution of interactions between participants. Event Interface System A system that facilitates the creation, deployment, and synchronization of blockchain objects, and provides interfaces for interaction with external systems. Components in the Event Stack system that receive, queue, and process events, including events from external systems and internal services. Context Patterns Patterns that describe blockchain object specifications and interaction constraints, such as states, actions, roles, and parameters. Profiles Instances of context patterns that contain custom parameters and types for specific blockchain objects. Blockchain Monitors Components that monitor blockchain updates and identify events related to specific blockchain objects. Blockchain Services Provides functionality for interacting with the blockchain, such as deploying blockchain objects and retrieving blockchain data. Hash Services Components that generate and manage data hashes for verification of data integrity and ownership. Identity Services Components that manage participant authentication and authorization, associating off-chain identities with on-chain identities. Cryptlets Code modules that execute in secure enclaves that can interact with the blockchain and process sensitive data. Oracle is a third-party service that provides external data to the blockchain, such as price information or weather forecasts. Short answer question

What is the main function of the event interface system? (2-3 sentences)

The main function of the event interface system is to create, deploy, and synchronize blockchain objects. It provides an interface that allows blockchain objects to interact with events on the event stack and other services in the system.

What is the role of the event stack? How does it interact with other components in the event interface system? (2-3 sentences)

The event stack receives, queues, and processes events from external systems (such as IoT devices) and internal services. It acts as an intermediary between events and blockchain objects, allowing services to access and process queued events.

What is the difference between context patterns and profiles? How are they used in the event interface system? (2-3 sentences)

The context pattern defines the general structure and interaction rules of blockchain objects, while the profile is an instance of the context pattern for a specific blockchain object, containing customized parameters and types. The system uses the context pattern to generate the profile, and uses the profile to manage and interact with blockchain objects.

What is a Cryptlet? How is it used in the event interface system? (2-3 sentences)

A cryptlet is a code module that is executed in a secure enclave and is used to process sensitive data or operations that require enhanced security. In the event interface system, cryptlets can be used to perform certain functions of blockchain objects, such as verifying transactions or managing access control.

How does the system use hashing to enhance data security and verifiability? (2-3 sentences)

How can the system use hashing services to generate hash values ​​for data and store the hash values ​​on the blockchain. Due to the one-way nature of the hash function, any change to the data will result in a change in the hash value, which can verify the integrity and tamper-proofness of the data.

What is the role of the identity service? How does it handle off-chain and on-chain identities? (2-3 sentences)

The identity service is responsible for verifying the identity of participants and managing their access rights. It associates the off-chain identities of participants (such as usernames and passwords) with their on-chain identities (such as public and private key pairs) so that they can interact with blockchain objects.

How does the system handle different states and state transitions of blockchain objects? (2-3 sentences)

The system uses the context mode and the state diagram defined in the configuration file to track and manage the states and state transitions of blockchain objects. The state diagram defines the allowed state transitions and the allowed actions in each state, ensuring that the blockchain objects operate according to predefined rules.

Explain the "master-slave" relationship between blockchain objects 108X and 108Y. (2-3 sentences)

In a master-slave relationship, one blockchain object (master) controls the state transitions of another blockchain object (slave). The slave blockchain object can only change its state after receiving a confirmation message from the master blockchain object.

Describe how the system uses the event stack and blockchain monitor to communicate between blockchain objects and external systems. (2-3 sentences)

External systems send events to the event stack, which queues the events and passes them to the blockchain service. The blockchain service deploys the events to the blockchain, which can be received and processed by the blockchain objects. The blockchain monitor tracks blockchain updates and notifies the system of events related to specific blockchain objects.

How does the system use context information to generate user interfaces? (2-3 sentences)

The system uses context patterns and profiles to determine the user's role, current state, and allowed actions. It then uses this information to generate a customized user interface that displays only information and actions relevant to the user.
