Object-Verified Blockchain Account Methods and Systems Study Guide

Glossary

Term DefinitionsBlockchainA decentralized, immutable, distributed ledger technology for recording transaction data.CryptocurrencyA digital or virtual currency that uses cryptographic principles to secure transactions and control currency creation.MasternodeA special type of cryptocurrency node that runs 24/7 and provides specific services, such as supporting decentralized applications.Decentralized API (DAPI)An application programming interface that allows client applications to interact with the blockchain without directly connecting to the peer-to-peer network.SchemaA formal specification that defines data structures and validation rules to ensure the consistency and integrity of objects stored in the system.ArbitrationA group of masternodes that collectively reach consensus on the validity and consistency of data.ConsensusThe process by which all participants in a blockchain network reach agreement on the history of transactions.State transitions represent the change of account data from one state to another, where each transition references the last transition agreed to by the network consensus.ObjectAn off-chain data structure stored on the blockchain that represents data for a user or application.AttributeA single data field contained in an object, such as a username or email address.Application SchemaA custom schema defined by third-party applications that extends the core system schema to meet their specific needs. Payment objects represent objects of blockchain data, such as blocks, transactions, and addresses. Superblocks are special blocks used to pay participants who contribute to the network, such as masternode operators and budget proposal voters. Masternode shares are a mechanism that allows account holders to collectively fund the operation of masternodes, allowing them to share in the resulting rewards. Governance refers to the process of community management and decision-making, such as voting on budget proposals.

Answers

Masternodes are special nodes that provide additional services, such as data storage and validation. They support decentralized applications by providing reliable infrastructure and participating in arbitration to validate data.

A decentralized API simplifies interaction with the blockchain by hiding the complex peer-to-peer network layer from users. It acts as an intermediary between client applications and the network, enabling users to access blockchain features more easily.

A schema is a blueprint that defines data structure and validation rules, ensuring that all objects stored in the system follow predefined structures and constraints. It helps maintain data consistency and integrity.

A quorum is a set of master nodes responsible for verifying the validity of data. For data to be accepted, a majority of the members of the quorum must reach a consensus on its validity, which enhances security and prevents malicious activities.

A state transition represents a change made to account data, where each transition is linked to a previous state. Objects are stored in state transitions, reflecting the latest state of account data.

System schemas define the basic rules and structure that all objects must follow, while application schemas extend system schemas to include application-specific rules and data structures.

Payment objects are representations of blockchain data, such as blocks, transactions, and addresses. They allow applications to access and interact with blockchain data in a structured way.

Masternode shares enable users to collectively contribute to running a masternode, thereby sharing the costs and rewards. This enables more users to participate in masternode operations.

Superblocks are used to distribute rewards to participants who participate in the governance of the system, including masternode operators and users who vote on budget proposals.

The system relies on masternode voting to handle malicious activity on an account. If a certain percentage of votes is reached, the malicious account can be closed to prevent further abuse.
