1. The Basic Concept of Blockchain
Blockchain is a distributed data storage technology that combines peer-to-peer transmission, consensus mechanisms, and cryptographic algorithms to create a new type of application model. Essentially, blockchain is a decentralized database consisting of a series of interconnected data blocks generated through cryptographic methods. Each data block contains information about a network transaction, user to verify its validity (an anti-counterfeiting measure) and to generate the next block.
2. The Working Principle of Blockchain
The working principle of blockchain is based on the Byzantine Generals Problem, focused on how trading parties can reach consensus and prevent malicious damage without a trusted central node. Blockchain guarantees the continuity, reliability, and immutability of transactions through the following steps:
- Creating Transactions: A new transaction is initiated from the sender to the receiver.
- Broadcasting to the Network: The sender broadcasts the encrypted transaction record to the entire network.
- Information Verification: Receiving nodes verify the transaction record to ensure its authenticity.
- Packaging and Sealing: Once verified, the data is recorded in a time-stamped block.
- Consensus Algorithm: Nodes across the network execute a consensus algorithm on the recorded data blocks, accepting the block and incorporating it into the chain.
3. Characteristics of Blockchain
- Data Transparency: Data on the blockchain is open to all participants, enhancing trust.
- Data Traceability: Once data is recorded on the blockchain, it cannot be changed, ensuring traceability.
- Data Immutability: Blockchain uses cryptographic algorithms to ensure the security and immutability of the data.
4. Introduction to Notable Blockchains
- Bitcoin: Bitcoin is the first application of blockchain technology, serving as a decentralized digital currency that allows users to engage in peer-to-peer transactions without the need for intermediaries.
- Ethereum: Ethereum is a blockchain platform that supports smart contracts, allowing developers to build and deploy decentralized applications (DApps), thereby expanding the application's range of blockchain technology.
- Polkadot: Polkadot is a blockchain interconnection platform designed to connect different blockchain projects and facilitate communication and collaboration between them.
- Binance Smart Chain: This is a smart contract platform that competes with Ethereum by emphasizing transaction speed and low costs.
5. Introduction to XT Smart Chain
XT Smart Chain is a decentralized and energy-efficient public chain that is compatible with smart contracts and supports high-performance transactions. The inherent token of XT Smart Chain is XT, which adopts the HPoS consensus mechanism. It features low transaction costs, low transaction latency, and high transaction concurrency. The mission of XT Smart Chain is not only to serve as a public chain but also to focus on discovering and supporting high-potential developers and innovative projects. Leveraging the largest trading ecosystem globally, XT Smart Chain aims to become a hub for innovative technology and business, constructing a complete ecological cycle of technology development, application promotion, and trading.
