Answer

Blockchain is a decentralized distributed ledger for recording transaction data. Its key features include decentralization, transparency, security, and immutability.

A smart contract is a self-executing contract stored on a blockchain, whose terms are written in code. Unlike traditional contracts, smart contracts can be automatically executed without the intervention of a third party and ensure that all parties involved comply with the agreement.

Blockchain can record every link of a product from production to sales. The information of each link is recorded in a block and linked to the previous block to form an immutable record, thereby achieving transparent tracking of the product supply chain.

Blockchain can create timestamps and digital fingerprints for intellectual property, proving its originality and ownership, and preventing piracy and infringement.

Blockchain can create a decentralized energy trading platform, allowing individuals and businesses to trade energy directly without the involvement of intermediaries, improving efficiency and reducing costs.

Blockchain can store and verify identity information, users can control their own data and selectively share it with third parties, improve security and protect privacy.

A cryptocurrency wallet is a software or hardware used to store and manage cryptocurrency. It uses public and private keys to ensure that only authorized users can access and use funds.

Blockchain consensus mechanism is an algorithm that allows distributed network nodes to reach a consensus on the validity of a transaction. Common consensus mechanisms include proof of work (PoW) and proof of stake (PoS).

Challenges facing blockchain technology include scalability, regulatory uncertainty, and low public awareness.

Possible future applications of blockchain technology include decentralized finance, digital identity, supply chain finance, healthcare, etc.

Glossary

Term Definition Blockchain A decentralized distributed database used to record transaction information. Block The basic data unit in the blockchain, containing multiple transaction information. Smart Contracts are self-executing contracts stored on the blockchain, with terms written in code. Cryptocurrency is a digital or virtual currency that uses cryptographic principles to secure transactions and control the creation of currency. Cryptocurrency Wallet is software or hardware used to store and manage cryptocurrency. Public Key Cryptography is a cryptographic algorithm that uses public and private keys to encrypt and decrypt information. Consensus Mechanism is an algorithm that allows distributed network nodes to reach a consensus on the validity of a transaction. Proof of Work (PoW) is a consensus mechanism that requires network nodes to perform a large amount of computing work to obtain the right to create a new block. Proof of Stake (PoS) is a consensus mechanism that allocates the right to create a new block based on the amount of cryptocurrency held by network nodes. Decentralized Application (DApp) is an application built on a blockchain platform that does not rely on a centralized server.
