Autonomous Device Digital Asset Trading System

Glossary

Autonomous device: A device equipped with one or more processors and non-volatile computer-readable memory, in which computer-readable instructions are stored for performing predefined tasks without human intervention. Digital Asset: An asset in electronic form that can be protected using cryptography and traded digitally. Blockchain: A distributed database that records transactions and maintains them in a secure, transparent, and tamper-proof manner. Smart Contract: A program stored on a blockchain that is automatically executed when predefined conditions are met. Token: A smart contract that represents a digital asset that can represent a variety of things, such as points, coupons, or physical objects. Digital Asset Exchange: A platform that provides digital asset trading services, allowing users to buy and sell digital assets such as Bitcoin and Ethereum. Digital Wallet: Software or hardware used to store, send, and receive digital assets. Hash Algorithm: An algorithm that converts data of any length into a fixed-length hash value. Hash Chain A series of interrelated hash values, where each hash value depends on the previous hash value. Asymmetric Key Pair A pair of keys consisting of a public key and a private key, the public key can be made public, while the private key must be kept secret. Digital Signature An electronic signature created using a private key that can be used to verify the authenticity and integrity of a message. Short Answer Questions

1. What is an autonomous device? How is it different from a traditional device?

Autonomous devices are devices equipped with processors, sensors, and software that are able to perform specific tasks without human intervention. Unlike traditional devices that require human intervention, autonomous devices can make decisions and take actions autonomously based on pre-programmed instructions or through machine learning algorithms.

2. What are digital assets? Please list three common digital assets.

Digital assets are assets represented and secured using digital technology and can be traded electronically. Common digital assets include Bitcoin, Ethereum, and Litecoin.

3. What role does blockchain technology play in digital asset transactions?

Blockchain technology provides a decentralized, tamper-proof platform for digital asset transactions. It records all transaction histories and maintains them through a distributed network, ensuring the security and transparency of transactions.

4. What is a smart contract? How does it apply to autonomous device transactions?

A smart contract is a program stored on a blockchain that is automatically executed when preset conditions are met. In autonomous device transactions, smart contracts can be used to automate transaction processes, for example, when an autonomous device needs to be refueled, a smart contract can automatically complete the payment process.

5. What are tokens? How are they different from digital assets?

A token is a smart contract that represents a digital asset and can represent a variety of things, such as points, coupons, or physical objects. The difference between them and other digital assets is that tokens are usually based on existing blockchain platforms, such as Ethereum, while digital assets can have their own independent blockchain.

6. What are the functions of a digital asset exchange?

A digital asset exchange provides users with a platform to buy and sell digital assets. It acts as an intermediary between buyers and sellers, matching transactions and ensuring the smooth progress of transactions.

7. What is a digital wallet? What types are there?

A digital wallet is software or hardware used to store, send, and receive digital assets. Common types of digital wallets include hot wallets (online wallets) and cold wallets (offline wallets).

8. How do hash algorithms play a role in autonomous device authentication?

Hash algorithms can convert data of any length into a fixed-length hash value, which is used to create a unique device identifier. By verifying the hash value, the identity of the device can be confirmed to prevent fraud.

9. What is a hash chain? How does it enhance the security of autonomous device transactions?

A hash chain is a series of interrelated hash values, where each hash value depends on the previous hash value. By using a hash chain, a tamper-proof transaction history can be created to ensure the integrity and non-repudiation of transactions.

10. What is the role of asymmetric key pairs in autonomous device transactions?

Asymmetric key pairs consist of a public key and a private key, where the public key is used to encrypt data and the private key is used to decrypt data. In autonomous device transactions, asymmetric key pairs are used to create digital signatures to verify the authenticity and integrity of transactions.
