Blockchain for IoT Network Type Infrastructure

Glossary

Term DefinitionsBlockchain A content or data structure in the form of an immutable, append-only ledger containing sequentially ordered, verified blocks of electronic transactions that can be widely replicated. Block A container-type content or data structure that summarizes a list of electronic transactions and references (or "links") back to a previous block in the chain (also called a "parent" block) through the mathematically unique digital fingerprint of the previous block (called the block "hash"). Genesis Block The first block in a blockchain. Electronic Transaction A signed content or data structure that indicates an agreement, communication, record, or other electronic event. Miner A network node that verifies electronic transactions in a block by finding the correct solution to a mathematical problem or puzzle through repeated cryptographic hash operations, thereby earning rewards and/or fees. Mining The process by which a miner node verifies a block of electronic transactions for inclusion in a blockchain, usually by solving a blockchain problem or puzzle. Consensus Algorithm: An algorithm or method used to decide whether a block is a valid candidate for addition to a blockchain. Digital Currency Wallet: A container-type content or data structure that can store digital currency-related values ​​representing digital keys, addresses, signatures, etc. Smart Contract: An executable computer code and/or instruction that can facilitate, verify and/or enforce the negotiation and/or performance of an agreement. Sidechain: A blockchain that is independent of the main blockchain but interoperable with the main blockchain. Dynamic Pricing: A pricing strategy that adjusts prices in real time based on supply and demand. Short Answer Questions

Briefly describe the basic structure of a blockchain.

A blockchain is a chain structure consisting of multiple blocks connected together. Each block contains transaction data, a timestamp, and a hash value of the previous block. This chain structure and hash pointer ensure the immutability of the blockchain.

Explain the concept of "mining" in the blockchain.

Mining refers to the process of finding a hash value that meets certain conditions through calculation, thereby verifying transactions and adding them to the blockchain. Miners compete to calculate hash values ​​to obtain accounting rights and receive corresponding digital currency rewards.

How do IoT devices participate in blockchain mining?

IoT devices with sufficient computing power can use their idle computing resources to participate in mining. They can verify transactions, create blocks, and receive digital currency rewards.

How is blockchain used for identity authentication in the IoT environment?

IoT devices can write authentication information to the blockchain through digital signatures and public key encryption technology. Other devices can confirm the identity of the device by verifying the information on the blockchain.

What is a smart contract and what is its role in the IoT?

A smart contract is an automatically executed contract stored on the blockchain. It can pre-set transaction rules and automatically execute when conditions are met. For example, when the sensor detects that the temperature is too high, the smart contract can automatically trigger the air conditioner to turn on.

Briefly describe the importance of resource allocation in the IoT environment.

There are a large number of devices and limited resources in the IoT environment, such as bandwidth, storage space, and computing power. Effective resource allocation can ensure that resources are used reasonably, improve efficiency, and reduce costs.

How does blockchain promote resource allocation in the IoT?

Blockchain can create a decentralized resource trading platform. IoT devices can use digital currency to pay for resource usage, and smart contracts can automatically enforce resource allocation rules to ensure fairness and transparency.

Explain the role of dynamic pricing in IoT resource allocation.

Dynamic pricing can adjust resource prices based on real-time supply and demand. When resource demand increases, prices rise, and vice versa. This mechanism can incentivize efficient resource utilization and avoid waste.

How can IoT devices benefit from dynamic pricing in blockchain?

IoT devices can use dynamic pricing mechanisms to obtain resources at lower prices during periods of low resource demand, reducing operating costs.

How does peer-to-peer monitoring in IoT environments enhance security?

In peer-to-peer monitoring, IoT devices monitor each other, which can detect abnormal behavior faster. For example, if a device's behavior does not match its usual behavior pattern, other devices can mark it as a suspicious device.
