Term DefinitionsNon-Fungible Token (NFT)A digital asset stored on a blockchain that represents a unique, non-interchangeable item, such as a digital artwork, collectible, or virtual item.Internet of Things (IoT)A network of physical objects (e.g., devices, vehicles, buildings) that connect and exchange data over the Internet.Smart ContractA piece of code stored on a blockchain that automatically executes the terms of an agreement when predefined conditions are met.Electronic Tongue SensorAn electronic device that mimics the human sense of taste and is used to detect and analyze the chemical composition of liquids.BlockchainA decentralized distributed ledger that records transactions and tracks assets with transparency, security, and tamper-proof features.EthereumA decentralized blockchain platform with smart contract capabilities that allows the development and deployment of decentralized applications (DApps).Ethereum Virtual Machine (EVM)A virtual machine used by the Ethereum network to execute smart contracts.Topology OptimizationA design method used to optimize the distribution of materials for optimal performance, often used to create lightweight and efficient structures.Lattice StructureA three-dimensional open-cell structure composed of repeating units or lattices, often used in additive manufacturing or 3D printing. Piezoelectric material A material that generates an electric charge under mechanical stress and vice versa, commonly used in sensors and actuators. Two-phase commit A protocol used in distributed systems to ensure atomicity, in which all participants must agree to any change before it takes effect. Patricia tree (Trie) A tree-like data structure used to efficiently store and retrieve data, commonly used in routing and database indexing. Merkle tree A tree-like data structure used to efficiently verify the integrity of large data sets, commonly used in blockchains and peer-to-peer networks. Digital signature An electronic signature that uses cryptography to verify the authenticity of a digital message or document. Public key cryptography A cryptographic system that uses key pairs (public and private keys) for encryption and decryption. Hash function A function that maps data of arbitrary size to a fixed-size hash value, used for data integrity verification and digital signatures. Physically unclonable function (PUF) A physical structure that generates a unique identifier based on physical properties (such as small variations in the manufacturing process). Rotating credit union (RCA) A savings and credit plan in which a group of individuals or families regularly contribute to a common fund and receive the full amount in rotation. Underwriting criteria A criterion that lenders use to assess a borrower’s credit risk and determine whether to approve a loan. Social graph A graphical representation that describes individuals and their relationships in a social network. Credit scoring model A statistical model used to predict the likelihood that a borrower will repay a loan based on their credit history and other factors. Short Answer Questions

What is an NFT and how does it relate to IoT devices?

An NFT is a unique digital asset stored on a blockchain that can represent digital ownership or specific functionality of an IoT device. For example, an NFT can represent ownership of a smart home appliance and be stored on a blockchain for secure and transparent transfer of ownership.

What are the potential uses of electronic tongue sensors in smart sports equipment?

Electronic tongue sensors can be used to analyze the composition of sweat, providing information about an athlete’s hydration, electrolyte balance, and muscle fatigue. This data can be used to optimize training regimens and improve performance.

Explain the role of topological optimization and lattice structures in designing sports equipment.

Topological optimization helps identify areas in the design space where material can be removed or added to minimize weight while maintaining performance. Lattice structures are lightweight and strong and can be customized to the athlete’s needs, providing targeted support and cushioning.

How do smart contracts facilitate secure transactions on a peer-to-peer sports equipment rental platform?

Smart contracts can automatically enforce the terms of a rental agreement, such as payment, rental period, and equipment availability. This ensures transparency, security, and automation of transactions, reducing the need for middlemen.

How does the two-phase commit protocol ensure transaction integrity in blockchain-based sports equipment transactions?

Two-phase commit ensures that both the buyer and seller agree to the terms of the transaction before it goes into effect. This prevents partial transactions or situations where one party refuses to fulfill its obligations.

What is the role of Patricia trees in managing a blockchain-based sports equipment ecosystem?

Patricia trees are an efficient data structure for storing and retrieving account information, such as balances, transaction history, and ownership details. Its efficient search and insert operations make it suitable for managing large data sets.

How do digital signatures verify the authenticity of data collected by IoT sports equipment?

Digital signatures enable users to cryptographically verify the origin and integrity of data. This ensures that the collected data has not been tampered with and is indeed from a legitimate IoT device.

Explain the use of Physical Unclonable Functions (PUFs) in sports equipment authentication.

PUFs can generate unique identifiers based on their unique physical properties. This can be used to create a tamper-proof authentication system for sports equipment, preventing counterfeit products.

How can Rotating Credit Unions (RCAs) provide an alternative financing model for the purchase of sports equipment?

RCAs allow groups of individuals to save together and take turns receiving the entire amount. This can help people with limited credit histories or who don’t have access to traditional financing options purchase sports equipment.

Discuss how social graph data can be used to assess the creditworthiness of borrowers on peer-to-peer sports equipment lending platforms.

Social graph data, such as connections, reputation, and online activity, can be used to assess the creditworthiness of borrowers. Analyzing social relationships and online behavior can provide insight into their financial responsibility and likelihood to repay the loan.
