#### **Glossary of Technical Terms**

* **Blockchain**: A decentralized, immutable ledger that records transactions across a network of computers. ([Source](https://us.aicpa.org/content/dam/aicpa/interestareas/informationtechnology/downloadabledocuments/blockchain-universal-glossary.pdf))
* **Smart Contract**: Self-executing contracts with the terms directly written into code, running on a blockchain. ([Source](https://www.blockchain-council.org/blockchain-glossary/))
* **Decentralized Application (DApp)**: An application that operates on a decentralized network, combining smart contracts and a frontend user interface. ([Source](https://www.theblock.co/glossary))
* **Federated Learning**: A machine learning technique where multiple entities collaboratively train a model without sharing their data, maintaining data privacy. ([Source](https://en.wikipedia.org/wiki/Federated_learning))
* **InterPlanetary File System (IPFS)**: A peer-to-peer protocol for storing and sharing data in a distributed file system.
* **Zero-Knowledge Proof**: A cryptographic method by which one party can prove to another that a statement is true without revealing any additional information. ([Source](https://en.wikipedia.org/wiki/Zero-knowledge_proof))
* **Layer-2 Solution**: A secondary framework or protocol built on top of an existing blockchain to improve scalability and transaction speed. ([Source](https://www.theblock.co/glossary))
* **Consensus Algorithm**: A mechanism used in blockchain networks to achieve agreement on a single data value among distributed processes or systems.
* **Node**: A participant in a blockchain network that maintains a copy of the ledger and may validate transactions. ([Source](https://us.aicpa.org/content/dam/aicpa/interestareas/informationtechnology/downloadabledocuments/blockchain-universal-glossary.pdf))
* **Byzantine Fault Tolerance**: The ability of a distributed network to reach consensus despite some nodes acting maliciously or failing. ([Source](https://www.blockchain-council.org/blockchain-glossary/))
