# Assessment 3 #### What is the fundamental difference between a database record and a blockchain record? * [ ] Blockchain is faster than databases * [ ] Blockchain can be altered by its owner, databases cannot * [x] Blockchain records are tamper-proof and independently verifiable; database records require trusting whoever controls the database * [ ] Blockchain is newer technology than databases **Notes to Learners** This is the core insight. Databases require trust—you must trust whoever controls the database hasn't altered records. Blockchain provides mathematical proof—records are cryptographically secured and tampering is detectable by anyone. This is why blockchain solves the trust gap: consumers can verify your sustainability claims by checking the blockchain themselves, without needing to trust your internal systems. Every other feature of blockchain (transparency, traceability, tokenization) flows from this fundamental capability: the ability to prove something without requiring trust. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
