# Assessment 13 #### Your company receives an EDI 810 invoice from a supplier for $100,000. Three weeks later, the supplier claims it was actually $105,000. Both sides have database logs showing different amounts. With blockchain enhancement, how would this dispute be resolved? * [ ] Both parties submit their version to blockchain, which determines the average * [x] Blockchain shows the immutable record of what was originally transmitted, with cryptographic proof neither party could have altered * [ ] A smart contract automatically splits the difference and pays $102,500 * [ ] The blockchain administrator reviews both claims and makes a judgment **Notes to Learners** This illustrates blockchain's core value: eliminating "he said, she said" disputes. When the EDI 810 invoice was transmitted, blockchain recorded a cryptographic hash with timestamps and digital signatures. This creates an immutable record proving exactly what was agreed. Neither party can alter this retroactively—any attempt breaks the cryptographic signature. Unlike database logs which can be modified, the blockchain record is mathematically verifiable by both parties. There's no administrator making judgments (D is false), no averaging (A is false), and smart contracts don't make arbitrary decisions (C is false). Blockchain simply provides indisputable evidence, resolving disputes in seconds rather than weeks. --- # 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.
