# Assessment 12 #### Which capabilities does blockchain add to existing EDI implementations? (Select all that apply) * [ ] Faster document transmission between ERP systems * [x] Immutable audit trail proving what was originally agreed * [x] Automated execution of payments when smart contract conditions are met * [ ] Ability to format documents in standardized EDI message types * [x] Single source of truth all trading partners can verify independently * [x] Cryptographic verification of document authenticity **Notes to Learners** EDI already handles document transmission efficiently (A is false) and document formatting/standardization (D is false—that's EDI's core function). What blockchain adds are trust and verification capabilities EDI cannot provide: immutable records proving what was originally agreed (B), automated enforcement via smart contracts (C), shared truth eliminating conflicting versions (E), and cryptographic proof that documents haven't been tampered with (F). This complementary relationship explains why successful implementations combine both technologies. --- # 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.
