Execution-Time Evidence Objects (ETEOs) for Gambling & Gaming Payment Integrity

This technical specification defines Execution-Time Evidence Objects (ETEOs) for gambling and gaming environments where payment integrity, dispute resolution, and regulatory defensibility depend on non-reconstructive records.The specification describes a method for generating execution-time, chain-of-custody evidence at the moment wagers, outcomes, settlements, or operational actions occur, rather than relying on reconstructed logs or post-hoc data aggregation.ETEOs are designed to support audit-defensible dispute handling across:• Player chargebacks and payment disputes• Operator-processor settlement reconciliation• AML, responsible gaming, and regulator inquiries• Platform integrity and third-party reviewThe framework prioritizes privacy-preserving capture, cryptographic linkage, and contemporaneous evidence generation to reduce reliance on narrative explanations or reconstructed records in high-risk payment and compliance workflows.
