Transaction Ledger Specification

As an engineer for a timeshare accounting system, it is crucial to create a transaction ledger to record all actions performed by users related to token-based transactions. This ledger will be pivotal for ensuring transparency, accuracy, and integrity in the accounting process, and will serve as an immutable record that can be audited. It should support the creation, transfer, and exchange of timeshare tokens, in addition to allowing for secondary market transactions.

Acceptance Criteria

• [ ] The ledger can record token creation with relevant timeshare details.
• [ ] The ledger can record token transfers between users.
• [ ] The ledger can record exchanges or trades of tokens on the secondary market.
• [ ] The ledger entries must include timestamp, transaction type, parties involved, and the number of tokens.
• [ ] The ledger must provide a mechanism to verify the integrity of the recorded data.
• [ ] The ledger must be queryable for transaction history by user or token ID.
• [ ] The system must prevent the creation of fraudulent transactions in the ledger.
• [ ] The system should facilitate the generation of reports for auditors and stakeholders.
