Technical Specifications

• Memory Structure: Each memory includes a content hash, title, description, type, unlock delay, anonymity flag, recipient (optional), and tags.
• Core Functions: Public functions include create-memory, claim-memory, like-memory, report-memory, and delete-memory, alongside read-only functions for retrieving memory details and user statistics.
• Error Handling: Comprehensive error handling is implemented for ownership validation, content validation, time-lock enforcement, and privacy controls.

Usage Examples

• Creating a Memory:

(contract-call? .memento-chain create-memory
    "QmHash..."                ;; content-hash
    "My First Memory"          ;; title
    "A special moment..."      ;; description
    "text"                     ;; memory-type
    u1440                      ;; unlock-delay (blocks)
    false                      ;; is-anonymous
    none                       ;; recipient (optional)
    (list "personal" "2024")   ;; tags
)
**Claiming a Memory:**
(contract-call? .memento-chain claim-memory u1)  ;; memory-id

**Security Considerations**
All user inputs are validated and sanitized.
Time-locks are enforced at the contract level to prevent premature access.
Privacy controls are strictly maintained to protect user data.
A content moderation system is in place to handle inappropriate submissions.
The contract can be paused in emergencies to prevent further interactions.

**Conclusion**
This pull request sets the foundation for a unique decentralized memory sharing platform. The robust feature set, combined with strong privacy and security measures, positions MementoChain as a reliable solution for users to preserve and share their cherished moments.
