On-Chain Snippet Timestamp Verification

[SudiptaPaul-31]

Issue: On-Chain Snippet Timestamp Verification

Description
Store snippet creation timestamps on the Stellar blockchain to provide proof‑of‑existence verification. This ensures ownership and originality of snippets by anchoring their creation time immutably on‑chain.

Acceptance Criteria

• Generate and store snippet creation timestamp on Stellar blockchain
• Map snippet ID ↔ transaction hash in database
• Provide API endpoint to verify timestamp authenticity
• Ensure immutability: once stored, timestamps cannot be altered
• Support verification flow for ownership and originality checks
• Handle error cases gracefully (failed transaction, invalid timestamp)
