Deploy Smart Contract per Network to Manage Chain of Memories

[Xm0onh]

We need to deploy a smart contract per network to manage the last recorded hashes. This will help maintain consistency and verifiability across different networks.

One open question:

• Should the experience explicitly reference where the CID can be found (e.g., Taurus or mainnet)?

Next Steps:

• Define the structure and logic for deploying the smart contract per network.
• Decide how and where to reference CID locations.
• Reorganize data within the experience to improve clarity and usability.
