[FEAT] - Build Init Setup For IPFS Upload

[0xBoji]

Description
Implement the initial setup for uploading and retrieving files using IPFS to support decentralized storage for research proposals, profiles, and DAO metadata.

Tasks

• 1. Integrate IPFS API:

• Set up connection to an IPFS node (e.g., Infura, Pinata, or local node).

• Add configuration for IPFS API keys and endpoints in .env.local.

• 2. Build Upload Functionality:

• Implement a utility function to upload files to IPFS.

• Return the IPFS hash (CID) after a successful upload.

• 3. Build Retrieval Functionality:

• Add a function to retrieve files using their IPFS hash.

• Handle error cases for invalid or unavailable CIDs.

• 4. UI Integration:

• Create a simple upload interface with drag-and-drop or file selection.

• Display the generated IPFS hash and a preview of uploaded content.

• 5. Testing:

• Verify successful file uploads and retrievals.

• Test error handling for invalid uploads.

Acceptance Criteria

• Users can upload files and receive an IPFS hash.
• Uploaded files are retrievable using the hash.
• Upload functionality is secure and handles errors gracefully.

Priority: Medium
Target Milestone: MVP Version

Notes: Focus on a scalable setup compatible with future IPFS integrations for proposals, metadata, and profiles.
