### Dataset Upload & Registration

#### 1. What types of files can I upload?

You can upload text-based files, including prompts, Q\&A pairs, transcripts, and spreadsheet-style data containing numbers and text. They must be csv, json or txt.

#### 2. Is there a size limit for my dataset upload?

Yes, each dataset upload must be under 50 MB. Larger files should be split into smaller uploads. Currently, users are limited to uploading 3-datasets per week. 

#### 3. How do I prove ownership of my dataset?

Ownership is proven by registering your dataset on-chain during the upload process. This creates a verifiable record linking you directly to your dataset.

#### 4. Can I update or delete my dataset after registering?

Registered datasets can be deleted in the "My Assets" page.

#### 5. Will my dataset be publicly accessible once uploaded?

No, datasets remain private unless explicitly shared or listed publicly by the dataset owner.

#### 6. How long does dataset registration take?

Registration typically takes a few minutes, but may vary slightly depending on blockchain network conditions.

#### 7. Can I transfer my NFT?

No - your ownership NFT is non-transferable.

#### 8. Why isn't the login working?

If you're having issues logging in with your wallet, ensure you are on the Sahara Testnet network.
