No you do not need Ether to use DocStamp. We accept funds in USD.
No. We do not store the contents of your document anywhere.
We store a hash (SHA-1) of your email along with your document hash. This is to prevent someone else from claiming ownership of a registered document in case of theft.
Absolutely! We only store the cryptographic hash of your documents. The hash is calculated on your computer and serves as a fingerprint for your document. It is impossible to reconstruct your document from this hash.
DocStamp is implemented using a smart contract on the Ethereum blockchain. When you record a document using DocStamp, you are guaranteed that this record is immutable. This information cannot be lost, it cannot be modified even by governments and you can always verify this information even if DocStamp is down
Yes. Scan a copy of the physically signed contract and DocStamp it!
When you have sensitive documents that nobody should see. Sensitive contracts, patent related documents.
When you need to timestamp data so that you can later prove that you possessed it.
When you need to preserve data integrity - The hash (SHA-256) that we compute maintains a fingerprint of your document. This changes with any modification to the original document.
When you want the peace of mind that your document record is stored on a decentralized system that prevents any manipulation.
When you want to save yourself a trip to the notary.
