### Prize Bounty
$750 in ETH
### Challenge Description
As well as allowing permanent, on-chain storage of large documents, Arweave can also provide cheap, permanent and verifiable timestamping of data that remains private to the user.
For example, [Chronolock](https://arweave.net/6VkUYorRUkLRtBigUWPErwi95SJqeW6Z07sZemDDGiM) is a permaweb app that allows users to timestamp their documents into the Arweave, without revealing their contents to others.
This prize is for the best service that users allows users to CC or FWD an email to an address and have a hash of it permanently stored into the blockweave -- providing a valuable utility for those that wish to prove the contents of messages they have sent or received.
### Submission Requirements
You should aim for a minimal viable product that an end-user could reasonably get started with. This service will inevitably need some centralised component in order to hook into email services, but as much of the system should be decentralised as possible.
### Submission Deadline
July 10th, unless otherwise specified
### Judging Criteria
Best submission that an end-user could reasonably start to use
### Winner Announcement Date
July 12th, unless otherwise specified
