Originally this idea came about to track government expenditure receipts and payments, but it can be leveraged for so much more: track signed contracts, screenshots, active states of websites, pictures or any other type of digital data.
What it does
While on a webpage, the user clicks a button through an extension plugin that sends the website data to our servers to store a screenshot state of the webpage. The URL or ID of the data store will be put on the blockchain along with a hash of the data to verify it's integrity.
How I built it
Looking to build it on the Ethereum Blockchain, most likely using solidity and the web3 protocol. Might leverage swarm and / or some sort of regular server / database system.
Challenges I ran into
Deciding to store the full image on the blockchain or just a URL address to the entry on a private server. The cost associated and business plan would dictate this decision.
Accomplishments that I'm proud of
Simplicity and ease of use for tracking full blown transaction receipts.
What I learned
How to leverage the Ethereum for smart contracts / saving data.
What's next for Archchain
Streamlining it and getting Government / Corporate procurement agents to use it.
