CardanoWall, new levels of PoE

CW lets the authors anonymously prove the authorship of PoE. It also encrypts files in a browser and stores a copy in the CW public storage.

15+ years of experience as a SW Architect and Engineer. 4+ years of deep experience working in the online data preservation/recovery field.

I already created CardanoWall.com, that provides a working solution.

Level 1 (rolled-out):

There is a concept called Proof of Existence. A hash value of digital data, such as a file, can be included in a transaction. Since the data cannot be changed once on the blockchain, nothing can be added retrospectively, and this hash value cannot be faked. This means that a message with a hash value is proof that your data existed when the message was sent. The blockchain acts as a cryptographic notary who is impartial and inflexible. The algorithm for obtaining a hash sum is a one-way function. You cannot get back the contents of your data from it, and you do not disclose the contents of the data to it.

Level 2 (rolled-out):

I went much further and developed the idea of "Proof of Existence" with several new layers. Utilizing cryptography capabilities, you can now anonymously sign your Proof of Existence and, if necessary, prove in court that the data is yours, you are the owner of the private key, and the author of the signed message.

Level 3 (rolled-out):

But this is just the beginning. Using these same solid cryptographic techniques, you can encrypt your data and store it on the public internet. Only you, as the private key owner, can decrypt the data or get a long and complex password to decrypt it. In case of data loss, you have the option to recover the data. Since each file is encrypted with its own secure password, you can share the password from a specific file. Working with keys, encrypting and decrypting data takes place exclusively on your side, in your browser. The keys and the content of the original data are never transmitted to the server. All used encryption and hashing algorithms are reliable and safe to use. Whether you are a book author, musician, photographer, artist, designer, or even a business working with important documents, CardanoWall can help you create concrete proof of your work.

A new feature allows the creation of PoE for any internet page. CardanoWall creates a full-size screenshot + WARC file containing all internal and external elements like images, CSS styles, JS scripts, etc. CardanoWall takes care of the technical part and loads all files in the client's browser to create a PoE record with an additional option to include encrypted versions to CW storage. This feature helps proving the usage of copyrighted materials without permission. It is in demand among lawyers for the protection of intellectual property rights. People can also monitor and save fake news on the internet or store a copy of new official information posted on government websites.

Level4 (in progress):

Currently, I am working on additional features with a clear vision about the next fourth level of PoE that will enable secure and encrypted communication on the Cardano blockchain between parties or additional applications. It will bring more real-life usage and attract businesses to use CW for providing bonus materials tied to a purchased product with an included private key.

Funding

At the moment, I am doing all the back-end/front-end/marketing work myself. Additional funding will allow me to allocate more time to the CardanoWall project, hire a JS developer to improve in-browser encryption of large files, hire advisors to fulfill criteria from courts and legal structures of different countries. It can also cover some costs for CardanoWall public storage/redundancy + additional external servers used for creating screenshot/warc files described in the update above.

• Back-end: me, an additional senior JS developer, Cryptography/Cybersecurity specialist, independent security audit for BE and FE: 35000 USD
• Front-end: UX/UI improvements as new features appear, redesign: 2500 USD
• Infrastructure for 1 year (prod/dev/api servers, storage servers, crawlers for page PoE): 3000 USD
• Marketing: additional professional materials to onboard businesses, such as an explainer video I created. Online ads and social networks promotions: 17000 USD

The amount I am asking may seem high, but it's definitely not enough. That's why I also fund the project from the entire profit of my [VICE] stake pool that is producing blocks because of a high pledge I invested in it. By supporting my pool you support the further development of CardanoWall.

Mentoring

I would be happy to receive support and help from IOHK experts in the form of mentoring in cryptography, which takes a large and important part of the CardanoWall project.

Additional usage

CardanoWall offers much more than I could describe in a short problem statement/solution. You can effortlessly send messages to the Cardano blockchain network without needing to understand the technical goings-on behind the scenes. Your message will become part of the blockchain and will remain there forever. You can also include other types of information other than text, such as an image or geo-position, along with the text message. So it's a Twitter/Instagram built on a blockchain. Some artists already started using CardanoWall as an NFT platform to pass a private key that can decrypt the original artwork. Many new possibilities appear as the project develops with new features.

Roadmap:

Q3 2021: Public API for automatic creation of PoE records without the usage of CardanoWall website.

Q4 2021: An option to use individual wallets/addresses for businesses. Additional features for business accounts.

Q4 2021: Level 4 features for secure encrypted communication and transferring access to CW storage encrypted files.

Q3 2021 - Q1 2022: Building custom solutions for businesses and onboarding more companies for PoE usage on the Cardano blockchain.
