Share your thoughts without any censorship using the power of encryption and get paid for it.
The problem Blyptor solves
Currently there is no mechanism for a blogger to publish sensitive material without it being censored by the platform where the blog is published. Also, if a blogger publishes his/her blog on a famous platform like Medium then there is no robust way for him/her to allow people to read the blog after paying for it.
Our app, Blyptor, is a chrome extension to solve both of these issues using the power of blockchain!
We're using NuCypher to encrypt a blog. After a reader pays for an encrypted blog to the blogger, the encrypted blog data is rekeyed to reader's key using proxy re-encryption.
Challenges we ran into
There is a limitation in NuCypher which was a significant hurdle for us. After a blog reader gets access to an encrypted blog and decrypts it to read it, he/she loses the access. So, the access needs to be granted again to the reader for him/her to read the blog again. We got around this problem by local caching the blog data once it is decrypted.
