Palladium is an IPFS pinning service designed to make sharing data of any size secure and easy.
How does Palladium work?
Palladium uses XChaCha20-Poly1305, or AES256-GCM - the same encryption ciphers found in TLS 1.3 to encrypt data. Palladium also works very similarly to TLS 1.3 in the way it encrypts the data. The data is split into small chunks, which are encrypted using a combination of the previous block's verification tag and the sequence number. Almost like a blockchain. The encrypted file is then added to the IPFS network and can optionally be pinned, at which point Palladium will download the blocks and store them permanently.
There will be a whitepaper explaining how the protocol works, and why certain decsions have been made in regard to cipher choices, KDFs, block sizes, etc.
When will Palladium be available?
The project is currently under development - there should be a beta out sometime late March or early April.
