walytis-offchain 0.4.0

An overlay for the Walytis blockchain that stores block content off-chain and securely shares it only with trusted peers, using `walytis_identities`.

Walytis Offchain Storage

P2P encrypted and authenticated communications, based on WalytisIdentities.

Features

• fully peer-to-peer: no servers of any kind involved
• encrypt and send messages to all peers controlling a specified Walytis Identity
• decrypt and authenticate received messages, validate authorship by a Walytis Identity
• offchain storage: encrypted messages are not stored as Walytis blocks or IPFS content for security
  • a full record of past message metadata is always kept (guaranteed by the Walytis blockchain), message content can be deleted and forgotten if all peers decide to do so.
• identity management features inherited from Walytis Identities:
  • multi-controller support: a Walytis Identity can be managed by any number of controllers
  • identity nesting: Walytis Identities can be controlled by other Walytis Identities
  • ephemeral cryptography: regular key renewal, algorithm-agnostic, room for future algorithms

Documentation

The thorough documentation for this project and the technologies it's based on live in a dedicated repository:

• WalytisOffchain: learn how WalytisOffchain works
• Walytis Technologies: learn about the suite of tools which WalytisOffchain is part of, built to enable developers to easily develop peer-to-peer distributed applications.

Project Status EXPERIMENTAL

This library is very early in its development.

The API of this library IS LIKELY TO CHANGE in the near future!
