Perpera plugin for Nextcloud

Perpera is coming to Nextcloud.

The primary purpose of this protocol is to record cryptographic hashes of successive revisions of single-file documents in a public blockchain, in a manner which enables clients to easily query and verify document histories. Such histories inherit useful properties from the underlying blockchain, namely immutability and massive replication, and can therefore serve as proofs of existence.

After implementing the web app, the next goal is to approach the potential users via Nextcloud plugin as well.

Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud application functionally is similar to Dropbox. Unlike Dropbox, Nextcloud does not offer off-premises file storage hosting. Nextcloud is free and open-source, which means that anyone is allowed to install and operate it on their own private server devices.

Please test it and provide feedback. We are especially interested in adjusting the workflow to be as comfortable as possible from a user interface standpoint. Knowing that key management is likely the hardest task to handle by a common blockchain user, we shall strive to implement Ledger Nano and Trezor T support Perpera. Users will not have to worry about keys and notarize their documents from the safety of the hardware wallet.
