Nextcloud introduces blockchain-based cloud storage

Open source cloud provider Nextcloud has introduced blockchain-based cloud storage using technology known as Sia.

The company likened it to Bitcoin for data, providing encrypted, distributed and affordable storage.

Sia has developed a Nextcloud external storage app providing its redundant and secure data store to Nextcloud users.

Nextcloud has released a guide for using Sia along with a Nextcloud instance.

The main reason for using Sia is because existing cloud storage providers are centralised.

"Costs are high, data is often unencrypted, and each provider typically runs only several large data centres. Sia, by contrast, allows for private, decentralised, distributed cloud storage at a far lower price," the developers say

Nextcloud Community spokesman Jos Poortvliet told iTWire that the Sia integration provided a way to expand their storage through an encrypted, distributed, redundant and global storage technology.

"Sia is fully open source and its blockchain foundations provide an impressive cost saving compared to Amazon, Google and other public clouds," he said.

Nextcloud was formed by forking from a company known as ownCloud last June.
