Blockchain vs Sharepoint

Both are different as terms as replied by @Stefano Tempesta, But we have some thing which relates both:

Blockchain is now available for everyday document processing. Since the introduction of blockchain technology in SharePoint by Sphereon this week, the technology is now available for large-scale and daily usage of documents and transactions. The blockchain technology is used to guarantee the uniqueness and identity of objects, like documents, permanently. Microsoft SharePoint is widely used for large-scale information exchange and online collaboration within a group or organization.
