There are solutions such as Wetransfer or smash that allow us to send large files over the Internet, up to 2 gigabytes in size in the free option, more than enough for most needs.
The problem appears when we want to send files of several Gigs, or even folders of several Teras, and we do not want to spend a huge amount of money on platforms like Dropbox or Google Drive.
This is where Saturn appears, a new unlimited solution that does not use a server, uses P2P technology so that the shipment is made between connected computers.
Users can upload multiple files, and the recipient will download a zip with all the content inside.
The solution runs on a blockchain where everything is public. They do not encrypt the files we are uploading, so uploading anything that is confidential is not recommended.
They also offer the possibility of signing a file if we connect our wallet. This is a good way to authenticate the provenance of a file and thus avoid “I didn’t send it” problems.
Once the files are submitted, we can get a unique link that we will share with other people. Anyone with the link can download the content.
It is also possible to lock files for specific users. In these cases, when the link is shared, the recipient will need to log into their wallet, which is linked to an IDX account. That means you can share this with anyone who has wallets on any blockchain.
