One of the main things I love about altcoins is the fact we see many new and innovative features and platforms being created, which may be adopted by Bitcoin at some day in the future. As we are only beginning to understand the true power of the blockchain, one of the features I look forward to is file sharing/file storage. Opal seems to have a little something called Opal Drive up their sleeve, which brings that exact feature ever closer.
Most of you have probably never heard of Opal Drive before, and that’s OK, because you are here to be informed about what is going on in the world of digital currency. Sit back, relax, and I will try my best to explain everything to you.
File storage and file sharing are things we use on a nearly daily basis, without even thinking about it. Take this article for example, which is being written on my Chromebook, through the Google Drive application. Basically, I am writing this text in the cloud, where my content is not only created, but also stored.
Let’s say I have an article that is not completely finished, and I want to show it to one of our other contributors. I create a shareable link for this document, which in turn is file sharing through the cloud. As you can see, both are things we do without even thinking about it anymore.
The achilles heel of cloud file sharing and storage, which are both incredibly easy to use, is the security and encryption of files. A lot of different companies, who all have some of the world’s most brilliant minds among their employees, are working hard to find a solution to these inherent flaws.
So how does Opal fit into this picture, you wonder? The OPAL developers are creating an experimental system which allows individuals to upload,transfer and decrypt files by using the Opal Core wallet through the Storj MetaDisk API. (Click here for more information about MetaDisk)
Opal will build a transmission layer on top of the currently existing Storj MetaDisk infrastructure. The encryption of files will be made possible thanks to the encryption system to be found in Opacity. It actually goes one step further than that, as files can be encrypted with another user’s private key, when all you have is their public key.
Some of you might see the parallels between OPAL’s solution and PGP public key encryption, but there is a small difference. File transfers through the Opacity platform allow for encryption with the EDSCA, which is something PGP public key encryption does not allow.
Once your file is encrypted, it will be uploaded to Storj (which is a distributed file sharing network serving as OPAL’s off-chain secure method of file storage). A download link will be sent to the recipient through OpacityEM, and that recipient can then decrypt the downloaded file with their own private key.
Encrypting a file through both public and private keys may sound easy, but there is a lot more behind it than you might expect. I could try to explain it to you in detail, but you are better off reading the official Opal Drive whitepaper, which can be found here :
In closing, Opacity File Transfers are instant, decentralized and effortless, exactly the way cloud storage / file transfers should be. Furthermore, blockchain bloat is avoided entirely thanks to the use of the StorJ network. On top of that, Opacity’s encryption mechanism makes it impossible to figure out the file source or its recipient.
More information is expected to be released over the coming days and weeks, and we will keep an eye out for further updates
