Hi everyone ✌️, Walterion from BlackHole team is here, and I’m super excited to introduce you to BlackHole 1.0 ✨, a platform for fast and private file transfer that works over blockchain technology. As we keep hearing about data breach news of big companies like Dropbox or WhatsApp, it is harder for us to keep trusting them with our file and personal data, and it made us think about finding a better way. We think the best way to keep data secure is not having them in the first place. That’s why we choose the server-less solution, in other word, blockchain. The most challenging part for us was designing a blockchain app that doesn't look like a blockchain app! We wanted to make the transition from centralized to decentralized solution as smoothly as possible. That is where Blockstack comes in to help us with a secure and decentralized authentication service, working on Bitcoin blockchain. BlackHole is a fully native app – no clunky Node.js –; as a result, it has so much less system usage (10MB of ram!) and great user experience. Being native also provides multiple layers of encryption with excellent performance. BlackHole lives in your menu bar and lets you send files with only one click. Your shared file split into parts, encrypt, and then upload to a random hub of your choice. It gives you a private share link that plays the role of a key. No one can access the file without this link. Unlike traditional centralized services, BlackHole doesn't know about who, whom, what, and where the file shared! That’s the reason we name it BlackHole 🕳 🤓 Here is where BlackHole shines: 🔑 Secure as Crypto Money. Blockchain ,plus industry-standard AES CBC with 256 bits key ,plus PKCS7 padding pattern. 📤 Data streaming. No need to waste time on uploading progress, links are generated and shareable instantly, and receiver can also see how uploading goes! 🍬 Designed for everyday use. Press Command/Ctrl + B on any file or folder, you now have a private share link in your clipboard. Hold the Shift key while doing this, and add your defined password as extra protection. If you are a mouse guy, you can drag-n-drop one or more files at the same time into the BlackHole tray icon as an alternative way. 🗜 Transfer compression. With the smart compressor along with multipart upload, it can save up to 90% of transfer time. BlackHole is available for Windows and Mac, and more is on the way. Also, to hold our security claim, we released the source as open to anyone. Take a look at it in GitHub link. We can’t wait to hear what you think. Please do not hesitate to ask me any question. “Share a file and keep your privacy. BlackHole.”

@walterion1 this is amazing :) well done :) IPFS or swarm is it? how do you handle the traffic? built with electron?
Walterion

@ucefkh Thank you very much Youssef. Neither one, Blockstack and Bitcoin + Many layers of encryption. We made it with Pascal language and it is a native app. But we have a web client too that is written in JS. Let me know if you have more questions and don't forget to spread the love ;)
blockstack yummy
I just tried your app , even feel faster than dropbox and google drive. But , your source codes use pascal, really hard to check malicious codes inside or not.
Walterion
Maker
@blockstack_yummy Happy to hear that. We chose Pascal because it lets us to compile BlackHole for multi-platforms with excellent performance. P.S. Actually Pascal is famous for being easy to read! 😁
blockstack yummy
really fast, good jobs. Do you have more guides on how to test the source codes on local pc? Your github guides don't have more details about how to compile it. @walterion1

@blockstack_yummy Thank you very much. The project is just started, we will improve the doc along the way. Please watch the repo on Github for updates.

I just saw this on my producthunt feed, I liked the logo and the title of the idea, I entered to see what was going on, I visited the website, downloaded the app, I installed the app, I completed the 3 steps (15 secs) tutorial and shared my first file. This is really simple and easy to use for the user. Keep it great!

Pros:

Fast, Easy to use, Clean.

Cons:

Too perfect to be real.

Even in theory, decentralization storage is fantastic! The effort these guys put into polishing this app is incredible. 👏🏽

Pros:

It's actually faster than Dropbox! Have a handy interface and distributed storage.

Cons:

Lack of Linux version

Happy to here that 😁. Actually Linux version is on the way 👨‍💻

seems handy

@selinayinsesi We designed it to be handy for everyday use. 👍 You can just use Ctrl+B (or Command+B on Mac) shortcut on any file.
Vlad Korobov
Please, correct me if I'm wrong. I rely on the network to store blocks of my files. The only difference between classic p2p is security?
Sienna Hayez
Maker
@vladkorobov The difference is privacy + security guaranteed by first multi layer encryption in client and server side, and a password protection layer as an extra option, then user data ownership with the help of BlockStack Gaia hub private for each user, in another word, when users own their key, they own their data, then neither BlackHole nor BlockStack are able to access user data without that key. But if you mean when an upload is going on, how the download process can be proceed? then BlackHole has a cool feature in which, you can start downloading as soon as upload begins, no need to wait for upload to be completed. But in the end of upload process, the shareable link will be available for download forever, no need for the sender to be online, because the encrypted data is stored in Gaia hub.

Product seems like a great tool - can't wait to use. As someone with Keratoconus though, the graphics you use on the site (vector images with the blur behind it) make it impossible to read, I couldn't focus on anything and had to close the tab. I'm not asking you to change it, just thought you should know. Anyone with double-vision or astigmatisms will probably have an issue reading it too.

Do you plan to release a version for Linux?
Walterion

How exactly is blockchain involved?
Walterion
Maker
@friedger_muffke BlackHole uses Blockstack DNS that built on top of the Bitcoin blockchain, to address users hubs that provide access to the encrypted and private storage.
Sharman Linkoz

Love the whole idea. Keep it up!

Pros:

No client needed on the download side. Good for active collaboration. No need to organize files before sending. Generous free plan.

Cons:

Nothing

It's really awesome. But I can't find how I can delete my shared file, is it possible?

@omar_antila @walterion1 Hi Walterian Shareable link of old files is disabled in my app. Only 3 files are enabled at a time. why? .It says there is no expiration date but why limited number of files?.
Ousmane NDIAYE
Nice concept, I really do love the ability to start a download before the upload has complete !
Walterion

@ousmane_ndiaye Thank you very much Ousmane. It uses internal compression too, so it works fast!
