Three weeks ago we announced a new protocol called Bitcoin Files Protocol (BFP) and the initial implementation using the Electron Cash SLP wallet. We also announced a simple roadmap for BFP which included a website for uploading/downloading files and also a JavaScript SDK.
We're happy to say that both of these items have been completed today, and now we have a more ambitious roadmap for BitcoinFiles.com which we hope to announce in the coming weeks.
Uploading Files.
Uploading and sharing small files to the Bitcoin Cash blockchain is now extremely easy using the BitcoinFiles.com web interface. The website provides a simple to use UI for uploading and downloading files directly to/from the blockchain, with MoneyButton integration as well as traditional QR code support. Uploads payment support for the BadgerWallet is coming soon.
Simply go to BitcoinFiles.com, click Upload a File and pay the mining fee and a small developer convenience fee (currently $0.25). You can then copy the file's URI for that file and share it with anyone.
File URI is provided after the upload is complete:
Downloading Files
To download files, click Download a File and paste in the file URI to download. Your browser will begin downloading the file to your device.
Exploring Files
Exploring what files already exist on the Bitcoin Cash blockchain is easy by clicking "File Explorer", which will redirect the user to a special bitquery on BitDB.network.
Finally, I want to direct you to the JavaScript SDK for BFP on GitHub. This SDK was built using BITBOX and BitDB and makes uploading and downloading files to the blockchain extremely from any JavaScript application. The README file provides code examples and shows how to store small files on Bitcoin Cash using BFP and JavaScript.
