This technology didn’t just pop up overnight! In this section we’ll cover the background of decentralized storage from torrents until now, and go through some basics terminology to get you up to speed.
Using IPFS in the Browser
Visit try-ipfs.theblockchaininstitute.org to explore IPFS from your browser. No download required!
Using the IPFS Command Line
In this module, we cover how to set up your own IPFS node, and how to push and pull files from the network. We’ll also go over the addressing structure and get you caught up on the background of this technology.
State of the Industry
IPFS is just the beginning - in this module we'll catch you up on the developments currently affecting the space, and cover the various cryptocurrencies and tokens that have proposed incentive models for peer to peer storage.
The IPFS web portal makes uploading and sharing files using IPFS easy. As a demonstration, we’ll store this photo of Alex’s dog on IPFS and share it with ourselves.
Here’s the image:
You can now click and drag files onto the drop box on the right to upload them to your node. Once uploaded, you’ll see them added to the list as shown below.
You can also send a link to this page to allow others to easily download the same file. Just click the ‘Link’ button on the right once your upload is complete. The IPFS address of this file is:
QmT6s9dZXRFbxGhvSW68BdZEFF9mHaTW6erH3TNMrRGZfX so if you’d like to download it through the web interface, you could do so at https://try-ipfs.theblockchaininstitute.org/?q=QmT6s9dZXRFbxGhvSW68BdZEFF9mHaTW6erH3TNMrRGZfX.
As we’ll explore more in the following section, IPFS addresses are file-specific, not owner specific. The address is actually a unique key for the file that you uploaded. It’s derived by taking the hash of the file, which means that it can also act as a checksum. If anyone tries to send you another file in its place, your node will reject the imposter when it’s hash does not match that which was requested.
