Uploading to cloudflare IPFS enables computers all over the world to share and store files as part of a massive peer-to-peer network.

Let’s look at the details of uploading to Cloudflare IPFS.

Uploading to cloudflare IPFS

IPFS (Interplanetary File System) is a distributed file storage protocol that allows computers all over the world to store and serve files as part of a massive peer-to-peer network.If someone install IPFS on their computer and uploads a file to the IPFS network, that file may be read and downloaded by anybody else running IPFS across the world.

​​Content Identifiers

A hash of the file’s content is used to generate a unique address for each file added to IPFS. A Content Identifier(CID) is the name given to this address. It creates a single string from the file’s hash and a unique identifier for the hash algorithm used.

IPFS currently uses SHA-256 as its default algorithm, which produces a 256-bit (32-byte) output encoded with Base58. Base58 is a text-to-binary conversion scheme. It has the advantage of excluding letters that might be mistaken for one another in certain fonts.

A CID will usually look like this. 7sPxEY8HNuZAtCkcu8yaMeR5nW5hYhfsrTQqzTp9yTfV68Cm

Uploading to IPFS

IPFS is essentially a Distributed Hash Table (DHT) that maps CIDs to people who have access to the content addressed by that CID. Because no single node in the network owns the entire hash table, it is distributed. Instead, each node keeps a subset of the hash table as well as information about which nodes keep other relevant sections.

When someone says they’re ‘uploading’ content to IPFS, they’re announcing to the network that they have content by adding an entry to the DHT that maps their CID to their IP address.  Someone else could look up the CID in the DHT, find the person’s IP address, and download the data directly from them.

IPFS’s speed and reliability come from the fact that multiple people can upload the same data. And then downloads are distributed among them. If one of them goes down or decides to stop hosting the data, the others can step in to fill the void.

​​​​Directories

We have the ability to upload more than just individual files. For example, consider a folder called bobcares, which contains only one file, bobcares_text.txt, which contains the string we’re testing with IPFS. Both the folder and the file it contains would have their own CID if that folder was uploaded with the command ipfs add -r./example.

In this case, the folder’s CID would be 8TuE8wUEnACQUgtwb9a8YYK8Ztg3sUAxCBDAbY43nC8hGu, while the file’s would be uraJmy7QYhyc973dJbakCnmrumN8PduY5SPMzQKx2D53YF6q. The file could then be accessed in two ways:

• Directly requesting the file:

  https://cloudflare-ipfs.com/ipfs/uraJmy7QYhyc973dJbakCnmrumN8PduY5SPMzQKx2D53YF6q
• Requesting file from the directory by name:

  https://cloudflare-ipfs.com/ipfs/8TuE8wUEnACQUgtwb9a8YYK8Ztg3sUAxCBDAbY43nC8hGu/bobcares_text.txt

A file’s CID will change only if the file itself changes. A directory’s CID, on the other hand, changes whenever any of its files change or are added/removed. Directories allow us to address an entire static website with a single CID. We can  request different files in the directory to access different pages of the website.
