What is Eternum?

To know what Eternum is, first you need to know what IPFS is. Roughly, IPFS is a global, peer to peer network where you can host content and webpages. People who access content can then share it again, but that means that only content that exists on some node can be shared.

Eternum can make sure that content is always available on at least one node. Just pin an object, and Eternum will always keep it available to IPFS.

How do I pin things?

To pin an object, you need some balance in your account, and the hash of the thing. Then, just go to your account page and click "New pin". Enter the hash and (optionally) a friendly name to recognize the object by, and that's it.

The object needs to be available on the IPFS network, so if it's on a node you control, you should keep it online for a while, at least a few hours for content of a few megabytes and days for larger content. Eternum will try to pin the content for around a week, and if the content is never available during that time, it will give up and not bill you (it will show the size as 0).

If you start rehosting content that couldn't be pinned initially and want Eternum to retry, just remove the pin and add it again.

How much does it cost?

Pinning costs $0.00000000001 per byte per day, or roughly $0.30 per gigabyte per month, depending on the number of days in that month. You are billed per day for the amount of data you used for that day.

What are tags?

Tags are there to help you give a persistent URL to your changing content. Say you want to pin your site and give a URL to visitors so the URL stays the same, but points to a different IPFS hash every time. You can do that by setting a tag like "mysite", so now your site is always accessible at

When you update your site, you can just set the "mysite" tag on the latest version, and the tag will automatically be removed from the previous version and added to the latest one, so the tag will always point to the most up-to-date version of your site.

IPFS has a feature to do the same, called IPNS, but it is a bit fiddly and requires you to run your own daemon, so we provide tags as a convenience to you.

How can I make pinning faster?

If your content is on a node you control, you can make pinning much faster by connecting your node to ours. Just run the following command to connect to our IPFS node and help us discover your content directly (it's all on one line, just copy and paste it):

ipfs swarm connect /dns4/

How can I contact you?

What if I want to pin some illegal stuff?

Don't even think about it. We fully comply with the DMCA and other laws, and will turn you in if you try anything shady. Other than that, go nuts.
