+cat GIF, but you'd need to use a different API for that.)

+You can create a new node by passing a data object into the `ipfs.dag.put` method,

+
+A CID is an address for a block of data in IPFS that is derived from its content. Every
+time someone puts the same `{hello: 'world'}` data into IPFS, they'll get back an
+identical CID to the one you got. If they put in `{hell0: 'w0rld'}` instead, the
+CID will be different.
+
+_Note: Throughout our lessons we'll be using a code editor like the one below.
+Enter your solution code within the `run` function that's pre-populated for you,
+being sure to return the requested value within that function. (You won't need to
+update the `return run` line at the end; that's just there to make the code editor work.)_

+The `prev` field contains a link to the previous blog post. You can use that CID and the `ipfs.dag.get()` API to get the previous blog, and then use _its_ `prev` field to get the one before that. A perfect use case for a while loop!
 
-Note: the `ipfs.dag.get()` API returns an object with a `value` attribute which is the node you want. Also, **links will be binary encoded**, so if you want them to be CID instances you'll need to use the `cid` module.
+Note that the `ipfs.dag.get()` API returns an object with a `value` attribute which is the node you want and contains the original fields you saved. For example, we could find the author of the post about dogs like so:
 
 ```javascript
-let cid = new CID((await ipfs.dag.get(someCid)).value.linkName['/'])
+let dogPostAuthor = (await ipfs.dag.get(dogPostCid)).value.author
 ```
 
-This kind of traversal could be used to create an overview page that lists all blog posts.
+Notice the parentheses used around `await ipfs.dag.get(dogPostCid)` above, since the async function needs to complete before the CID object with a property of `value` will be available. When you're using this code in practice, it's important not to make too many async calls that will create lag time.
