[Ndn-interest] Understanding Named Data Networking

[Varun Patil]

Hi Ender,

A key difference is IPFS CIDs are just hashes of the content, they are
not meaningful in themselves. In NDN, each data object is
*semantically* named. Importantly, the data names are used for
security - to establish trust relations between data and data
producers using well-defined naming rules.

This makes it possible to build real applications over NDN (unlike
IPFS, which is just a storage layer). But even If you're looking only
at content delivery, the design is very different from IPFS.

The NDN 101 page is still a work in progress, but is useful as a
tutorial - https://101.named-data.net/

Most of the details can be found over the many papers written over the
years. The 101 page has some pointers to these but other people here
could have specific suggestions.

Best,
Varun

From an initial impression, the content delivery strategy of the protocol reminds me of IPFS CIDs. Is this over-simplified understanding of Named Data Networking accurate whatsoever?
