In Pubky, your public key is your self-sovereign domain name. This is accomplished with Public Key Addressable Resource Records (PKARR) acting DNS records that you control within Mainline DHT nodes.

People like to cast a lot of doubt on DHTs as a solution for decentralization, but we have been asserting that this method is best because Mainline DHT consists of 'bajillions' of nodes and is 'literally' the most decentralized and censorship-resistant network on the internet.

Are these exaggerations?

Below, Ar Nazeh, from the Pubky team at Synonym, provides some reproducible research you might appreciate.

If you want to read about Mainline DHT censorship resistance to Sybil attacks we wrote something here: https://github.com/pubky/mainline/blob/dev/docs/censorship-resistance.md

If you want to verify the DHT size yourself, run this script and read about the methodology here: https://github.com/pubky/mainline/blob/dev/docs/dht_size_estimate.md#see-it-yourself

TLDR?

Mainline DHT is huge, extremely fast, rock-solid reliable, and hasn't gotten any smaller.
