DNSChain

npm version Build Status Build Status Gitter

There is a problem with how the Internet works today:

  • HTTPS is not secure. Like most "secure" communications protocols, it is susceptible to undetectable public-key substitution MITM-attacks (example: Apple iMessages).
  • Netizens do not own their online identities. We either borrow them from companies like twitter, or rent then from organizations like ICANN.

These problems arise out of two core Internet protocols: DNS and X.509.

DNSChain offers a free and secure decentralized alternative while remaining backwards compatible with traditional DNS.

It compares favorably to the alternatives, and provides the following features: ︎

DNSChain X.509 PKI with Certificate Transparency
MITM-proof'ed Internet connections :white_check_mark: :x:
Secure and simple GPG key distribution :white_check_mark: :x:
MITM-proof RESTful API to blockchain :white_check_mark: :x:
Free and actually-secure SSL certificates :white_check_mark: :x:
Stops many denial-of-service attacks :white_check_mark: :x:
Certificate revocation that actually works :white_check_mark: :x:
DNS-based censorship circumvention :white_check_mark: :x:
Prevents domain theft ("seizures") :white_check_mark: :x:
Access blockchain domains like .bit, .p2p, .nxt, .eth :white_check_mark: :x:
Certificate transparency (publicly auditable log of certs) :white_check_mark: :white_check_mark: (maybe)
