Nonchalantly Performs Magic

    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
    Secure and simple GPG key distribution
    MITM-proof RESTful API to blockchain
    Free and actually-secure SSL certificates
    Stops many denial-of-service attacks
    Certificate revocation that actually works
    DNS-based censorship circumvention
    Prevents domain theft ("seizures")
    Access blockchain domains like .bit, .p2p, .nxt, .eth
    Certificate transparency (publicly auditable log of certs) ✅ (maybe)
