Here's a list of DNSCurve servers, tools, and other software. DNSCurve is a fully backwards-compatable extension to DNS that adds link-level authenticated encryption. Most implementations use NaCl, libsodium, or slownacl for cryptographic operations.
Please also see DNSCurve.io for more DNSCurve information.

- Dan Bernstein: "An attacker who spends a billion dollars on special-purpose chips to attack Curve25519, using the best attacks available today, has about 1 chance in 1000000000000000000000000000 of breaking Curve25519 after a year of computation."
- Ian Grigg: "In the past, things like TLS, PGP, IPSec and others encouraged you to slice and dice the various algorithms as a sort of alphabet soup mix. Disaster. What we got for that favour was code bloat, insecurity at the edges, continual arguments as to what is good & bad, focus on numbers & acronyms, distraction from user security, entire projects that rate your skills in cryptoscrabble, committeeitus, upgrade nightmares, pontification ... Cryptoplumbing shouldn't be like eating spagetti soup with a toothpick. There should be One Cipher Suite and that should do for everyone, everytime. There should be no way for users to stuff things up by tweaking a dial they read about in some slashdot tweakabit article while on the train to work... Picking curve25519xsalsa20poly1305 is good enough for that One True CipherSuite motive alone... It's an innovation! Adopt it."
