# DNSChain [](https://npmjs.org/package/dnschain) [)](https://travis-ci.org/okTurtles/dnschain) [)](https://travis-ci.org/okTurtles/dnschain) [](https://gitter.im/okTurtles/dnschain) There is a problem with how the Internet works today: - HTTPS [is not secure](http://okturtles.com/#not-secure). Like most "secure" communications protocols, it is susceptible to undetectable public-key substitution MITM-attacks (example: [Apple iMessages](https://www.taoeffect.com/blog/2014/11/update-on-imessages-security/)). - 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](https://en.wikipedia.org/wiki/Domain_Name_System) and [X.509](https://en.wikipedia.org/wiki/X.509). DNSChain offers a free and secure decentralized alternative while remaining backwards compatible with traditional DNS. It compares favorably to [the alternatives](docs/Comparison.md), and provides the following features: | | DNSChain | X.509 PKI with [Certificate Transparency][ct] | |:-------------------------------------------------------------------------|:-------------------|:----------------------------------------------| | __MITM-proof'ed [Internet connections][mitm]__ | :white_check_mark: | :x: | | __Secure and simple [GPG key distribution][gpg]__ | :white_check_mark: | :x: | | __MITM-proof RESTful [API to blockchain][api]__ | :white_check_mark: | :x: | | __Free and [actually-secure][free] SSL certificates__ | :white_check_mark: | :x: | | __Stops many [denial-of-service attacks][dos]__ | :white_check_mark: | :x: | | __Certificate revocation [that actually works][rev]__ | :white_check_mark: | :x: | | __DNS-based [censorship circumvention][cens]__ | :white_check_mark: | :x: | | __Prevents [domain theft][theft] ("seizures")__ | :white_check_mark: | :x: | | __Access blockchain [domains like `.bit`, `.p2p`, `.nxt`, `.eth`][use]__ | :white_check_mark: | :x: | | __Certificate transparency (publicly auditable log of certs)__ | :white_check_mark: | :white_check_mark: ([maybe][ct]) | [ct]: https://blog.okturtles.com/2015/03/certificate-transparency-on-blockchains/ [mitm]: docs/What-is-it.md#MITMProof [gpg]: docs/What-is-it.md#GPG [free]: docs/What-is-it.md#Free [dos]: docs/What-is-it.md#DDoS [rev]: docs/What-is-it.md#Revocation [cens]: docs/What-is-it.md#Censorship [theft]: https://www.techdirt.com/articles/20141006/02561228743/5000-domains-seized-based-sealed-court-filing-confused-domain-owners-have-no-idea-why.shtml [use]: docs/How-do-I-use-it.md [api]: docs/What-is-it.md#API **:star: See Also: [Comparison](docs/Comparison.md) and [Security Model](docs/Security-Model.md)** **:star: April 21, 2017: Comparison of [DPKI](https://github.com/okTurtles/dnschain/issues/180#issuecomment-255***13***) to [CONIKS, Key Transparency, Certificate Transparency](https://blog.okturtles.com/2017/02/coniks-vs-key-transparency-vs-certificate-transparency-vs-blockchains/)** ## Documentation ### [:book: What is it?](docs/What-is-it.md) - DNSChain replaces X.509 PKI with the blockchain - MITM-proof authentication - Simple and secure GPG key distribution - Secure, MITM-proof RESTful API to blockchains - Free SSL certificates become possible - Prevents DDoS attacks - Certificate revocation that actually works - DNS-based censorship circumvention - Other features: testing suite, rate-limiting, and caching ### [:book: Using DNSChain](docs/How-do-I-use-it.md) - Free public DNSChain servers - Access blockchain domains like `okturtles.bit` - Registering blockchain domains and identities - Encrypt communications end-to-end without relying on untrustworthy third-parties - Unblock censored websites *(coming soon!)* - And more!
