Proposal to use blockchain technology to decentralise the DNS and make it more secure
Blockstack (a provider of blockchain infrastructure) is proposing the use of blockchain technology to decentralize the Domain Name System (DNS) and make it more secure. According to the proposal, the Bitcoin blockchain would be used to register and cryptographically protect domain names by using distributed ledger technology. DNS root servers would be replaced with a blockchain for storing information on registered domain names. This is expected to make the DNS more secure (as there would be no central points of trust or failure), to facilitate the administration of domain names by the registrants, and to make obsolete any censorship attempts (as domain names could not be seized from owners without getting access to their private keys). More details here and here.
