Blockstack - Decentralized DNS for Blockchain Applications

Blockstack is decentralized DNS and identity. With the Blockstack software, a network of computers collectively maintain a global registry of names. When you run a Blockstack node, you join this network, which is more secure by design than traditional DNS systems and identity systems. This is because the system's registry and its records are secured by an underlying blockchain, which is extremely resilient against tampering and control.
