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.
In the registry that makes up Blockstack, each of the names has an owner, represented by a cryptographic keypair, and is associated with instructions for how DNS resolvers and other software should resolve the name.
Blockstack is already being used in production and currently more than 46,000 names have been registered using it.
Run the following to install the Blockstack command line interface:
$ sudo pip install blockstack
Below are some repositories and tools that are needed to register, resolve, and authenticate names in a decentralized way:
- Blockstack Server - the server that handles the core functionality of the decentralized domain name system and has an external storage system built-in for storing data records off-chain
- Blockstack Client - a CLI and client library that provides an interface for interacting with Blockstack servers and performing decentralized DNS operations
- Virtualchain - a Python library for creating virtual blockchains on top of any underlying blockchain
- Blockstack Resolvers - scalable servers for resolving names to data records at scale
- Blockstack Registrars - servers that can do bulk Blockstack name registrations and updates
- Blockstack DHT Mirrors - software that improves read and write performance for the Blockstore DHT
- Blockstack Auth JS and Blockstack Auth JS - libraries that support generating, decoding and verifying auth request and auth response tokens
Most of these repositories are under heavy development and we appreciate any feedback, bug reports, or code contributions!
