Blockstack aims to create a decentralized Internet (Web 3.0), the core of which is responsible for security is the Bitcoin network. Blockstack uses a new Proof of Transfer POX consensus algorithm that allows the use of a highly secured Bitcoin network to create blocks in new blockchain such as Stacks. Miners wishing to secure the new network can spend their Bitcoins, which will participate in the creation of new blocks in Stacks blockchain. In return, they will receive STX coins. Also STX holders, called Stackers, can lock up their STX for a number of reward cycles, and in doing so receive Bitcoin.
