Tezos (XTZ) is a blockchain network linked to a digital token, which is called a tez or a tezzie. Smart Contracts and Dapps are included, the same as Ethereum, EOS, NEO blockchain network. Tezos is not based on the mining of tez. Instead, token holders receive a reward for taking part in the proof-of-stake consensus mechanism.
The system allows its blockchain to be continuously developed. By deciding the various powers will depend on the coin holder. Causing direction decisions to be made through all submissions and votes, which means that no Hard Forks will occur.
When any developer decides to develop the network, he could easily offer a petition then the Token holders will have to vote to agree or disagree with this upgrade. If there’s an agreement, that developer will receive a reward from Tezos's central account and the system will be upgraded aligning to the votes. This means that the network will be able to continuously develop indefinitely within the decentralized network.
Apart from that, Tezos is currently using the Delegated Proof-of-stake network which is similar to the proof-of-work network. The main difference is that there are no energy costs in order to mine the system physically, but virtually instead.
