What's Tezos?

Institutional Grade Security.

Tezos is designed to provide the safety and code correctness required for assets and other high value use cases at both the protocol and application layers by leveraging languages OCaml and Michelson, which facilitate formal verification, a practice commonly used in mission-critical industries, spanning from nuclear and aerospace to semiconductor and others.

Governance by the People.

The Tezos platform was built with mechanisms to ensure active community governance and participation. Users can actively participate by evaluating, proposing, or approving amendments to Tezos. This design empowers the type of collaborative innovation that keeps Tezos on the bleeding edge of technology.

An Energy-Efficient Algorithm.

Unlike Proof-of-Work blockchains like Bitcoin or Ethereum, Tezos’ Proof-of-Stake requires significantly less energy and cost to operate, making it an ideal alternative platform for building blockchain applications that are eco-friendly.

Smarter Smart Contracts.

Tezos is one of the leading smart contracts Proof of Stake blockchains. Tezos smart contracts can use formal verification, allowing them to be mathematically verified, reliable, and secure.

Seamlessly, Forklessly, Endlessly Upgradeable.

Tezos is built to adjust, adapt, and add features and functionality through its proven on-chain upgrade mechanism.

Powerfully Scalable.

Tezos is built to remain state-of-the-art. Its modular architecture and formal upgrade mechanism minimizes disruptions while offering regular upgradability and enhanced functionality over time.
