# Network Design

Tetreum uses a permissioned validator set to support security and performance.

Blocks are described as being produced at predefined intervals by a rotating set of trusted signers, with the goal of enabling fast finality and minimizing forks.

## Network capabilities

* **EVM execution:** Solidity-compatible smart contracts
* **RPC access:** Public interfaces for apps and tooling
* **Gas efficiency:** Low-cost execution for users and developers
* **Upgradeability:** Modular protocol evolution without disruptive hard forks

The architecture is designed to support fast synchronization and predictable behavior across nodes.
