# Providers and Services

The **Züs Subsystems** consist of various providers and services that ensure the **decentralization, security, and efficiency** of the network. 

This section details the key providers responsible for blockchain operations and storage, along with helper subsystems that support the network infrastructure.

### **Core Subsystems Providers**

These are the fundamental providers that play a role in maintaining the blockchain and storage infrastructure:

* **Miner :** Miners are responsible for **maintaining the blockchain** and implementing the **consensus protocol**.
* **Sharder:** Sharders are responsible for **persisting blockchain data** and providing network insights through APIs.
* **Blobber :** Blobbers are the **primary storage providers** in the Züs network.
* **Validator:** Validators play a key role in **verifying Blobber storage claims**.
* **Authorizer:** The **Authorizer** facilitates the **ZCN↔WZCN Bridge Protocol**.

### Helper Subsystems Providers/Services

These additional services support network functionality and integration:

* **Node Locator (0DNS):** 0DNS helps external services and clients discover active network nodes.
