# Blockchain

A public, purpose-built L1 for the OpenGPU Network.

## Why Our Own L1?

**Available now:**

* **High Throughput**: Standard EVM with parallel block validation (\~10,000 TPS)
* **Sub-second Finality**: Real-time task marketplace requires fast settlement
* **Focused Development**: Open, dedicated chain for protocol-specific updates and forks

**Future roadmap:**

* Consensus-level integration for task and provider management
* Private L1/L2 options for modular deployments

## Technical Specs

* **Consensus**: Lachesis DAG-based protocol
* **Block Time**: Sub 1 second
* **Throughput**: \~10,000 TPS
* **EVM Compatible**: Standard Ethereum tooling works out of the box
