# Planck₁

**Planck₁: The Compute Chain**

Planck₁ is Planck's sovereign Layer-1 blockchain, purpose-built to power decentralized compute at the protocol level. While Planck₀ serves as the coordination and modular base layer for launching sovereign AI chains and DePINs, Planck₁ acts as the execution engine—embedding GPU access, model orchestration, and real-world utility directly into the chain itself.

Planck₁ integrates:

* **On-Chain Compute Primitives**\
  Smart contracts with native access to GPU scheduling, inference jobs, compute payments, and fine-tuning triggers.
* **Decentralized GPU Economy**\
  Node operators earn rewards by providing GPU compute via Planck₁’s embedded marketplace, with programmable staking and reputation systems.
* **Vertical-Specific Compute L1s**\
  Industries such as healthcare, defense, robotics, and fintech can build their own compute-rich L1s on top of Planck₀ and settle workloads through Planck₁.
* **Bring or Rent Hardware**\
  Builders can onboard their own GPUs into Planck₁ or rent compute via Planck GPU Console and AI Studio—all with tokenized economics and native access.

**Why Planck₁ Matters**

Planck₁ turns AI infrastructure into a programmable, on-chain service layer. It does what centralized clouds cannot: offer public, permissionless access to state-of-the-art GPUs (H100s, B200s, etc.) while aligning incentives through Web3-native economics. It is uniquely designed to support:

* Real-time inference and model hosting
* Open-source model marketplaces
* Research-focused fine-tuning environments
* Low-latency, high-throughput GPU coordination

Whether used directly or as a base for vertical L1s (like BioAI chains or defense networks), Planck₁ serves as the decentralized GPU-powered backbone of the Planck ecosystem.
