## Protocol Version Guide

Kleros products run on two protocol versions. **V1** is the production-proven protocol on Ethereum L1; **V2** is the next-generation upgrade on Arbitrum L2. The table below shows where each product stands today.

| Product                                          | Available on | Notes                                                  |
| ------------------------------------------------ | ------------ | ------------------------------------------------------ |
| [Court](/court/overview)                         | V1 • V2      | V1 on Ethereum, V2 on Arbitrum                         |
| [Curate](/products/curate)                       | V1 • V2      | Classic (V1), Light (V1), Stake Curate (V1 infra)      |
| [Escrow](/products/escrow)                       | V1 • V2      | V2 adds settlement negotiation and multi-token support |
| [Governor](/products/governor)                   | V1 • V2      | Optimistic execution on both versions                  |
| [Scout](/products/scout)                         | V1           | Frontend reading from V1 Curate registries             |
| [Reality (Oracle)](/products/reality)            | V1           | Kleros arbitration backstop for Reality.eth            |
| [Proof of Humanity](/products/proof-of-humanity) | V1           | See note below                                         |
| [Foresight](/products/foresight)                 | V2           | Experimental prediction-market platform                |

<Warning>
  **Proof of Humanity note:** PoH has its own "V2" product upgrade (cross-chain support, improved UX), but it still uses the **Kleros V1 protocol** for dispute resolution. Don't confuse "PoH 2.0" (the product) with "Kleros V2" (the protocol).
</Warning>
