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	V1 • V2	V1 on Ethereum, V2 on Arbitrum
Curate	V1 • V2	Classic (V1), Light (V1), Stake Curate (V1 infra)
Escrow	V1 • V2	V2 adds settlement negotiation and multi-token support
Governor	V1 • V2	Optimistic execution on both versions
Scout	V1	Frontend reading from V1 Curate registries
Reality (Oracle)	V1	Kleros arbitration backstop for Reality.eth
Proof of Humanity	V1	See note below
Foresight	V2	Experimental prediction-market platform

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).
