About Cloud

Restaking Cloud is a restaking stack for Ethereum that lets validators and LST holders delegate into the K2 pool to earn extra yield, while protocols (“Borrowers”) rent ETH-backed security and Reporters enforce their rules on-chain. Payouts are designed to be in ETH, with Native Delegation so existing validators can participate without changing withdrawal credentials.

Quick Facts

  • Products: K2 (permissionless restaking pool) and Node Cloud (marketplace for ETH-secured node operations), plus SDK/docs for builders.

  • Participants: Restakers (ETH validators/LSTs), Borrowers (L1s, L2s, rollups, oracles, dApps), Reporters (execute/verify logic), Node Operators/PNOs.

  • Payouts: Designed for ETH payouts to Restakers/Reporters.

  • Compatibility: Promotes Native Delegation for the existing validator set; LSTs can participate as well.

  • Tokens: RSTs (Restaked Staking Tokens) are minted when Borrowers use K2, for protocol operations/accounting.

How It Works

  1. Restakers delegate ETH validator balance or LSTs into K2 (via Native Delegation or LST deposits).

  2. Borrowers (e.g., L2s/oracles) define slashing/liveness logic and borrow ETH-backed security through the K2 dApp.

  3. Reporters run/verify that logic and earn ETH for successful work; K2 routes payments.

  4. Node Cloud: Borrowers post requirements; PNOs opt in; Restakers direct liquid delegations of their K2 ETH toward operators securing specific networks.
