Babylon Protocol vs ether.fi Stake

Babylon exports Bitcoin’s economic security to Proof‑of‑Stake networks by letting holders restake native BTC without wrapping. Validators lock BTC in time‑locked UTXOs; mis‑behaviour is punished via cryptographic slashing that burns the locked coins. A Cosmos‑SDK based testnet secured by Babylon went live in March 2024, paving the way for mainnet in late 2025 and integrations with EigenLayer and Berachain.

Ether.fi offers non‑custodial liquid staking where users mint eETH while retaining full control of validator withdrawal credentials via a smart‑contract escrow. Validators are run by a professional operator marketplace, and any user can migrate their keys or exit to the beacon chain 1:1. Launched in March 2023, ether.fi holds over 800 k ETH and shares validator bribe rewards with stakers through the ETHfi governance token.
