Babylon Protocol vs Lido

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.

Lido is the largest liquid‑staking protocol, minting stETH and other LSTs that track underlying validator balances 1:1 minus a 10 % reward fee. Its dual‑dao governance splits responsibility between the Lido DAO and the protocol’s Node Operator Registry, reducing centralisation risk. By May 2025 over 9 million ETH—roughly 30 % of staked supply—was custodied under Lido smart contracts.
