Babylon Protocol vs Spark

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.

SparkLend is MakerDAO’s permissionless lending front‑end that pipes DAI liquidity directly from the Maker core vault into isolated lending markets. Because the backend uses D3M credit lines, borrowers enjoy below‑market rates that float with the DAI Savings Rate. Since launch on Ethereum mainnet in May 2023 Spark TVL has oscillated between 300‑600 million DAI and is governed by MKR Executive Votes.
