#DeFi快讯# Launched in June 2024, Symbiotic, a new type of re-staking protocol, has become the second largest re-staking protocol after EigenLayer. With its shared security protocol, Symbiotic allows networks to customize their staking processes, collateral types, node operator selection, rewards, and slashing mechanisms, while maintaining security through non-upgradeable core contracts on Ethereum. Unlike the ETH-centric EigenLayer, Symbiotic offers a wide range of staking options for greater flexibility. Symbiotic's five pillars include collateral, vaults, operators, resolvers, and networks. Symbiotic's modular design and support for ERC-20 collateral challenges the existing re-staking paradigm and opens up new avenues for innovation and flexibility.
