Summary

Lido implements an improvement of the OracleReportSanityChecker which aims to mitigate the riskof malicious oracle daemons colluding and reporting excessive negative rebases of stETH. “Lido is a liquid staking solution for ETH backed by industry-leading staking providers. Lido lets users stake their ETH – without locking assets or maintaining infrastructure – whilst participating in on-chain activities, e.g. lending. Lido attempts to solve the problems associated with initial ETH staking – illiquidity, immovability and accessibility – making staked ETH liquid and allowing for participation with any amount of ETH to improve security of the Ethereum network.
