Lido stated on social media that Lido DAO has launched an emergency proposal due to a suspected leak of Chorus One's oracle private key, intending to replace the single Lido oracle node it is responsible for.
Staking users are not affected, and the protocol remains secure and operational. Lido's oracle system uses a 5-out-of-9 multisig mechanism, so a single oracle failure does not threaten the system, and the other nodes remain unaffected.
