With the incorporation of this security measure, EigenLayer seeks to protect the service it offers while guaranteeing its availability to all clients.
EigenLayer has implemented an additional security feature for its EigenDA data-availability service on the Ethereum mainnet to prevent Sybil and DDoS attacks.
According to the EigenDA’s X post announcement, this whitelist security measure utilizes either an IP address or Ethereum address Elliptic Curve Digital Signature Algorithm (ECDSA) authentication to ensure enhanced protection and secure access to the service.
ECDSA authentication is a cryptographic method for verifying the identity of a user, device, or system. It is based on the principles of public-key cryptography and uses elliptic curve cryptography to ensure secure authentication.
