EigenLayer Enhances Security for EigenDA Service on Ethereum Mainnet to Prevent Attacks

EigenLayer has added a new security feature to its EigenDA data availability service on the Ethereum mainnet to combat Sybil and distributed denial of service attacks. In an announcement from EigenDA, the whitelist security measure is described as using either an internet protocol address or Ethereum’s elliptic curve digital signature algorithm (ECDSA) authentication for enhanced protection and secure service access. ECDSA authentication is a cryptographic method that verifies the identity of a user, device, or system. It relies on public-key cryptography and employs elliptic curve cryptography for secure authentication. With this additional security measure, EigenLayer aims to safeguard its service
