EigenLayer has introduced an additional security feature for its EigenDA data availability service on the Ethereum mainnet to combat Sybil and distributed denial of service attacks. The new whitelist security measure employs either an internet protocol address or Ethereum's ECDSA authentication to ensure heightened protection and secure access. ECDSA authentication, a cryptographic method, verifies user, device, or system identity through public-key cryptography and elliptic curve cryptography. EigenLayer aims to safeguard its service while ensuring accessibility for all clients. EigenDA's free tier offers ample throughput, exceeding the needs of busy Ethereum rollups. Partners can request increased throughput beyond the free tier, fostering tailored solutions for diverse high-throughput applications. EigenDA achieves impressive peak throughputs on the mainnet and plans to introduce permissionless payments for blob throughput by 2024. EigenLayer's recent EIGEN token airdrop completion and staking opportunities further enhance its offerings on the Ethereum network. Read more AI-generated news on: https://app.chaingpt.org/news
