EigenLayer has implemented an additional security feature for its EigenDA data availability service on the Ethereum mainnet to prevent Sybil and distributed denial of service attacks. The whitelist security measure utilizes either an internet protocol address or Ethereum's elliptic curve digital signature algorithm (ECDSA) authentication to ensure enhanced protection and secure access to the service.

This security feature aims to protect the service while guaranteeing its availability to all clients. EigenDA's free tier offers a throughput of up to 768 kilobytes per 10-minute window, far exceeding the needs of even the busiest rollups on Ethereum. EigenDA also allows partners to request increased throughput beyond the free tier, providing a flexible solution for high-demand use cases.

EigenLayer is also working on implementing permissionless payments for blob throughput on EigenDA, which is planned to be released by the end of 2024. This feature will enable users to reserve bandwidth at a fixed rate to support high throughput demands. Additionally, EigenLayer has completed the second phase of its EIGEN token airdrop, contributing to the total distribution of 113 million EIGEN tokens.
