EigenLayer Enhances Security with ECDSA Authentication


EigenLayer has implemented a whitelist security feature using ECDSA authentication to protect EigenDA data-availability service on the Ethereum mainnet against attacks. This security enhancement ensures accessibility to all customers while aiming to safeguard the service.


EigenLayer’s EigenDA service on the Ethereum mainnet has bolstered its security measures by introducing a whitelist security feature powered by ECDSA authentication. This enhancement is designed to protect against Sybil and distributed denial of service attacks, ensuring a secure and accessible platform for all users.

Main Points

The security mechanism in EigenDA leverages ECDSA authentication based on user IP addresses and Ethereum addresses, creating a robust layer of protection. The free tier of EigenDA offers significant throughput, exceeding the needs of Ethereum’s busiest rollups, with the capacity to handle up to 768KB every 10 minutes.

Partners can request additional throughput beyond the free tier, collaborating with EigenDA to meet their data requirements efficiently. EigenDA’s scalability allows for peak throughputs of 10 MB/sec on the mainnet and synthetic loads of 0.6 MB/sec, catering to diverse high-throughput use cases.

EigenLayer aims to introduce permissionless payments for blob throughput on EigenDA, enabling customers to secure bandwidth at fixed rates. This feature, set to launch by the year’s end, will provide flexibility for users with varying throughput needs, enhancing the service’s accessibility and usability.


With its enhanced security features and upcoming permissionless payment system, EigenLayer’s EigenDA is poised to offer a secure and efficient data-availability service on the Ethereum mainnet. The platform’s focus on scalability, flexibility, and accessibility ensures that it can meet the evolving needs of users in the blockchain ecosystem.
