EigenLayer enhances EigenDA security to combat Sybil attacks

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.

According to an X post from EigenDA, 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.

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.

The security feature

With the additional security feature, EigenLayer aims to protect the service it offers 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. For instance, Base uses fewer than two blobs every 10 minutes.

Additionally, EigenDA allows partners to request increased throughput beyond the free tier, providing a flexible solution for high-demand use cases.

Through its partner registration page, interested parties can collaborate with EigenDA to tailor solutions for their data needs, supporting a wide range of applications and innovations requiring high-throughput capabilities.

EigenDA generates synthetic loads of 0.6 megabytes per second and achieves peak throughputs of up to 10 MB per second on the mainnet.

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.

Eigen’s token distribution

In May, EigenLayer completed the second phase of its EIGEN token airdrop, marking the end of its Season 1 and contributing to the total distribution of 113 million EIGEN tokens, amounting to 6.7% of the allocated supply for airdrops.

Once claimed, tokens will be temporarily locked until the end of the third quarter of 2024. However, users can still engage in staking and delegation activities with EigenDA operators through the EigenLayer web portal.

EigenLayer, which went live on the Ethereum mainnet in April 2024, has already gathered more than $12 billion in deposits. The platform opens up new proof-of-stake projects by using a wider trust network, thus omitting the necessity for separate security solutions.
