Ethereum L2 blockchain LightLink uses Celestia as a data availability layer

On June 5th, the Hummingbird client side of the Ethereum L2 blockchain LightLink went live on the Celestia mainnet, publishing L2 data to Celestia DA and verifying, sending only block hairs to Ethereum. LightLink said that using Celestia as its data availability layer will reduce costs compared to Ethereum, allowing us to save costs for end users in the form of lower transaction fees.
