Movement Labs targets 1-second L2 finality by end of 2024: Co-founder

Apps will be able to settle directly on Movement’s L2 with fast finality ‘postconfirmations’ secured by stakers, the co-founder said.

Movement Labs aims to launch a new mechanism for quickly settling transactions directly on layer 2 (L2) scaling networks by the end of 2024, Rushi Manche, Movement’s co-founder, told Cointelegraph in an interview.

Fast finality ‘postconfirmations’ are an alternative to existing methods for settling Ethereum (ETH) L2 transactions — such as zero-knowledge (ZK) and fraud proofs — with the potential to cut confirmation times to less than 1 second, Movement said in a Sept. 2 blog post. 

Total value locked (TVL) on L2s has more than tripled in 2024 to almost $35 billion, according to L2Beat, as Ethereum’s surging popularity strains the network’s limited bandwidth.

Celestia unveils roadmap to 1-gigabyte blocks

The roadmap comes amid fierce competition in data availability among rivals such as EigenDA and Avail.

Celestia, a layer-1 data availability network, unveiled a technical roadmap charting a path to scaling block size to 1 gigabyte, according to a Sept. 5 blog post.

The roadmap’s core objective is to “relentlessly scale to 1-gigabyte blocks, bringing a massive increase in data throughput to Celestia’s rollup ecosystem,” Celestia said. Blocks are bundles of transaction data grouped together on blockchain.

Celestia’s focus on block size reflects an industrywide push to enhance the scalability of blockchain networks by lowering transaction costs and more efficiently storing and retrieving data. Celestia competes with protocols such as EigenDA and Avail, as well as mainnet Ethereum.

EigenLayer rolls out ‘major update’ to restaking contracts

The upgrade aims to enhance rewards for restakers. 

Eigen Labs, the developer behind EigenLayer, deployed a “major update” to the restaking protocol aimed at “making native [Ether] restaking on EigenLayer easier and more rewarding,” according to a Sept. 4 blog post.

The upgrade is designed to improve the performance of so-called EigenPods — EigenLayer’s restaking smart contracts for Ether (ETH) staked on Ethereum’s Beacon Chain — by granting users greater flexibility in harvesting or reinvesting staking rewards. 

“EigenPod users can now complete a checkpoint to restake their beacon chain ETH rewards on top of their existing EigenPod balance,” Eigen Labs said. “Beacon chain rewards are automatically restaked back into EigenLayer, enabling restakers to earn additional rewards.”

EigenLayer enhances EigenDA security to combat Sybil attacks

With the additional security feature, EigenLayer aims to protect the service it offers while guaranteeing its availability to all clients.

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.
