The developers at Zerion have rolled out the mainnet for their L2 blockchain, ZERO, enabling wallet users to issue, trade, and transfer tokens without gas fees, powered by zero-knowledge proof (ZK) technology.

Uniswap, the decentralized exchange, has revealed its proprietary L2 blockchain, Unichain, developed using the OP Stack from Optimism. According to the development team, this initiative is part of a strategy to enhance Ethereum’s scalability, leading to a major increase in payment efficiency.

Sony Block Solutions Labs, a collaborative venture between Sony Group and Startale, announced the launch of a new public L2 blockchain named Soneium, built on Optimism's OP Stack. This blockchain will be a part of the Superchain ecosystem. The testnet is set to be released in the upcoming days, with Sota Watanabe leading the project.

The Celo Foundation, the entity behind the L1 blockchain Celo, has successfully launched the Dango L2 testnet. Developed on the OP stack, Dango is now part of the Optimism Superchain ecosystem, which includes other projects like Base and Zora. The deployment of this L2 blockchain is a key component of the community's plan for migration to Ethereum.

Sonic, a second-layer gaming blockchain built on Solana, has raised $12 million in its latest funding round, reaching a diluted valuation of $100 million. Prominent venture firms like Bitkraft Ventures, Galaxy Interactive, OKX Ventures, and others participated in the investment.

L2 blockchain zkSync has launched the ZK Nation community, designed to govern, protect, and develop the ZKsync protocol.

Matter Labs, the entity behind the L2 network zkSync, has decided not to pursue trademarking the term "ZK" following resistance from the cryptocurrency community.

Ethereum founder Vitalik Buterin published the 4th part of his vision for the possible futures of the blockchain. Recently, he outlined an ambitious goal of achieving 100,000 transactions per second for Ethereum, alongside L2 networks.

L2 blockchain Scroll, which leverages zk-rollup technology, has revealed the specifics of its upcoming SCR token airdrop. The airdrop will take place alongside the Token Generation Event (TGE), scheduled for October 22, 2024.

On October 9, 2024, the Optimism L2 blockchain team announced their 5th airdrop. As part of this event, 10.2 million OP tokens (roughly $16 million at current prices) will be distributed to 54,000 users.

On September 12, Vitalik Buterin wrote on X that starting next year, he will no longer publicly mention L2 projects that haven't reached at least Stage 1 of his rollup milestones, which he introduced in 2022.

Worldcoin has introduced its L2 blockchain, World Chain, for a limited number of developers to test and give feedback before the mainnet launch by the end of summer 2024. Developers can also pre-deploy their applications.

Sources from DLNews reveal that the L2 blockchain ZKsync developers have committed about 0.5% of all issued tokens to the decentralized social network Lens Protocol to ensure its launch on their platform. Although the precise number is undisclosed, it’s estimated to be around 100 million ZK ($22 million at current market value).

The Ethereum ecosystem, including its L2 and L3 blockchains, has set a new record for transactions per second at 245 TPS. A significant portion of this achievement, nearly 50% or 101 TPS, was contributed by the relatively new gaming-focused L3 blockchain, Xai, even though its total value locked (TVL) is less than $2 million.

Polygon Labs, a crypto company, has acquired the research platform Toposware, which aided developers in creating Polygon Type-1 — a project allowing any EVM network to become an L2 blockchain with zero-knowledge (ZK) proof. The deal is estimated to be worth between $30 million and $50 million, according to various sources.

Taiko has officially launched its L2 network on the mainnet. Taiko is an Ethereum-equivalent, EVM-compatible L2 blockchain utilizing ZK-rollup technology.

Neel Somani, CEO and founder of the L2 blockchain Eclipse, has temporarily reduced his public involvement in the project amidst numerous allegations of sexual harassment. He believes this step will help protect the project's reputation and minimize damage to other members of the ecosystem.
