Ethereum News Today: Ethereum’s L2s Unite: Privacy, Speed, and Unity Redefine Blockchain Future

Silent Data, an Ethereum Layer 2 developed by Applied Blockchain, has become the first privacy-focused blockchain to integrate with the Superchain, a network of over 30 Layer 2 solutions. The Superchain includes major projects such as Base by Coinbase, OP Mainnet, and Unichain by Uniswap. Silent Data utilizes the Optimism OP Stack and is designed to support blockchain applications while preserving data privacy through a “privacy wrapper” that enables sensitive operations to be executed on-chain without exposing private information. The project has already attracted interest from several companies, including Tokeny, Archax, Shell, and CRYOPDP, a subsidiary of DHL Health Logistics [3].

In parallel, Bitcoin has seen renewed interest in Layer 2 development. The project Bitcoin Hyper has raised over $13.5 million to fund a new Layer 2 network that aims to enhance Bitcoin’s functionality by integrating the Solana Virtual Machine (SVM). This integration allows for the execution of smart contracts and decentralized applications on Bitcoin, addressing a key limitation of the network. By enabling faster transaction speeds and programmability, Bitcoin Hyper aims to make Bitcoin more versatile for use in modern decentralized finance (DeFi) and digital asset ecosystems. The project’s native token, HYPER, plays a central role in governance, staking, and covering gas fees on the Layer 2 network [4].

The Ethereum Foundation (EF) has also announced significant developments to enhance the user experience across the Ethereum ecosystem, particularly in the area of Layer 2 interoperability. A new initiative called the Ethereum Interoperability Layer (EIL) aims to enable seamless transactions across multiple Layer 2 protocols, effectively making Ethereum feel like a single, unified chain. This initiative aligns with Ethereum’s core principles of censorship resistance, open-source development, and privacy. The EIL is designed to be trustless, ensuring that users retain control over their funds while enabling faster and more secure cross-L2 transfers. A design document for the EIL is expected to be published in October [5].

In a broader effort to streamline cross-chain transactions, the EF has outlined a three-phase roadmap to improve interoperability between Ethereum’s Layer 1 and Layer 2 networks. The first phase, known as "initialisation," focuses on developing the Open Intents Framework and the EIL, both of which aim to simplify user interactions by abstracting the complexity of multi-chain operations. The second phase, "acceleration," is centered on reducing transaction confirmation times. Ethereum currently requires 13–19 minutes for finality, but the goal is to bring this down to 15–30 seconds. The third phase, "finalisation," will explore deeper consensus mechanism changes to further reduce finality times, with a long-term aim of achieving near-instant settlement speeds [6].

To support this vision, the EF is also developing new Ethereum Improvement Proposals (EIPs) and ERC standards to standardize cross-chain asset handling and messaging. These include ERC-7828/7930 for interoperable addresses, ERC-7811 for asset consolidation, and ERC-7683 for common intent formats. These standards are intended to create a more cohesive and user-friendly environment for developers and end-users alike. Additionally, the foundation has emphasized the importance of privacy in the next generation of Ethereum wallets, with projects like the Kohaku wallet being explored as part of its 2026 roadmap [7].

The recent developments in Layer 1 and Layer 2 blockchain technology reflect a broader industry trend toward improving scalability, interoperability, and user experience. Projects such as Silent Data and Bitcoin Hyper are pushing the boundaries of what is possible with Layer 2 networks, while the Ethereum Foundation is working to unify the fragmented ecosystem through strategic upgrades and standardization. As these initiatives progress, they are expected to play a key role in shaping the future of decentralized applications and digital finance.
