List of the Top 6 Layer 2 Protocols for Ankr in 2025

A community dedicated to open-source development is committed to improving Bitcoin's scalability, particularly in relation to its proof-of-work security, to meet global demands and adapt to new applications, while also honoring the core principles upon which Bitcoin was built. Over the past ten years since its mainnet debut, Syscoin has established itself as a frontrunner in providing a resilient network and protocol designed for projects aiming to leverage Bitcoin Layer 2 solutions. As a Bitcoin Layer 2 operating directly on the mainnet, Syscoin implements a data availability protocol that facilitates the deployment of EVM and AltVM rollups on the Bitcoin blockchain. By being merge-mined by a substantial portion of Bitcoin's hash rate, Syscoin effectively ties these rollups to the reliability of Bitcoin's proof-of-work system, allowing for a smooth integration with the existing sequencer frameworks of these rollups. Furthermore, Syscoin offers a scalable data availability layer crucial for rollups and other EVM or AltVM platforms, enabling them to connect to Bitcoin’s network in a secure and efficient manner. This pioneering strategy not only increases Bitcoin’s functionality but also solidifies its role in the rapidly changing world of cryptocurrencies, paving the way for future innovations and broader adoption. As such, Syscoin is not only a participant in the ecosystem but also an influential driver of Bitcoin's ongoing evolution.

Launch your decentralized applications on a modular cloud that is specifically crafted for practical application and tailored to meet your unique requirements. SKALE Networks presents a revolutionary modular protocol that empowers developers to easily construct highly customizable blockchains, ensuring the benefits of decentralization while providing strong computation, storage, and security features. These flexible blockchains are efficient and maintain their decentralized nature, while also being fully compatible with Ethereum, utilizing state-of-the-art advancements in modern cryptography to ensure safety. By adopting Byzantine Fault Tolerance (BFT), the system guarantees that consensus is achievable even if a third of the participants behave maliciously. Similar to how the Internet functions, this protocol considers the latencies of both nodes and the network, allowing messages to be delivered with the flexibility of delays. Additionally, BLS Threshold Signatures not only promote smooth interchain communication but also improve randomness in node allocation, ultimately leading to a more robust network. This forward-thinking methodology opens the door to a transformative phase in the deployment of decentralized applications, enhancing both efficiency and security in the process.

Celer Network functions as a layer-2 scaling solution aimed at enabling fast, secure, and affordable blockchain applications on Ethereum, Polkadot, and multiple other blockchain systems, with the goal of achieving widespread usage. It was the first to introduce a Generalized State Channel Network and remains at the forefront of innovation in the layer-2 scaling landscape through its sophisticated Rollup technology. The platform has generated significant attention due to its notable applications and middleware like cBridge and Layer2.Finance, as well as various ecosystem initiatives that appeal to a wide range of users in sectors such as DeFi, blockchain interoperability, and gaming. Layer2.Finance specifically targets the two main barriers to DeFi's broader acceptance: high transaction costs and complicated user interfaces. Furthermore, cBridge functions as a flexible multi-chain network that allows for instant, affordable, and smooth value transfers across different Ethereum layer-2 networks, the Ethereum main chain, and plans to support additional layer-1 and layer-2 solutions in the future. As Celer Network continues to grow, it is committed to improving the overall user experience and expanding access to blockchain technology for an ever-wider audience, fostering a more inclusive digital economy.

Develop decentralized applications that provide exceptional user experiences by harnessing the unparalleled security of Ethereum via our sophisticated layer-2 network built on a modular framework. Experience remarkable transaction speeds combined with robust security, all while utilizing Ethereum's roll-up technology in an environment that is fully compatible with the Ethereum Virtual Machine. The Mantle Liquidity Staking Protocol (LSP) represents a vital component of the Mantle ecosystem, enabling users to stake ETH and receive rewards in the form of mETH (Mantle Staked Ether). With a significant treasury under our management, we concentrate on delivering economic benefits for Mantle products, prioritizing value creation, transparency, and sound governance. Our unwavering dedication to these values guarantees that users can have confidence in the integrity and dependability of our ecosystem. Ultimately, this commitment to excellence fosters a thriving community that can actively participate in the burgeoning world of decentralized finance.

Blast stands out as the only Ethereum Layer 2 solution that provides built-in yield for both ETH and stablecoins, with its earnings originating from ETH staking and protocols involving real-world assets. This yield produced by decentralized networks is efficiently redistributed to Blast users. Unlike most Layer 2 solutions that maintain a standard interest rate of 0%, our objective as participants is to bolster the on-chain economy by creating the highest-yielding Layer 2 network possible. Community members who take part in this venture will have the chance to receive the Blast Airdrop. The potential of Blast was unlocked this year, thanks to the Ethereum Shanghai upgrade. Yield generated from Layer 1 ETH staking, initially via Lido, is automatically sent to users through a rebasing mechanism integrated into the Layer 2 network. By cultivating a thriving ecosystem, we aspire to draw in a larger user base and continue to push the boundaries of innovation within the decentralized finance realm, ultimately shaping the future of finance.

Scroll is specifically designed for Ethereum developers, acting as a swift, reliable, and scalable Layer 2 blockchain that enhances Ethereum's capabilities while enabling applications to grow effortlessly. It allows for a smooth transition of Ethereum applications to Scroll with bytecode-level compatibility, significantly reducing expenses in the process. Our focus on open development encourages collaboration among contributors who are driven by shared values, leading to the creation of more secure and well-architected systems. By prioritizing a community-focused approach, Scroll aspires to transform and progress the trajectory of Ethereum. Employing advanced zero-knowledge proof technology alongside established EVM frameworks and comprehensive audits, Scroll ensures that our platform is built on a foundation of security and dependability. Moreover, by emphasizing code security through joint open-source initiatives, Scroll protects both developers and users from potential threats, nurturing a resilient ecosystem for innovation. This commitment to security and community engagement not only strengthens our platform but also bodes well for the future of Ethereum as we strive to adapt and advance in the evolving digital landscape.
