Understanding and Adopting Layer 2 Solutions

Layer 2 solutions are technologies that enhance the scalability, security, and functionality of blockchain networks like Ethereum without changing the underlying Layer 1 protocol.

They allow developers to build more complex dApps while improving user experience through lower fees and faster transactions.

One popular type of Layer 2 solution is Optimistic Rollups, which are particularly attractive due to their ability to maintain security, offer a high degree of compatibility with existing Ethereum smart contracts, and provide substantial scalability improvements.

Here, we will explore why developers should consider Optimistic Rollups with case studies like Arbitrum, Optimism, and Goshen Network.

A Closer Look at Layer 2 Solutions: Arbitrum, Optimism, and Goshen Network


Arbitrum is a Layer 2 scaling solution that utilizes Optimistic Rollups to enable scalable and secure smart contracts on Ethereum.

Its architecture is based on the WebAssembly (WASM) instruction set and features an interactive challenge fraud proof system. This allows for efficient and secure dispute resolution while maintaining compatibility with the Ethereum Virtual Machine (EVM).

Real-world example: GMX, a decentralized perpetual futures exchange, has deployed its platform on Arbitrum to offer users faster transactions, reduced gas fees, and improved liquidity management.


Optimism is another Layer 2 scaling solution that employs Optimistic Rollups for smart contracts.

It uses the MIPS instruction set and is implemented in Golang. While its fraud proof system is still in design, Optimism maintains EVM-equivalent compatibility, allowing for seamless integration with existing Ethereum dApps.

Real-world example: Synthetix, a decentralized platform for synthetic assets, has integrated Optimism to enhance the scalability and performance of its trading platform. Synthetix allows users to mint and trade synthetic assets, such as cryptocurrencies, commodities, and equities, in a decentralized manner.

Goshen Network

Goshen Network is an Ethereum-specific Optimistic Roll-up Layer 2 solution that uses the RISC-V instruction set and is implemented in Rust.

It features a collaborative interactive challenge fraud proof system, enabling challengers to cooperate and share rewards. This design makes Goshen Network resilient to attacks that are conspired by the proposer and one challenger.

Although Goshen Network is still in its early stages, it has the potential to support various dApps, from decentralized finance (DeFi) to gaming and beyond.

Arbitrum and Optimism both utilize Golang for their state transition implementation, which results in a large executable bundled with a heavy go runtime.

In contrast, Goshen Network’s state transition is implemented in Rust, creating a tiny and efficient executable. Additionally, the instruction sets differ between these Layer 2 solutions: Arbitrum uses WebAssembly (WASM), Optimism uses MIPS, and Goshen Network employs RISC-V.

The Perks of Playing with a Multi-Chain Approach

Building Bridges for Interoperability

Multi-chain solutions like Ontology’s triple-chain ecosystem enable different blockchain networks to communicate smoothly, allowing assets and data to move seamlessly between them.

The Ethereum Virtual Machine (EVM) Chain acts as a bridge linking the Ontology Native Chain and the bustling Ethereum ecosystem, paving the way for even more collaboration and data-sharing adventures. This interoperability unlocks new possibilities for cross-chain applications, fostering innovation and breaking down barriers between various blockchain networks.

Mix and Match for Flexibility

Multi-chain solutions offer developers the flexibility to mix and match features from different blockchain networks, enabling them to create unique and customized applications.

With Ontology’s Native Chain focusing on decentralized identity and trust, and the EVM Chain connecting to Ethereum’s vast developer community and smart contract capabilities, developers have access to a rich toolbox of features. This flexibility empowers them to build groundbreaking projects that leverage the best of both worlds, creating new and exciting user experiences.

Supercharged Scalability

Scalability remains one of the most significant challenges in the blockchain space.

Ontology’s triple-chain ecosystem features the Goshen Network, an Ethereum-specific Optimistic Roll-up Layer 2 solution that moves some transactions off the main Ethereum network.

By offloading part of the transaction processing burden, congestion on the main network is reduced, and throughput is increased. The result is a faster and smoother user experience, with lower fees and shorter confirmation times, making it more attractive for developers and users alike.

Fortifying with Security

Security is a top priority in the blockchain world, and multi-chain solutions offer developers the opportunity to fortify their projects by leveraging the best security features each chain has to offer.

By combining multiple chains, developers can build their projects within a secure environment, benefiting from various consensus mechanisms, fraud-proof systems, and other security measures that each chain provides.

This robust security infrastructure helps protect users’ assets and data while ensuring the integrity of the applications built on top of these networks.

Challenges and Limitations

While Optimistic Rollups and multi-chain solutions offer numerous benefits, it’s essential to consider potential challenges and limitations when adopting these technologies.

For instance, Optimistic Rollups may experience longer withdrawal times due to the need for fraud proofs, and some dApps may require additional work to adapt to a rollup environment. Additionally, multi-chain solutions may face challenges in ensuring seamless cross-chain communication and maintaining a high level of security when interacting with multiple blockchain networks.

Despite these challenges, developers and researchers are continuously working to improve and refine these technologies, making them more robust and user-friendly.

Closing Thoughts

In conclusion, multi-chain approaches like Ontology’s triple-chain ecosystem bring a wealth of advantages, from increased interoperability and flexibility to improved scalability and security. By harnessing these benefits, developers can create innovative and groundbreaking projects that push the boundaries of what’s possible in the blockchain space, ushering in a new era of decentralized applications and digital experiences.

Are you ready to dive into the world of Optimistic Rollups and multi-chain solutions? Now is the perfect time to start exploring these technologies, joining their respective communities, and even beginning to develop your projects using these cutting-edge solutions. Embrace the exciting possibilities that lie ahead and become a part of the future of blockchain innovation!
