Solving the blockchain trilemma with decentralized scalability

This special episode of Decentralize with Cointelegraph dives deep into Ethereum layer-2 scaling solutions with Jose Fabrega, head of marketing at Metis — a rapidly growing Ethereum layer-2 rollup —and the goal to make Ethereum a more scalable and decentralized place to build.

Can Ethereum handle the rush?

The blockchain world is booming, but Ethereum, one of the most popular networks for decentralized applications, faces a scalability challenge. 

Fabrega encourages listeners to think of the network as a super secure highway where traffic builds during peak hours — like during the launch of a popular nonfungible token project. Transactions can take minutes to complete and cost users substantial fees, sometimes 10s or even hundreds of dollars. This hinders the user experience and limits the network’s ability to handle the ever-growing demand for real-world applications.

To address Ethereum’s scaling challenges, developers have created layer-2 solutions. These solutions can be considered “new lanes” on the Ethereum highway for collective vehicles.

On Metis, transactions are bundled together and processed quickly and cheaply without compromising the security of the underlying Ethereum blockchain. Layer-2 solutions like Metis take transactions off the main Ethereum network, decongesting it and allowing for faster and cheaper transactions.
