The Fantom platform is designed to be compatible with existing smart contract platforms such as Ethereum, Avalanche, and Arbitrum. This means that developers can build decentralized applications (dApps) on Fantom without having to learn a new programming language.
About Arbitrum
Arbitrum is a Layer 2 protocol for building decentralized applications that is scalable, private, and secure. Arbitrum enables developers to build apps that are resistant to tampering and censorship, while remaining fast and lightweight. The Arbitrum protocol is based on Ethereum, making it compatible with existing Ethereum tools and infrastructure. Arbitrum is developed by a team of researchers at the University of California, Berkeley.
The Arbitrum protocol is designed to address two of the major challenges facing Ethereum and other blockchain platforms: scalability and privacy. Arbitrum's unique design enables transactions to be processed off-chain, without compromising security or decentralization. This allows Arbitrum apps to scale without sacrificing trustlessness or censorship resistance.
