Is Arbitrum an Ethereum?

Arbitrum is a layer-2 scaling solution for Ethereum that uses optimistic rollUPS to improve scalability. It is not a fork of Ethereum, but rather a complementary protocol that can be used to scale Ethereum applications.

Arbitrum was created by Paul Sztorc, who is also the creator of the Truthcoin protocol. Sztorc is a well-known figure in the cryptocurrency space and has been involved in projects like BitShares, Drivechain, and Smart contracts 2.


Arbitrum is designed to be compatible with all existing Ethereum applications, which means that it can be used to scale any Ethereum-based project. The protocol is also backwards-compatible with Ethereum’s existing smart contracts.

One of the key features of Arbitrum is its use of Optimistic RollUPS. Optimistic RollUPS allow for off-chain computations to be verified on-chain, which improves scalability without sacrificing security.

Another key feature of Arbitrum is its use of Verifiable Delay Functions (VDFs). VDFs are cryptographic functions that can be used to create timestamps that are resistant to quantum attacks.

This makes Arbitrum more secure than other scaling solutions that do not use VDFs.

Arbitrum is still in development and is not yet ready for production use. However, the team behind Arbitrum is confident that the protocol will be ready for mainnet launch in 2020.

So far, Arbitrum has been well-received by the Ethereum community and has attracted a lot of attention from developers looking for a way to scale their applications. While Arbitrum is not an Ethereum fork, it is a complementary protocol that can be used to scale Ethereum applications.
