SUI is a base layer protocol with native parallel execution, while Arbitrum is an L2 scaling solution for Ethereum relying on rollups. Each addresses scalability differently, so their approaches suit distinct roles in the ecosystem
A base layer blockchain like SUI operates on its own network and consensus, handling security and transactions directly, while L2 like Arbitrum builds atop a base layer (e.g., Ethereum), leveraging its security to scale transaction throughput without altering the base layer's fundamentals
Some of the most popular L2s are Arbitrum and Optimism, with zkSync and StarkNet gaining traction through innovative scaling with zero-knowledge proofs and other tech advances
SUI's mainnet launched in mid-2023, with the first block mined during its initial rollout phase, marking the protocol's debut on the blockchain scene
How does SUI differ from the Arbitrum blockchain?
SUI is a base layer protocol with native parallel execution, while Arbitrum is an L2 scaling solution for Ethereum relying on rollups. Each addresses scalability differently, so their approaches suit distinct roles in the ecosystem
What is the difference between base layer and L2?
A base layer blockchain like SUI operates on its own network and consensus, handling security and transactions directly, while L2 like Arbitrum builds atop a base layer (e.g., Ethereum), leveraging its security to scale transaction throughput without altering the base layer's fundamentals
What are the most popular L2 on Ethereum?
