How does Base network compare to other Ethereum L2 networks?

Base network is one of the newest Ethereum L2 networks, and it has some similarities and differences with other L2 networks. Here are some of the main points of comparison:

  • Base network uses Optimistic Rollup as its scaling technology, which is the same as OP Mainnet, Arbitrum One, Arbitrum Nova, Boba Network, Layer2.Finance, and Zora Network. Optimistic Rollup relies on fraud proofs to ensure the validity of transactions on L2, and requires a one-week withdrawal period to exit L2 to L1. Optimistic Rollup can support any type of smart contract or dapp on Ethereum, but it has some limitations in terms of composability and interoperability with other L2 networks.

  • Other L2 networks use ZK Rollup or Validium as their scaling technologies, which are different from Optimistic Rollup. ZK Rollup and Validium rely on validity proofs to ensure the validity of transactions on L2, and do not require a withdrawal period to exit L2 to L1. ZK Rollup and Validium can offer faster and cheaper transactions than Optimistic Rollup, but they have more technical challenges in supporting general smart contracts or dapps on Ethereum. Some examples of ZK Rollup or Validium networks are zkSync, dYdX, Immutable X, Loopring, Starknet, Polygon zkEVM, ApeX, Sorare, Aztec Connect, DeGate, and Aztec.

  • Base network is integrated with Coinbase products, such as Coinbase Wallet and Coinbase Pro, which makes it easy for users to access and interact with dapps on Base network. This is a unique feature of Base network that other L2 networks do not have. However, Base network is still in beta stage and has not launched its mainnet yet, so it may not be as stable or secure as other L2 networks that have been running for longer.

  • Base network supports gasless transactions, meaning that users do not have to pay fees for sending or receiving transactions on Base network. This is similar to some other L2 networks that also offer gasless transactions, such as zkSync Lite, ZKSpace, Metis Andromeda, Canvas Connect, and Fuel v1. However, gasless transactions do not mean free transactions, as there are still costs involved in running the L2 network and posting data to Ethereum. These costs are either subsidized by the L2 network operators or passed on to the dapp developers or users in other ways.
