How Does Base Chain Work?

Base Chain utilizes an optimistic rollup mechanism to achieve faster transaction speeds and lower fees compared to the Ethereum mainnet. Here’s a breakdown of how it works:

Core functionalities:

➤ Off-chain transaction processing: Similar to other optimistic rollups, Base Chain moves a significant portion of transaction processing off the Ethereum mainnet. This significantly reduces the load on the mainnet, allowing it to focus on securing the overall network and finalizing transactions.

➤ Batching transactions: Transactions submitted by users are grouped into batches. Processing transactions in batches leverages economies of scale, spreading the fixed costs associated with each transaction across a larger group. This results in lower fees for users compared to processing each transaction individually on the mainnet.

➤ Fraud proofs and security: Base Chain inherits security from the Ethereum mainnet through the optimistic rollup mechanism. Transactions are assumed to be valid by default. This allows for faster processing speeds. A challenge period exists after a block of transactions is submitted to the mainnet. During this period, anyone can dispute a fraudulent transaction by submitting a fraud proof.

➤ Fraud proof construction: A fraud proof is a cryptographic argument that demonstrates a specific transaction within a block is indeed invalid. Constructing a valid fraud proof requires knowledge of the optimistic rollup’s rules and cryptographic expertise.

➤ Mainnet validation and finalization: If a valid fraud proof is submitted during the challenge period, the Ethereum mainnet can revert the entire block containing the fraudulent transaction. This ensures the security of the rollup system. If no valid challenge arises, the transactions in the block are considered valid, and the mainnet finalizes the block, updating the rollup’s state.

Base Chain vs. Other Blockchains

Comparison with Other L2 Solutions for Ethereum (e.g., Arbitrum, Optimism):

Similarities:

All are L2 solutions designed to address scalability issues on the Ethereum mainnet by processing transactions off-chain. They all inherit security from the Ethereum mainnet.

Differences:

• Technical approach: There are various technical approaches to L2 solutions. Both Arbitrum and Optimism (the foundation for Base Chain) utilize optimistic rollups, while other solutions might explore different mechanisms like zk-rollups (zero-knowledge rollups).
• Decentralization: Current level of decentralization can vary among L2 solutions. Both Arbitrum and Base Chain are relatively young and have plans for gradual decentralization. Optimism, the foundation for Base Chain, is already more established in this regard.
• Focus: While all aim for scalability, there can be a focus on specific use cases. Arbitrum might cater more towards high-performance DeFi applications, while Base Chain positions itself with a focus on developer experience and user adoption.

Base Chain vs. Ethereum

Core Purpose:

• Ethereum: A well-established Layer 1 (L1) blockchain known for its smart contract functionality and fostering a vast ecosystem of decentralized applications (dApps). However, it suffers from scalability issues leading to slow transaction speeds and high fees.
• Base Chain: An Ethereum Layer 2 (L2) scaling solution built on top of Optimism’s OP Stack. It aims to address Ethereum’s scalability limitations by processing transactions off-chain, offering faster speeds and lower fees.

Base Chain Metrics

Base Chain, being a relatively new entrant in the L2 space (launched August 2023), is still establishing its track record. Here’s a look at some key metrics to gauge its current state (as of April 3, 2024):

Total Value Locked (TVL):

• TVL is a commonly used metric to assess the value of assets locked within a DeFi ecosystem.
• Base Chain boasts a TVL exceeding $3.14 billion, placing it third among rollup solutions according to sources like BeInCrypto: [invalid URL removed]. This indicates a significant amount of capital flowing into the Base Chain ecosystem.
• It’s important to note that the TVL growth for Base Chain has been remarkable, with some sources reporting a rise of over 1400% since launch in July 2023

Transaction volume and fees:

• While specific data on daily or weekly transaction volume might be harder to find for Base Chain compared to established players, some positive signs exist.
• Reports suggest Base Chain has surpassed other L2 solutions in terms of daily active address ratio, indicating a higher user engagement rate despite a potentially smaller user base . There are also reports of Base Chain processing transactions at a rate exceeding the Ethereum mainnet at times
• Transaction fees on Base Chain are expected to be significantly lower compared to the Ethereum mainnet due to the L2 nature of the solution. However, specific fee structures might still be under development, so consulting official Base Chain documentation or community resources is recommended for the latest information.
