Some good news amid the recent regulatory turmoil, Base, an Ethereum Layer 2 (L2) powered by the OP Stack, is moving closer to its mainnet launch after successfully launching the Base testnet in February.
With a focus on safety and security, Base aims to provide a secure and cost-effective platform for developers worldwide to build decentralized applications (dApps) on the blockchain.
During the Base Builder Quests campaign, which witnessed a surge in contract deployments on the Base testnet, the project encountered challenges related to scalability and performance.
This surge of data-heavy transactions exposed issues with L2 data management, particularly concerning unique data management and synchronization with the Layer 1 (L1) Ethereum network.
The surge in contract creations led to a backlog of pending data, causing delays in processing and synchronizing L2 blocks with the L1 network.
This issue had not been observed in a mainnet environment before, but it provided an opportunity for the Base team to identify and implement solutions that could enhance the scalability of the OP Stack.
To counteract this, adjustments were made to compression ratios, gas limits, and the number of confirmations required for writing L2 batches to L1.
Despite these adjustments, the system initially struggled to reach equilibrium, resulting in a significant number of uncommitted blocks.
However, as the Base Builder Quests campaign slowed down, the team managed to close the gap and bring the system back into balance.
For a long-term solution, the Base team implemented two changes to the batcher, which improved the throughput of the system. Firstly, they introduced an improved compression implementation for better utilization of L1 transaction call data.
Secondly, they enabled the submission of multiple batch transactions per L1 block, instead of processing them one at a time. Load testing indicated that these changes increased the butcher’s throughput by up to five times, limited only by the capacity of L1 blocks.
These improvements not only enhance the scalability of Base and the OP Stack but also offer several benefits for users at the mainnet. The changes pave the way for increasing block gas limits, ensuring low base fees, and maintaining accessibility as demand for block space grows.
Additionally, the changes help maintain synchronization between safe and unsafe blocks, facilitating faster transactions and withdrawals on custodial exchanges that rely on up-to-date safe blocks.
The team behind Base brings years of experience in scaling cryptocurrency from their work at Coinbase. With a focus on scaling Base and the OP Stack, they are determined to empower the next generation of crypto by attracting millions of developers and billions of users to the blockchain.
