The ever-evolving world of blockchain technology continues to be a hotbed of innovation, and one of the latest trends in this area is the implementation of Layer-2s, and Coinbase’s latest Base.
Layer-2s promise improved transaction speeds, scalability and security and shift the paradigm of how blockchain networks work. Coinbase, North America’s largest centralized crypto exchange (CEX), has announced the launch of “Base”, a new layer-two (L2) Ethereum chain using Optimism. Let’s dive in.
Understanding layer 2s
At its core, Layer-2s are a type of blockchain architecture. They build on the fundamental base layer (or layer 1), which typically contains the protocol for a blockchain network such as Bitcoin or Ethereum, and add an additional layer to handle transactions and smart contracts.
The concept of layered architecture in blockchain is not new; what sets layer-2s apart is how they are designed to maximize efficiency and scalability without compromising security and decentralization. They address some of the critical challenges that base layer blockchains face, such as network congestion, slow transaction times, and high fees.
How do they work?
Layer-2s work by creating a second layer of protocols on top of the main blockchain. Transactions that would normally be processed on the primary blockchain are instead performed on this second layer. It’s like adding a freeway to a busy highway; transactions can be processed faster and more efficiently, bypassing the traffic on the main road.
The completed transactions on the second layer are then aggregated and added to the main blockchain as a single entry, reducing the load on the primary chain and significantly increasing the capacity of the overall network.
The remarkable thing is that all this is achieved while maintaining the decentralized nature and security of the blockchain. Transactions in the second layer are cryptographically linked to the base layer, ensuring the same level of security and trustless nature that blockchain technology is known for.
What is Basic?
Base is an L2 chain developed and managed by Coinbase, using Optimism’s framework – a layer-two scaling solution for Ethereum and the second largest L2 ecosystem after Arbitrum. Optimism’s primary goal is to address the blockchain trilemma – issues related to scalability, security and decentralization – by enabling interoperability and composability between the rollups, including Base.
Optimism wants to evolve into a “superchain” of L2 chains, allowing Ethereum to scale effectively. The superchain provides shared security and tools for developers to interact and create Optimism-compatible L2s that work with regular wallets. Coinbase and Optimism have been working together for over a year and have contributed to the development of EIP-4844, an Ethereum upgrade that could drastically reduce L2 transaction costs.
What the future holds for Base
In July, Base became available for developers to test their applications on the new network. According to a Coinbase blog post, users can now transfer their ether (ETH) to Base. The update coincides with Coinbase’s upcoming Q2 earnings report and the start of “Onchain Summer,” a series of events for creators and developers to create art or develop applications on Base. Participants include Coca-Cola, Atari and the non-fungible token platform OpenSea.
The launch marks Coinbase’s strategic commitment to web3 and L2 adoption, with a view to potential future revenue. Given the increasing demands of blockchain networks — whether for decentralized finance (DeFi), non-fungible tokens (NFTs), or myriad other applications — Layer-2s are emerging as an effective solution to improve scalability.
Base recently announced that the mainnet will be open to all users on August 9, providing a comprehensive platform to explore the various possibilities within blockchain technology.
According to Base, “Our mission remains unwavering: to usher in the next million builders and one billion users on-chain.”
