Introduction and Background

The rise and popularization of Layer 2 or L2 blockchains have been a significant development in the blockchain space. The growth of L2’s is driven by the need for scalability and improved user experience. As the adoption of dApps and DeFi protocols surged, L1 blockchains like Ethereum faced challenges with high gas fees and network congestion. These issues make them less practical for everyday transactions.

L2 blockchains emerged as a solution to these scalability issues. They are essentially secondary chains that operate in conjunction with L1 chains, leveraging their security while providing faster and cheaper transactions. One of the key technologies enabling L2 solutions is rollups. Rollups are Layer 2 scaling techniques that batch multiple transactions together and submit them as a single transaction to the L1 blockchain.

Arbitrum and Optimism are two popular L2 solutions that use rollup methods. Arbitrum employs Optimistic rollups, where transactions are initially executed off-chain, and then a cryptographic proof is submitted to the L1 blockchain to ensure their validity. This method significantly reduces gas costs and enhances throughput without sacrificing security.

One of the newer and promising L2 blockchains is Base, a chain developed by CoinBase, one of the leading cryptocurrency exchanges.  

What is the Base Blockchain?

Base is an L2 blockchain developed by Coinbase, utilizing Optimism's OP Stack technology, and built on top of the Ethereum blockchain. This innovative solution aims to offer a more scalable and cost-effective environment for dApps.

One of the primary advantages of Base is its security, as it relies on the Ethereum blockchain's robust security measures. In addition to enhanced security, Base boasts remarkable scalability, capable of processing a significantly higher number of transactions per second than Ethereum L1. This aspect is particularly attractive for dApps that require frequent and high-volume transactions.

Another key benefit of Base is its cost-effectiveness. Transactions on the Base blockchain are notably cheaper compared to Ethereum L1, making it more accessible and affordable for users to interact with dApps.

Although still in development, Base has garnered substantial attention due to its promising features and backing from Coinbase. Base allows for community contributions, fostering a collaborative environment for further development.

The foundation of Base's capabilities lies in its roll-up architecture, enabling scalability and cost-effectiveness. By batching transactions together and submitting them to the Ethereum blockchain in a single batch, Base significantly reduces transaction costs and enhances network throughput.

Moreover, Base is EVM-compatible, allowing seamless migration of dApps from Ethereum to Base without the need for extensive code rewriting. This developer-friendly approach encourages more developers to build on Base and further enrich the blockchain ecosystem.

Coinbase - Background on Base’s Creator

Coinbase offers cryptocurrency exchange services, allowing users to buy, sell, and trade cryptocurrencies. With a vast user base of over 68 million individuals across more than 100 countries, Coinbase has established itself as one of the leading cryptocurrency exchanges worldwide.

The platform offers a diverse range of features, encompassing the ability to buy and sell cryptocurrencies using fiat currencies such as USD, EUR, and GBP.

To ensure the security of users' digital assets, Coinbase also provides a secure wallet for storing cryptocurrencies.

As a regulated exchange, Coinbase adheres to the laws and regulations of the jurisdictions in which it operates, making it a reliable and safe platform for cryptocurrency transactions and storage.

However, there are some considerations to bear in mind. Coinbase's fees can be relatively high, particularly for smaller transactions. Furthermore, Coinbase is not available in all countries, limiting its accessibility in certain regions.

How Does the Base Blockchain Work? 

The Base blockchain operates as an L2 solution that is layered atop the Ethereum blockchain. Base leverages Optimism's OP Stack technology to achieve scalability and cost-effectiveness.

In the Base blockchain, transactions are processed off-chain, ensuring that they do not directly interact with the Ethereum blockchain. Instead, these transactions are batched together and collectively submitted to the Ethereum blockchain. This batching mechanism substantially alleviates the burden on the Ethereum blockchain, enabling Base to process a significantly higher number of transactions per second.

Once a batch of transactions is submitted, it undergoes validation by a group of validators. If the batch is deemed valid, it is added to the Ethereum blockchain, and the users who initiated the transactions are rewarded for their contributions.

To maintain the integrity of the transactions, Base employs a fraud-proof mechanism that relies on cryptographic hashes. Each time a new block of data is appended to the Base blockchain, its hash is stored in the previous block. This creates an immutable chain of hashes that ensures data in the blocks cannot be altered without modifying the hashes of all subsequent blocks, preserving the authenticity and security of the transactions.

In technical terms, Base's transactions are processed through rollups, off-chain batches, and validators verify and add these rollups to the Ethereum blockchain. The fraud-proof mechanism secures the system through a chain of cryptographic hashes that guarantee data integrity. This architecture presents Base as an advanced and promising L2 solution to tackle Ethereum's scalability challenges.

What are Base’s Blockchain Gas Fees?

Base's blockchain boasts significantly lower gas fees than Ethereum's L1, aiming to be less than $0.01 per transaction. Low fees ensure cost-effectiveness for users interacting with dApps. These lower gas fees are made possible through batching, where transactions are simultaneously grouped together and submitted to the Ethereum blockchain. Batching reduces the total number of transactions processed on Ethereum. 

Additionally, Base employs optimistic rollups, processing transactions off-chain and easing the Ethereum blockchain's burden, contributing to cost-effectiveness and scalability. The platform's fraud-proof mechanism, fortified by cryptographic hashes, safeguards transactions against tampering, avoiding gas fees for invalidated transactions due to fraud.

Notably, Base does not have its own native token, and gas fees are paid in ETH. These measures collectively embody Base's commitment to affordability, scalability, and operational efficiency, delivering a seamless user experience for interacting with dApps on the platform.

What are Base's Security Measures?

Base implements a robust set of security measures to safeguard its network and user data. Utilizing cryptography, including cryptographic hashes, Base ensures data integrity and uniqueness for blocks of information. 

Being open source allows scrutiny from the wider community, reinforcing the protocol's security through transparency and review. Beyond the measures mentioned, a bug bounty program that incentivizes security researchers to identify and disclose potential vulnerabilities. These comprehensive security measures demonstrate Base's unwavering commitment to providing a safe and trustworthy platform for its users.

What is the Base Bridge?  

The Base Bridge is a single asset blockchain bridge currently supporting ETH. 

During the developer access period, the Base Bridge UI ( is unavailable for mainnet, only accessible for testnet bridging.
