Base

Introduction to Base

Base represents the most significant entry of traditional finance into blockchain infrastructure. Launched in August 2023 by Coinbase, the largest publicly traded cryptocurrency exchange, Base is an Ethereum Layer 2 network built to bring the next billion users to the blockchain. Unlike most L2s that cater primarily to crypto-native users, Base explicitly targets mainstream adoption through Coinbase’s 100+ million verified users and established relationships with enterprises and regulators.

Built on Optimism’s open-source OP Stack, Base uses optimistic rollup technology to provide fast, low-cost transactions while inheriting Ethereum’s security. The network’s integration with Coinbase’s platform - including seamless on-ramps, smart wallets, and developer tools - positions it as potentially the most accessible entry point for new users entering the blockchain ecosystem.

The Strategy Behind Base

Coinbase’s Blockchain Vision

Coinbase’s decision to build Base reflects a strategic evolution from exchange operator to infrastructure provider. CEO Brian Armstrong has long articulated a vision of making cryptocurrency accessible to everyone, but exchange services alone cannot achieve this goal. By operating a Layer 2 network, Coinbase can:

• Reduce friction for users moving from exchange to on-chain activity
• Capture value from on-chain transactions beyond trading fees
• Offer developers a platform with built-in distribution
• Shape the technical and regulatory standards for blockchain infrastructure

Why Not Build an L1?

The decision to build on Ethereum rather than create an independent Layer 1 was deliberate. Coinbase recognized that:

• Ethereum’s security and decentralization are proven over nearly a decade
• The EVM ecosystem provides the largest developer and application base
• Regulatory clarity is further advanced for Ethereum-based assets
• Interoperability with Ethereum DeFi is essential for user adoption

How Base Works

Optimistic Rollup Architecture

Base uses optimistic rollup technology, meaning it assumes transactions are valid unless proven otherwise. Key components include:

Sequencer: Base operates a centralized sequencer that orders transactions and provides instant “soft” confirmations. While centralized, the sequencer cannot forge transactions or steal funds - it can only temporarily censor or reorder transactions.

Data Availability: Transaction data is posted to Ethereum (using blobs after the Dencun upgrade), ensuring anyone can reconstruct Base’s state and verify correctness.

Fraud Proofs: A 7-day challenge period allows anyone to submit fraud proofs if invalid state transitions are detected. Successful challenges revert the invalid transactions.

The OP Stack Foundation

Base is built on the OP Stack, Optimism’s modular, open-source rollup framework. This provides several advantages:

• Shared Development: Improvements to the OP Stack benefit all networks using it
• Superchain Compatibility: Base participates in the “Superchain” vision of interoperable L2s
• Proven Technology: The OP Stack powers Optimism’s mainnet with billions in TVL
• Upgrade Path: Base benefits from ongoing protocol improvements

Smart Contract Execution

As an EVM-compatible network, Base supports the full range of smart contract functionality:

• Deploy existing Solidity contracts without modification
• Use familiar tooling: Hardhat, Foundry, Remix
• Access established libraries and patterns
• Integrate with existing oracles and infrastructure

Technical Specifications

The No-Token Decision

Unlike most Layer 2 networks, Base has explicitly stated it will not launch a native token. This decision has significant implications:

Advantages

• Simpler user experience: No additional token to acquire or manage
• Regulatory clarity: Avoids potential securities concerns
• Focus on utility: Success measured by usage, not token price
• Ethereum alignment: Reinforces ETH as the network’s primary asset

Trade-offs

• No token-based governance: Community governance must use other mechanisms
• Limited incentive tools: Cannot use token incentives for bootstrapping
• Revenue model questions: Long-term sustainability relies on transaction fees
