Coinbase’s layer-2 network Base received Phase 1 decentralized status, announced Hsiao-Wei Wang, co-director of the Ethereum foundation. Base is one of the most widely used L2 chains linked to Ethereum, aiming to increase its tokenization activity.

Base was awarded Phase 1 status for its increased decentralization. The chain is one of the fastest and most scalable, but the Ethereum Foundation did not consider it one of the decentralized L2s.

Wang announced Base reached the Phase 1 milestone as an optimistic rollup chain, joining Arbitrum, Optimism and Unichain.

Base earned its Phase 1 status after launching permissionless fault proofs on its main net. This means anyone can start securing Base while coordinating with other nodes. The Phase 1 status is important, as Ethereum founder Vitalik Buterin has stated he will only track those types of chains in 2025.

The status of L2 depends on preset criteria for achieving consensus. Most of the newly created L2 chains use some form of centralized transaction sequencing. Base has fulfilled most of the criteria for decentralized consensus on network status, transactions, and sequencer failure.

A total of 154 L2 chains have already launched, with most starting operations with centralized consensus. Only a handful of L2 networks emerged as winners in terms of value locked and users. Base is among the sector’s leaders, due to its apps, value locked, and inflow of stablecoins.

Anyone can secure Base chain

The latest network upgrade for Base means anyone can propose a chain state, or issue transactions claiming to be legitimate.

To secure the network, decentralized users can run the free Challenger software package. If a user sends out a claim without proof, challengers can prove the transaction is invalid. As an incentive, challengers will receive the claim bond. Even one challenger can protect the chain from malicious transactions.

Base is planning another milestone, where network upgrades will also be approved by a decentralized council. Currently, upgrades are decided by the chain’s dedicated team

Base remains a key L2 chain for decentralized activity

Even without the technical upgrades, Base remained one of the key networks, promoted by Coinbase as the network for cheap on-chain fun. However, Base turned out to be one of the valuable chains for DeFi and perpetual DEX trading.

The upgrade arrived just a day after Ethereum announced its leadership restructuring plans. There are still discussions about the role of L2 networks, and still pressing question of scaling the L1 chain as well.

Base carries over 642K daily active users, achieving a high baseline for activity in 2025. The chain receives inflows from Ethereum, with up to $500K in daily netflows. Bridge inflows often reach $4.2B on a weekly basis, rising again in April.

Base secures over $2.96M in total value locked, with up to $3.8B from additional stablecoin liquidity. The chain is also growing its list of tokens, aiming to rival Solana with meme launches and DEX activity.
