Missing figures stay unavailable. Forward P/E requires a dated source. Annual revenue, revenue growth, net income and margin come from each company's own 10-K, in US dollars, and each row shows that fiscal year. Revenue growth compares the fiscal year with the prior year stated in the same 10-K. Net income is the full year amount attributable to the company, or available to common stockholders where the filing states only that, or consolidated net income. Each row names its basis. Trailing P/E reads "Not meaningful" when the dated trailing diluted EPS is a loss or zero. An operating margin appears only when the filing states both the operating income and the revenue for the same year.

Sources: SEC filings, Gloria daily closes and CoinGecko. Oldest record refresh: Oct 27, 2026, 8:36 PM EDT. Refresh is not a price or filing date. Each row shows its price date and its annual fiscal period. Peers use industry code and company size, or editorial selection. Market cap multiplies that row price by the company share total the latest SEC filing states for every share class together. Trailing P/E divides it by trailing diluted earnings from SEC filings. Rolled earnings per share are approximate because share counts can change between periods. Both appear only when the SEC data carries its date, so they are estimates at one price date, not synchronized filing valuations. Not investment advice.

Base, Coinbase’s Ethereum Layer-2 network, went dark on June 25, 2026, when block production ground to a halt for more than an hour. The culprit was a consensus issue triggered by an invalid block sequence following block number 47,806,542.

Jesse Pollak, the lead builder for Base, publicly acknowledged the disruption and directed users to the official status page as the team worked through its investigation. His message was clear on one point: no user funds were at risk.

The Base team isolated the problem and restored the sequencer, bringing the network back online.

What actually broke

The invalid block sequence created a consensus failure, meaning the network couldn’t agree on the next valid state of the chain. The sequencer stalled, block production stopped, and users couldn’t get transactions processed.

This isn’t the first time Base has run into sequencer trouble. The network previously experienced a roughly 33-minute outage tied to a sequencer transition error, a similar class of failure that points to a recurring architectural vulnerability rather than a one-off fluke.

The OP Stack, the underlying framework Base is built on, uses a single sequencer by design. That design choice prioritizes speed and simplicity, but it creates a single point of failure.

Why centralization keeps coming up

Base launched in August 2023 as a permissioned Ethereum Layer-2 solution built on Optimism’s OP Stack. It grew quickly, becoming one of the largest Layer-2 networks by usage in a relatively short period.

Social media responses to the outage reflected user frustration, with users drawing unfavorable comparisons to Ethereum’s mainnet, which has maintained an uninterrupted block production record since the Merge. Ethereum mainnet benefits from thousands of independent validators, a luxury no current Layer-2 sequencer setup can claim.

What this means for investors and the broader Layer-2 landscape

The immediate market reaction was muted. ETH prices and Coinbase’s stock, ticker COIN, did not register a notable move in direct response to the outage. Major crypto outlets were slow to cover the event as it unfolded, which likely kept the market impact contained in the short term.

Base competes in a crowded field. Arbitrum, Optimism, zkSync, and Polygon are all vying for the same developer mindshare and user liquidity.

Optimism’s roadmap has included plans for a more decentralized sequencer model, and Base would inherit those improvements as a downstream OP Stack chain.
