Ethereum Secures $74 Billion Yet a Single Web2 Switch Can Still Cut Your Access in Minutes

Why Even the Most Valuable Blockchain Still Relies on Fragile Internet Infrastructure

In late 2025 the Ethereum network remained one of the most valuable and widely used blockchains in the world with more than $74 billion worth of digital assets secured by its consensus and smart contract ecosystem. Despite this massive economic footprint and the deep technical resilience built into its decentralized design the reality for everyday users and developers is that access to that network often still depends on Web2 infrastructure such as centralized service providers API gateways and internet connectivity that can break or be switched off at any time.

Ethereum’s core protocol the ledger and consensus mechanisms that ensure transactions are valid and assets are safe does not depend on any single company or server. The value locked in smart contracts and the millions of ETH staked as part of Ethereum’s proof of stake validation are protected by cryptographic security and thousands of independent nodes around the world that verify and propagate data. This on-chain security model is the reason Ethereum can sustain such a high valuation and broad usage across decentralized finance applications NFTs and global payments.

Yet for most users interacting with Ethereum applications today the experience begins long before a block is mined. People access wallets and decentralized applications using Web2 interfaces such as web browsers mobile apps and centralized API providers that connect them to the blockchain. Services like Infura Alchemy and other node as a service platforms host the infrastructure that relays user transactions to the Ethereum network and returns data for applications. If these services experience outages are blocked in certain regions or are hit by censorship events users can find themselves unable to see balances send transactions or interact with smart contracts even though the underlying blockchain continues to operate.

This dependency on Web2 points to a core tension in the architecture of Ethereum and many other blockchains: while the settlement layer and consensus are decentralized on chain the user experience layer remains heavily centralized. Centralization at this layer can include corporate-run web interfaces custodial wallets or API services that act as bridges between users and the decentralized protocol. When these centralized pieces fail users can be effectively cut off from the network they rely on for finance and digital ownership.

Historical examples have shown how fragile this bridge can be. In April 2022 a major outage at Infura one of the largest Ethereum API providers caused wallets and decentralized applications that depend on their service to stop working for many users until services were restored. Although the Ethereum blockchain itself was unaffected the user experience and access to decentralized services ground to a halt because of the Web2 dependency.
