Widespread internet outages tied to major infrastructure providers reignited a long-running debate in 2025: how decentralized is crypto really if so much of it still depends on centralized web services.
Following disruptions linked to both Cloudflare and Amazon Web Services, Ethereum co-founder Vitalik Buterin argues that decentralized applications may offer a path forward.
The outages, which briefly knocked major crypto platforms offline, highlighted a structural contradiction within the industry. While blockchains themselves may be decentralized, access to them often depends on centralized cloud providers and content delivery networks.
During the November Cloudflare incident, roughly 20% of websites using the service were temporarily affected after a software failure caused a bot-management configuration file to exceed its limits. Crypto platforms including Coinbase, Blockchain.com, BitMEX, and Ledger experienced downtime, echoing similar disruptions seen during an Amazon Web Services outage in October.
The back-to-back failures raised renewed concerns about reliability, resilience, and single points of failure across the crypto ecosystem.
In response, Buterin said Ethereum’s ambition to become a “world computer” depends on applications that can operate independently of centralized intermediaries. In a post on X, he argued that users should not even notice when services like Cloudflare go offline — or are compromised — because applications should continue functioning without interruption.
According to Buterin, resilient decentralized applications must run without fraud, censorship, or third-party interference, while also protecting user privacy and operating at scale. He framed this not only as a financial issue, but as a requirement for broader digital infrastructure, including identity systems, governance tools, and other foundational services.
These ideas echo a manifesto released in November by Buterin alongside Ethereum Foundation researchers Yoav Weiss and Marissa Posner, which warned that decentralization often erodes through convenience rather than direct capture. Systems, they argued, naturally drift toward trusted intermediaries when ease of use outweighs long-term resilience.
Beyond infrastructure resilience, Buterin has continued to explore improvements at the protocol level. In early December, he proposed the idea of a trustless onchain gas futures market, aimed at giving users greater certainty over transaction fees and reducing reliance on external assumptions.
As crypto moves into 2026, the lesson from 2025’s outages is clear: decentralization cannot stop at the blockchain layer. Until applications themselves are built to withstand failures in the traditional internet stack, even the most decentralized networks remain vulnerable to centralized points of failure.
