Infura as DeFi infrastructure backbone
Consensys
Infura’s importance comes from turning Ethereum node operations into a utility, which let DeFi apps scale fast but also created a hidden central point of failure. Instead of each team running its own full node, handling chain upgrades, and keeping data in sync, developers could plug into Infura’s APIs and ship. That convenience made Infura the default backend for wallets, exchanges, NFT apps, and DeFi protocols across Ethereum.

The clearest proof was the November 11, 2020 outage. Infura said its mainnet service suffered its most severe interruption in four years, and the Consensys company page notes Binance and Bithumb paused Ethereum withdrawals during the incident. That is what core infrastructure looks like in practice, when one backend problem ripples into customer-facing products across crypto.

What Infura actually sells is outsourced node management. A competing infrastructure founder describes the job plainly, teams need a provider to keep blockchain clients synced, handle hard forks and upgrades, cache and index chain data, and expose it through JSON-RPC APIs. That removes the need for every DeFi startup to hire DevOps engineers before it can even read balances or send transactions.

The competitive pattern looks a lot like cloud infrastructure. Consensys frames Infura as an AWS for crypto product, and Alchemy was funded at a $10.2B valuation in February 2022 on the same thesis, that reliable blockchain APIs are the picks and shovels layer for Web3. The difference is that Infura went deep on Ethereum early, which helped it become embedded before the market got crowded.
Going forward, this layer gets more valuable as wallets, exchanges, and apps spread across more chains and more institutional use cases. The winners will be the providers that move beyond raw node access into higher value APIs, transaction routing, indexing, and reliability tooling, while reducing the concentration risk that early Ethereum infrastructure exposed.
