    "excerpt": "From one node to Cortex: serving blockchain data at 100K TPS, globally.\n\nWhat does it take to serve blockchain data at the lowest possible latency at 100K+ TPS - reliably, globally, and with perfect consistency?\n\nThat was the challenge Alchemy faced in early 2023 as Alchemy mapped out how to support the next wave of scaled blockchain apps, especially the ones onboarding millions of new users, like World App and Robinhood.\n\nIts journey started in 2017 with a single Ethereum node. Since then, Alchemy has powered countless applications through bull markets, bear markets, and everything in between. All of that operational experience led to Cortex, the world's first intelligent blockchain engine.\n\nToday, Cortex powers its entire developer platform: RPC APIs, Data APIs, Gasless Transactions and Rollups. It's a major leap forward for every Alchemy product. No migrations, no new tools to learn. Just smarter, faster infrastructure built on years of real-world lessons.\n\nThe road to Cortex.\n\nIn the early days, its founders Nikil and Joe were building a blockchain research tool for hedge funds when they ran into the pain of running Ethereum nodes themselves. A single node worked until demand exploded during the 2017 ICO boom. Scaling horizontally helped with throughput, but it introduced a huge challenge: data consistency - ensuring every user saw the same canonical blockchain state...",
