Financial systems process billions of time-series data points with sub-millisecond query requirements: constraints that break traditional databases.
Learn the architectural patterns that actually work: vertical scaling strategies, intelligent sharding schemes, and why market data demands different trade-offs than web applications.
Posted on Thu 23 October 2025 | Part 1 of DeFi Engineering
An introduction to the engineering landscape in DeFi protocols: the distinct engineering roles (protocol, infrastructure, execution), the complete technology stack from smart contracts to off-chain systems, core primitives like liquidity pools and oracles, and what makes building in this space fundamentally different from traditional fintech.
