Blockchains are often explained through protocol-specific concepts like blocks or slots. This article reframes them as distributed state-transition systems, where ambiguity and delayed agreement exist to varying degrees across chains.

Modern trading systems rely on directed acyclic graphs (DAGs) that branch, merge, and transform real-time feeds into many parallel consumers: matching engines, risk checks, analytics, surveillance, and storage. These ingestion DAGs exist to isolate failure, control fan-out, and preserve latency and correctness under extreme market conditions.

Low-latency systems fail when work becomes unbounded. Batching, conflation, and backpressure are mechanisms that keep systems stable under bursty, adversarial load. Without them, tail latency and cascading failures are inevitable.

Every microsecond counts, but where do they actually go?
This article traces the hidden journey of a message from the network wire to the application's code, revealing how the NIC, interrupts, syscalls, and runtimes introduce delay at every hop.

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.
