High-throughput services spend much of their time waiting on I/O. Go's runtime addresses this by multiplexing large numbers of lightweight tasks through goroutines, an internal scheduler, and coordinated synchronization primitives.

Small trading systems optimize code paths. Larger ones optimize data movement. Scaling beyond Pandas means treating storage layout, ingestion, and derived datasets as part of the backtesting engine.

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.
