What it shows

Quorum consensus: Acquire locks across 3 of 5 independent Redis masters.
Validity window: Subtract clock drift and elapsed network time from TTL.
Release safety: Verify random token ownership with atomic Lua scripts.

The takeaway

Redlock guarantees mutual exclusion across independent nodes even if single instances fail abruptly.
