  MultiPaxos, while a fundamental Replicated State Machine algorithm, suffers
from a dearth of comprehensive guidelines for achieving a complete and correct
implementation. This deficiency has hindered MultiPaxos' practical utility and
adoption and has resulted in flawed claims about its capabilities. Our paper
aims to bridge the gap between MultiPaxos' complexity and practical
implementation through a meticulous and detailed design process spanning more
than a year. It carefully dissects each phase of MultiPaxos and offers detailed
step-by-step pseudocode -- in addition to a complete open-source implementation
-- for all components, including the leader election, the failure detector, and
the commit phase.
  The implementation of our complete design also provides better performance
stability, resource usage, and network partition tolerance than naive
MultiPaxos versions. Our specification includes a lightweight log compaction
approach that avoids taking repeated snapshots, significantly improving
resource usage and performance stability. Our failure detector, integrated into
the commit phase of the algorithm, uses variable and adaptive heartbeat
intervals to settle on a better leader under partial connectivity and network
partitions, improving liveness under such conditions.
