What it shows

  • Senders face strict balance checks and temporary hold reservations.
  • Double-entry ledgers update sender and receiver balances atomically.
  • Push notifications fire only after transaction commit acknowledgement.

The takeaway

Atomic two-phase commits prevent ledger desync in peer-to-peer transfers.
