Here is the precise sequence of events: **Step 1: Coordinator Initiates Prepare** When the application requests to commit the distributed transaction, the coordinator: 1. Writes a `` record to its local stable log 2. Sends a `PREPARE` message to all participants 3. Sets a timeout timer for collecting votes **Step 2: Participant Processes PREPARE** Upon receiving the PREPARE message, each participant decides whether it can commit. **If the participant CAN commit:** 1. It writes a `` record to its stable log 2. It replies with `VOTE_COMMIT` 3. It enters the **prepared state** (also called the **uncertain state**) 4. It releases no locks—resources remain locked! **If the participant CANNOT commit** (constraint violation, deadlock, resource unavailable): 1. It writes an `` record to its stable log 2. It replies with `VOTE_ABORT` 3. It aborts its local portion and releases locks 4.

Each server independently manages its local data and has no direct knowledge of the others' states. If the New York server commits the debit but the London server fails before crediting, the system enters an **inconsistent state** where money has vanished.

For atomicity, we require:\n\n1. **All-or-Nothing Execution**: Either every participant commits the transaction, or none of them do\n2. **Unanimous Agreement**: If any participant cannot commit (due to constraint violations, deadlocks, or failures), then no participant commits\n3. **Irrevocability**: Once a participant commits, it cannot later abort (and vice versa)\n4. **Eventual Termination**: The protocol must eventually reach a decision, not remain indefinitely uncertain\n\nThese requirements seem intuitive, but achieving them in the presence of **unreliable networks** and **node failures** is remarkably subtle."},"type":"text"},{"data":{"icon":"AlertCircle","title":"The Impossibility Result","content":"The Fischer-Lynch-Paterson (FLP) theorem proves that no deterministic protocol can guarantee consensus in an asynchronous system with even one faulty process.
