How Blockchain Transactions Settle

Mempools, confirmations, finality and fees, explained end to end.

From broadcast to block

A signed transaction enters a public waiting area, is selected by a block producer based on fee, and is then included in a block that propagates across the network.

Probabilistic versus absolute finality

Proof of work finality strengthens with each confirmation. Some proof of stake systems provide explicit finality after a defined checkpoint.

Fee behaviour

Fees are an auction for limited block space. Fee spikes are a demand signal, not a malfunction.

Key takeaways

• Probabilistic versus absolute finality: Proof of work finality strengthens with each confirmation.
• Fee behaviour: Fees are an auction for limited block space.
