How does Kaspa achieve instant transaction confirmation?

Kaspa achieves instant confirmation by letting transactions enter the ledger as soon as a miner picks them up, without waiting in a queue. Traditional blockchains process one block at a time in a strict sequence, so a transaction must wait for the next block slot to open. Kaspa's ledger is structured as a blockDAG — a directed acyclic graph — which supports asynchronous state updates, meaning multiple blocks can be processed in parallel rather than one after another. For a beginner, this means your Kaspa transaction can reach the ledger almost immediately after submission, rather than sitting in a mempool through multiple confirmation delays.
