If blocks arrive quickly, honest miners can find blocks at nearly the same time.
Protocol explainer
GHOSTDAG explained
GHOSTDAG is the live Kaspa rule that turns a graph of parallel proof-of-work blocks into one ordered payment history.
Summary: GHOSTDAG is Kaspa's current blockDAG ordering rule; it is not DAGKnight and it does not mean instant finality.
Plain model
Why Kaspa needs it
A single chain has to choose one path. Some honest work can become stale or orphaned.
A blockDAG keeps more parallel blocks visible in the record.
GHOSTDAG gives nodes a shared way to classify and order the graph.
Transactions can appear quickly while confirmation confidence increases over time.
Fast mined ordering increases confirmation speed. Irreversibility still depends on confirmation depth and risk tolerance.
Confusions
Say it safely
| Question | Answer | Best wording |
|---|---|---|
| Is GHOSTDAG live? | Live | GHOSTDAG is Kaspa's live blockDAG ordering rule. |
| Is it DAGKnight? | No | DAGKnight is a separate future consensus direction. |
| Does it remove finality risk? | No | Kaspa has fast inclusion and probabilistic confirmation confidence. |
| Does it mean unlimited TPS? | No | Throughput depends on block capacity, policy, fees, demand, and network conditions. |
