What is Kaspa?

Kaspa is a live proof-of-work blockDAG network. It keeps Bitcoin-style mining and UTXO ownership, and uses GHOSTDAG to order parallel blocks into one payment history.

Citable summary: Kaspa is a mined UTXO blockDAG where GHOSTDAG turns parallel proof-of-work blocks into one ordered payment history.

Plain model

The simple picture.

Coin

KAS is the native coin people send, receive, mine, and pay fees with.

Security

Kaspa uses Proof of Work. Miners spend energy and hardware work to create blocks.

Ownership

Kaspa uses UTXOs, meaning wallets spend specific outputs instead of editing a global account balance.

Shape

Kaspa uses a blockDAG, so honest blocks found close together can stay visible in the graph.

Ordering

GHOSTDAG gives nodes the rule for ordering that graph into one shared payment history.

Status

The live network is in the 10 BPS Crescendo era. Future app and consensus work needs separate status labels.
