Real-Time Decentralization.
Built for Real-World Settlement.
Kaspa is the fastest, open-source, decentralized, and fully scalable Layer 1 in the world.
It is the first blockDAG, a digital ledger that enables parallel block creation and instant transaction confirmation. It runs on a robust proof-of-work engine, designed to handle up to 10 blocks per second without compromising security or decentralization.
Built by industry pioneers, led by the people.

TECHNICALLY SPEAKING
Kaspa is a proof-of-work cryptocurrency which implements the GHOSTDAG protocol. Unlike traditional blockchains, GHOSTDAG does not orphan blocks created in parallel, but rather allows them to coexist and orders them in consensus. Whereby Kaspa is actually a blockDAG; you can see GHOSTDAG in action in a real time blockDAG visualizer.
This generalization of Nakamoto consensus allows for secure operation while maintaining very high block rates (currently 10 blocks per second, aiming for 32/sec, with visions of 100/sec) and minuscule confirmation times dominated by internet latency (cf. chapter 6 of the research paper for some initial benchmarks).
The Kaspa implementation includes a lot of cool features and subprotocols including Reachability to query the DAG’s topology, Block pruning (with near-future plans for block header pruning), SPV proofs, and later subnetwork support which will make future implementation of layer 2 solutions much easier.

Fastest Transactions
Kaspa’s blockDAG network generates multiple blocks every second for posting transactions to the ledger. Combined with fully confirmed transactions in 10 seconds, this makes Kaspa ideal for everyday transactions.
Instant Confirmation
Kaspa was designed to be hundreds of times faster than Bitcoin, with each Kaspa transaction visible to the network in one second, and each transaction fully confirmed in 10 seconds on average.
Scalability
Kaspa solves the scalability problem with its ability to generate and confirm multiple blocks per second. This comes with no trade-off to security and decentralization as seen with Proof-of-Stake networks.
Efficient Proof-of-Work
Kaspa utilizes the optical-mining ready kHeavyHash algorithm for consensus and security of the network. This algorithm, combined with high-throughput DAG and no-wasted-blocks, makes it less energy intensive than other PoW networks.
Security
Kaspa harnesses an ultra secure block network with no compromise to decentralization. Achieved with pure, stake-less, proof-of-work combined with a revolutionary GhostDAG Consensus mechanism.
BlockDAG
Overcoming the problem of blockchains, Kaspa processes all blocks in parallel linking all side-chains. This leads to a DAG structure that increases the formation of blocks per second drastically, creating a blockDAG.
