Kaspa (KAS) is a proof-of-work cryptocurrency that represents one of the most significant technical innovations in blockchain scaling since Bitcoin. Launched in 2021, Kaspa implements a blockDAG (Directed Acyclic Graph) architecture — replacing the traditional single-chain structure with a parallel block structure where multiple blocks can be created simultaneously and all are included (rather than orphaned), dramatically increasing throughput without sacrificing security or decentralisation. This is achieved through the GHOSTDAG protocol, which orders parallel blocks into a consensus chain.
Kaspa’s technical achievements: 10 blocks per second target (moving toward 100 BPS), vs Bitcoin’s 1 block per 10 minutes; Near-instant confirmation — transactions are visible to the network in under 1 second; True PoW decentralisation — Kaspa uses kHeavyHash, an ASIC-resistant algorithm originally, now transitioning to support ASICs while maintaining decentralisation; No pre-mine, no ICO — fair launch in the spirit of Bitcoin; and Deflationary emission — block rewards halve smoothly on a monthly basis (a “chromatic halvening”). Kaspa has attracted significant attention from the Bitcoin community as a potential successor architecture that preserves PoW values while solving scalability. Its rapid rise from obscurity to a top-30 asset reflects genuine technical credibility.
Example: A developer stress-tests Kaspa by broadcasting 10 transactions simultaneously. All 10 are included in parallel blocks within 1 second — demonstrating blockDAG’s ability to handle concurrent transactions that would create orphaned blocks on Bitcoin.
