Kaspa is a blockchain platform designed to provide a scalable and decentralized infrastructure for applications requiring high transaction throughput.
Kaspa (KASPA) distinguishes itself in the cryptocurrency space with its proof-of-work (PoW) consensus mechanism and innovative use of the GHOSTDAG protocol. Unlike traditional blockchain structures, Kaspa utilizes a blockDAG (Directed Acyclic Graph), specifically implementing GHOSTDAG to handle concurrent block creation without orphaning. This approach allows blocks to coexist and be ordered through consensus, promoting a highly scalable and efficient blockchain network.
One of Kaspa's notable strengths lies in its ability to achieve exceptionally high block rates, currently processing one block per second with aspirations to reach 10 blocks per second and ambitions for 100 blocks per second in the future. This rapid block generation results in minuscule confirmation times, largely governed by internet latency rather than traditional blockchain consensus constraints.
The Kaspa implementation includes several advanced features designed to enhance its functionality and scalability. These features encompass Reachability for querying the DAG's topology, Block data pruning capabilities (with future plans for block header pruning), SPV (Simplified Payment Verification) proofs, and upcoming subnetwork support. These innovations not only bolster the security and efficiency of the Kaspa blockchain but also pave the way for seamless integration of layer 2 solutions in the future.
