Kaspa

Kaspa was launched by Yonatan Sompolinsky.

Kaspa was launched on November 7 2021, emerging from academic research into the GHOSTDAG protocol, which expands upon Bitcoin’s original structure to enable higher throughput.

Kaspa uses a consensus mechanism based on the BlockDAG protocol called GhostDAG,. This approach significantly increases throughput, supporting thousands of transactions per second. The DAG structure uses the order and relation of blocks rather than only a linear relation, solving limitations of scalability and speed in traditional Proof-of-Work blockchains.

Kaspa offers a range of compelling features and use cases:

• Speed: The BlockDAG architecture uses parallel block creation for fast, near-instant confirmations.
• Security: A robust model that uses decentralization.
• Affordability: Ultra-low fees make Kaspa ideal for high-frequency and micro-transactions.
• Scalability: Designed to handle high throughput, supporting thousands of transactions per second.
• Openness: Fully open-source with a strong, active community driving development and adoption.
• Futureproofing: Roadmap includes smart contracts, and DeFi support for broader utility.
