Kaspa Introduction
Kaspa is a next-generation blockchain protocol designed to overcome the scalability limitations of traditional blockchains. It introduces PHANTOM and GHOSTDAG, which transform the linear blockchain into a directed acyclic graph of blocks (blockDAG). This structure allows for higher throughput and faster confirmation times while maintaining security and decentralization. Kaspa aims to provide a scalable and efficient platform for decentralized applications and financial transactions.

Description: What Does Kaspa Do?
Kaspa is designed to address the scalability issues inherent in traditional blockchain protocols. By introducing the PHANTOM and GHOSTDAG protocols, Kaspa transforms the linear blockchain into a directed acyclic graph of blocks (blockDAG). This innovative approach allows for higher throughput and faster confirmation times while maintaining security and decentralization.
PHANTOM is a proof-of-work-based protocol that includes a parameter (k) to control tolerance for concurrently created blocks. GHOSTDAG, an efficient greedy algorithm derived from PHANTOM, captures its essence and has been implemented as the underlying technology of the Kaspa cryptocurrency. Kaspa provides real-world statistics on GHOSTDAG's performance, including confirmation times and security proofs.
Problem: Why Kaspa Is Being Developed?
The primary problem Kaspa aims to solve is the scalability limitation of traditional blockchain protocols, such as Bitcoin. The security of Bitcoin's longest chain rule requires that all honest nodes be aware of each other's blocks very soon after their creation, which suppresses throughput to ensure block propagation before the next block is created. This results in a highly limited scalability.
Current solutions, like Bitcoin, face a tradeoff between security and scalability. PHANTOM and GHOSTDAG address this issue by allowing for higher throughput and faster confirmation times without compromising security. By generalizing the blockchain into a blockDAG structure, Kaspa overcomes the limitations of traditional blockchains.
Use Cases
- Decentralized Finance (DeFi): Kaspa can support high-throughput financial applications, enabling faster and more efficient transactions.
- Decentralized Applications (dApps): The scalable blockDAG structure allows for the development of complex dApps with high transaction volumes.
- Cross-border Payments: Kaspa's fast confirmation times make it ideal for international remittances and cross-border transactions.
How Does Kaspa Work?
Kaspa consists of the PHANTOM and GHOSTDAG protocols, which transform the linear blockchain into a blockDAG structure.
-
Components:
- PHANTOM: A proof-of-work-based protocol that generalizes the blockchain into a blockDAG.
- GHOSTDAG: An efficient greedy algorithm derived from PHANTOM, implemented as the underlying technology of Kaspa.
-
Operation:
- Step 1: Nodes (miners) create blocks containing transactions.
- Step 2: Blocks are added to the blockDAG, rather than a linear chain.
- Step 3: The PHANTOM protocol distinguishes between blocks mined by honest nodes and those created by deviating nodes.
- Step 4: GHOSTDAG orders the blocks in the blockDAG in a way that is eventually agreed upon by all honest nodes.
- Step 5: Transactions are confirmed based on the ordered blocks in the blockDAG, ensuring fast confirmation times and high throughput.
Technical Details
Kaspa utilizes a blockDAG structure to enhance scalability and throughput. The PHANTOM protocol generalizes the blockchain into a directed acyclic graph of blocks, allowing for higher throughput by tolerating concurrently created blocks. GHOSTDAG, derived from PHANTOM, captures its essence and provides an efficient ordering of blocks.
