Kaspa is a complicated system with many components, but at its core, it’s an implementation of the GHOSTDAG protocol, first conceptualized by Yonatan Sompolinsky and Aviv Zohar in 2016. The GHOSTDAG protocol allows for parallel block creation, which could potentially solve the scaling problem present in current blockchain technology.
The idea behind GHOSTDAG is that instead of having blocks point to a single parent, they can point to multiple parents, creating a DAG (directed acyclic graph) structure. This allows for more efficient block creation and faster confirmation times. However, there are challenges in implementing this protocol, such as determining the order of blocks and ensuring security against attackers.
Kaspa is currently in development and has not yet been stress-tested to see how many transactions it can handle. However, the team behind Kaspa believes that it has the potential to become the most resilient, robust, and fast PoW (proof of work) blockchain in the world.
