What is KAS ? - Kaspa Explaied
kas is the project’s native currency, and is used for all on-chain transactions and to distribute mining rewards. kas is not a token - it is a Layer-1, hence references to kas as a ‘coin’.
kaspa (or kas) is a blockchain platform that aims to address some of the scalability and interoperability challenges faced by existing blockchain networks. kaspa is built on a unique data structure called the GHOSTDAG (Greedy Heaviest Observed Sub-Tree Directed Acyclic Graph), which allows for fast and efficient block propagation and confirmation.
Imagine you have a big tree with lots of branches and leaves. Each branch represents a different transaction that has been made on a blockchain network.
Now, imagine you want to add a new transaction to this tree. The problem is, you need to make sure that the new transaction is connected to the existing transactions in a way that makes sense.
The Greedy Heaviest Observed Sub-Tree Directed Acyclic Graph (or GHOSTDAG for short) is a special way of organizing this tree so that new transactions can be added quickly and efficiently. Instead of adding the new transaction to the end of the tree like a regular blockchain, GHOSTDAG looks for the heaviest part of the tree that includes the new transaction, and then adds the transaction to that part of the tree.
This makes the process of adding new transactions much faster and more efficient than traditional blockchain structures. It also allows for parallel processing of transactions, which means that multiple transactions can be processed at the same time, further increasing the speed of the network.
The GHOSTDAG data structure allows for a high degree of parallelization, which means that blocks can be processed in parallel rather than in a linear sequence. This allows for faster confirmation times and a higher transaction throughput compared to other blockchain networks. The GHOSTDAG structure also allows for sharding, which is a technique for dividing a blockchain network into smaller, more manageable parts. This can improve the scalability of the network by allowing more transactions to be processed in parallel.
kaspa uses a Proof of Work (PoW) consensus mechanism, similar to Bitcoin. However, it uses a modified version of the PoW algorithm that is optimized for the GHOSTDAG data structure. This allows for a more efficient use of computational resources, which can help to reduce the environmental impact of mining and make the network more accessible to a wider range of users.
