What is Kaspa & How it Works


Kaspa is unique and a step ahead of other traditional cryptocurrencies by solving the trilemma faced by traditional cryptocurrencies — security, scalability, and decentralization. Kaspa achieves that by utilizing a revolutionary blockDAG, unlike blockchain.

Since Kaspa enables the fastest, most scalable, most secure, and most decentralized transactions, Kaspa has the potential to revolutionize the blockchain space. Let’s uncover more about Kaspa, its characteristics, and how it works in detail with this blog.


    What is Kaspa?

    Kaspa is the fastest, most scalable, open source, decentralized, and instant confirmation transaction layer backed by a Proof-of-Work (PoW) consensus mechanism. Kaspa incorporates blockDAG (Block Directed Acyclic Graph) architecture, which is a digital ledger allowing parallel blocks and instant transaction confirmation.

    Kaspa is known for its fastest transactions. The revolutionary blockDAG architecture of Kaspa facilitates transactions to be added to the distributed ledger immediately. Moreover, Kaspa follows the GhostDAG/PHANTOM protocol, which abides by the principles of the Satoshi Nakamoto Consensus, followed by Bitcoin. Thus, Kaspa has all the benefits of Bitcoin, such as being deflationary, decentralized, and having no premine.

    In short, Kaspa transactions are faster than traditional crypto transactions like Bitcoin, like one block per second, but are as secure as Bitcoin transactions due to the PoW mechanism. Moreover, Kaspa is currently undergoing a language rewrite to increase the number of blocks per second. That, in turn, will attract the development of smart contracts and DeFi (Decentralized Finance).

    How does Kaspa Work?

    How does Kaspa Work

    Unlike traditional blockchains, Kaspa utilizes a revolutionary blockDAG architecture, facilitating the fastest, most scalable, secure, and decentralized transactions. Let’s see how Kaspa works and how the blockDAG architecture makes Kaspa unique from other traditional cryptocurrencies in detail.

    • Fastest Transactions

    Kaspa transactions are relatively faster than traditional cryptocurrencies like Bitcoin and Ethereum. For instance, conventional blockchains are limited in speed due to their ineffective design. Kaspa’s blockDAG architecture supports fast, subsecond confirmations, which means immediate transaction confirmations.

    • Instant Confirmations

    Crypto transactions are stored in a block on a blockchain. A network of nodes validates these transactions by analyzing the sender and receiver’s credentials. Conventional blockchains have slow confirmation times. Kapsa ensures transactions in one second, removing the confirmation bottleneck. The confirmation time is expected to decrease further after the rust update.

    • Better Scalability

    Scalability has always been a question mark with cryptocurrencies. The system may get clogged or slowed down if many users transact simultaneously. The blockDAG architecture of Kaspa manages significant amounts of transactions simultaneously at an average rate of one block per second. Thus, Kaspa can handle numerous transactions in less time.

    • Decentralization

    Kaspa follows the PoW-based consensus algorithm, KHeavyhash, which is highly efficient and supports decentralization. The KHeavyhash algorithm allows high hashing power per watt compared to other PoW algorithms like SHA-256, ETHash, etc. Moreover, Kaspa is more secure and energy-efficient than other PoW blockchains.

    • Enhanced Security

    Kaspa follows the KHeavyhash algorithm, which inherits all the security features of SHA-256. Thus, the blockDAG is secured by a decentralized network of nodes like Bitcoin. Miners worldwide validate and secure the network without any central governance.

    • BlockDAG Architecture

    Kapsa leverages the blockDAG architecture, where transactions are recorded in blocks, which are ordered by time and sealed. The architecture represents blocks and edges, referring to child/parent blocks that facilitate scalability, high throughput, instant confirmations, and decentralization.

    How does Kaspa Solve the Trilemma Issues?

    Traditional cryptocurrencies like Bitcoin and Ethereum suffer from three significant problems — security, scalability, and decentralization. Kaspa solves these trilemma issues effectively by leveraging blockDAG architecture and GhostDAG protocol.

    Before moving on to Kaspa, let’s look at the trilemma issues cryptocurrencies encounter. Conventional cryptocurrencies should limit their block creation time to limit orphans. A high orphan rate decreases the defense of the network, compromising security. Kaspa solves this by using the GhostDAG protocol that incorporates Nakamato’s chain into a directed acyclic graph of blocks called blockDAG.

    GhostDAG protocol enables Kaspa to outdo traditional cryptocurrencies by improving the block rate and enhancing security. That, in turn, improves Kaspa by 51% in security and throughput on the order of one block per second.

    Here is how Kaspa overcomes the trilemma issues faced by existing cryptocurrencies.

    1. Fastest Confirmations

    Traditional cryptocurrencies have slow block rates and, thereby, slow confirmations. Since Kaspa’s consensus layer enables fast and immediate confirmations, the Kaspa transactions are more rapid. That makes Kaspa ideal for applications that demand quick proof of publication.

    2. High Throughput

    Conventional cryptocurrencies suffer low transaction throughput due to their slow block rates. With GhostDAG protocol, Kaspa’s consensus layer enhances high throughput by increasing block rate and block size. Besides, Kaspa optimizes bandwidth cost and network infrastructure for optimal throughput.

    3. Mining Decentralization

    Existing cryptocurrencies have slow block rates, paving the way for uneven distribution of mining profitability. In simple words, irregular mining rewards are due to difficulty in finding the block. Thus, miners will join larger mining pools to combine significant computing power.

    However, with more miners joining the network, the mining difficulty increases, centralizing the consensus power to the hands of a few authorized persons like mining pool managers. Kaspa’s consensus layer aids fast block rates and evenly distributes the mining income, decreasing the incentive to join mining pools while contributing to mining decentralization.
