Kaspa ASICs

O KASPA

Its design is true to the principles that Satoshi incorporated into Bitcoin – proof-of-work mining, an isolated state created by UTXO, a deflationary monetary policy, no pre-mining and no central control. Kaspa is unique in its ability to support a high frequency of blocks without affecting the level of security offered by the most secure proof-of-work environments. The current main network Kaspa it works with one block per second. Following the ongoing Rust rewrite, the core developers aim to significantly increase the number of blocks per second, making it attractive for smart contract and DeFi (decentralized finance) development.

SOLUTION OF THE TRILEMMA

Traditional cryptocurrencies suffer from a trade-off between security, scalability, and decentralization: decentralized cryptocurrencies must limit the rate at which blocks are created to reduce the number of "orphans," which are blocks created off-chain during the time a block is propagating through the network. A high number of orphans reduces the effectiveness of the PoW (Proof of Work) network and thus weakens its defense against attacks by malicious participants. It uses a consensus layer to resolve this trade-off Kaspa the GhostDAG protocol, which is a Proof of Work (Proof of Work) consensus protocol that generalizes the Nakamoto chain to a directed acyclic block graph (blockDAG). GhostDAG incorporates "orphaned" blocks into the chain by creating a blockDAG, and then uses a new hungry algorithm to organize blocks by favoring well-connected, honest blocks, quickly and with high probability. GhostDAG enables Kaspa bypass traditional blockchain trade-offs, increase the speed of block creation by several orders of magnitude and maintain theoretical Bitcoin-level security.

The result is a cryptocurrency that is backed by 51% security, has a large number of miners/nodes, and achieves throughput of the order of one block per second. This differs from existing cryptocurrencies, which inevitably sacrifice a small number of validating nodes or a lower security BFT (the 33% threshold required for attacks by malicious participants on the network).

Quick confirmations

The slow block creation rate of traditional cryptocurrencies means slow confirmations, i.e. the time it takes for a transaction to be published on the blockchain. Consensus layer Kaspa ASICs supports fast confirmations in the order of seconds - fast first confirmation, which allows use in cases where immediate proof of publication (but not immediate irreversibility) is needed, such as e-commerce.

High throughput

The slow block creation speed of traditional cryptocurrencies also means low transaction throughput. Using GhostDAG removes the consensus layer Kaspa security as a bottleneck for high throughput, allowing the speed and block size to increase to a level that the network can handle. Kaspa it also optimizes data transmission costs and network infrastructure for high throughput.

Decentralization of mining

The slow block creation rate of traditional cryptocurrencies also means high variability in mining income (ie irregular mining rewards due to the difficulty of finding a block), which incentivizes miners to join larger and larger mining pools – which combine computing power and distribute smaller, more regular rewards participants – as the network grows and block difficulty increases. This centralizes the power of the consensus in the hands of a few mining pool managers. Fast speed of creating blocks in the consensus layer Kaspa it reduces the variability of mining income, which reduces the incentive to join mining groups, and contributes to the decentralization of mining.
