What is Kaspa KAS max TPS?

Kaspa, a cutting-edge Proof-of-Work (PoW) blockchain, has demonstrated remarkable throughput and efficiency in its mainnet performance. The network has been running consistently at 1 Block Per Second (BPS) for over two years, showcasing robust performance with thousands of nodes participating. Recent internal tests of the new 10 BPS code indicate that Kaspa has the potential to significantly increase its throughput, with a public test already achieving 3,000 Transactions Per Second (TPS) smoothly over a three-day period.

Unpacking Kaspa’s Scalability Potential

The Kaspa team is actively exploring the relationship between BPS, block size, and TPS to optimize scalability. Preliminary findings suggest that the network could support up to 10,000 TPS using affordable hardware costing around $100. This level of scalability is particularly impressive considering Kaspa’s ability to maintain low confirmation times and high security standards. Unlike networks like Conflux, which require approximately 50 seconds for a first confirmation, Kaspa delivers near-instant confirmations with security comparable to Bitcoin within just 10 seconds.

How Kaspa Achieves Scalability Without Overburdening Nodes

A common concern in scaling high-throughput blockchains is the increased resource demand on nodes. Kaspa, however, has proven to handle increased transaction loads efficiently. During high-throughput tests, nodes operating on modest, older hardware managed the load effortlessly, without crashes or significant strain. This efficient handling is attributed to Kaspa’s innovative fee strategy, which optimizes miner behavior to maximize profits while avoiding bottlenecks.

Security and Finality: Addressing Probabilistic Concerns

Kaspa employs a probabilistic finality model, where transaction security increases exponentially with each confirmation. At a rate of 10 BPS, the probability of an attacker successfully reversing a transaction drops to negligible levels within seconds. For instance, against a hypothetical 45% attacker, the likelihood of a double-spend attempt succeeding becomes smaller than the chance of brute-forcing an ECDSA key in under an hour after just 30 seconds of confirmations.

A Benchmark in PoW Blockchain Evolution

The achievements of the Kaspa mainnet mark a milestone in PoW blockchain history. The network has demonstrated the ability to sustain organic throughput of 250-300 transactions per second (BPS-level) while maintaining high security and efficiency. This performance establishes Kaspa as a leader in scalable, decentralized blockchain systems, redefining what’s possible with Proof-of-Work technology.

In summary, while Kaspa’s maximum TPS is still being refined, its potential to reach 10,000 TPS on affordable hardware solidifies its place as a pioneering force in blockchain scalability and security.
