Kaspa (KAS)

A proof-of-work BlockDAG network launched in November 2021 without pre-mine or pre-sale, implementing the GHOSTDAG consensus protocol for near-instant confirmation times limited by network latency rather than consensus mechanics.

What is Kaspa?

A community-managed proof-of-work network implementing the GHOSTDAG BlockDAG consensus protocol , achieving confirmation times bounded only by network latency, designed to integrate hard money principles with scalability and smart contract support via rollups.

Bitcoin is the first decentralized cryptocurrency, created in 2009 by an individual or group using the pseudonym Satoshi Nakamoto. It operates as a peer-to-peer electronic payment system that enables direct transactions between users without intermediaries such as banks or payment processors.

Bitcoin transactions are secured using the SHA-256 cryptographic algorithm and recorded on a distributed public ledger called a blockchain, maintained across thousands of computers worldwide. New blocks are added approximately every 10 minutes.

Fair Launch , No Pre-Mine or Pre-Sale

Kaspa launched in November 2021 without a pre-mine, pre-sale, or pre-allocated coin distribution, and operates as a community-managed network. This launch model aligns with the fair distribution principles of early proof-of-work cryptocurrencies.

GHOSTDAG , BlockDAG Consensus

Kaspa implements GHOSTDAG, a consensus protocol that combines proof-of-work with a directed acyclic graph (DAG) structure rather than a linear chain. This allows multiple blocks to be created simultaneously and included in the DAG without being discarded as orphans.

Latency-Bounded Confirmation Times

The protocol achieves confirmation times limited primarily by network latency rather than consensus mechanics. Unlike traditional proof-of-work chains where block time is a security parameter, Kaspa's architecture decouples block frequency from security, enabling rapid confirmation.

50% Security Threshold

Kaspa targets a 50 percent security threshold supported by distributed mining , meaning the network remains secure as long as no single entity controls more than half of the hash rate, consistent with the standard Byzantine fault tolerance model for proof-of-work.

Five Network Characteristics

The Kaspa network integrates five design goals: hard money principles aligned with Bitcoin's security-first approach, a 50% security threshold, decentralization through rapid block generation, faster confirmation times than competing PoW and PoS networks, and smart contract support via rollup-based solutions.

Scalability Infrastructure

Technical features supporting scalability include Reachability for querying DAG topology, block data pruning mechanisms, simplified payment verification (SPV) proofs, and planned subnetwork support , components designed to facilitate future layer-two solutions and reduce on-chain data requirements.

Ecosystem & Development

Kaspa's GHOSTDAG architecture is designed to serve as a sequencer for both traditional finance and decentralized cryptocurrency markets, with planned rollup-based smart contract support extending its capabilities beyond base-layer transactions.

TradFi & DeFi Sequencer

Kaspa is designed to function as a sequencer for both traditional finance and decentralized cryptocurrency markets , positioning the network as foundational ordering infrastructure capable of handling the throughput requirements of financial applications.

Rollup-Based Smart Contracts

Smart contract functionality is planned via rollup-based solutions rather than native execution, allowing Kaspa to add programmability while maintaining the security properties of its base-layer proof-of-work consensus without increasing on-chain complexity.

Proof-of-Work Security Model

By maintaining proof-of-work consensus, Kaspa inherits PoW's well-understood security properties and permissionless mining model, while the BlockDAG structure addresses the scalability constraints that limit transaction throughput on traditional single-chain PoW networks.
