About
What Is KASPA (KAS)?
Kaspa is a fast, scalable Layer-1 cryptocurrency built on proof-of-work (PoW) and powered by the GHOSTDAG protocol — a novel consensus mechanism that extends Nakamoto’s original design. Unlike traditional blockchains that discard competing blocks, GHOSTDAG allows parallel blocks to coexist and orders them within a Directed Acyclic Graph (blockDAG), enabling high throughput while preserving decentralization and security.
Kaspa currently processes 10 blocks per second, with a long-term goal of scaling to 100 blocks per second, offering confirmation times limited only by internet latency. This level of performance was made possible by the Crescendo upgrade — a hardfork that successfully increased Kaspa’s block rate to 10 BPS while maintaining network stability.
Kaspa's mission is to create a PoW that operates with internet speed, combining the reliability of proof-of-work with the responsiveness demanded by modern applications.
True to its foundational principles, Kaspa is engineered for accessibility and decentralization. Its full node runs smoothly on a standard PC, requiring modest hardware thanks to efficient multithreaded CPU use and a secure pruning mechanism that limits disk usage while preserving cryptographic integrity. This design reflects Satoshi’s original vision — a decentralized network where anyone can participate fully without specialized equipment.
Layer-2 solutions are in active development to further expand Kaspa’s capabilities. These efforts aim to leverage Kaspa’s unique architecture — particularly its multi-leader consensus — to support scalable applications, MEV resistance, decentralized oracles, and secure sequencing for broader ecosystem growth.
Who Are the Founders of Kaspa?
Kaspa’s originator is Dr. Yonatan Sompolinsky (Harvard University), whose research under Prof. Aviv Zohar (Hebrew University) introduced scalable proof-of-work protocols that generalize Nakamoto Consensus.
The project began through DAGLabs a research company founded by Sompolinsky and funded by Polychain Capital. Elichai Turkel, also a Bitcoin Core contributor, served as DAGLabs’ applied cryptographer during its development phase. DAGLabs was dissolved around the time of Kaspa’s fair launch in November 2021, transitioning the project to a decentralized, community-led model.
Kaspa’s ongoing development and research are driven by a global group of contributors who maintain and advance the protocol. A list of active contributors can be found on Rusty Kaspa’s contributor page and at research.kas.pa.
Kaspa remains an open-source, permissionless project with no central governance or business model.
What Makes Kaspa Unique?
Kaspa is unique in its ability to support high block rates while maintaining the level of security offered by proof-of-work environments. Kaspa’s current main net operates at 1 block per second. Down the road, core developers and researchers will work on stretching the capability to the limits—think 10 or even 100 blocks per second.
Kaspa also includes a unique monetary policy which decreases emissions geometrically over time based on the 12-note scale of music. Known as the chromatic phase - this policy activated May 7th 2022 with a block reward of 440 KAS. The block reward will be halved once per year, but smoothly: every month, the block reward is reduced by a factor of (1/2)^(1/12). This means that the ratio of block rewards in consecutive months is exactly the same as the ratio of frequencies of two consecutive semitones in a tempered chromatic scale. The initial block reward is the frequency of the note A4, and every averaged year is hence called an octave.
Note that the policy dictates how many coins are minted per second regardless of the block rate. Should Kaspa change the block rate in the future, the reward will be adjusted accordingly to maintain the same emission rate.
How Many Kaspa (KAS) Coins Are There in Circulation?
There are around 25.1 billion KAS in circulation as of NOV 2024.
How Is the Kaspa Network Secured?
Kaspa network is secured by miners through Proof of Work and uses an algo known as k-Heavyhash.
Heavyhash was chosen for forward-compatibility with Photonic miners when they became available.

What blockchain does Kaspa use? Is it its own blockchain or built on top of another?
Kaspa operates on its own blockchain, not as a layer built on top of another blockchain. It is a standalone, independent blockchain designed to address scalability, security, and decentralization challenges.
Key Features of Kaspa's Blockchain:
- GHOSTDAG Protocol – Kaspa uses a unique consensus mechanism called GHOSTDAG, which is an evolution of the GHOST (Greedy Heaviest Observed Subtree) protocol used in Bitcoin. This allows for parallel block production, enabling high throughput and scalability.
- DAG (Directed Acyclic Graph) Structure – Unlike traditional blockchains that process transactions sequentially, Kaspa organizes blocks in a DAG structure, allowing multiple blocks to be mined simultaneously.
- Proof-of-Work (PoW) Consensus – Kaspa is a minable blockchain, similar to Bitcoin, but with a more efficient consensus model.
- High Throughput & Low Latency – Kaspa aims to achieve high transaction speeds (thousands of transactions per second) while maintaining security and decentralization.
Comparison to Other Blockchains:
- Not a Layer-2 or Sidechain: Kaspa is not built on top of Ethereum, Bitcoin, or any other blockchain. It is a base-layer blockchain with its own native cryptocurrency (KAS).
- Not a Fork of Bitcoin or Ethereum: While it borrows some concepts (like PoW), it is a completely new blockchain designed from the ground up.
Conclusion:
Kaspa is an independent blockchain with its own consensus mechanism, architecture, and token. It does not rely on another blockchain for security or functionality.

Is Kaspa programmable? Does it support smart contracts or decentralized applications?
As of my latest knowledge, Kaspa (KAS) is primarily designed as a high-throughput, scalable blockchain focused on fast, secure, and decentralized transactions. However, it does not natively support smart contracts or decentralized applications (DApps) in the same way that Ethereum, Solana, or other smart contract platforms do.
Key Points About Kaspa's Programmability:
No Native Smart Contracts
- Kaspa's current architecture is optimized for high-speed transactions (using a GHOSTDAG consensus mechanism) rather than executing complex smart contracts.
- Unlike Ethereum or Solana, it does not have a built-in Turing-complete virtual machine (like EVM or Solana's Sealevel).
Potential for Future Developments
- The Kaspa team has mentioned exploring layer-2 solutions or sidechains that could enable smart contract functionality in the future.
- Some developers in the community are experimenting with off-chain computation or oracles to extend Kaspa's capabilities.
Alternative Use Cases
- Kaspa is well-suited for fast, low-cost transactions, making it a strong candidate for payment systems, DeFi, and tokenization (via simple token standards like Kaspa Improvement Proposals (KIPs)).
- Some projects are building lightweight applications on top of Kaspa, but these are not traditional DApps.
Conclusion:
Currently, Kaspa is not programmable in the sense of supporting smart contracts or DApps. However, future upgrades or layer-2 solutions could change this. If you're looking for a blockchain with strong smart contract capabilities, alternatives like Ethereum, Solana, or Cardano might be more suitable.

How much data can I store on the Kaspa blockchain? Does it support on-chain data storage?
The Kaspa blockchain is primarily designed as a high-throughput, scalable, and decentralized cryptocurrency network, similar to Bitcoin but with a focus on speed and efficiency. However, its capabilities for on-chain data storage are limited compared to dedicated storage-focused blockchains like Arweave, Filecoin, or IPFS.
Kaspa’s Data Storage Capabilities
Transaction Data (Limited Storage)
- Kaspa allows users to include arbitrary data in transactions (similar to Bitcoin’s OP_RETURN or Ethereum’s smart contract storage).
- However, block size limits and network consensus rules restrict how much data can be stored per block.
- Kaspa’s GhOSTDAG consensus mechanism prioritizes speed and scalability, but it does not explicitly optimize for large-scale data storage.
No Native Smart Contracts (Yet)
- Unlike Ethereum or Solana, Kaspa currently does not support smart contracts, meaning there’s no built-in way to store and retrieve data programmatically.
- Future upgrades (if implemented) could introduce smart contract functionality, potentially enabling more advanced data storage solutions.
Off-Chain Storage Options
- For large-scale data storage, Kaspa users would likely need to rely on off-chain solutions (e.g., IPFS, Arweave, or decentralized storage networks) and reference the data via on-chain hashes (similar to how Bitcoin and Ethereum handle large files).
Comparison with Other Blockchains
| Blockchain | On-Chain Storage | Smart Contracts | Best For |
|---|---|---|---|
| Kaspa | Limited (transaction data) | No (as of now) | Fast, scalable transactions |
| Bitcoin | Limited (OP_RETURN) | No | Secure, censorship-resistant transactions |
| Ethereum | Limited (contract storage) | Yes | Smart contracts & DeFi |
| Arweave | Permanent storage | No | Decentralized file storage |
| Filecoin | Permanent storage | No | Decentralized cloud storage |
Conclusion
- Kaspa is not optimized for large-scale on-chain data storage but can store small amounts of data in transactions.
- For permanent, scalable storage, you’d need to use off-chain solutions (like IPFS or Arweave) and reference them on-chain.
- If Kaspa introduces smart contracts in the future, data storage capabilities may improve.
