1. General presentation

Kaspa (KAS) is a blockchain designed to be fast, scalable and secure, with a unique approach based on a DAG (Directed Acyclic Graph) rather than a traditional linear block structure.

Creator : Yonatan Sompolinsky and a team of blockchain researchers.
Consensus mechanism : GHOSTDAG (an improvement to Proof-of-Work).
Native token : KAS, used for miner transactions and rewards.
TPS (transactions per second) : Currently ~10,000 TPS, scalable to several hundred thousand with adoption.
Finalization time : Approximately 1 second.
Launch : 2021.

2. Architecture and technology

Kaspa introduces a revolutionary approach by modifying the traditional blockchain structure:

✅ GHOSTDAG (Greedy Heaviest Observed Subtree Directed Acyclic Graph)

Unlike Bitcoin and Ethereum where a single chain is built block by block, Kaspa allows multiple blocks to be created in parallel and merged securely.
This significantly reduces transaction times and increases scalability.

✅ Pure Proof-of-Work (PoW), but improved

Unlike Bitcoin, Kaspa does not rely on forks or block speed reductions to ensure security.
It uses an advanced version of PoW that allows for near-instant confirmations.

✅ No premining or ICO

The project started in a completely decentralized manner, without prior fundraising, which makes it more resilient to criticism of the initial distribution of the token.

✅Infinite scalability (theoretically)

Thanks to GHOSTDAG, Kaspa can adapt to network traffic and support a huge number of transactions, without compromising security.

3. Benefits of Kaspa

✅Ultra-fast

Transactions are confirmed in less than a second, much faster than Bitcoin (10 min) or Ethereum (12 sec).

✅ Massive scalability

Unlike Bitcoin and Ethereum which are limited by their on-chain structure, Kaspa can support a much larger number of simultaneous transactions.

✅ True Proof-of-Work without compromise

Unlike other scalability solutions (Solana, Avalanche) which use Proof-of-Stake, Kaspa maintains the security and reliability of PoW, while being much faster than Bitcoin.

✅ Reinforced decentralization

No ICO or premining: All KAS tokens have been mined from scratch, preventing excessive concentration of wealth from the start.

✅ Low transaction costs

Despite a PoW mechanism, Kaspa optimizes fees, making them very low compared to Bitcoin and Ethereum.

4. Disadvantages of Kaspa

❌ Competition with Bitcoin and Ethereum

Bitcoin is already firmly established as the benchmark for PoW, and Ethereum has successfully transitioned to Ethereum 2.0. Kaspa must therefore prove that it provides significant added value.

❌ Not yet widely adopted

Despite its advanced technology, Kaspa is still relatively unknown and does not yet benefit from a solid DeFi/NFT ecosystem.

❌ High energy consumption

Although more efficient than Bitcoin, Kaspa remains a PoW project, and therefore energy-intensive, which may pose a problem for its adoption in a context where sustainability is increasingly prioritized.

❌ Less compatibility with EVM

Unlike Avalanche or Polygon, Kaspa is not compatible with the Ethereum Virtual Machine (EVM), which complicates the integration of existing Ethereum applications.

5. Conclusion: Is Kaspa a good project ?

Kaspa is one of the most innovative Proof-of-Work blockchain projects since Bitcoin. Its use of GHOSTDAG allows it to solve the main problem of PoW: slow transactions and network congestion.

With confirmations in less than a second, almost infinite scalability and true decentralization (no ICO, no pre-mining), Kaspa has strong potential to become a fast and secure payment network.
