Kaspa Updates 2025: Network Upgrades, On-Chain Growth, and Real-World Usage

Kaspa’s 2025 updates focus on one clear outcome: running a proof-of-work blockchain at high speed without weakening decentralization or security. The most important change came in May 2025, when the Crescendo hardfork raised Kaspa’s block rate from 1 block per second to 10 blocks per second. Since then, the network has recorded higher transaction throughput, lower confirmation times, and new applications that use Kaspa’s base layer directly.

What Changed on Kaspa in 2025?

Kaspa’s main update in 2025 was the Crescendo v1.0.0 hardfork, which went live on May 5, 2025. The upgrade was mandatory and activated once the network’s Difficulty Adjustment Algorithm score reached 110,165,000, at around 15:00 UTC.

The hardfork was based on Kaspa Improvement Proposal 14, often called KIP-14. Its goal was simple: increase block production while keeping proof-of-work security intact.

Before Crescendo, Kaspa produced one block every second. After the upgrade, the network now produces ten blocks per second, or one block every 100 milliseconds.

This change affects how fast transactions are processed, how many transactions the network can handle, and how applications behave on top of Kaspa.

Why does block speed matter?

Most proof-of-work blockchains struggle with speed. Bitcoin, for example, produces one block roughly every ten minutes. Ethereum Classic produces blocks faster, but still follows a single-chain structure that limits parallel processing.

Kaspa takes a different approach by using a blockDAG, or directed acyclic graph, instead of a single chain. With a blockDAG, multiple blocks can exist at the same time and still be ordered through consensus.

Kaspa’s GHOSTDAG protocol handles this ordering. Instead of discarding blocks created at the same time, the protocol includes them and sorts them using a topological order.

With the Crescendo upgrade, this design now operates at a much higher rate.

How does the Crescendo hardfork improve Kaspa’s performance?

The Crescendo upgrade introduced several technical changes beyond faster block production.

Here is what changed at the protocol level:

• Block rate increased from 1 block per second to 10 blocks per second
• Time between blocks reduced from 1,000 milliseconds to 100 milliseconds
• GHOSTDAG K parameter increased to 124
• Maximum block parents increased from 10 to 16
• Transition to P2P Protocol Version 7 for node communication

These changes allow Kaspa to process more transactions at the same time without increasing block size or centralizing node requirements.

At peak activity in September 2025, Kaspa processed up to 60 transactions per second at the base layer. That figure exceeded Bitcoin’s average of about seven transactions per second on the same day.

On-chain Activity on Kaspa

Kaspa’s transaction data shows a sharp rise in activity during 2025.

On September 14, the network recorded 1,918,960 transactions in a single day. That was up from about 821,000 the day before, a rise of roughly 134 percent.

Daily active addresses crossed 500,000 in September, matching Bitcoin’s levels during the same period. Unique addresses also grew several hundred percent year over year, partly driven by tests involving KRC-20 tokens.

Transaction fees remained below $0.001 per transfer. At the same time, Ethereum’s average fee during that period was around $0.47.

How does Kaspa compare to Bitcoin and Ethereum?

Bitcoin processed about 579,000 transactions on September 14. Ethereum processed about 1.637 million transactions on its mainnet the day before, with millions more on layer-2 networks like Base.

Kaspa sits between them in raw volume, but differs in design.

Key differences include:

• Kaspa processes blocks in parallel, Bitcoin does not
• Kaspa scales at Layer 1, Ethereum relies heavily on Layer 2
• Kaspa confirmation times are measured in seconds
• Kaspa fees stay low during high activity

On September 14, Kaspa had processed around 1.4 million parallel blocks. Bitcoin’s total block count since 2009 was about 914,000 at that time.

What is Kasia and How Does it Use Kaspa?

One of the most visible applications built on Kaspa in 2025 is Kasia, a decentralized peer-to-peer messaging app.

Kasia was introduced by the Kaspa community in June and later went live on Google Play on October 12. The project is led by developer @auzghosty and is open source.

Kasia records each message as a Layer 1 Kaspa transaction. Messages are encrypted end to end and stored on-chain, not on centralized servers.

To use Kasia, users need a Kaspa wallet and at least 10 KAS. Each message costs about 0.00001791 KAS. With 10 KAS, users can send over 500,000 messages, which works out to about $0.74 at current prices.

Because Kasia uses Kaspa’s blockDAG, messages confirm quickly and work in near real time.

What Other Applications Launched on Kaspa in 2025?

Kaspa also saw several infrastructure and tooling projects appear in 2025.

These include:

• Kaspa File Storage, a decentralized system for uploading encrypted files to the blockchain
• Navigate, a Kaspa-focused Web3 browser with wallet support, on-chain chat, and KNS domains
• K Social, an on-chain microblogging app where posts are written directly into Kaspa transactions

K Social uses a simple architecture made up of a Kaspa node, an indexer, and a frontend. Social data lives on-chain, while indexers make it readable. There is no central moderation system.

These projects rely on Kaspa’s fast confirmation times and low fees to function smoothly at the base layer.

How is Kaspa Addressing Long-Term Security Risks?

In August 2025, a community developer proposed a quantum-resistant wallet upgrade.

The proposal suggests moving from Pay-to-Public-Key addresses to P2PKH-Blake2b-256-via-P2SH addresses. This hides public keys until funds are spent, reducing exposure to future quantum attacks that could break elliptic curve cryptography.

The change would be voluntary and wallet-level only. It would not require a hardfork or consensus change.

Worth noting, Kaspa’s node count increased steadily in late 2025. On October 27, the network had 443 online nodes, up from the low 300s a week earlier.

More nodes improve resilience, reduce reliance on specific regions, and make consensus harder to influence.

HTX Listed Kaspa (KAS) With Spot and Margin Trading

HTX listed Kaspa (KAS) on December 24, 2025, expanding market access for the GHOSTDAG-based blockchain. The exchange will launch spot trading for the KAS/USDT pair alongside isolated margin trading with up to 10x leverage.

According to HTX, KAS deposits opened at 15:00 UTC on December 19, 2024. Spot trading is scheduled to begin at 09:00 UTC on December 24, 2025, followed by withdrawals at 09:00 UTC on December 25. Isolated margin trading for KAS/USDT went live at the same time as spot trading.

Conclusion: What Kaspa achieved in 2025

Kaspa’s 2025 updates focused on execution rather than promises. The Crescendo hardfork raised block speed, improved throughput, and supported real applications at the base layer. Transaction counts increased, fees stayed low, and node participation grew.

Kaspa remains a proof-of-work network that prioritizes decentralization while operating at speeds usually associated with different architectures. The data from 2025 shows that its blockDAG design can support sustained activity without relying on layer-2 systems for basic scaling.
