Kaspa processes 10 blocks per second using BlockDAG technology. With a May 2026 hardfork and 95% supply mined by July, here's what makes this L1 different.

Bitcoin processes one block every 10 minutes. Most chains that wanted to go faster switched to proof-of-stake. Kaspa took a different path entirely.
Instead of a linear blockchain where blocks form a single chain, Kaspa uses a BlockDAG (Directed Acyclic Graph) structure. Multiple blocks can be created simultaneously and reference each other in parallel. The GHOSTDAG protocol sorts these concurrent blocks into a consistent order, maintaining consensus without discarding any valid work.
The result: 10 blocks per second after the May 2025 Crescendo hard fork, with plans to push beyond 100 BPS through the upcoming DAGKnight upgrade. That's roughly 6,000 times faster block production than Bitcoin, while keeping proof-of-work security.
Kaspa was fair-launched in November 2021 with no pre-mine, no pre-sale, and no token allocations. It's 100% community-managed, which differentiates it from most venture-backed Layer 1 projects.
In a traditional blockchain, when two miners find a block at nearly the same time, one block becomes an orphan and gets discarded. This is why Bitcoin needs 10-minute block times: spacing out blocks reduces collisions.
GHOSTDAG flips this model. When multiple blocks arrive simultaneously, the protocol includes all of them and determines their ordering after the fact. Blocks reference multiple parents rather than a single predecessor, creating a graph structure instead of a chain.
This architecture eliminates the fundamental trade-off between block time and security that constrained proof-of-work chains for over a decade. Kaspa currently runs at roughly 1-second effective confirmation times with the network processing over 601 million total transactions since launch.
| Metric | Bitcoin | Ethereum | Kaspa |
|---|---|---|---|
| Block time | 10 min | 12 sec | ~1 sec |
| Blocks per second | 0.0017 | 0.083 | 10 |
| Consensus | PoW (SHA-256) | PoS | PoW (kHeavyHash) |
| Parallel blocks | No | No | Yes |
The biggest catalyst on Kaspa's roadmap is the Covenant++ hardfork, confirmed for May 5, 2026. This upgrade introduces three major capabilities to Layer 1:
Native Assets (KRC20): Token creation directly on Kaspa's base layer, similar to ERC-20 on Ethereum but running on the high-throughput BlockDAG.
Covenant++: Advanced spending constraints that enable lending protocols, automated market makers, escrow, and conditional transfers. These are programmable transaction rules without requiring a full virtual machine, keeping the UTXO model's efficiency.
Zero-Knowledge Verification: ZK proof support on Layer 1, enabling privacy features and scalability improvements.
The team also released SilverScript, a high-level programming language that compiles directly to Kaspa's native script. This lowers the barrier for developers building on the covenant system.
For context, Kaspa's STRICT score sits at 76.6/100, reflecting strong innovation (8.5/10) and solid tokenomics (7.8/10) balanced against ecosystem maturity risks.
While the hardfork will add L1 programmability, Kaspa already has Layer 2 smart contract capability through the Igra Network, which launched on mainnet January 26, 2026.
Igra brings EVM-compatible smart contracts with 3,000+ TPS, using Kaspa miners as decentralized sequencers. Its permissionless phase is expected in March 2026, and Q2 plans include support for multiple virtual machines: EVM, Move, and WASM. This means developers from Ethereum, Sui, and other ecosystems can port existing codebases with minimal changes.
A second Layer 2, the Kasplex zkEVM (launched August 2025), provides full Ethereum compatibility with Solidity support, MetaMask integration, and bridged KAS as gas.
Two competing Layer 2 solutions (Igra and Kasplex) give developers options and create healthy competition for the best execution environment on Kaspa.
Kaspa uses a "chromatic halving" emission schedule where block rewards decrease monthly rather than halving every four years like Bitcoin. As of March 2026, approximately 27.05 billion KAS are in circulation from a total supply of 27.26 billion.
By July 10, 2026, roughly 95% of total supply will be mined. This drastically reduces the rate of new KAS entering the market. For comparison, Bitcoin won't reach 95% until approximately 2032.
The network hashrate tells an encouraging story: 411 PH/s as of early March, up 32% from February's 311 PH/s. Miners are increasing investment even as rewards shrink, suggesting confidence in the protocol's long-term value.
Despite being a community-launched project, Kaspa has attracted institutional attention:
Exchange access remains limited compared to top-20 tokens. KAS trades on Bitget, Bybit, Kraken, KuCoin, and HTX (which added spot trading in December 2025), but Binance and Coinbase offer only futures. A spot listing on either exchange would be a significant catalyst.
The obvious question: if Solana, Sui, and Aptos already achieve high throughput with proof-of-stake, why does Kaspa's PoW approach matter?
Security model. Proof-of-work requires physical resources (hardware, electricity) to attack. PoS systems can theoretically be attacked through token accumulation. For users who value the security properties that made Bitcoin resilient, Kaspa offers those same guarantees at modern speeds.
Decentralization. Fair launch with no pre-mine means no concentrated token holdings from VCs or insiders. The 47+ active Rust contributors and community governance reflect genuine distributed control.
DAGKnight (upcoming). Post-hardfork, the DAGKnight consensus upgrade will introduce adaptive, latency-aware block ordering with sub-second finality. Developers estimate that with DAGKnight and vProgs combined, Kaspa could scale beyond 30,000 TPS, rivaling dedicated high-throughput PoS chains.
The trade-off is ecosystem maturity. Solana and Ethereum have years of DeFi development, established developer tools, and deep liquidity. Kaspa's DeFi ecosystem is just beginning.
No analysis is complete without addressing the risks:
Ecosystem gap. Even with two Layer 2 solutions live, Kaspa's DeFi TVL and dApp count lag far behind established L1s. Developers need to build the tooling and applications that attract users.
Exchange access. Not being on Binance or Coinbase spot limits retail accessibility. The fair launch model, while a strength for decentralization, means no token allocations for exchange listing incentives.
Execution risk. The May hardfork introduces significant complexity with native assets, Covenant++, and ZK verification. DAGKnight adds adaptive consensus on top of that. Each upgrade carries implementation risk.
Price performance. KAS currently trades around $0.039, still down approximately 81% from its August 2024 all-time high of $0.207. The extended downtrend suggests the market is waiting for catalyst delivery before repricing.
Three milestones will determine Kaspa's trajectory in 2026:
March 2026: Igra Network permissionless launch. First real test of developer and user adoption for Kaspa's DeFi ecosystem.
May 5, 2026: Covenant++ hardfork. The most significant upgrade since Crescendo. Success here validates the roadmap; failure or delay could damage confidence.
July 2026: 95% supply mined milestone. Reduced emissions combined with growing demand (if ecosystem delivers) create conditions for supply-driven price appreciation.
For those interested in the technical fundamentals, Kaspa represents a genuine architectural experiment: proving that proof-of-work blockchains can match modern performance without sacrificing the security properties that made them valuable in the first place.
