Kaspa: digital silver

Kaspa At a Glance

Kaspa is a proof-of-work cryptocurrency that stays true to Satoshi Nakamoto's vision—decentralized, secure digital money—while fixing Bitcoin's speed limitations.

It uses blockDAG (Directed Acyclic Graph) instead of a traditional blockchain, allowing multiple blocks to be created in parallel (~10 blocks per second) while maintaining decentralization.

The ecosystem is expanding with L2 solutions (Kasplex, Igra) today and a longer-term vision called vProgs for native smart contracts using zero-knowledge proofs.

What is Kaspa?

Kaspa aims to realize Satoshi Nakamoto's vision of fast, decentralized, secure digital money—but with modern upgrades.

It improves on Bitcoin's original design by replacing the single-chain blockchain with a "blockDAG." Instead of adding blocks one at a time, blockDAG allows many blocks to be created simultaneously and connects them in a network (Directed Acyclic Graph).

The GHOSTDAG protocol orders any conflicting blocks to maintain consensus.

Note: The Crescendo hardfork (May 5, 2025) upgraded the network from 1 BPS to 10 BPS. Higher rates (~32 BPS) are longer-term targets.

Kaspa maintains proof-of-work mining with no pre-mine and no central authority—though ASICs now dominate the network hashrate, making GPU mining mainly a hobbyist pursuit.

Why I'm Interested

As a developer who values open-source principles, Kaspa caught my attention because:

• Technical approach: The blockDAG architecture is an elegant solution to the throughput vs. decentralization tradeoff
• Active development: The core team has been steadily improving the protocol, with smart contract capabilities on the horizon
• vProgs vision: Native smart contracts with off-chain execution and on-chain verification using zero-knowledge proofs (more on this below)

I've started learning smart contract development and EVM programming to be ready when these capabilities become available.

Smart Contracts: Current and Future

Kaspa started as a pure currency. The ecosystem is now expanding with multiple approaches to programmability:

Available Today:

• KRC-20: Token standard using L1 data insertion and off-chain indexing

In Development:

• Kasplex L2: Planned Ethereum-compatible L2 with LUA VM targeted for December 2025
• Igra Labs: EVM-compatible ZK rollup (testnet live, mainnet targeted early 2026)

Long-term Vision:

• vProgs: Native smart contracts built into L1 (see below)

vProgs: Off-Chain Execution, On-Chain Verification

vProgs (Verifiable Programs) represent Kaspa's long-term approach to smart contracts. The key idea: instead of executing contracts on-chain (slow and expensive) or on separate L2s (fragments liquidity), vProgs execute off-chain and prove correctness using zero-knowledge proofs. The blockchain only verifies the proof.

How it works: Think of vProgs like apps that run independently but can interact when needed. A token swap might involve three vProgs—a price oracle, trading app, and stablecoin manager—each generating proofs that combine into one atomic transaction.

Claimed benefits (per BSC News analysis):

• Efficient verification instead of full re-execution
• Multiple vProgs can interact in single transactions
• "ScopeGas" fee system for spam protection

Current status: The vProgs Yellow Paper (Draft v0.0.1) was released September 2025. This is early-stage research—timelines are speculative and depend on development progress, testing, and audits.
