Kaspa’s BlockDAG Design and GHOSTDAG Consensus
Summary
The document explains how Kaspa’s BlockDAG architecture differs from a linear blockchain: multiple blocks can coexist, while GHOSTDAG orders and validates them. It presents this design as a way to improve throughput and scalability while retaining proof-of-work security. The article also describes the Crescendo upgrade, which it says increased block generation from one block per second to ten, and gives claims about transaction throughput and finality.
It discusses possible payment and decentralized application uses, along with token supply figures and the need to attract developers. The evidence is descriptive rather than comparative: no benchmark setup, independent validation, or detailed security analysis is provided. The article notes that adoption remains limited, so its performance claims and predictions about future ecosystem growth should be treated as claims in need of external verification.
Key ideas
- Kaspa’s BlockDAG allows multiple blocks to coexist instead of requiring a single linear sequence.
- GHOSTDAG orders and validates those blocks to maintain network consistency.
- The article attributes higher capacity to the Crescendo upgrade and faster block generation.
- Proof of work is presented as the network’s security model, with energy use acknowledged as a concern.
- Developer adoption and limited current use in DeFi and applications remain challenges.
