I keep hearing BlockDAG
Start with what Kaspa is, then work through the interactive demo. No SDK, no install — just the ideas, with things you can poke.
Build on Kaspa
Kaspa keeps every block instead of throwing parallel work away. Here is how that works, and how to build on top of it.
Three ways in
I want to ship an app
Choose your stack, then get a node and a network. You need the UTXO model first if you are coming from an account-based chain.
I want to write contracts
Read the map before anything else. Kaspa Script, Silverscript and Argent are one stack; Toccata, vProgs and L2s are not. Getting that wrong costs weeks.
Why another Kaspa site
The official documentation is reference: precise, generated, and the right place to look up a method signature. This site is the part that reference cannot be — an order to learn things in, explanations you can interact with, and a straight answer about which tool to use and how finished it is.
Where a fact belongs upstream, this site links to it rather than copying it. Reference that gets copied goes stale silently, and a stale page is worse than a missing one.
