Kaspa in 60 seconds

Kaspa is digital cash secured by proof of work, like Bitcoin — but built to be fast.

Most blockchains make one block at a time and throw away ties. Kaspa keeps every block and weaves them into a blockDAG blockDAG A block structure where blocks can have many parents, so parallel blocks are kept instead of discarded. Kaspa's blockDAG is what lets it run many blocks per second under proof of work. — a braid instead of a single chain — ordered by a protocol called GHOSTDAG GHOSTDAG The protocol that puts every block of the blockDAG into one agreed order without throwing parallel blocks away — the reason Kaspa keeps Bitcoin-style security at high block rates. . The practical result: blocks arrive many times per second and payments confirm in seconds, while keeping Bitcoin-style proof-of-work security.

A chain is a single-lane road; a blockDAG is a motorway where every lane's traffic still ends up in one agreed order.

The catch — until 2026

For years Kaspa's scripting was deliberately minimal. It could verify who owns coins and move them, but it couldn't enforce conditions on how coins move next. No vaults, no chain-enforced tokens, no on-chain agreements — money only.

That is what the Toccata upgrade changed, and it's why this site exists.
