Introduction to DEKU, a Parametric Sidechain on Tezos
summary
DEKU is a parametric sidechain framework that launches a permissioned Tezos sidechain with a WebAssembly VM, a CLI and Go and TypeScript SDKs, runs an alphanet on Carthage/testnet, and posts a state root hash to a Tezos vault contract for external verification. It claims 5k TPS observed in ticket-transfer benchmarks (20k on a development branch), uses in‑memory state for speed, offers 2 second finality, and demos a CQRS-style counter app showing live deploy, transaction submission, and state updates.
