DuskDS Doesn't Store What Happened. It Stores Proof That It Happened."
Assumed the base layer of any blockchain has to hold the full history — every transaction, every state change, sitting there for anyone to verify from scratch. DuskDS doesn't work that way.
DuskDS, Dusk's settlement and data-availability layer, only stores succinct validity proofs. The actual execution-heavy state — the detailed transaction data, the contract logic results — lives up on the application layers like DuskEVM instead. DuskDS just holds compact cryptographic proof that the execution was done correctly, not the execution itself.
The stated reason is direct: it keeps full-node hardware requirements low. You don't need to store or replay everything ever executed on every layer just to run a validating node on the base chain. That's a real, practical win for decentralization — cheaper hardware means more people can actually run a node.
Here's the part I kept turning over. If DuskDS only checks that a proof is valid, someone still had to generate that proof by actually running the full execution — batching transactions, computing the resulting state, compressing it down to something succinct. That work doesn't disappear, it just moves to whichever layer produces the proof, like DuskEVM's sequencer. Lighter base-layer nodes are real. But "lighter" here means the heavy lifting happens somewhere else, by someone else, and DuskDS is trusting the math of the proof rather than re-doing the work itself.
That's a legitimate trade-off, not a hidden flaw — succinct proofs are exactly what let you trust the output without redoing the input. But it does shift the question from "is the base layer decentralized" to "is whoever's generating these proofs decentralized too.
