ZeroSync allows to verify Bitcoin’s chain state in an instant. No need to download hundreds of gigabytes of blocks. A compact cryptographic proof suffices to validate the entire history of transactions and everyone’s current balances.

Actually demo here.
Can a zero-sync node validate new transactions, or does it first sync using STARK proof, then begin to validate? This is really great, because it takes forever to sync the entire blockchain and it’s only going to get bigger. Imagine a blockchain that contains a ton of data like terabytes, could this lead to significantly improving bandwidth and storage capabilities of blockchains?
It does this I believe. You also need someone to generate the proofs. But that can be a single untrusted entity.
You still need the resulting state to be stored somewhere. But it makes light clients and syncing fullnodes much much easier, no need to download the blocks and process the txs.
Cryptocurrency is off topic.
The cryptography that is discussed is not.
