1/ #Rollups (Layer2) are blockchain technologies that help scale Layer1s (ex: Ethereum), that allow faster transactions at a cheaper cost in a trustless verifiable way.
In ZK-Rollups, validity is ensured by zero-knowledge proofs.

2/ Zero-knowledge proof (ZK Proofs) technologies enable one party to prove to another party that they know something without the prover having to convey the information itself in order to prove their knowledge.

3/ ZK for Scalability 📈
Since ZK proofs allow data-sharing between two parties without transferring any information with the transaction, they can improve scalability.
With 2-second finality already achieved, @Harmonyprotocol can scale its transactions/second with sharding.

4/ However, a bottleneck to scalability is state bloat. As more transactions are being done on the network, the bloat issue is imminent.
While experts have explored state expiry & weak statelessness to solve the issue, #Harmony shall explore them in detail for efficient adoption

5/ ZK for Privacy 🔒
Blockchain is fully transparent. Open txn data may result in malicious activity, front-running & degrading the value of a DeFi system.
Privacy technology is needed to shield users and their transactions from malicious attacks yet can be fully validated.

6/ In general, Privacy is confidentiality (hiding payment amounts) + anonymity (hiding the identities of senders & recipients).
While there are some challenges to achieving total privacy, some techniques for achieving transaction privacy are ZK proofs, Mixers & Secret Networks.

7/ ZK for Interoperability 💻💻
Harmony's trustless bridge deploys light clients to facilitate cross-chain transactions. However, the client requires downloading all the epoch blocks from genesis and verifying BLS aggregated signatures, which can be time and space inefficient.

8/ Therefore, a simple ZK-based light client can be designed to make it fast & cheap. It can be designed to only require downloading the latest proof & verifying it to sync to the latest state of the Harmony blockchain to get the trustable epoch committee validate user proofs.
9/ At @Harmonyprotocol, our goal is to bring the best research to the product, fast! Therefore, in early 2022, we will be identifying the key infrastructure elements that will facilitate builders on Harmony to adopt ZK tech.
