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.

open.harmony.one/harmony-in-202…
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.

👇Here's why it is important, and what we are doing about it
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.

1/ We are undergoing an outage due to multiple block propagation issues. Heavy spam traffic in the past 30 hours has halted the network.

Our core team is working with validators & internal leader nodes to resolve the outage.

Minimum gas upped to 30 gwei to prevent spam attacks
2/ Progress Update - 1 AM PST

Validators have been advised to downgrade their node binaries to a previous version as the bandwidth of validators with V4.3.2 were overburdened.

Our team is working on a special version of validator node binary to reduce bandwidth usage
3/ Progress Update - 1:30 AM PST

Our team is internally testing new versions of Shard 0 that could potentially restore the blockchain.

1/ Harmony community, @harmonyprotocol is now officially migrating its governance requirements to Snapshot.org (@SnapshotLabs)

All #HarmonyONE DAOs rely on Snapshot to run important elections such as protocol proposals & electing DAO governors

medium.com/harmony-one/ha…
2/ @Harmonyprotocol is now fully supported on Snapshot, and the forked version hosted on the Harmony website will be discontinued.

This decision comes to ensure complete decentralization and to provide a reliable and secure product to the community.
3/ With an ever-growing number of DAOs on Harmony and a plan to create many more, it is critical they have access to reliable services to run and manage their organizations.

Therefore, from March 1st, 2022, users will need to create a brand new space on Snapshot.org

1/ We are excited to announce that @CelerNetwork has extended support to @harmonyprotocol.

ONE users can now use the multi-chain 'cBridge' to transfer $USDC and $WETH instantly and at a low-cost.

More ⬇️
2/ Celer is also launching liquidity mining sessions with nearly 40000 $CELRs as daily rewards!

👀

3/ The Network’s cBridge recently surpassed $2B in total cross-chain transaction volume.

Using the cBridge, Harmony ONE users can transact with other chains like Ethereum, BSC, Polygon & more.

Know more @CelerNetwork & their cBridge 👇

26/ PRIVACY RIGHTS

While crypto entrepreneurs should set clear guidelines on KYC/AML reporting while preserving privacy, peer-to-peer transaction reporting & disclosure requirements on self-custody assets are unconstitutional overreaches. Get a warrant, or we’ll see you in court
27/ While it is built for decentralization, using crypto for nefarious purposes leaves an excellent paper trail for prosecutors to lock in a conviction. People who build products that aim to serve dark markets almost always get caught & go to jail.

28/ LAYER 1 PROTOCOLS

ETH sits at ~60% market cap dominance [vs 98% in early 2021] among Layer 1s, & it’s likely that we’ll see >80% of on-chain EVM transaction volume move to L2 chains within the next year. Time is of the essence as other Layer 1s continue to gain market share.

1/ @MessariCrypto’s #theses2022, synthesizing the crypto chaos, encompasses the web3 economy & infrastructure that includes crypto, DeFi, NFTs & bridges!

👇 Here are some passages that show how @harmonyprotocol's vision and strategies align with the market potential & key trends
2/ WEB3 VISION

Web3 encompasses cryptocurrencies, smart contract computing, decentralized hardware infrastructure, NFTs, DeFi, Metaverse & DAOs.

The report envisions Web3 will show growth everywhere, particularly in NFT infrastructure, DAO tooling and inter-protocol bridges.
3/ With DeFi, NFTs & the user-owned economy, Web3 gives us the chance to upgrade networks into crypto asset centered economies & build systems where the incentives of network owners, network participants, and third-party developers are fully aligned.
