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.
4/ Progress Update - 3:00 AM PST

Validators on Shard 0 and 1 were provided with a new version of the node binary by the Harmony Core team.

Network remains halted but bandwidth usage has reduced.
5/ Progress Update - 5:00 AM PST

Our team was on an active call discussing the issue and its solutions. The team has also designed a specific binary to combat spam.

Important note: The spam that has halted the network are NOT of arbitrage trading bots.
6/ Progress Update - 5:40 AM PST

Our team is changing internal policies around running new builds on internal nodes.

More information on this will be out in the official postmortem.
7/ Progress Update - 6:30 AM PST

Our team has successfully installed a new build on internal servers in specific regions.

Good news: Outbound spam traffic reduced by about 50%.

The new build shall be installed in additional servers in more regions.
8/ Progress Update - 6:45 AM PST

Our team critically monitored the build to spot any issues before rolling it out to validators.

Good news: Current results showed high promise.
9/ Progress Update - 7:30 AM PST

To reduce logging, a change was made to the binary. This has been deployed to Shard 0 and 1 RPCs.

Shard 2 and 3 are being monitored as they haven’t faced an outage yet.
10/ Progress Update - 7:45 AM PST

The new build was installed on internal validator nodes.

Constant monitoring shows reductions in traffic.
11/ Progress Update - 9:00 AM PST

New build has been released to validators on Shard 0 and 1.

Blockchain can run but awaits the achieving of 66% consensus.

External validators on blocks 0 and 1 were executing the upgrade as the consensus stood at 53%.
12/ Progress Update - 9:30 AM PST

Shard 0 achieves consensus. But, consensus is unstable and more validators are needed on shard 0 on the update.

Shard 1 hasn’t moved yet.

External validators on shard 0 and 1 MUST update their nodes to the newest build.

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.

👇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.

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

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 👇

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.


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

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.
