After two weeks of workshops and rigorous testing, we are happy to report that Mainnet Rehearsal has officially concluded! The IoTeX Foundation and 50+ IoTeX Delegates worked as a team and we are extremely happy with the process and results, which even exceeded our expectations. Thank you to our amazing Delegates for your efforts and teamwork!

On April 9, IoTeX Foundation hosted Orientation Call #2, the fourth and final Mainnet Rehearsal event. We had 55+ participants that joined our global conference call — the highest attendance of all Mainnet Rehearsal events! This shows the interest and commitment from our Delegates is only getting stronger — we can’t wait to build the future of IoTeX together.

Key Takeaways from Mainnet Rehearsal

The primary goals of Mainnet Rehearsal were to 1) properly train Delegates to run consensus for IoTeX, and 2) pressure test and improve our Mainnet code. Today, Delegates are consistently mining REAL blocks using the REAL Mainnet code on REAL servers. We are proud to report we accomplished both of our primary goals — the Mainnet Rehearsal was a huge success!

Current status of Mainnet Rehearsal blockchain: https://t.iotex.me/chainhealth

IoTeX Mainnet Rehearsal lasted ~2 weeks and included two Consensus Rehearsals (bootstrapping a new blockchain from scratch) and two Orientation Calls (technical workshops from IoTeX Foundation). Throughout the Mainnet Rehearsal, we greatly improved the performance and security of the IoTeX blockchain and helped Delegate setup/optimize their nodes. Key takeaways include:

Multiple code releases + updates : Mainnet Rehearsal started with Testnet v0.5.0-rc6, and new code releases (rc7, rc8, rc9) were launched every week with bug fixes, new features, and improved performance.

Load tests and “fire drill” practice : we rapidly injected transactions (300+ finalized TPS) to test the limits of our blockchain, and practiced how to handle rare “fire drill” incidents — practice makes perfect!

This tool is not only for Delegates — please try it out for yourself!

Rewards calculation + distribution tools : some of our Delegates, such as InfinityStones, iotxplorer, and IoTASK, created open source tools to help Delegates calculate/distribute rewards and add transparency for voters

The IoTeX blockchain has held up very well!

Although Mainnet Rehearsal is now over, we will continue to strengthen and improve the IoTeX Network. We encourage ALL community members to test and help improve the IoTeX Mainnet once it is publicly launched.

Next Stop: Mainnet Alpha Launch!

The Mainnet Rehearsal was extremely useful in enhancing our consensus, adding usability for Delegates, and ensuring the real Mainnet can conquer all risks and scenarios. By going through this process, we are extremely confident that our Delegates will be able to grow and maintain the IoTeX Network.

The IoTeX blockchain code is currently being audited by top cybersecurity and formal verification companies. This process is similar to the audits of our staking/voting smart contracts by Certik & SlowMist. It is critical for the future of IoTeX that all security and performance issues are resolved before public Mainnet launch.

The blockchain audit is the final milestone before the public launch of Mainnet Alpha — we will announce to the community once this is completed. Assuming no issues, we plan to finalize and announce the official public Mainnet launch date during the week of April 15.

What else is on the horizon?

The Mainnet Alpha launch is coming soon, but there are also many other exciting things on the way! Some we can share now, and some are top secret to be shared soon. 2019 will be an amazing, action-packed year for IoTeX — here are some things to look forward to:
