3 min readNov 21, 2023


Greetings, Starfam! 👋

We’re upping the ante in the world of blockchain innovation!

Welcome to the Phase II Testnet of FlexiDAG in Starcoin 2.0: Unleash the Future 🎉

If you were intrigued by our previous blockchain advancements, get ready for something even more groundbreaking!

Your feedback and support have been invaluable in refining the Starcoin 2.0 ecosystem, and now it’s time to unveil the extraordinary FlexiDAG.

FlexiDAG is the latest jewel in the Starcoin 2.0 crown, and it promises to transform the way we experience blockchain technology. Let’s delve into the five core advantages that make FlexiDAG the future of blockchain:

  1. Enhanced Performance
    FlexiDAG is designed to elevate the performance of Starcoin 2.0 to new heights. By marrying the directed acyclic graph (DAG) structure with Satoshi Nakamoto’s enhanced proof-of-work consensus, we’ve catapulted the system’s throughput and efficiency to unprecedented levels.
  2. Parallel Block Generation
    Say goodbye to sluggish transaction confirmations. FlexiDAG introduces parallel block generation, allowing multiple blocks to be created and added to the blockchain simultaneously. This translates to lightning-fast transactions, reduced latency, and near-instant confirmation times — ideal for high transaction volumes and rapid confirmations.
  3. Uncle Blocks No More
    FlexiDAG brings a revolutionary consensus protocol that eliminates the concept of uncle blocks. Previously discarded competing blocks now have the opportunity to become valid blocks, maximizing mining power utilization and overall efficiency.
  4. Adaptive to Real Network Conditions
    FlexiDAG is designed to thrive in ever-changing network conditions. It dynamically adjusts block generation times and other consensus parameters based on network congestion, ensuring stability and peak performance during increased on-chain activity.
  5. Unprecedented Transaction Speeds
    With FlexiDAG, Starcoin 2.0 is positioned to set new standards in transaction speed. Get ready for a blockchain experience that’s faster and more efficient than ever before!

But here’s the most exciting part — you don’t have to wait to experience FlexiDAG. You can actively participate in our FlexiDAG Testnet Campaign and be among the first to witness the future of blockchain.

Your feedback is not only valuable; it’s essential in shaping the progress of FlexiDAG and Starcoin 2.0. Your insights can earn you rewards and play a pivotal role in the evolution of blockchain technology.

Don’t let this opportunity pass you by. Join us in the blockchain revolution, and explore FlexiDAG today!

Together, we’ll pave the way for a faster, more efficient, and more adaptable blockchain future. Get ready to make your mark in the FlexiDAG revolution! 🚀

  1. Unlimited Runtime: Participants can enter FlexiDAG Pre-mining at any time during the activity period.
    (Mining duration is not a prerequisite for rewards.)
  2. Original User Weighting Mechanism: In order to encourage greater participation from long-term users with active mainnet addresses (and normal balances), the weighting of rewards increases with the duration of activation for these users.

Participation Steps:
Run FlexiDAG Pre-mining to experience the Starcoin 2.0 upgrade Pre-mining process.
Try to use existing addresses for mining participation
To ensure fairness, users generating a significant number of addresses in a short period will be excluded from reward distribution.

Lucky Draw Time: Rewards will be drawn and distributed within 5 days after the end of the activity.

“The official Twitter account @StarcoinSTC reserves the final interpretation right for activity rewards.”
