IoTeX Roll Dice Campaign — (Now Closed)

The Roll Dice Campaign has officially come to a close! Thank you to everyone who participated. We hope the odds were in your favor and that you earned some IOTX points while gaining a deeper understanding of Testnet Alpha: Strive and our in-house Roll-DPoS consensus mechanism! We greatly appreciate the community’s support and patience with the technical difficulties experienced within the first day of the campaign. The IoTeX team was quick to respond and to tend to any issues that arose. Thank you for all the feedback submitted! We strive to further improve and deliver fun/seamless campaigns to engage with you all more in the future.

Here are the correct answers to to our Roll Dice Campaign:

Q1: How many block producers (i.e., delegates, “master nodes” will there be in the IoTeX network?

It is auto-scalable based on the # of sub-chains.

Reference: yellow paper and infographic

Q2: How can someone become a block producer (BP) candidate in the IoTeX network?

BP candidates are chosen through a voting process by token holders.

Reference: yellow paper and infographic

Q3: Which other blockchain projects use variants of delegated proof of stake (DPoS) consensus mechanisms?

EOS, Lisk, Tezos.

Reference: yellow paper and infographic

Q4: What lightweight IoT devices did IoTeX demo their Testnet Alpha code running on?

Raspberry Pi, VoCore2 router, Pocket Beagle.

Reference: Testnet Alpha video

Q5: How many candidate nodes and block producer (delegates) nodes are there in the Testnet?

21 candidates, 7 block producers.

Reference: Testnet Alpha video

Q6: How often are new block producers (delegates) chosen in the IoTeX network?

Every epoch.

Reference: yellow paper, infographic, Testnet Alpha video

Q7: What is the process for a token holder to become a block producer (delegate)?

Self-nomination, voting process to define candidate pool, random selection of block producers from candidate pool.

Reference: yellow paper and infographic

Q8: Which “core component” does IoTeX use in its Roll-DPoS consensus mechanism?

Practical Byzantine Fault Tolerance (PBFT) with instant finality

Reference: yellow paper, infographic

Q9: Which of these metrics related to the current Testnet run is NOT an element of the IoTeX Explorer?

Latency (in seconds).

Reference: Testnet Alpha video

Q10: Why did IoTeX choose to enhance the traditional DPoS consensus mechanism and create Roll-DPoS?

DPoS can be improved to support complex blockchain architectures and large-scale IoT systems.
