Assuming a scenario where a validator exhibits Byzantine fault characteristics and double-signs a block on the ZenChain network, what cascading effects are most likely to occur considering the CLCM's incentive structures and slashing mechanisms?
- The validator and their nominators are subject to slashing, a portion of their staked ZCX is redistributed to other validators with exemplary performance, and the validator faces a temporary ban from participating in block production.
- Only the validator is subject to slashing, while nominators are given the option to unbond immediately without penalty; the slashed ZCX is used to fund network development initiatives, and the validator is permanently blacklisted from ZenChain participation.
- The validator is immediately removed from the active set, nominators receive a proportional increase in their staked ZCX as compensation, and the slashed ZCX is burned, increasing scarcity.
- The validator and their nominators are subject to slashing, resulting in a reduction of their staked ZCX; the slashed ZCX is deposited into a governance-controlled pool, and the validator's reputation score is severely penalized, affecting future election chances. (correct)
Within the ZenChain's election process leveraging Phragmen's Election Algorithm, what considerations must a prospective validator strategically prioritize to optimize their selection probability, assuming rational nominator behavior under conditions of imperfect information regarding validator operational security?

- Maintaining a low total stake relative to other validators while offering consistently high reward payouts to attract 'whale' nominators seeking maximum returns.
- Implementing robust operational security measures and transparently communicating these to potential nominators to build trust and mitigate risk perceptions. (correct)
- Maximizing total staked ZCX, irrespective of the number of nominators, to project an image of network dominance and deter potential attacks.
- Cultivating a broad base of nominators, even with smaller individual stake amounts, to demonstrate widespread community support and resilience against Sybil attacks.
Considering the time-based structure of ZenChain, what implications arise from unclaimed staking rewards after the 84-era (21-day) deadline, and how does this affect overall network economics and participant behavior?
Considering the time-based structure of ZenChain, what implications arise from unclaimed staking rewards after the 84-era (21-day) deadline, and how does this affect overall network economics and participant behavior?
- Unclaimed rewards are transferred to a community-managed treasury, to be used for funding ecosystem development projects and incentivizing new users to join the network.
- Unclaimed rewards are burned, reducing the total ZCX supply and creating deflationary pressure, thus incentivizing active reward claiming and participation. (correct)
- Unclaimed rewards are automatically re-staked to the validator responsible for generating those rewards, compounding their stake and incentivizing continued block production.
- Unclaimed rewards are redistributed proportionally among active nominators who have claimed their rewards, incentivizing timely claiming and increasing the yield for active participants.

Study Notes
- Staking is essential to ZenChain's Cross-Liquidity Consensus Mechanism (CLCM), involving locking ZCX to enhance network security and governance.
- Staking motivates participants through rewards and aligns validators and nominators with the network's goals
Eras
- Eras are fixed periods of time, usually 6 hours long, during which validators create blocks and finalize transactions.
- Validator performance is reviewed, and rewards/penalties are calculated at the end of each era.
- Rewards are given to validators and nominators based on how well they did and what they contributed.
- Eras offer a regular schedule for assessing validator behavior, maintaining consistent incentives and penalties to ensure network security and integrity.
Sessions
- Sessions are shorter intervals within an era, with each era typically consisting of 6 sessions.
- Each session lasts approximately 1 hour, during which validators take turns producing blocks and participating in consensus activities.
- Sessions allow for continuous evaluation and adjustment of the validator set, enhancing the network's resilience and adaptability.
- Validators are rotated across sessions, providing multiple opportunities to validate and produce blocks, thereby contributing to the overall network health and stability.
- The results of these sessions collectively determine the validator's performance for the era, influencing the distribution of rewards and any penalties applied.
Bonding
- Bonding involves validators and nominators locking up their ZCX tokens to participate in staking.
- Bonded tokens act as collateral to support network security and can earn rewards based on validator performance.
- Exposure involves actively participating in the network's consensus mechanism by validating blocks or nominating validators.
- Staked tokens remain locked and cannot be freely transferred or traded until they are unbonded.
- To participate in consensus by becoming a nominator or validator, you must have a minimum amount of ZCX staked.
Unbonding
- Unbonding allows participants to withdraw staked tokens from the network.
- The unbonding process takes two eras to complete, during which tokens remain locked.
- After requesting to unstake, participants must wait for the bonding period to end before withdrawing funds.
- The unbonding period secures the network by preventing participants from immediately withdrawing their stake and acting maliciously.
- Staked currency that is not "exposed" in the current era can be unstaked without waiting for the full bonding duration.
- Being "exposed" includes earning rewards or being at risk of penalties with a validator.
- Fast unstake requires a deposit of 1 Gwei ZCX, which is forfeited if the request is made without eligibility.
Validators
- Validators produce blocks, validate transactions, and participate in consensus to secure the ZenChain network.
- Becoming a validator requires bonding a significant amount of ZCX tokens and election through the network's process
- Rewards are earned according to performance and stake, but can be slashed for failures or malicious actions.
Nominators
- Nominators delegate their stake to validators to support network security, earning a share of the rewards.
- Nominators are incentivized to choose reliable validators to maximize rewards and minimize slashing risks.
- Nominators are also incentivized to back validators with lower total support to maximize their share of staking rewards
Staking System
- The staking system incentivizes participation, decentralization, and network security.
- Nominators select validator targets, but the system assigns backing to a subset determined by the election process each era.
Chilling
- Chilling allows validators or nominators to temporarily pause staking activities without unbonding tokens.
- Useful for avoiding slashing risks without losing a staked position.
Staking Rewards
- Staking rewards are given at the end of each era based on validator performance and stake.
- Validators are rewarded for producing blocks and participating in consensus
- Nominators receive a share of the rewards based on the validators they support
- Rewards are intended to incentivize honest and reliable network participation.
- Rewards must be claimed within 84 eras (21 days), or they are lost.
- Rewards are stored in pages, with up to 64 nominators' rewards on each page.
- Claiming a page distributes rewards for all nominators on that page.
- Validators are incentivized to claim their associated pages and help distribute rewards to their nominators.
Slashing
- Slashing is a penalty for malicious behavior or poor validator performance.
- Validators and nominators can lose staked tokens for actions like double-signing blocks or failing to validate transactions.
- It deters misconduct and ensures network integrity.
Validator Selection
- ZenChain uses Phragmen's Election Algorithm to select validators each era.
- This algorithm ensures a fair distribution of stake
- The election process happens at the beginning of each era, using each validator's total stake to determine the validator set.
- The election process is a multi-phase system
- Submitting a solution is equivalent to counting votes that have been cast by stakers
- The computation can be done off-chain with tools like the Polkadot Staking Miner.
