How To Stake?

Stake:

U2U uses a Delegated Proof-of-Stake consensus algorithm to validate transactions and secure the network. You can participate by staking your U2U Token. In exchange, you are rewarded with U2U Token and you can unstaked your tokens at anytime.

Max Lock Duration must be equal or lower than Validator Lock Duration

Lock:

After delegate your tokens to staking, you can join the lock package to increase your reward while staking. The minimum lock-up periods is 14 days and the maximum is 365 days. Your tokens will be transfer back to Stake stage when your lock-up period end. You can also unlock your token before the lock-up period end. However, you will pay a penalty for doing so. Since your rewards are always unlocked and withdrawable, the penalty will come from your staked amount. If you unlock earlier, regardless of how much of the lock-up period is left, you will only receive half of the base rewards; the additional rewards will be burned.

Validator running the node need to lock to allowed the Delegator to lock.

Max Lock duration of Delegator must equal or smaller compare to Validator Locked amount.

Staking parameters

Minimum amount: 1 U2U
Maximum amount: 10 times of the validator self-stake. If the validator stakes 1M U2U, then the max delegation amount that a delegator can stake is 10M U2U
Minimum stake period: 0 days
Minimum lock-up period: 14 days, earning the base reward rate
Maximum lock-up period: 365 days, earning the maximum reward rate
Unbonding time (time between undelegate and funds becoming available): 21 minutes or 3 epoch, depending on which conditions come first.
Delegation fee: The network has set a fixed fee of 15% on staking rewards paid from stakers to validators for operating their nodes
Burn Fee Share: 5%, our deflation mechanism for staking
Treasury Fee Share: 20%, will be transfer to Unicorn Ultra Treasury & will be announce to community how we use it in the future
Validator commission: 15%, the commission fee in percentage a validator will get from a delegation. This fixed fee is paid from delegators to validators for running their nodes. For example if you earn 25% on a stake of 1,000,000 U2U, you'll receive 1,000,000 * 0.25 * (1-0.15) = 212500 U2U per year.
Base staking reward per second: ~3.8 U2U
Offline penalty threshold blocks: 1000 blocks, the number of offline blocks required to mark a validator as offline
Offline penalty threshold time: 5 days, the time required to mark a validator as offline
