â¨Lucky Lucky
Each day, there is a special round of Lucky Lucky, in which we give one lucky participating board member a special prize ( of all reward emissions per day, which is 138,240 BUTTERs based on current emission rate).
You can stake any number of BOARD tokens to in the Lucky Lucky, pool and your BOARD tokens will be returned in full amount if you leave Lucky Lucky. If you keep the staked BOARD tokens in Lucky Lucky pools without unstaking, you will automatically participate each round of Lucky Lucky.
Winning probability, what we name it power, is determined by both the number of staked BOARD tokens and the staking timing. If you have not staked any BOARD tokens before the current round of Lucky Lucky starts, the initial power is set to 0. If you have already staked some BOARD tokens before the current round of Lucky Lucky starts, the initial power is given as follows:
board_current is the current number of BOARD tokens you have already staked, end_block is the predicted end block number of this round of Lucky Lucky, and start_block is the start block number.
During the day, you can stake and unstake freely any mount of BOARD tokens to Lucky Lucky event.
Each time you stake BOARD tokens to Lucky Lucky event, the power is updated as follows:
board_num is the number of BOARD tokens you stake this time, end_block is the predicted end block number of this round of Lucky Lucky, and current_block is the current block number.
Each time you unstake BOARD tokens from Lucky Lucky event, the power is updated as follows:
board_total is the number of staked BOARD tokens before this unstaking, and board_num is the number of BOARD tokens to be unstaked.
By the end of day, the smart contract will calculate a power value for each participants. And a weighted random selection based on the power value will be used to select the winner for the Lucky Lucky event.
Everything is calculated inside smart contracts on blockchain, and we believe it is a fair and fun event to participate.
