# Glow Lotto Parameters

There are several Glow Lotto parameters that can be modified by the Governance. The polls voting over these parameters will be activated after the first 6 months of Glow, following our progressive decentralization roadmap.

#### Modify Split Factor

`Split Factor` determines what percentage of the yield generated by a user's deposit accrues to the lottery pot and what percentage is used as direct yield for the user.

Genesis value is 0.75, meaning 75% of the yield goes to the lottery.

#### Modify Reserve Factor

`Reserve Factor` determines the commission fee that the protocol takes out of the distributed prizes in the lottery.

Genesis value is 0.05, meaning that 5% of each prize will be redirected to the Glow reserve and the re-distributed pro-rata among GLOW stakers.

#### Modify Instant Withdrawal Fee

The Glow Lottery has several measures to ensure its fairness\[link]. One of these measures is the Instant Withdrawal Fee. When a user wants to withdraw its deposits, they normally need to wait for the `Unbonding Period` , which is normally the same as one `Lottery Interval`.

If the user has unexpected urgency in redeeming its deposits, Glow offers an alternative, incurring the `Instant Withdrawal Fee` . The Genesis value is 0.1, meaning that a 10% commission will be applied to instant withdrawals. It should be noted that this value should be relevant, to ensure safety and fairness against a whale that could try to game the protocol.

#### Modify Unbonding Period

As mentioned above, standard withdrawals must take into account the`Unbonding Period`time. This is a sensitive parameter, and should always be equal to or larger than the `Lottery Interval`

#### Modify Ticket Prize

In Glow, each time you make a deposit over a certain threshold you get free, recurring tickets for the Weekly Lottery. The amount of tickets a user receives given the deposit amount is determined by the `Ticket Prize` 

The genesis value of `Ticket Prize` is 10 UST, meaning that each 10 UST worth of deposit a user would get a lottery ticket. As an example, a deposit of 72 UST would reward the depositor with 7 tickets.

#### Modify Lottery Interval

The Glow Lottery is executed periodically and this interval can be modified by the community. The standard`Lottery Interval`is set to one week. As a principle, this parameter should be only modified if there are strong reasons to.

#### Modify Prize Distribution

The Weekly Lottery winning number is composed of 5 digits. The `Prize Distribution` is an array of 5 elements, that maps the number of number hits and the prize percentage to be split.

An example would be \[50,30,15,5,0,0]. Hence, all the players that have a ticket with 4 numbers in the same position as the winning ticket would split 30% of the total available pot.

The `Prize Distribution` elements must add up to 100.

**Modify Round Delta**

The round delta determines the number of rounds after which the next randomness will be queried to run the lottery. This is a sensitive parameter and should only be changed in special situations.

**Modify Block Time**

The block time determines the number of blocks where the lottery will be blocked while being executed. This is a sensitive parameter and should only be changed in special situations.
