Record Player NFT

What is Record Player?

A Record Player in Sonorus is an NFT that allows users to host their records and earn rewards. Users have to hold at least one record players to start earning.

Where to get a Record Player?

There are three ways for users to obtain a new record player:

• Users can use their $RUS to generate new record players through build

• Users can purchase record players from Sonorus' in-app marketplace (currently under development)

• Users can generate new record players from old ones using $RUS through forge (currently under development)

Record Player Attributes

Levels

The levels of Record Player NFTs decide the number of music copies each Record Player NFT can host. In general, the higher the level of a Record Player, the more music copies it can host.

Record Player UpgradesUsers can upgrade their Record Player NFTs with $RUS tokens to achieve higher levels. The following table lists the current amount of $RUS tokens required to upgrade at each level. Please note that upgrade costs are subject to periodic adjustments to maintain sustainability of Sonorus tokenomics.

Record Player Level	Copy Capacity	Upgrade Cost
Level 1	10	700 RUS
Level 2	50	1500 RUS
Level 3	100	7500 RUS
Level 4	500	14000 RUS
Level 5	1000	25000 RUS
Level 6	2000

Battery Life

Users can only earn $RUS yield if their record players has battery remaining. When a record player runs out of battery, it is deemed inactive. Users can still listen to their purchased tracks, but they will not be eligible for any Sonorus rewards mechanisms.

Each record player has a battery life of 7 days. The battery life only decreases when the record player is in use.

Users can recharge their record players using their $RUS tokens. Every time a Record Player is recharged, the battery of the Record Player is restored to full. As listed in the table below, the higher the level of a Record Player, the more $RUS tokens it needs to recharge its battery. Please note that recharge costs are also subject to periodic adjustments to maintain sustainability of Sonorus tokenomics.

Record Player Level	Recharge Cost
Level 1	105 RUS
Level 2	525 RUS
Level 3	1050 RUS
Level 4	5250 RUS
Level 5	10500 RUS
Level 6	21000 RUS

The unit of the active period is a "day," which equals 24 hours. For example, if a user recharges their record player at 1 pm today, the record player will become inactive at 1 pm seven days later. Each time a user recharges their record player, the active period will reset, and the remaining active period will be lost. For instance, if a user recharges their record player at 1 pm on day 1 and recharges it again at 10 am on day 7, the new expiration time will be 10 am on day 14, instead of 1 pm on day 15.

In Use vs Available

Every record, regardless of the number of copies a user has purchased, occupies a single record player. A record player is marked as "In Use" when a track occupies it; otherwise, it is marked as "Available." Users can insert newly purchased tracks into available record players.

For more available record players, users can choose to:

• Build, purchase, or forge new record players

• Upgrade their record players to increase the record capacity.
