The solaghosts that are buried in a plot with a gravestone, will reward their holders with the $BOO. This token can be used to buy land, upgrade gravestones, or give offerings to your Solaghosts for ever better rewards.
Each land has its own cemetery, which will has a number of parcels owned or for sale (you will be able to buy the cemetery plots here or in secondary markets).
A certain number of gravestones can be placed on each plot for a Solaghost to rest. Parcel owners will receive a percentage of the rewards from each grave in their parcel. Also, each plot and gravestone space has its address (e.g. solaghosts.io/gravestone1234), which will shows the address of its owner's wallet and part of Solagea's history. More of this in the Lore.
Each Solaghost holder may decide to bury his Solaghost in any of the available slots in the different plots of the Solaghosts universe, to make staking and receive $BOO as a reward.
To earn a higher % of rewards in staking, each holder must buy tombstones and assets such as flowers, water, etc. All of this can be purchased with the $BOO Token.
