When you defeat the dragon in singleplayer, you acquire a unique trophy in the form of its egg. You cannot obtain a second one like it, but the one already in your inventory belongs to you and no one else. However, everything changes as soon as you join a multiplayer game:

Down with this communist nonsense! Welcome to the age of capitalism!
One of the simplest solutions to the problem would be to eliminate the "egg limit," allowing a new egg to appear after each re-summoned dragon is killed. Unlimited dragon eggs, yeah. But this way, the egg ceases to be unique and valuable.
This mod approaches the issue from a different angle: each person who kills their first dragon will receive their own egg. So, the trophy is unique to each player, not for the entire server.
