Every time a user Mints ZONE on Twilight ZONE, he is actually purchasing a bond. This Bonds have different parameters. The BCV allows us to scale the rate at which bond premiums increase. A higher BCV means a lower discount for bonders and more protocol profit. A lower BCV means a higher discount for bonders and less protocol profit. The vesting term determines how long it takes for bonds to become fully redeemable. A longer term means lower inflation and lower bond demand.
