描述BENZ is created for powering the IronGeekChain; all transaction, voting and smart contract deployment fee will be charged in BENZ. BENZ can be acquired by staking EagleX. The EagleX holder just need to hold their EagleX in its wallet and will get BENZ without need to turning on the network, therefore, it is called cold staking. Maximum total supply of BENZ is 144 million with 2 decimals which will be reached in 10 years. The BENZ generated for the first year is 64 million BENZ, then 32 million, 16 million, 8 million, and 4 million BENZ per year until reach maximum total supply. There is no pre-mined BENZ at the beginning. The use of BENZ for smart contract deployment and transaction fee will make BENZ price sustainable.
