The main building block of the Kira economy is KEX which is a native staking asset of the Kira Network. Basically staking KEX is the most efficient way of claiming revenues from the protocol operations, such as block and fee rewards. KEX holders have the ability to become part of the governance and the validator set of the Kira Network. Kira’s governance has then the ability to define interest rates for staking foreign tokens which in turn increases security and liquidity of our exchange protocol. And KEX acts as a reserve currency in terms of which staking all other assets is valued. So it’s a governance that ensures that staking KEX is not only the most profitable in comparison to other tokens but also attracts other token holders and increases network activity. Of course you are free to stake any asset like btc, eth, atoms and so on and earn revenue on that but staking KEX will give you more rewards.
