Unlike Base Issuance, Secondary Issuance is not distributed to everyone on the network, but rather targeted at users who occupy space on Nervos or hold their CKBytes outside of Nervos DAO. The CKBytes from Secondary Issuance are used to collect state rent and are distributed to miners who maintain the network (State Rent), Nervos DAO users, and the Nervos Treasury. CKBytes holders can lock their tokens in Nervos DAO to gain interest in a similar manner to staking on other platforms, which offsets the long-term inflationary effects of Secondary Issuance exactly, resulting in no loss of value over time.",
