The native token CKB of the Nervos Network does not have an absolute capped "total token supply." Its issuance adopts a dual-track mechanism: the base issuance has a hard cap of 33.6 billion tokens, while the secondary issuance has a fixed annual release of 1.344 billion tokens with no supply upper limit. Therefore, when discussing the total supply of CKB, it is necessary to distinguish between the base issuance hard cap, the genesis initial circulation, and the dynamic total supply.
CKB Total Supply: Hard Cap, Initial Circulation, and Dynamic Supply
- Base issuance total supply upper limit: 33.6 billion tokens.
- Genesis initial issuance: 33.6 billion tokens; among them, 25% (8.4 billion tokens) was burned, resulting in an initial circulating supply of 25.2 billion tokens.
- Secondary issuance: A fixed 1.344 billion tokens per year, with no hard cap.
- Dynamic total supply: Public statistics showed a range of approximately 42.9 billion to 49.8 billion tokens between late 2023 and 2026; this is a historical statistical range, and the latest figures should be subject to data from market platforms.
Base Issuance: Miner Incentives Similar to Bitcoin Halving
Base issuance is the primary source of rewards for PoW miners in the early stages of the CKB network, with a total supply capped at 33.6 billion tokens and decreasing by halving approximately every 4 years. The first halving was completed in November 2023. This design brings the early issuance pace closer to Bitcoin's supply model, while also providing miners with a relatively predictable incentive curve.
Secondary Issuance: State Rent and Capped-Free Release
Secondary issuance is another track of the Nervos economic model, releasing a fixed 1.344 billion tokens annually. It does not set a total supply hard cap, with the objective of providing a long-term funding source for on-chain storage occupation and miner incentives through a state-rent mechanism. As the base issuance gradually decreases, the secondary issuance assumes the role of supplementing miner revenue.
On-chain storage in CKB is related to token occupation: users need to hold or lock a certain amount of CKB to occupy on-chain storage space. Public data summarizes this relationship as on-chain storage space being pegged to the amount of CKB, with the common metric being 1 CKB corresponding to 1 byte of storage occupation. Consequently, network storage demand and token demand are bound together.
Inflation and Staking: The Role of Nervos DAO
Due to the ongoing secondary issuance, the total supply of CKB will increase over time. Nervos DAO provides a locked participation mechanism, allowing participants to receive compensation related to the secondary issuance to hedge against inflation dilution. It is not a price prediction tool, but rather a link in the Nervos economic model that connects storage occupation, miner incentives, and token supply.
How to Understand "How Much is the Total Supply"
If asked "What is the maximum amount of CKB that will ever be issued," the answer is that the base issuance has a hard cap of 33.6 billion tokens, but the secondary issuance has no hard cap, meaning there is no absolute total supply upper limit. If asked "What is the current circulating or total supply," this belongs to dynamic data and requires querying market platforms; public statistics showed a range of approximately 42.9 billion to 49.8 billion tokens between late 2023 and 2026, depending on the specific time and metric.
CKB can be traded on trading platforms that support the token.
