On March 30, 2026, the official detailed guide on the Nervos CKB halving mechanism was released. This is one of the most important events for long-term holders and miners.
How does CKB issuance work?
Nervos uses a unique dual-issuance model, unlike Bitcoin:
âą Primary (base) issuance â a limited supply of 33.6 billion CKB in total. This is the part that halves every ~4 years.
âą Secondary issuance â a constant 1.344 billion CKB per year, which supports miners and prevents the network from âdyingâ during low activity periods. Part of it is burned through state rent (state occupancy fees).
When is the next halving?
âą The second halving is expected in November 2027 (around November 19, at epoch 17,520).
âą Base issuance will be cut in half: from ~2.1 billion CKB per year down to 1.05 billion CKB.
âą Daily primary reward for miners will drop from approximately 5.75 million to 2.88 million CKB.
What does this mean in practice?
âą For miners: The reward decreases, but secondary issuance continues to operate. This makes the network more resilient â thereâs no risk of a sharp hashrate drop like in some other PoW projects. Only efficient miners will thrive.
âą For inflation: Overall emission rate will slow down. By 2027, real inflation will continue to decline, moving toward more deflationary levels as network usage grows.
âą For holders and the economy: Less new supply means potentially lower selling pressure from miners. Plus, the state rent mechanism encourages active use of CKB for data storage (not just âbuy and forgetâ).$BTC
Halvings will continue until approximately 2103, when the primary issuance is fully exhausted.
