On October 21, 2025, the Kadena blockchain project officially announced that it is no longer able to continue business operations. The announcement was posted on Kadena’s official account on X (Twitter), stating that all business activities and active maintenance of the Kadena blockchain will soon be halted.
This move surprised the crypto community, given Kadena’s reputation as one of the Proof-of-Work (PoW) projects that achieved high scalability without sacrificing security and decentralization.

A Brief Overview of Kadena
Kadena is a Layer-1 blockchain founded by Stuart Popejoy and Will Martino, two figures who previously worked on blockchain projects at JPMorgan and in crypto research at the U.S. SEC. Through their flagship technology, Chainweb, Kadena attempts to solve the blockchain trilemma by maintaining security, decentralization, and scalability simultaneously. Its native token, KDA, is used for transactions and mining on the network. Prior to the shutdown announcement, Kadena was often praised for the energy efficiency of its PoW and for supporting smart contract and dApp development.

Contents of the Official Announcement
In their statement, the Kadena team expressed deep regret and thanked the community, internal team, and partners who supported their journey. The primary reason given for ceasing business was difficult market conditions and a lack of financial support to sustain long-term operations.
Although the organization is shutting down, the Kadena blockchain will continue to run as usual. As a decentralized network, independent nodes and miners will keep validating transactions without reliance on a central entity. The team said they will release a new binary that allows the blockchain to operate fully without Kadena’s organizational involvement. Node operators are urged to update their systems promptly to ensure network stability.

What Happens to the KDA Token?
According to the latest tokenomics data, more than 566 million KDA are still scheduled to be distributed as mining rewards through the year 2139. In addition, roughly 83.7 million KDA remain locked up until November 2029. This means that even if the Kadena entity ceases operations, the protocol and network will remain fully functional. Mining token distributions will continue as scheduled, and the community is now expected to take on greater roles in governance and ecosystem development.

Community Reaction and Future Impact
The news triggered emotional reactions across the crypto community. Some regret the decision, while others see it as a fresh start for Kadena to become fully community-driven. Given the decentralized nature of PoW, the Kadena network could continue operating like Bitcoin does, without needing a central organization to survive. However, the biggest challenges will be community coordination and funding for ongoing development. “The organization’s journey may have ended, but its technology and decentralized spirit will live on,” wrote one community member on X.

Conclusion
Kadena’s decision to stop business operations is a stark reminder to the crypto industry that true decentralization must be able to endure even without a central organization. The Kadena blockchain will remain alive through the community, miners, and developers who still believe in its vision. Although difficult, this also opens new opportunities: Kadena’s future is now truly in the hands of the community, in line with the original spirit of Web3.
