Kadena (KDA) ceases operations: impact on ASIC miners (Antminer KA3) and what comes next

On October 21–22, 2025, the team/project Kadena announcedcessation of its operations (organizational shutdown). The blockchain remains online and secured by the miners and the community, but without a central team in charge. Following this, the KDA token has fallen by ~50–60% according to crypto news platforms.^[1–4]

What has been announced (and what it means)

• Cessation of activities of the Kadena organization (foundation/team): no more central management, end of official operational support.^[1][3][4]
• The Kadena channel continues : Proof-of-Work network maintained by minors And community developersTransition towards “community-run” governance.^[1][2][3]
• Extreme volatility of KDA : drop of -50 to -60% after the announcement (according to the media followed).^[2][4]

Operational translation: there blockchain is not stoppedHowever, there is no longer a central entity to coordinate development, communication, and certain ecosystem services. The future will depend on the community, miners, pools and exchanges.

Consequences for Kadena ASIC miners (Antminer KA3)

1) Mining technically "continues"

As long as it exists pools, nodes, and miners who validate blocks, the chain remains active. Your KA3 can therefore always submit shares and collect KDA payouts (if the pool remains operational).^[1][3]

2) Risks to monitor

• KDA Award : if the fall continues, the KING may become uncertain or negative.
• Network difficulty & hashrate : could decrease (departures of miners) or fluctuate sharply.
• Ecosystem support : some pools/exchanges/wallets may modify, suspend or strengthen their policies.
• Liquidity : wider spreads, increased slippage on KDA during periods of uncertainty.

3) What you can do right away

• Check your pool : EU/US server status, official announcements, thresholds and payment frequency.
• Activate multiple endpoints (primary + 2 backups) to avoid interruptions if a server fails.
• Monitor your KPIs Effective hashrate (pool vs. local), rejection rate, network stability, payouts and confirmed.
• Set a stopping threshold : if "electricity cost/day > income/day" for X days, break or a change of strategy.
• Alternative payouts (if available): some pools/marketplaces offer auto-convert in BTC/USDT; check fees & risks.

Short and medium-term scenarios

Scenario A – Community Continuity

The chain remains mined, of the clients/nodes are maintained by the community, the ecosystem reorganizes itself. Mining continues, but with a risk premium (KDA price, services, com').^[1][3]

Scenario B – Ecosystem contraction

Sustained drop in price and liquidity, closure of some services. Miners optimize (cheaper electricity, undervoltage) or se withdraw if not profitable.

Scenario C – Relaunch/Transition

A community team or third-party actors resume developmentrestoring visibility. Mining remains viable if on-chain usage/activity picks up again.

Sustainability checklist (KA3)

• Electricity cost : (3.15 kW × kWh price × 24 h) → compare to KDA/day income.
• Optimization stable firmware, ventilation cleaning undervolt/underclock moderate if necessary.
• Plan B : resale of the equipment (secondary market) if the KDA thesis no longer suits you.
• Risks : keep a treasury to absorb volatility and adjustment delays.

FAQ rapide

Q: Will my KA3 become unusable?
A: No, not automatically. The continuous chain if miners/pools remain active. The question is economic (KDA price, fees, electricity).

Q: Do mining rewards stop?
R: No, the rewards planning is coded on-chain. They continue as long as the chain is running. payouts depend on your pool.^[3]

Q: Should I turn off my miner?
A: Establish a target threshold If (income < electricity cost) for X consecutive days → pause/adjustment. Stay tuned for announcements from pools/exchanges.

Conclusion Minent.fr

The cessation of operations by the Kadena organization changes the governance and the risk profile, but does not stop the blockchain as long as miners and nodes remain online. For holders ofAntminer KA3The decision is first economic Monitor KDA prices, costs, and service stability. Prepare a strategy flexible (optimization, pause, resale) depending on developments in the coming weeks.
