- Hayabusa Upgrade Brings DPoS and Staking Changes
- Network Implications and Community Participation
- VeChain transitions to DPoS, allowing VET holders to stake and delegate for network security.
- VTHO issuance pauses at hard fork, resuming as dynamic block rewards tied to staking.
- KuCoin suspends VET deposits and withdrawals on Dec 2, but trading remains active.
- Hayabusa introduces validator lifecycle overhaul and gas optimizations for improved performance.
VeChain is preparing for its most ambitious network upgrade since mainnet, the Hayabusa hard fork. Scheduled for December 2, 2025, the upgrade will introduce a new Delegated Proof of Stake model, updated tokenomics, and enhanced validator operations.
Deposits and withdrawals of $VET will be temporarily suspended on major exchanges, including KuCoin, to accommodate the transition. Trading, however, will continue uninterrupted while the network shifts to the new consensus and reward mechanisms.
Hayabusa Upgrade Brings DPoS and Staking Changes
The Hayabusa upgrade marks VeChain’s transition from Proof of Authority to Delegated Proof of Stake (DPoS), expanding community participation. VET holders can now stake or delegate tokens to directly influence network security, according to official VeChain sources.
Validator lifecycle management has been overhauled, with staking, delegation, renewal, exit, and withdrawal handled through a new Staker contract. Stake-weighted finality will ensure blocks finalize based on validator weight, increasing cryptoeconomic resilience.
Dynamic VTHO issuance replaces static generation, adjusting rewards based on network activity and staked supply. VTHO token generation will pause at the hard fork block, resuming as staking-based block rewards afterward.
Developers gain enhanced tooling, including improved error context, new admin APIs, and full Devnet mirroring. Performance optimizations target gas usage, storage efficiency, and general network stability.
The testnet hard fork completed successfully on November 4, 2025, providing a blueprint for the mainnet upgrade. KuCoin confirmed VET deposits and withdrawals will be suspended from 10:00 UTC on December 2, ahead of the scheduled 11:27 UTC hard fork.
Exchanges caution users to avoid moving VET during the upgrade window to prevent transaction failures.
Network Implications and Community Participation
The transition positions VeChain for broader decentralization while aligning incentives between validators and token holders.
By enabling stake-based participation, the network expects higher engagement from the VET community. The update also supports scalable governance structures, giving stakeholders a more direct role in network security.
Gas optimizations and validator enhancements aim to reduce costs and improve block finality speed, reinforcing network reliability. The Hayabusa upgrade retains VET’s current supply, with no new tokens issued.
Major exchanges like KuCoin have confirmed that trading remains active, minimizing disruption for market participants.
VeChain’s naming of the upgrade after the Japanese Hayabusa spacecraft reflects its focus on precision, innovation, and network endurance. The hard fork represents a critical milestone as the blockchain evolves toward a fully delegated and performance-optimized system.
