Deep Dive
1. Hayabusa Consensus & Tokenomics Upgrade (December 2025)
Overview: This was a major protocol overhaul, moving VeChainThor from a Proof-of-Authority to a public, permissionless Delegated-Proof-of-Stake (DPoS) consensus. For users, this means a more open network where staking VET is the primary way to earn rewards from transaction fees.
The "Hayabusa" upgrade, part of the VeChain Renaissance roadmap, fundamentally changed the network's economic security and reward distribution. All rewards from the gas token (VTHO) are now allocated exclusively to those who stake VET, aiming to increase individual yields and create a more deflationary pressure on VTHO by reducing idle supply.
What this means: This is bullish for VET because it incentivizes long-term holding and participation, which can reduce sell pressure and increase network security. For everyday users, it means a clearer way to earn passive income by staking their tokens.

2. Network Upgrade & Hard Fork Support (December 2025)
Overview: Exchanges like LBank announced support for a VeChain network upgrade and hard fork, a coordinated update to the core protocol that required temporary pauses in deposits and withdrawals.
This type of upgrade typically includes bug fixes, performance optimizations, and the implementation of new features agreed upon by the community. It is a mandatory update for all node operators to ensure network continuity and stability.
What this means: This is neutral for VET as it represents essential maintenance and progression. For users, it ensures a more reliable and up-to-date network, though it requires no direct action unless they are running a node.

3. Thor Block Gas Limit Increase (April 2024)
Overview: An update to the VeChainThor client increased the block gas limit from 30 million to 40 million, allowing more transactions to be processed per block and improving overall network throughput.
The update, labeled Thor v2.1.1, also refactored the public API to improve developer experience and included various dependency updates and code refactors. Authority Masternodes and public nodes were urged to upgrade to this version.
What this means: This is bullish for VET because a higher capacity network can support more users and applications without congestion, leading to a better experience and fostering growth. It's a foundational upgrade for scaling.

Conclusion
VeChain's development trajectory is defined by substantive protocol upgrades that enhance scalability, economic incentives, and network participation. The shift to DPoS with the Hayabusa upgrade marks a pivotal move toward a more decentralized and stakeholder-aligned ecosystem. How will the increased staking participation influence VET's circulating supply dynamics in the coming months?
