On Friday, the IoTeX team announced via X that IoTeX v2.5.0 (Zanzibar Hardfork) is officially out. The hardfork is set to go live on October 19, and it is a massive protocol upgrade that moves staking rewards fully on-chain, tightens EVM precision, and lays the security groundwork for IoTeX’s next phase of scalability.
With this upgrade, staking yields are now 100% trustless and automated. The team designed this for a seamless transition—most Hermes-vault delegates with complete reward portions will migrate automatically at the fork block.
There will also be strict compliance with EIP-2200 dynamic gas rules. For developers and users, this prevents massive gas overcharging on certain in-place writes (saving 2,800 gas per hit). For indexers and wallets, token balance histories reconstructed from tx logs are now perfectly accurate.
The upgrade also completely closes the rogue-key forgery window today, safely paving the runway for IIP-52 signature aggregation (massive network scalability).
IoTeX's mission is to be a privacy-centric blockchain managing the entire information lifecycle of an Internet of Things (IoT) network, including data collection, transport, storage, and utilization.
IoTeX is the blockchain platform for Real-World AI. Since 2017, its foundational infrastructure has delivered verified, real-time data from the real world to AI systems and decentralized applications. Powering 100+ projects and 40M devices across mobility, robotics, energy, health, and more, IoTeX enables developers to build next-gen AI models and applications that deliver real-world impact.
The IoTeX tech stack provides the data, identity, and verification layers to fulfill the surging demand for real-world data in the new AI era:
-
IoTeX L1 — a secure, EVM-compatible blockchain with a Roll-DPoS consensus mechanism that settles transactions, coordinates participants, and distributes incentives.
-
ioID — a decentralized identity system that authenticates devices, AI agents, and data sources to ensure trust at the point of origin.
-
Quicksilver — a real-time data interface that verifies, indexes, and delivers structured physical-world data to AI models and applications.
-
IOTX token — the native digital asset used for transactions, staking, governance, and rewarding contributions to the network.
-
Trusted by partners like Google, Samsung, IEEE, ARM, and Nordic Semiconductor, IoTeX is uniquely positioned to capture the multi-trillion-dollar AI and data economy.
IOTX is up 0.5% today and is currently trading at $0.0036240.
