September 17, 2025 – ProBit Global, one of the leading cryptocurrency exchanges, has successfully completed the Polygon (POL) network hard fork. The major upgrade, finalized at 00:37 UTC (06:07 AM IST), is designed to make the Polygon network faster, more scalable, and more privacy-focused. Following the upgrade, deposits and withdrawals of POL tokens on ProBit Global were restored within hours.
This hard fork is part of Polygon’s broader roadmap to enhance system performance, introducing advanced technology that strengthens both speed and security.
What Is zkRollup Technology?
At the core of the upgrade is zkRollup (Zero-Knowledge Rollup) technology. Instead of processing every transaction individually on Ethereum, zkRollups bundle multiple transactions together and record them as a single entry. This significantly reduces costs and improves efficiency.
More importantly, zkRollups leverage cryptographic proofs to protect user data, ensuring privacy without compromising security. According to Chainlink reports, zkRollups are rapidly becoming one of the most important innovations in modern blockchain ecosystems.
The POL Token
Polygon’s native token, POL, plays a crucial role in the network’s ecosystem. As of September 2025, 10.5 billion POL tokens were in circulation. With the new upgrade, POL holders can now stake their tokens, supporting network operations while earning rewards in return.
Polygon is also expanding its presence in decentralized finance (DeFi) and non-fungible tokens (NFTs). With improved scalability and lower transaction costs, the network is set to attract more applications and users.
ProBit Global’s Role in the Upgrade
ProBit Global ensured a smooth transition by quickly restoring POL deposits and withdrawals after the hard fork. The exchange, which supports over 800 altcoins and 1,000 markets, now allows users to trade POL against top assets such as USDT and BTC. Clear guidelines were also published to help users adapt to the updated system.
By promptly integrating the upgrade, ProBit Global reinforced its reputation as a forward-looking exchange that embraces cutting-edge blockchain solutions.
Industry Outlook
The Polygon hard fork highlights a growing trend in the crypto market toward advanced solutions like zkRollups. Earlier in 2025, other major exchanges such as Bybit also upgraded their Polygon support. According to industry data, around 26% of existing Ethereum Layer 2 projects already utilize Zero-Knowledge technology.
This shift underscores increasing demand for scalability and privacy within the blockchain space. For developers and users alike, the Polygon upgrade signals stronger adoption and wider opportunities in the DeFi and NFT sectors.
