Ethereum News Today: Google Cloud Challenges Ethereum with Neutral Blockchain for Global Finance

Google Cloud is progressing with its initiative to develop a Layer 1 (L1) blockchain, the Google Cloud Universal Ledger (GCUL), which is designed as a neutral and institutional-grade infrastructure for financial markets. The platform is being positioned as a high-performance, credibly neutral blockchain specifically tailored for institutions. GCUL supports Python-based smart contracts, aiming to enhance accessibility for developers and financial engineers, according to Rich Widmann, Global Head of Strategy for web3 at Google Cloud [1].

The Universal Ledger is intended to serve as a shared infrastructure layer rather than being tied to a single payments ecosystem. Unlike Stripe’s Tempo, which is deeply integrated with its existing merchant payment infrastructure, or Circle’s Arc, which centers around USDC as its native fuel, GCUL is designed to be accessible to any financial institution without favoring a particular competitor [2]. Google emphasizes the neutrality of its platform, arguing that institutions like Tether or Adyen may be reluctant to use blockchains controlled by their rivals, while GCUL is open to all [3].

Google and CME Group have already completed the first phase of integration and testing for GCUL. The CME Group has described the technology as a potential breakthrough for collateral, settlement, and fee payments in markets transitioning to 24/7 trading [4]. According to the March announcement, testing with market participants is set to begin later in the year, with full services expected by 2026 [5]. In contrast, Circle has already begun piloting its Arc blockchain, while Stripe plans to launch Tempo next year [6].

GCUL’s differentiation lies in its focus on Python-based smart contracts and institutional-grade tokenization. Stripe’s Tempo emphasizes merchant integration, and Circle’s Arc highlights speed and seamless foreign exchange. Google’s approach, however, is distinct in its emphasis on institutional programmability and bank money on-chain [7]. The company claims that GCUL can support billions of users and hundreds of institutions, leveraging the scale of its cloud infrastructure [8].

The development of GCUL is part of an emerging trend in which major technology firms are competing to define the next generation of financial settlement infrastructure. This move has drawn attention to the potential implications for Ethereum, which currently dominates the stablecoin and tokenized asset settlement markets. Ethereum held over 52% of the stablecoin settlement market in August 2025, with Google’s GCUL positioned as a potential competitor [9]. However, experts like Chuk Okpalugo from Paxos have downplayed its immediate impact, noting that GCUL is a permissioned chain and anti-stablecoin by design [10].

Despite the concerns about Ethereum’s market share, the broader implications of GCUL are still uncertain. While GCUL may not directly replace Ethereum in the open network space, its institutional-first approach could attract a significant portion of tokenized collateral, settlement, and FX activity. The success of GCUL will depend largely on its ability to attract a broad range of financial institutions and its interoperability with existing blockchain ecosystems [11].
