How the US-China Rivalry Is Splitting Global Blockchain Development

Blockchain technology is caught in the crossfire of the US-China rivalry. As the world’s two largest economies compete to lead in technology, both governments are racing to adopt blockchain but in very different ways.

While China seems to be investing massively in state-backed blockchain networks and its national digital currency, the United States focuses on regulation and private sector innovation.

Chinese leaders have pitched blockchain in recent years as a weapon for trade, data management and financial stability. Meanwhile, US policymakers and firms have advanced in stablecoins, crypto banking licenses and a digital dollar.

China’s Blockchain Push

Blockchain is part of China’s high-tech arsenal. Where the West saw decentralized crypto, Beijing subsequently saw blockchain as a state-owned “trust architecture,” one through which it could increase efficiency and control. According to Asia Times, Chinese policy has long viewed blockchain as a strategic layer of digital infrastructure; a trust architecture for trade, payments, records, logistics and public administration.

According to reports; President Xi Jinping has famously described blockchain as an important breakthrough and called for more rapid development and deployment. This approach led to early regulatory decisions (e.g. 2019 CAC blockchain regulations and their effect) as well as inclusion in national plans.

China’s government is pouring money heavily into permissioned or “alliance” blockchains, which are private networks operated by vetted institutions, not open public chains like Ethereum. This ensures that data remains under state control. A recent directive encourages building networks and privacy-preserving platforms for “trusted” circulation of data; even cross-border data spaces.

Blockchain is widely used for land records, invoicing and digital identity verification by Chinese provinces and cities.

Another area of blockchain activity in China on which the government also focuses is its digital yuan (e-CNY) project. The People’s Bank of China (PBOC) has run massive pilots of the e-CNY and, as of late 2025, had finalized more than 3.4 billion transactions for a total value of¥16.7 trillion ($2.4 trillion); approximately an 800% increase on its overall transaction volume from 2023.

Transaction volume on mBridge, a China-backed cross-border digital currency system that includes Hong Kong, Thailand, UAE and Saudi Arabia reached $55.0 billion in January of 2026. The use of e-CNY exceeded $2 trillion as of late 2025.

Based on reports, China even now intends to pay interest on e-CNY balances to encourage adoption. In short, this means China is internationalizing the yuan by means of blockchain technology, and creating parallel financial rails that reduce dollar dependence.

The growth of China’s blockchain-backed digital yuan (e-CNY) transaction volume reached $1 trillion by February 2025 and surpassed $2trillion by November 2025. 

Outside of finance, China’s security apparatus is using blockchain. The People’s Liberation Army is experimenting with blockchain for logistics and personnel records, while police agencies use it to secure digital evidence. Beijing has even established a Blockchain-based Service Network (BSN) that is designed to build a China-controlled global infrastructure for blockchain apps.

U.S. Blockchain Strategy and Regulation

Unlike China’s state-driven push, the U.S. approach to blockchain adoption is more market-driven. The response from the US government is not a uniform blockchain strategy for all, but rather various guiding principles being formulated by different agencies and Congress as to how they plan on handling digital assets. The aim is to design a regulation framework for the cryptocurrencies and use private-sector innovation.

One of the most noteworthy US developments has been legislation regarding stablecoins. In mid-2025, the US Senate passed GENIUS Act with bipartisan support,  the first federal stablecoin law. The law requires dollar-backed coins such as USDC to maintain liquid reserves and meet audit requirements.

This legislation was praised by legal experts as a welcome development, because now there’s clarity in an industry that is worth hundreds of billions. Under this new rule, issuers like Circle (USDC) are growing. At the beginning of 2025; USDC’s supply surpassed $60billion with lifetime transactions exceeding $1trillion.

The U.S. is using stablecoins to expand dollar dominance in digital payments In fact, in late 2025, multiple crypto companies like Circle, Ripple and Paxos; received conditional national trust bank charters enabling them to provide banking services on digital assets.

Unlike China, the US has a complete ban on government controlled digital currencies. Instead, US central bankers have been studying a digital dollar (central bank digital currency) but made no promise yet to roll one out. However; the US encourages innovation in cryptocurrency like state-of-the-art projects such as CBDCs and public blockchains like the Digital Dollar Project’s Ethereum pilots are being considered.

At the same time; federal agencies like the SEC and CFTC are figuring out how to classify cryptocurrencies (security vs commodity). In early 2026; bills in the House and Senate seek to clarify what constitutes crypto assets clearly; though the debate goes on.

Overall; regulators are tightening oversight in US blockchain policy; while simultaneously legalizing stablecoins and crypto-banks. 

Geopolitical Impact on Adoption

The US-China rivalry is creating a split in global blockchain adoption and this has several effects:

Technological fragmentation: Given China is pushing its own standards (China Standards 2035) and building infrastructure like the BSN; while US/Allies push for open networks; blockchain tech could divide globally. Authorities warn of digital fragmentation along geopolitical lines; in which different blocs use incompatible systems. 

Trade and finance: Competing blockchain rails allow some countries to transact beyond dollar controls. According to the Atlantic Council, the heat that mBridge brings is a sign of alternative payment system gaining ground.

Emerging economies may adopt China-aligned networks (a continuation of BRICS de-dollarization discussions) while many others continue with USD-backed stablecoins. The IMF and experts say this mix of digital currencies could increase prices and complication in cross-border commerce.

Regulatory competition: The new stablecoin law (2025) in Hong Kong was explicitly designed to bring the financial center into line with Beijing’s e-CNY plan. This has prompted a surge in US crypto diplomacy; like pushing requests for dollar stablecoins from allied countries. Such competition could leave developing countries in the middle.

Economic security: The competition might also cause blockchain adoption in areas closely related to national security. The supply chains for things like semiconductors, rare earth mining, or logistics may adopt blockchain solutions that allow them to trust without dependence on rival tech.

China’s 2026 economic plan even cites blockchain as one of the drivers behind the core digital economy growth. The US, who does not want to lose its leading tech producers position to China, has already begun considering blockchain while developing strong supply chains.

To make the long story short, Washington and Beijing are pulling the blockchain adoption curve in two directions. China is constructing a “digital trust layer,” with state control, whereas the US ecosystem develops under market forces and new laws.

Despite the tension, both countries are expected to continue to see rapid, advancements in their, respective, blockchain, industries.

Expert Analysis

The US-China rivalry, analysts warn, will have long-lasting effects. China has filed roughly three times the number of blockchain patents than the US; and is speeding up applications for first-mover advantage.

In this new age, the battle over blockchain and digital currencies is every bit as geopolitical as it is technological. The contest represents the reordering of global monetary governance. Blockchain adoption will align more and more closely with political blocs. Some countries might plug into Xi’s “permissioned” networks, while others rely on Western-led public blockchains and stablecoin rails.

At the same time, blockchain proponents argue, the technology’s fundamental advantages which are trustless transactions, transparency, efficiency; are still universal. 

So, the rivalry effect could go in any direction: it could drives investment and also divide resources. For the average user and developer, that can mean more options but also added complexity. “We run the risk of competing in an information environment designed by competitors,” a research analyst says.

Conclusion

The US-China rivalry is speeding up diversity in blockchain adoption but also driving it in different directions. China’s state-driven aggressiveness (via digital yuan, alliance chains and BSN) has driven rapid adoption of blockchain for finance and government. The US has also led adoption by allowing dollar stablecoins and crypto banks infrastructure.

The result is a broken, multipolar blockchain ecosystem: Some networks and currencies are aligned with Beijing’s strategy; others with Washington’s.

In the end, ordinary users might gain additional blockchain-enabled services, but will have to find their way in two separate ecosystems.

Glossary

Blockchain: a digitized system for recording transactions, with blocks linked together. It is decentralized (no central authority) and data cannot be tampered with once recorded. 

Central Bank Digital Currency (CBDC): A digital version of a country’s fiat currency; administered and regulated by the domestic central bank. 

Stablecoin: A cryptocurrency with a stability by pegging it to reserve asset (e.g. US dollar). Examples include USDC or USDT. They are used as cryptocurrencies for fast digital payments; and for trading between blockchains.

mBridge: mBridge is a China-led cross-border central bank payments platform using blockchain. It links the digital currencies of several countries in order to settle trade without involving the dollar.

Stablecoin Law (GENIUS Act): US federal law enacted in 2025 and establishing rules for dollar-backed stablecoins.

Frequently Asked Questions About US-China Rivalry

What is the US-China rivalry?

It describes the US and China competing for leadership in blockchain. While the US is all about regulation and cheering on private enterprise; China builds its own networks (digital yuan, state-run blockchains). The competition is global and touches on issues of blockchain adoption and standards.

How does China’s adoption of the blockchain differ from the US?

China is heavily focused on permissioned “alliance chains” and has integrated its CBDC (digital yuan) into commerce. The US in contrast; has allowed public blockchains (Bitcoin, Ethereum) and is now writing rules for stablecoins and crypto banks.

What is the digital yuan (e-CNY)?

The e-CNY is China’s central bank digital currency, built on blockchain technology. It has been tried in many cities and cross-border projects. In 2025; e-CNY managed trillions of dollars in transactions. China wants to promote its use to enhance payment transparency and cut dependence on the US dollar.

What is a stablecoin, and how do the US and China view it?

Stablecoins are cryptocurrencies that are pegged to a fiat currency (usually the dollar). The United States also recently introduced a stablecoin law (the GENIUS Act) to regulate dollar-backed stablecoins. China however; has effectively banned private stablecoins and crypto; opting to introduce its own CBDC (the e-CNY) with a tight reign.

Is this rivalry going to split the blockchain ecosystem in two?

Most analysts predict that a partial split is more likely. China’s networks and US networks may not easily communicate with each other. That could result in a “split”, with separate standards and blockchains for each nation. Still, open-source protocols may act as bridges.
