Reserve Bank of Australia Taps Hedera’s Enterprise Blockchain for Central Bank Digital Currency Research

The Reserve Bank of Australia has incorporated Hedera’s enterprise blockchain solution into Project Acacia, its flagship initiative exploring wholesale central bank digital currencies. The central bank selected HashSphere, Hedera’s private blockchain infrastructure, alongside three other distributed ledger platforms for the pilot program examining digital money applications in institutional markets.

Institutional Blockchain Infrastructure Takes Center Stage

Project Acacia represents one of Australia’s most comprehensive explorations of digital currency infrastructure for institutional use. The initiative, launched in collaboration with the Digital Finance Cooperative Research Centre, selected Hedera’s HashSphere alongside Redbelly Network, R3 Corda, and Canvas Connect for testing wholesale CBDC functionality.

Australian Payments Plus, the national payment scheme operator and Hedera Council member, deployed the private HashSphere network specifically to meet regulatory requirements. The organization operates Australia’s core domestic payment systems and serves as the technical bridge between Hedera’s infrastructure and the central bank’s research objectives.

HashSphere addresses a fundamental challenge in enterprise blockchain adoption: providing the efficiency benefits of distributed ledger technology while maintaining the privacy and compliance standards required by regulated financial institutions. The platform operates as a standalone private network powered by Hedera’s proven technology stack.

Testing Real Money Transactions Across Multiple Asset Classes

Project Acacia encompasses 24 distinct use cases spanning multiple sectors of Australia’s financial system. The program includes 19 pilot implementations involving actual money and asset transactions, plus five proof-of-concept scenarios using simulated transactions. Participating organizations range from major banks including Commonwealth Bank, Westpac, and ANZ to technology providers like Fireblocks and Northern Trust.

The testing framework covers diverse asset classes including fixed income securities, private market instruments, trade receivables, and carbon credits. Settlement mechanisms under evaluation include stablecoins, bank deposit tokens, and the pilot wholesale CBDC itself. This comprehensive approach allows researchers to examine how different digital money forms might function within Australia’s existing financial infrastructure.

Research conducted by the Digital Finance Cooperative Research Centre estimates that modernizing Australia’s digital finance capabilities could generate AU$24 billion in annual productivity improvements for the economy.

Enterprise Blockchain Architecture for Regulated Markets

HashSphere launched in March 2025 to solve the tension between blockchain efficiency and regulatory compliance. Traditional public blockchains offer technological benefits but present compliance challenges for regulated institutions. Fully private networks address privacy concerns but often create vendor dependency issues.

The HashSphere architecture provides enterprise-grade data privacy through standalone private networks while maintaining planned interoperability with Hedera’s public infrastructure and other private networks. The platform supports EVM-compatible smart contract deployment and provides access to Hedera’s Token Service, Consensus Service, and Stablecoin Studio.

Rob Allen, who leads Future Payments strategy at Australian Payments Plus, explained the organization’s technical approach: “We are interested in HashSphere primarily for its enhanced privacy and regulatory compliance, while also needing network interoperability for the seamless and transparent interchange of stablecoins between public Hedera and private HashSphere.”

Central Bank Digital Currency Development Timeline

Project Acacia follows a structured research timeline that began with consultation in November 2024. The program selected its 24 use cases in July 2025, when the Australian Securities and Investments Commission granted regulatory relief for pilot testing. By December 2025, all proof-of-concept use cases had been completed and wholesale CBDC deployment was underway across multiple platforms.

The final research report is expected in early Q2 2026. Brad Jones, Assistant Governor for Financial Systems at the Reserve Bank of Australia, emphasized the strategic importance of the work: “Ensuring that Australia’s payments and monetary arrangements are fit-for-purpose in the digital age is a strategic priority for the RBA and the Payments System Board.”

The research initiative operates under oversight from multiple regulatory bodies including the Australian Securities and Investments Commission, the Australian Prudential Regulation Authority, and the Treasury Department.

Global Institutional Blockchain Adoption Pattern

Hedera’s selection for Project Acacia continues a pattern of institutional adoption across multiple jurisdictions. In the United Kingdom, Lloyds Banking Group and abrdn executed tokenized collateral transactions on Hedera infrastructure, representing a first for that market. The state of Wyoming selected Hedera as a blockchain candidate for its Frontier Stable Token initiative.

The Bank of England and BIS Innovation Hub chose Hedera as one of two Layer 1 networks for their DLT Challenge, highlighting the platform’s credibility among central banking institutions worldwide.

The Reserve Bank of Australia has not committed to issuing a wholesale CBDC or mandating specific infrastructure for future digital currency operations. Project Acacia remains explicitly a research initiative designed to inform policy decisions rather than implement production systems.

Private Network Deployment for Compliance Requirements

The deployment of HashSphere for Project Acacia specifically addresses regulatory requirements that wholesale CBDC testing not occur on public blockchain infrastructure. Australian Payments Plus configured the private network to satisfy these privacy mandates while maintaining technical connections to public stablecoin settlement rails.

This hybrid approach allows researchers to examine how private institutional networks might interact with public blockchain infrastructure in practice. The testing framework evaluates whether regulated institutions can maintain compliance standards while accessing the efficiency benefits of distributed ledger technology.

Beta partners for HashSphere include Australian Payments Plus, Blade Labs, and Vayana ahead of the platform’s broader commercial launch. The enterprise blockchain solution provides fully managed nodes with service-level agreement guarantees, addressing operational concerns that have historically limited institutional blockchain adoption.

While Project Acacia represents research rather than production deployment, infrastructure choices made during experimentation often influence future policy and technology decisions. The Reserve Bank of Australia’s selection of multiple blockchain platforms for testing suggests an approach that prioritizes technological diversity over early standardization on specific solutions.
