Privacy: The Missing Ingredient for Blockchain’s Widespread Business Adoption
The blockchain industry has been buzzing with promise for years. While it’s made impressive inroads in finance and healthcare, a critical barrier still stands in the way of broader business adoption: privacy.
According to Paul Brody, EU’s global blockchain leader at EY, privacy is the crucial element that could catalyse widespread blockchain use across various sectors. Ahead of the Token2049 conference in Singapore, Brody shared valuable insights on how addressing privacy concerns could unlock blockchain’s full potential for businesses.
Why Privacy Matters for Blockchain Adoption
Blockchain technology offers numerous benefits, including transparency, decentralisation, and security. However, these very attributes can become hurdles when it comes to privacy. For businesses, especially large enterprises, the need for privacy on blockchain networks is paramount.
Privacy Challenges in Blockchain
- Lack of Native Privacy: Traditional blockchains do not natively offer privacy. Transactions are recorded transparently, which can expose sensitive business data.
- Data Sensitivity: Enterprises often handle confidential information, such as contract details and competitive pricing strategies. They need to keep this data private while still leveraging blockchain’s benefits.
- Public Chain Privacy Issues: Achieving privacy on a public blockchain is notoriously difficult, which limits its utility for many business applications.
How EY Is Tackling Privacy with Blockchain
EY is addressing these privacy concerns with innovative solutions. One of their key projects is Nightfall, a zero-knowledge proof (ZKP) technology built on Ethereum Layer 2 and Polygon. Here’s how it’s making a difference:
- Secure Transactions: Nightfall allows for secure transactions without exposing sensitive data.
- Private Smart Contracts: EY’s Off-Chain Contract Manager for renewable energy showcases how Nightfall can be used to create fully private on-chain smart contracts.

Supply Chain Management: A Prime Example
Supply chain management is often cited as a prime use case for blockchain technology. However, privacy concerns have slowed its adoption. Here’s why:
- Need for Privacy: Effective supply chain tracking requires detailed data that companies may not want to expose publicly.
- Current Limitations: Despite blockchain’s theoretical benefits for trust and traceability, real-world applications are lagging due to insufficient privacy measures.
EY’s Progress in Supply Chain Blockchain
- Pilot Project: EY is running its first pilot for end-to-end supply chain traceability on public Ethereum with full tokenisation.
- Ongoing Challenges: Brody notes that while progress is being made, achieving effective privacy in supply chain applications remains a significant challenge.
Why This Matters for Businesses
For businesses, especially those handling sensitive information or operating in competitive markets, integrating privacy into blockchain applications is crucial. Here’s why:
- Enhanced Security: Privacy ensures that confidential data remains secure and inaccessible to unauthorised parties.
- Competitive Advantage: Businesses can leverage blockchain’s benefits without risking the exposure of sensitive information.
- Broader Adoption: As privacy solutions become more robust, businesses will be more inclined to adopt blockchain technology for various applications.
Conclusion
The blockchain industry stands on the brink of a major breakthrough, but privacy remains a significant hurdle. EY’s innovations, such as Nightfall and the Off-Chain Contract Manager, are steps in the right direction. Addressing privacy concerns will be key to unlocking blockchain’s full potential for business adoption, particularly in sectors like supply chain management.
As we move forward, it’s clear that privacy isn’t just an add-on but a foundational requirement for the successful integration of blockchain technology in business. Embracing these advancements will help bridge the gap and pave the way for more widespread adoption of blockchain in the corporate world.
