Nextblock backs Soda Labs with $3 million to bring programmable privacy to banks on public blockchains

Luxembourg-based venture firm Nextblock has committed $3 million to the Soda Labs seed round, backing a bet that institutions will only move onto public blockchains if they can keep their data private.

Soda Labs is building Soda Bubble, a chain-agnostic privacy coprocessor that lets banks, payment providers and tokenization platforms run confidential computations on existing chains, with controlled disclosure when required.

Programmable privacy could unlock institutional blockchain adoption

Public blockchains offer transparency, verifiability and access to global liquidity. However, these same characteristics can create difficulties for businesses that cannot disclose their entire financial activity to competitors, customers or the wider public.

A company moving funds between treasury accounts may not want its balances and transaction patterns publicly visible. Similarly, an asset manager may need to protect investment positions while still meeting applicable reporting and compliance obligations.

Soda Labs aims to address these concerns through programmable privacy, an approach that allows developers to define which computations remain confidential and how information can be disclosed under specified conditions.

The Soda Labs seed round will help the startup expand Soda Bubble, its chain-agnostic privacy coprocessor. The technology is designed to process privacy-sensitive workloads associated with different blockchain networks without publicly exposing the underlying data.

Avishay Yanai, co-founder and chief executive officer of Soda Labs, described the company’s objective in the announcement.

He added that Soda Bubble is designed to provide banks, payment companies and tokenization platforms with privacy and controlled disclosure on existing chains.

The Soda Labs seed round will support the company’s efforts to move beyond initial testing and toward wider commercial deployment.

AI and quantum computing add to blockchain security concerns

Privacy is not the only infrastructure challenge attracting attention from blockchain investors. The development of artificial intelligence and advances in quantum computing are also raising questions about the long-term security of cryptographic systems.

According to van Poecke, AI is changing the speed at which security researchers and potential attackers can identify software vulnerabilities. This creates additional pressure on blockchain developers to strengthen auditing procedures, testing processes and ongoing security assessments.

Van Poecke says AI is already changing the economics of security research. It can help researchers and attackers find implementation vulnerabilities much faster, which means protocols need to become substantially more rigorous about auditing and continuous testing.

Quantum computing presents a different category of risk. A sufficiently powerful quantum computer could undermine certain cryptographic methods that protect digital communications and blockchain transactions.

Although the timing of such a breakthrough remains uncertain, preparing for future cryptographic threats could become increasingly important for infrastructure providers serving institutional customers.

Long-term resilience, privacy controls and the ability to adapt to new computing threats could influence which infrastructure companies secure enterprise partnerships.

The Soda Labs seed round places the startup within this broader market for cryptographic tools intended to support more secure blockchain applications.

What the Soda Labs seed round means for crypto investors

The investment offers an indication of where some venture capital firms see opportunities in the next phase of blockchain adoption.

While cryptocurrency markets often focus on token prices, trading volumes and speculative demand, institutional participation also depends on the availability of reliable underlying technology.

Soda Labs plans to use the funding to expand its team and validator network, develop commercial integrations and advance pilot projects involving banks, payment providers and tokenization platforms.

Potential opportunities lie in the adoption of blockchain infrastructure, particularly technology that enables regulated institutions to use public networks while protecting sensitive information.

However, the investment should not be interpreted as a guarantee of commercial success. The company’s ability to attract additional customers, demonstrate reliable performance and convert pilot projects into recurring revenue will remain important measures of progress.

The Soda Labs seed round also does not, by itself, establish that any associated cryptocurrency will appreciate in value. The funding is directed toward the company’s infrastructure and commercial development, rather than representing a disclosed purchase of a particular digital asset.

Investors assessing the sector should monitor future product releases, institutional partnerships, validator expansion and evidence of sustained customer demand.

If programmable privacy can meet institutional requirements for confidentiality, controlled disclosure and security, it could help broaden the range of financial activities conducted on public networks.

The extent of that opportunity will depend on execution, adoption and the company’s ability to compete in an evolving cryptographic infrastructure market.
