Security is becoming an increasingly important issue, especially with the rise of quantum computing. While traditional encryption methods used in blockchain have been effective, they are now facing new challenges. This has sparked the development of next-generation blockchains that are designed to resist quantum threats. One example is Arqit, which is taking a unique approach by combining quantum key distribution and post-quantum cryptography to secure data in ways that were once considered impossible.
As the demand for safer blockchain platforms grows, many are looking to create systems like Arqit, where their blockchain assets are protected against the potential risks posed by quantum computing.
This blog will explore how to develop a secure blockchain platform like Arqit Quantum Blockchain, covering the key technologies and strategies for building a future-proof platform. Whether you’re an entrepreneur, developer, or researcher, this guide will help you dive into the world of quantum-secure blockchains.
Overview of the Arqit Quantum Blockchain Platform
Arqit has developed an innovative quantum blockchain platform that uses quantum-safe encryption to protect communications and transactions across devices and networks. At its core, the platform utilizes Symmetric Key Agreement technology, which generates unbreakable encryption keys, even by quantum computers.
Key Features of the Quantum Resistant Platform Like Arqit
- Quantum-Safe Encryption: Arqit’s SKA technology creates encryption keys that are safe from future quantum computing threats, ensuring long-lasting data protection.
- Platform-as-a-Service: Arqit offers its quantum-safe encryption as a cloud-based service, so users can easily integrate it into existing systems without major changes or disruptions.
- Lightweight Software Agent: The platform includes a small software agent that can be quickly deployed on devices, allowing them to generate encryption keys with other devices securely. It’s efficient enough to work on even the smallest devices.
- Dynamic Key Generation: Arqit’s system can generate a large number of encryption keys that are tailored to specific needs, such as different group sizes or refresh rates. This flexibility is essential for modern applications that require secure communication across many devices.
How does the Symmetric Key Agreement Work?
Arqit’s SKA process for establishing a secure communication channel involves a few simple steps:
- Authentication: Devices authenticate themselves with the SKA platform.
- Key Generation: The platform creates public-private key pairs for different encryption mechanisms and shares the public keys with the devices.
- Secret Encapsulation: Each device creates a random secret and protects it using the public keys from the platform.
- Key Combination: The devices send their secrets back to the platform, which combines them to form a shared symmetric key using a hash function.
This approach ensures that the generated encryption keys are secure, scalable, and efficient, making them ideal for a wide range of devices and applications.
Key Market Takeaways for Blockchain

Much of this growth is driven by the increasing demand for secure, transparent transactions across industries like finance, healthcare, and supply chain management. For example, the U.S. blockchain market alone could be worth USD 137.67 billion by 2032, showing a clear shift toward widespread adoption.
But with growth comes new challenges. As blockchain adoption rises, so does the need for stronger cybersecurity. One of the biggest concerns is the rise of quantum computing, which threatens to break current encryption methods like RSA and ECC, which have long been the backbone of digital security. As quantum computers get more powerful, traditional encryption could be more vulnerable to attacks, putting sensitive data at risk.
To address this, many blockchain projects are adopting quantum-resistant technologies. For example, the Quantum Resistant Ledger uses the eXtended Merkle Signature Scheme, designed to resist quantum attacks. Likewise, Nervos Network has built a flexible Layer 1 architecture that can easily integrate quantum-resistant security as it evolves.

What is the Business Model Of Arqit?
Arqit has developed a unique business model built around its Symmetric Key Agreement Platform-as-a-Service, offering quantum-safe encryption solutions to protect communications across devices and networks. The platform helps generate encryption keys that are secure against both current and future cyber threats, including the risks posed by quantum computing.
Arqit offers the SKA Platform in two versions: a cloud-based Platform-as-a-Service and a sovereign private instance, allowing businesses to choose the level of security that fits their needs in today’s hyper-connected world.
Business Model Overview
- Product Offering: The SKA Platform enables devices to collaboratively generate encryption keys, improving security without relying on traditional public key infrastructures. This approach fits perfectly with the Zero Trust security model, which reduces dependency on trusted third parties and ensures a more secure communication environment.
- Revenue Generation: Arqit’s primary revenue comes from partnerships with original equipment manufacturers and system integrators around the world, including in the US, Europe, and Asia-Pacific.
In fiscal year 2023, the company made a strategic shift from direct sales to channel partnerships, beginning to see revenue from these collaborations, which is expected to grow as the business expands.
Financial Performance
Arqit’s financial journey has seen some ups and downs. In the fiscal year ending September 30, 2023, the company reported revenue of $640,000, a decrease compared to the prior year. This drop was due to a shift from selling high upfront perpetual licenses to offering more predictable operational licenses with recurring revenue. For fiscal year 2024, revenue dipped further to $293,000, but the company views this as part of a longer-term strategy that could lead to growth in recurring revenue as more customers adopt its services.
Despite the lower revenue, Arqit has worked hard to keep costs under control. By September 2023, monthly operating expenses had been reduced to around $3.2 million, with cash reserves of about $44.5 million thanks to funding rounds. This financial discipline has been key as Arqit transitions its business model.
Funding Strategy
Arqit has been actively raising funds to support its growth. In December 2022, the company launched an at-the-market equity offering program, which allows it to issue up to $50 million in shares. By September 2023, they had raised around $11.5 million through this initiative, selling nearly 7.8 million shares.
These efforts are helping Arqit maintain liquidity as it transitions to a new business model and expands its service offerings, positioning itself for long-term success in the rapidly evolving cybersecurity market.
Why There is a Need for Quantum Resistant Platforms For Blockchain?
As quantum computing progresses, it poses a real threat to blockchain’s security. Current encryption methods like RSA and ECC, used to protect transactions, could be easily broken by powerful quantum computers. Google’s 2019 breakthrough showed that quantum computers could perform certain tasks, like factoring large numbers, way faster than today’s supercomputers.
Experts say that within 10 to 15 years, quantum tech could easily crack the encryption that keeps blockchain secure.
To stay ahead of this risk, companies are already building blockchain platforms that are “quantum-resistant.” These use new cryptographic algorithms, like lattice-based and hash-based encryption, which are designed to be safe from quantum attacks.
For instance, the QRL uses a special signature system called XMSS to make its network more secure. IBM is also working on “quantum-safe” technologies to protect its blockchain solutions in the quantum era.
With the rapid growth of quantum computing, there’s a pressing need to prepare for its impact. According to the World Economic Forum, quantum computing could start breaking encryption as soon as 2030, putting billions of dollars in blockchain transactions at risk. By adopting quantum-resistant technologies today, businesses can future-proof their blockchain systems and keep their networks secure and trustworthy for years to come.
