In recent years, the term Blockchain as a Service has evolved from a technical curiosity to a strategic model adopted by companies across various sectors, from fintechs to supply chains. It promises to deliver the benefits of blockchain technology — transparency, security, immutability — without companies needing to build all the infrastructure from scratch. Understand how companies like Azify can make a difference by offering secure, regulated, and multi-currency integrated Blockchain as a Service.
What is Blockchain as a Service?
Blockchain as a Service is a cloud-based service model that allows companies to use blockchain platforms provided by third parties — specialized providers — for creating, hosting, and operating applications based on blockchain, without needing to manage all the hardware infrastructure, node maintenance, network security, and other operational components.
Main features:
Ready infrastructure: servers, nodes, public or private/hybrid blockchain networks already set up for use.
Plug-in software APIs and modules: connectors, SDKs, integrations that allow building (for example) smart contracts, digital identity, tokenization.
Less need to hire specialists or heavily invest in IT to set up nodes, maintain consensus, network security, etc.
More predictable operational costs, with subscription or pay-as-you-go models.

How does Blockchain as a Service work in practice?
To understand exactly how Blockchain as a Service works securely, let's break down its architecture and typical components.
Base blockchain infrastructure
It can involve blockchains private, public or hybrid. In the private or hybrid model, the nodes can be under the control of the client or the provider.
Cloud platforms are often used to host nodes, auxiliary databases, metadata storage, management interfaces.
Middleware components and APIs
APIs for interaction with smart contracts.
SDKs for developing specific applications (for example, to create tokens, record data, query distributed records).
Management interfaces: dashboards for monitoring nodes, checking status, performance metrics, security logs.
Plugable modules
Auth / management of digital identities (e.g., self-sovereign identity or integrations with KYC/AML).
Pre-configured smart contracts or templates that can be customized.
Tokenization of assets (real world assets – RWAs) or utilities / digital representations.
Distributed data registry (for example, for supply chain traceability, document history, etc.).
Operation and maintenance
The Blockchain as a Service provider typically takes care of node maintenance, software updates, network security, scalability.
The client focuses on building applications on this foundation, defining business rules, configuring specific modules, integrating them into their legacy systems or other services.
What are the differences between Blockchain as a Service and directly implementing blockchain on your own?
There are companies that choose to build their own blockchain infrastructure — setting up nodes, reaching consensus, maintaining security, auditing, scalability, etc. Comparing:
Aspect | Direct Implementation | Blockchain as a Service |
Initial Cost | High: purchase/rental of servers, hiring specialized personnel | Lower: infrastructure already provided by the provider |
Technical Complexity | High — setting up consensus, networks, security, redundancy, etc. | Lower — many parts are already ready |
Launch Speed | Slower: many infrastructure and validation steps | Faster: use of modules, APIs, and ready environments |
Scalability | May require complicated restructuring to grow | Providers scale infrastructure for the client or in the cloud |
Compliance / Security Responsibility | Client assumes much more direct risk | The provider can take care of many aspects, although the client still has responsibilities |
Custom Flexibility | Very high if the company has the team and resources | Good, but there may be limitations depending on the provider |
What are the main factors that explain the growth of Blockchain as a Service worldwide?
Several factors contribute to the accelerated adoption of Blockchain as a Service securely:
Security, trust, and traceability - Blockchain allows for immutable transaction records, which increases trust and facilitates audits. This is very important in regulated sectors (finance, healthcare, supply chain).
Cost reduction and speed - Instead of investing time and resources in base infrastructure, companies use ready-made platforms — gaining agility to test, launch, and scale.
Regulated innovation - As regulatory milestones are implemented (for example, laws regulating virtual assets, providing blockchain services, data protection), companies need solutions that are already prepared to meet regulatory standards.
Demand for interoperability and integration - With businesses crossing borders, there is a need to operate in different jurisdictions, currencies, and systems. Blockchain as a Service securely helps to standardize integrations, incorporate multi-currency, and ensure international compliance.
Diverse use cases - Smart contracts, digital identity, tokenization, distributed ledgers (for example, for supply chains, contracts, intellectual property) have applications in many sectors, driving broad adoption.
Institutional support and global digitization - Government, regulatory bodies, and large companies are increasingly open to the use of blockchain and virtual assets, creating incentives, regulations, and demand for secure solutions.
Technological evolution - Cloud providers, improvements in hardware, networks, cybersecurity, encryption, scalability solutions (sharding, layer 2, etc.) make practical use cheaper and more feasible.
Relevant market data:
The global market for Blockchain as a Service securely by 2025 has varied estimates according to The Business Research Company: some reports point to values between USD 6.9 billion and more, with projections that could reach USD 40-50 billion in the coming years.
CAGR (compound annual growth rate) estimates in the range of 40-60% for the period from the mid-2020s to 2030.
In terms of use segments, finance, supply chains, digital identity, and IoT are sectors leading the adoption.
Examples of products and services enabled by Blockchain as a Service
We list some practical use cases of applications enabled by Blockchain as a Service securely:
Smart Contracts: automated contracts that execute clauses when predefined conditions occur (for example, conditioned payments, release of resources, digital assets).
Digital Identity (Self-sovereign Identity): systems in which users control their credentials, with immutable logs, integrated checks (KYC/AML).
Distributed Records: maintain traceable supply chains, medical records, properties, document history — all stored in a distributed manner to prevent fraud or tampering.
Asset Tokenization: physical or financial assets represented digitally in tokens: real estate, artwork, commodities, bonds, etc. It facilitates liquidity, divisibility, trading.
International / Multi-currency Payments: secure Blockchain as a Service can enable operations in multiple currencies, with interoperability between blockchains or between blockchain and traditional financial systems, facilitating conversions, settlement, compliance for cross-border transactions.
International and national cases of Blockchain as a Service adoption
Blockchain as a Service is already present in different sectors and geographies:
