Blockchain as a Service (Blockchain SaaS) - How Does It Work?

Blockchain technology has been gaining popularity in recent years for its ability to revolutionize the way transactions are made and records are kept. According to a report by MarketsandMarkets, the global BaaS market size is expected to grow to USD 15,455.0 million by 2023, at a CAGR of 90.1% during the forecast period. With its decentralized nature and high level of security, blockchain has the potential to transform various industries, from finance to supply chain management. However, despite its promising features, implementing blockchain technology can be costly and time-consuming. This is where Blockchain as a Service (BaaS) comes in, providing a more accessible and cost-effective way for businesses to adopt and leverage blockchain technology.

1. What is a Blockchain SaaS (Blockchain as a Service)?

Blockchain as a Service (BaaS) is a cloud-based service that allows businesses to create, host, and manage their own blockchain networks without the need for significant investment in hardware, software, or technical expertise. BaaS providers offer a range of blockchain-related services, such as infrastructure, platform, and software, enabling businesses to quickly and easily deploy blockchain technology in their operations.
The BaaS market is relatively new, but it is growing rapidly. According to a report by MarketsandMarkets, the global BaaS market is expected to reach $30.4 billion by 2024, with a Compound Annual Growth Rate (CAGR) of 90.1% from 2019 to 2024. This growth can be attributed to the increasing demand for blockchain technology across various industries, as well as the need for more efficient and cost-effective ways of implementing it.

2. What are the Benefits of Blockchain as a Service?

A. Cost Savings:

BaaS eliminates the need for businesses to invest in expensive hardware, software, and technical expertise required to build and manage their own blockchain networks. By using BaaS, businesses can save on upfront costs and ongoing maintenance costs, which can be a significant barrier to entry for many organizations.

B. Increased Efficiency:

BaaS providers offer a range of blockchain-related services, such as infrastructure, platform, and software, enabling businesses to quickly and easily deploy blockchain technology in their operations. This allows organizations to focus on their core business functions, rather than spending time and resources on managing their blockchain networks.

C. Improved Security:

Blockchain technology is known for its high level of security, as each transaction is verified and recorded by multiple nodes in the network, making it virtually impossible to tamper with the data. By using BaaS, businesses can benefit from the security features of blockchain without having to invest in the technical expertise required to build and manage their own blockchain networks.

D. Scalability:

BaaS providers offer flexible and scalable solutions, allowing businesses to quickly and easily adjust their blockchain networks to meet changing business needs. This ensures that businesses can scale their operations without having to invest in additional hardware or technical expertise.

3. What are the Disadvantages of Blockchain as a Service?

A. Reliance on Service Provider:

Businesses that use BaaS are dependent on their service provider to maintain and update their blockchain networks. This can be a disadvantage if the service provider experiences downtime, security breaches, or other issues that affect the availability and reliability of the blockchain network.

B. Limited Control:

BaaS providers may limit the level of control that businesses have over their blockchain networks. This can be a disadvantage for businesses that require a high level of customization and control over their blockchain networks.

C. Integration Challenges:

Integrating blockchain technology with existing systems and processes can be a challenge, particularly for businesses that use legacy systems. This can result in additional costs and delays in implementing blockchain technology.

D. Limited Scope:

BaaS solutions may be limited in terms of their scope and functionality, particularly for businesses that require specialized blockchain solutions.

4. How Does a Blockchain as a Service Work?

BaaS providers offer a range of blockchain-related services, such as infrastructure, platform, and software. These services can be used by businesses to quickly and easily deploy blockchain technology in their operations. The specific steps involved in using BaaS may vary depending on the service provider, but the following are the general steps involved in using BaaS:

Step 1: Choose a BaaS Provider:

Businesses need to choose a BaaS provider that best fits their needs. Factors to consider when choosing a BaaS provider include the cost, features, and scalability of the solution.

Step 2: Create a Blockchain Network:

Once a BaaS provider is chosen, businesses can create their own blockchain network by selecting the type of blockchain, setting up the nodes, and defining the rules for the network.

Step 3: Deploy Smart Contracts:

Businesses can use BaaS to deploy smart contracts, which are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. Smart contracts can be used to automate various business processes, such as supply chain management and payment processing.

Step 4: Integrate with Existing Systems:

Businesses can integrate their blockchain network with existing systems and processes to ensure seamless operations. This may require additional customization and development work, depending on the complexity of the integration.

Step 5: Manage and Monitor the Network:

Once the blockchain network is up and running, businesses can use BaaS to manage and monitor the network, including adding or removing nodes, updating rules, and ensuring the security and availability of the network.

5. How Much is Blockchain as a Service?

The cost of blockchain as a service (BaaS) varies depending on the service provider and the specific features and services required by the business. Some BaaS providers charge a subscription fee based on usage, while others charge a one-time fee for set-up and customization.
For example, Microsoft Azure's BaaS solution, Azure Blockchain Service, offers different pricing tiers based on the number of nodes and the level of data throughput required by the business. The pricing starts at $0.35 per hour for a single-node basic configuration and goes up to $4.88 per hour for a multi-node premium configuration.

IBM Blockchain Platform, another popular BaaS solution, offers flexible pricing options based on the number of users, transactions, and data storage requirements. The pricing starts at $0.50 per hour for a single-member network and goes up to $2.50 per hour for a multi-member network.
Amazon Managed Blockchain, a BaaS solution by Amazon Web Services, offers a simple pay-as-you-go pricing model, with no upfront costs or long-term commitments. The pricing starts at $0.01 per hour for a single-node network and goes up to $0.10 per hour for a multi-node network.
The cost of BaaS also depends on the level of customization and integration required by the business. Some BaaS providers offer additional services, such as consulting, development, and support, which can add to the overall cost. Businesses should carefully evaluate their needs and budget before choosing a BaaS provider and selecting a pricing plan that fits their requirements.

Final considerations

Blockchain as a Service (BaaS) is a cloud-based service that allows businesses to quickly and easily deploy blockchain technology in their operations, without the need for significant investment in hardware, software, or technical expertise. BaaS offers several benefits, including cost savings, increased efficiency, improved security, and scalability. However, it also has some disadvantages, such as dependence on the service provider, limited control, integration challenges, and limited customization options. Despite these challenges, the BaaS market is expected to grow rapidly in the coming years, as more businesses adopt blockchain technology to streamline their operations and enhance their competitiveness.
