Understand transactional IoT: The future of Internet of Things

With the growth in the Internet of Things (IoT), more and more industries are being influenced by smart connectivity. One of the newer achievements leading to this influence is transactional IoT, also referred to as tIoT. This article provides deep insight into this concept, its applications, benefits and possible futures, by exploring its characteristics.

What is transactional IoT?

Transactional IoT involves blending IoT and blockchain technologies together for near real-time transactions between connected devices that are decentralised and trackable. With transactional IoT, connected devices can trade with each other on their own, without having to bother with intermediaries, and the proof of every single transaction is recorded in a decentralised ledger. As a result, such a process cannot be faked, disputed or altered – all parties involved see the same information and it cannot be changed.

Key components of transactional IoT

• IoT devices: Sensors, actuators and other smart devices that collect and transmit data.
• A decentralised ledger of transactions: Blockchain, a record-keeping system for digital transactions, runs on multiple hard drives called nodes. When added to the ledger, each activity is given an immutable code that cannot be altered. This creates a perfect record of transactions, eliminating the need for a central administrator or authority as individual nodes copy the record.
• Smart contracts: Self-enforcing contracts based on computer code that represents the terms, meaning that the code will automatically respond to agreements and regulations between the parties.

Key differences between traditional IoT and transactional-IoT

Feature	Traditional IoT	Transactional-IoT
Data security	Centralised	Decentralised
Transparency	Limited	High
Cost	Higher operational cost	Lower costs due to automation
Transaction speed	Dependant on intermediaries	Real-time
Scalability	Limited	Improved with blockchain

 Applications of transactional IoT

Transactional IoT has a wide range of applications across various industries:

• Supply chain management: tIoT ensures transparency and traceability of goods from production to delivery.
• Healthcare: Secure and accurate tracking of medical supplies and patient data.
• Energy management: Autonomous transactions between smart grids and devices for efficient energy distribution.
• Smart cities: Managing public utilities, transportation and other urban services through automated transactions.

Benefits of transactional IoT

Transactional IoT can overhaul industries and transform the way we live and operate. Let’s examine the four primary benefits of transactional IoT:

1. Enhanced security

Security of blockchain tIoT exploits the built-in security properties of the blockchain altogether, including its inherent decentralisation and cryptographic hashing, to prevent any third-party attackers, governments or organisations from gaining access or tampering with the data transmitted over the network. In each transaction, the details relevant to that transaction are compiled into a block and added to the sequence of blocks already comprising the blockchain, with the new block containing a link to the one previously added.

Device authentication: tIoT devices can authenticate themselves without human intervention using blockchain-based credentials, reducing the risk of security breaches caused by malicious actors or devices that could undermine integrity in sectors such as healthcare or finance.

2. Improved transparency

Decentralised ledger: All transactions are written into and open to every participant’s ledger. This is one way blockchain ensures transparency – there is no need for a central authority and there is little room for fraud.

Auditability: In a tIoT network, all transactions are traceable, and therefore audit trails are available for most challenges. In supply chain management, for example, auditing the origins of products and their journeys towards the consumer are vital for quality management and regulatory compliance.

3. Reduced costs

Removal of middlemen: tIoT is an intermediary for commerce and communication processes. Smart contracts can potentially upend middlemen who facilitate agreement-making between parties. For example, a smart contract can perform the same functions for an agreement as a company does for commercial interactions.

Operational efficiency: tIoT automated transactions and data exchange eliminate or substantially reduce human intervention in operations. It allows savings in operation through computerisation, which could benefit different sectors of economy such as manufacturing and logistics.

4. Increased efficiency

Real-time processing: tIoT supports processing transactions and data in real-time, which is essential for those applications that must take immediate action, such as power management in smart grids, or inventory tracking in retail.

Efficient workflows: Automated transactions and smart contracts help streamline workflows, providing more timely delivery, better insights and greater productivity. For example, in the automotive sector, tIoT can reduce costs and deliver the right spare parts from the right supplier at the moment it’s needed.

5. Enhanced data integrity

Unchangeable ledger: Blockchain’s immutability means data once entered can’t be changed or deleted, creating a reliable record that can serve as a trustworthy source of information across all transactions or data exchanges, such as in a financial trade or a health-data exchange.

6. Better resource management

Optimised energy usage: By allowing smart devices and grids to engage in autonomous transactions, tIoT can enable a more efficient use and cost of energy.

Asset tracking: tIoT can enhance tracking for assets in the logistics or manufacturing sector by tracking them in real-time and allowing automated transactions, ensuring that there is minimal asset utilisation with little to no wastage.

7. Improved regulatory compliance

Automatic compliance: Sense and respond – tIoT works to contribute to organisations’ compliance with regulatory requirements, automatically, by means of local smart contracts that automatically enforce regulatory requirements. This minimises the risk of non-compliance and the sanctions associated with it.

Transparent reporting: All transactions are recorded in a blockchain, satisfying reporting to regulatory authorities and streamlining compliance.

Technological improvements and growing interest from industry companies indicate that tIoT has a potential to thrive in the future. Advancements in blockchain scaling and IoT integrations can address these issues, making the technology scalable and available to the masses.

Using transactional IoT changes how the different components of IoT solutions behave and are capable of interacting with one another. The use of blockchain allows for a high level of security, transparency and efficiency. Many challenges remain, but the future is bright, as improvements continue to address current limitations. Because of these advantages, and its promise to help many industries become more efficient, transactional IoT could very well be the backbone of the future digital economy.
