Blockchain of things is the fusion of blockchain and the internet of things. BCoT is an important milestone in the blockchain technology that ensures the security of IoT controlled devices. The future really lies on IoT devices which makes our real-life environment a more technological environment. Blockchain of things comes up with an idea of integrating the blockchain and IoT altogether to make the undisputable tech combo. The blockchain implementation in the IoT field helps to record the important data as immutable one. The blockchain of things is practically possible in a bit technical way.
The IoT devices are simply sensors which are connected to a Rasberry Pi module. So the role performed by blockchain over IoT devices is the collection and contamination of data generated by the IoT sensors.
The IoT sensors transmit data over the HTTP/MQTT protocol to the Rasberry Pi. The blockchain acts as the medium between these two modules. The blockchain receives the sensor data in JSON format and transmits the data to the blockchain smart contract. The smart contract push that data in the corresponding blockchain in JSON format. After data gets entered into the blockchain the data is passed to the Rasberry Pi.
The entire IoT enabled device data is getting transferred to the blockchain through MQTT protocol.
Advantages of BCoT:
- It makes IoT more efficient and error-free
- It enables high-speed data entry with long time record-keeping
- It filters the data in FIFO(First In First Out) order
- Its makes IoT data tamper-free
The blockchain of things makes the IoT device and Rasberry Pi a trusted one and also helps the IoT devices to work in a convenient and safer way.
The IoT has unleashed large monetary benefits and also transformed human life. However, the lack of security measures has put an end to the developing trust for IoT technologies. Blockchain is a distributed ledger technology that allows data to stay tamper-free for a lifetime. So the term blockchain of things comes up to address the critical challenges faced by IoT. The integration makes a whole new world for the tech industry. The unalterable consensus mechanism of blockchain
Blockchain and Internet of Things (IoT), is considered as the two most rated developing innovations. So, IoT and blockchain are complementary to each other and solve the issue which both carries
The blockchain of things has been stared by 2014 by blockchain and cryptocurrency experts with an idea of tackling the challenges faced by the IoT. The record-keeping facility of blockchain has been a great solution for IoT technology. The issues faced by the IoT can be easily solved by integrating it with blockchain. The limitation of the blockchain of things is given below.
Disadvantages of BCoT:
- Both techs are immature
- Blockchain may be costly compared to normal database
- The integration may slow the process of data readability
- The entire system may act as a complicated circuit
Features of Blockchain Technology:
- It’s an immutable ledger of data
- Its tamper-free from any attacking
- Its keeps the data in multiple systems as chronological chain
- It can be public or private in nature
- Its stores the data for a lifetime
- Devices and sensors are interconnected
- The data is transmitted through Rasberry Pi
- The sensor transfer the data in simple JSON format
- The data is processed by the single module called Rasberry Pi
The Blockchain of things is slowing moving forward to become the future of technology. Everyone is doing research on implementing the blockchain and the IoT altogether into new advanced technology. The integration can also build an era of technological advancements and automation, where all the devices are interconnected as same as the internet. The data generated by this technology will be much higher compared to the existing technology, but it is opening a pave to the next advanced generation. The smart homes can be maid by simply integrating all devices inside a household with the blockchain of things. The smart home will detect the presence of the house owner and activate all sensors and act based on individual choice. Blockchain will be an added advantage where all the action of the house owner gets stored with proof and its tamper-proof technology makes it’s unique from the traditional cloud storage.
