Why the Future Internet of Things Depends on Blockchain
The internet of things IoT has been associated with major cyberattacks , often involving the abuse of vulnerable connected devices, such as surveillance cameras, to facilitate malicious activities.
In principle, it would enable protection of IoT networks in a number of ways , such as forming a group consensus on aberrant network behaviors and quarantining any nodes that may be performing irregularly. Within several decades, the IoT has significantly expanded its reach and connected numerous devices and networks in homes, workplaces, transportation systems, and even entire cities.
The decade-old blockchain, on the other hand, is set to revolutionize business models through its encrypted and distributed ledger designed to create tamper-proof and real-time records. With the IoT and blockchain working together , the latter is expected to provide a verifiable and secure recording method for devices and processes associated with the former. Blockchain works as a distributed ledger, where every deletion or modification of data is recorded, and as more entries, aka blocks, are put into it, a longer chain of events is created.
Each transaction made is accompanied by a digital signature and can never be changed or deleted. We have noted that in securing smart cities , such an expediency is crucial to maintaining connectivity and functionality in services, especially for critical systems. With blockchain, each device will have strong cryptography, further ensuring secure communication with other devices and affording anonymity in IoT use cases where privacy is of utmost concern.
Adopters will have the ability to better track devices and distribute security updates, helping to fortify potentially vulnerable devices. Figure 1. Blockchain in the IoT: Potential benefits. The merging of blockchain and the IoT is also expected to address the issue of oversight. In businesses, for instance, transactions made by multiple sources can be administered through an immutable and transparent record, where data and physical goods are tracked throughout the supply chain.
In the event of an erroneous decision or system overload, the blockchain record should be able to identify the point — say, a device or a sensor — where something went wrong, and the business could take immediate action. Blockchain could also help reduce operational costs since it eliminates intermediaries or middlemen. Blockchain is more than the distributed ledger technology underpinning cryptocurrencies, most notably bitcoin. In fact, it is already being used in different industries, including in retail to simplify as well as secure the movement of products through supply chains and in pharmaceuticals to ensure the integrity of contracts, clinical trials, and the drugs themselves.
With the integration of blockchain into these and various other sectors, quality levels of products and services are closely monitored. In the IoT sphere, blockchain has been gaining traction as well. A blockchain-protected security platform for the industrial internet of things IIoT is already being offered by one company.
A blockchain-focused research center has also been formed to promote the development and commercialization of the technology and its capabilities to revolutionize the IoT ecosystem.
Blockchain in the IoT is indeed gaining momentum, but not without a few roadblocks. For one thing, the key concept to blockchain is the series of transactions that have been made and how they form a chain.
The chain is created by keeping a reference of previous transactions, hence the blocks. However, blocks are computationally intensive to create, taking multiple processors and significant time to generate. Since a single block is difficult to generate, tampering with it would be similarly tough: One has to tamper with the previous block and follow the chain created so as to change it completely.
This setup seems to be ideal for securing the IoT. However, the caveat is that IoT devices are relatively underpowered and underlying blockchain protocols create overhead traffic , with the generation of a block introducing potential latency.
In terms of security risks, researchers have classified threats related to accessibility, anonymity, and authentication and access control. Malicious actors may threaten accessibility by preventing users from accessing data or services through such means as denial-of-service DoS attacks and cloud storage compromise. They can also try to pass themselves off as legitimate users to gain access to data, although threats against authentication and access control can be detected since all transactions are recorded and verified by users in the chain.
Additionally, in our security predictions for this year, we forecast that blockchain will be exploited by threat actors to expand their evasion techniques. It is also not far-fetched to conjecture that IoT sensors and devices can be compromised to transmit wrong information to a blockchain.
By virtue of the technology, if an entry is authenticated, it will be recorded in the chain. Adopters therefore need to ensure that sensors and devices have overrides at the ready in the event of a compromise and to grant access only to users who should be in control.
When run properly, blockchain can greatly benefit IoT systems by decreasing costs and pushing efficiency. For example, up to only 10 percent of production blockchain ledgers are expected to incorporate IoT sensors by Moreover, there still is a long way to go before most IoT systems become computationally competent enough to handle bulky blockchain implementations.
While the elimination of the single point of failure has yet to be realized, securing the IoT still lies in the continuous deployment of security for all connected devices.
Aside from timely software updates to prevent downtime, what IoT adopters, individuals and organizations alike, should look into is multilayered security with end-to-end protection, from the gateway to the endpoint, capable of preventing any potential intrusions and compromise in the network.

Blockchain adoption in IoT
In one sense, this is a different position from more popular Blockchain use cases in financial services, provenance, supply chain, health care records, corporate action, property rights, crypto currency, and numerous others. In another sense, there are fundamental similarities. Records, Contracts. All these and more are characteristics of common Blockchain use cases. Including IoT.
Blockchain IoT: The Next Big Thing to Excel in Advanced Technology
All devices are identified, authenticated, and connected through cloud servers that sport colossal processing and storage capacities. Connections between devices have to go through the internet, even if they happen to be a few feet apart exclusively. While this model has connected generic computing devices for decades and will continue to support small-scale IoT networks as we see them today, it will not be able to respond to the growing needs of the vast IoT ecosystems of tomorrow. Existing IoT solutions are expensive because of the high infrastructure and maintenance costs associated with centralized clouds, large server farms, and networking equipment. The sheer amount of communications that will have to be handled when there are tens of billions of IoT devices will increase those costs substantially. Even if the unprecedented economic and engineering challenges are overcome, cloud servers will remain a bottleneck and point of failure that can disrupt the entire network. However, establishing peer-to-peer communications will present its own set of challenges, chief among them the issue of security. And as we all know, IoT security is much more than just about protecting sensitive data. The proposed solution will have to maintain privacy and security in large IoT networks and offer some form of validation and consensus for transactions to prevent spoofing and theft.
Block Chain and IoT: Why They Need Each Other
Over the years, IoT has received much praise from both large enterprises and individual consumers. However, the mass adoption of this new technology gives rise to many security concerns. The San Francisco-based IoT conference, Internet of Things World, surveyed over IoT enterprise leaders and revealed that security and implementation are the top two categories of challenges for the technology adoption. But first, what exactly is wrong with the existing security architecture used by IoT manufacturers, and is there a way for internet of things developers to address is effectively? This allows people to use their devices easily from anywhere in the world.
