- Blockchain has a major role to play as the Internet of Things becomes one of the defining technologies of our time, and some, like IOTA, Chainlink, and VeChain, are taking the lead.
- IOTA was developed with machine-to-machine communication in mind and is the industry leader, while Chainlink’s interoperability is a game changer.
The Internet of Things has become one of the most transformative technologies of our time. Studies suggest it could add between $5.5 trillion and $12.6 trillion to global GDP by the end of the decade. Today, there are more than 15 billion interconnected IoT devices, from smart home appliances and wearable technology to self-driving cars and industrial sensors. That number could triple by 2030, according to the latest studies.
Beyond statistics, IoT has a real impact on the quality of life. These devices improve efficiency and automate most processes, reduce costs by reducing downtime, provide real-time data and insights for better decision-making, offer a better customer experience through personalized services, and open up new business models and economic opportunities.
While IoT is a transformative technology, it still needs to integrate with other technologies to optimize performance, security, efficiency, and privacy, including blockchain. Today, many IoT projects rely on blockchain to secure their endpoints, verify and protect data, improve machine-to-machine microtransactions, and more.
Blockchain and IoT
The world of blockchain is vast: there are more than 10,000 cryptocurrency projects today, and many of them have their own blockchain network. However, only a few have managed to break into the IoT market.
IOTA is leading the pack. The network was built with machine-to-machine interconnections in mind, as founder Dominik Schiener told CNF. One of IOTA’s greatest strengths is its ability to effortlessly scale to handle very high throughput thanks to its Tangle technology. With over 80 billion IoT endpoints this year, only a massively scalable blockchain technology can handle the workload. While some networks like Bitcoin handle certain functions, like storing value, extremely well, they are not equipped for these scalability requirements.
Additionally, IOTA offers fee-free transactions, and with billions of messages expected to be sent between IoT devices daily by 2030, the cost of each transaction would be astronomical. IOTA’s decentralization, low resource requirements, and data integrity also make it uniquely positioned to handle IoT.
Chainlink is another blockchain network making its mark in IoT. One of Chainlink’s greatest strengths is its interoperability solutions. Today, CCIP is the world’s leading blockchain interoperability solution, connecting dozens of the largest networks, with new applications integrating every other day. Additionally, Chainlink’s decentralized oracles connect blockchains to off-chain data, which includes data generated by IoT devices. Essentially, integrating blockchain and IoT is nearly impossible with Chainlink.
VeChain is also becoming a major player in blockchain-IoT integration and has accumulated important patents for the sector, as we have reported.
