Is Blockchain the answer to IoT security
A key challenge for the Internet of Things(IoT) is security. There is a myriad of devices, each different from one another in an IoT ecosystem. This makes securing each device challenging as there is no one fits all approach. In recent years, IoT ecosystems have been overwhelmed by DDoS attacks. A distributed denial of service(DDoS) attack overwhelms the IoT networks with huge traffic. IoT ecosystems have hardware constraints due to which it becomes difficult to prevent such attacks. Added to that, since all the devices are connected, the attack spreads throughout the entire system leading to massive consequences. Blockchain is basically a distributed ledger in which records of transactions are made by many nodes. It is a decentralized system in which no one can alter a particular transaction. If a wrong transaction is made, a new transaction must be created to reverse the error, and it is visible to all the network participants. You may have heard of blockchain related to c...
