IoT development is impossible without creating a decentralized environment. Linking devices to remote servers of IT companies is the initial, not the last stage in the evolution of the Internet of Things.With the growing number of devices, the centralized model shows its weaknesses: insufficient bandwidth and vulnerability of data passing through the servers. The answer should be to build a multi-agent system, each participant of which is endowed with greater autonomy and is able to perform a wider range of tasks. We are talking, about the ability of a device to independently accept orders and pay for their execution, as well as to enter into a contract with another device without human mediation.Ethereum smart contracts make it possible to implement such a concept, but only to certain limits \u2014 due to limited bandwidth, high cost of transactions, and the lack of a common language with other blockchains-unless the developers have come up with a special bridge for a specific case.Polkadot, the flagship project of Parity Technologies and the Web3 Foundation, a sharding protocol that allows inter-blockchain communication, has a better chance to implement the idea of Web 3.0 and open the possibility of connecting millions of smart devices to the global network. Below we will analyze the reasons why the IoT sphere has become one of the main beneficiaries of inter-network protocols and consider the most promising IoT projects on Polkadot.The update of the Ethereum 2.0 network, launched in the zero phase at the end of 2020, should open a number of functions due to the Proof-of-Stake consensus, and in the future, when moving to the next phases, it would deploy an experimental model known as sharding. In fact, it will be 65 new blockchains: the existing one from the zero phase of the Beacon Chain and 64 new shards\u2026<\/p>","protected":false},"excerpt":{"rendered":"
