Internet Node Token is developing a blockchain platform for the Internet of Things. The Singapore based company has created a router that connects household IoT devices. The Internet Node Token network is powered by the Ethereum based INT token.

AnyLog is making a decentralized IoT platform that will allow data owners to leverage the full value of their data.
AnyLog's technology attempts to manage the complexities of IoT data, to allow applications to immediately leverage it for a variety of uses. collect, store and query IoT data. AnyLog's blockchain platform aims to facilitate data monetization for devices in the internet of things, as well as a solution to collect, store and search IoT data.

IOTA was specifically designed to manage transactions for the rapidly growing network of devices that are connected to the internet. Instead of focusing on peer-to-peer transaction, IOTA aims to create the underlying infrastructure that will allow self-regulating transactions to occur between machines (watches, refrigerators, TVs, cars, etc.) on the Internet of Things.
Although IOTA cannot be strictly defined as a blockchain protocol, it uses a distributed ledger protocol called a Tangle, that has many of the same trustless features, but is fundamentally different because it has a different data structure that does not depend on blocks. The IOTA Tangle is a decentralized architecture with no transaction fees and no limitations on the amount of transactions that can be confirmed.
IOTA has several innovative features that are aimed at solving the scalability problems of blockchains. The Tangle drastically improves transaction times and reduces the storage requirements that are typical of other decentralized transaction protocols. This is achieved by removing the necessity of miners to confirm transactions, and making validation an intrinsic aspect of using the platform.
