The Xensor token is used to power the Xensor IoT network. It is designed to connect IoT devices and to facilitate the automation these interconnected devices. The Xensor token is Ethereum-based and is designed to enable a market for data for a variety of hardware.

Filament develops hardware and software solutions that allow machines and devices that are connected to the Internet-of-Things to securely interact with a blockchain. Their products leverage the decentralized transaction capabilities of blockchains to better connect these devices and allow them to transact in new ways. Filament offers both external hardware as well as software for embedded devices connected to the IoT.

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.
