Smartshare is developing a blockchain-based network to connect devices in the Internet of Things. Smartshare's distributed network protocol uses blockchain and smart contracts to enable exchanges of data between devices on their network. Smartshare is powered by the Ethereum-based SSP token.

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.
