Connected Devices & Services

By connecting smart devices to a blockchain – from smartphones and computers to internet-enabled cars, smart locks, advanced manufacturing machines, and security systems – we can facilitate marketplaces, payment services, or even a sharing economy for the Internet of Things. This makes possible not just peer-to-peer transactions, but even machine-to-machine payments for services, from tollbooth payments to battery storage, consumption, and trading. Best of all, because these interactions are on a blockchain, they will not rely on financial intermediaries or be subject to the security risks inherent in centralized data storage systems.

The value of blockchain networks is limited if users cannot easily access them. As Blockchains remains committed to developing products and solutions to enable an accessible, secure entry point to Web 3.0, our blockchain connectivity client, IN3, allows internet-enabled devices to easily and securely connect to blockchain networks with minimal bandwidth.

Earning its name as a stateless verifying ultra-light client, IN3 (INcentivized Node Network, pronounced “in-cubed”) is the smallest client launched to date, only needing about 300kb of storage, making it easy to integrate into IoT and mobile or web applications. The IN3 client is a crypto-economic, non-synchronizing, and stateless blockchain client with minimal resource requirements.

The emerging connected world and sharing economy

Today, the Internet of Things is quite fragmented and unsafe: Machines do not have wallets or a digital payment system to facilitate transactions, and there are high-security risks when it comes to interoperability.

IN3 allows devices of any size to access blockchain data securely, take payments autonomously, and interact with humans, machines, and anything in between – enabling the sharing economy and economy of things.

Interacting With a Blockchain

Interacting With a Blockchain

It is not necessarily easy to get devices, IoT or otherwise, to interact with a blockchain. Current blockchain connectivity solutions lack the ability to easily gain access to a secure and decentralized blockchain while maintaining the interoperability of devices and services. Right now, this requires significant processing power and space to download the entire history of a blockchain onto a device, or the use of remote services rely on centralized third parties, where security is not guaranteed.

Connectivity For Applications

Connectivity For Applications

The IN3 embedded client connects in a fully decentralized manner to the Ethereum blockchain and can verify and validate information without being part of the blockchain's peer-to-peer network. Responses are verified by proofs delivered by other nodes, or computers, in the network. Because the client is stateless – it does not need to sync with, or download all the data from the live blockchain network – minimum bandwidth is required for the transmission of information, and the interaction with the blockchain can happen immediately (no wait time).

Connectivity For IoT Devices

Connectivity For IoT Devices

Blockchain technology provides an immutable record of transactions on a network and allows for an additional programming layer to be applied on top of it for self-executing agreements between parties, or devices. When paired with IoT, IN3 allows devices such as wearables or appliances to communicate with each other, vehicles and charging stations to interact autonomously, or blockchain-based applications to fully function on a mobile phone.
