Elk is the easiest way to start building decentralized hardware projects

No, Elk is meant to be a development board for multiple decentralized technologies. While Elk will initially ship with support for Ethereum and Bitcoin, support for additional blockchain technologies will continually be added. Additionally, some protocols that we support, like Whisper, Swarm, and our Elk app, don’t rely on crypto payments at all and you can use them without ever owning crypto.
