Meet Troika — A Hashing Method Fit For IoT Blockchains?

When there’s a new crypto method, it’s like an early Christmas present for me. And so the Troika hash takes to the stage. It has been designed to integrate with the IOTA distributed ledger, and aims to be one of the most secure and energy efficient methods around. Before I outline it, we need to understand why we need a new hash signature, and why we need one that is fit for IoT devices.

Why?

One of the greatest challenges that we have on the Internet is the scale-up of devices within an IoT era. For this organisations may have millions (or even billions) of devices which must be monitored and controlled, and then discover the current state of the overall network infrastructure. Most existing system would struggle at a large-scale to create a current consensus of the infrastructure, but IOTA -with its Tangle engine — can report on the current state, along with previous states [here].

Along with scale, the greatest challenge in a world of IoT devices is that we can often have devices with limited capabilities. This might related to the number of transistors that can be supported on the device, or the amount of memory. But the greatest challenge is often energy consumption, and where we have device that have extremely limited power drain capabilities. For this we cannot use our existing…
