What Is IOST Coin | A Quick Overview

IOST Coin is focused on something called the “internet of services” which is a decentralized solid infrastructure for online service providers. With high transactions per second, privacy protection, and scalability they see infinite possibilities for online service providers.

The History of IOSToken

IOSToken put out their first article on Medium on January 3rd, 2018 where they explained what the Internet-of-services is and the main concept behind IOST coin.

They launched not with a public token sale, but with an independent private sale that was an institution where China, Korea, and the U.S. were not allowed.

Otherwise, since then they have been in development, but do not have a full-scale working product yet.

The Roadmap of IOST Coin

The Purpose of IOSToken

IOSToken set out to fix a few issues in the crypto ecosystem.

The first being the fact that scalability and the increasing challenge for networks to join and handle a capacity of transactions on the blockchain is only increasing.

Secondly, they wanted to create a more fair and sustainable form of consensus.

That way the energy that is typically required for proof-of-work mining isn’t wasted, and proof-of-stake can’t be manipulated.

What they came up with is IOSToken and its proof-of-believability type of consensus (which we will get into in the features section).

And together, the way that IOSToken operates is connecting these service providers to serve their customer base ultimately.


The Features of IOST Coin

Improved Scalability Using Three Technologies


Partitioning state for multiple groups handled in parallel.


An atomic-swap protocol that helps enforce consistency among cross-shard transactions.

BRDR - Bias Resistant Distributed Randomness

This is one of the ways that the IOS network will be more fair, by introducing unbiased randomness into the network.


Based on contribution to the network, the behavior of the node, and a default inputted randomness; this creates a consensus mechanism that anything can use.

It is a way to fight against the energy that proof-of-work costs and the systems that proof-of-stake can create.

It uses an intrashard believable-first consensus mechanism. These believable validators process transactions quickly in the first phase. The believability score is made from token balance, contributions to the community, reviews, and many other indicators.

Then in the second phase, normal validators sample and verify the transaction.

And after the rest of the process takes hold, the transaction is complete, and the consensus is achieved.

The IOSToken Ecosystem

iost coin system
This is a triangle based system of intercommunication between the IOST network.

HUDS - A way for the IOS ecosystem to provide a decentralized, secured, searchable, efficient and economical storage mechanism.

dApps and Smart Contracts - The centerpiece of the ecosystem, allowing developers to have the stability and high concurrency from the IOS virtual machine and develop in mainstream programming languages.

Fair and Transparent Feedback System - Being fair, they want to allow users to provide feedback on the service. This is then designed to be verified feedback and honor the believability of the system.

What We Think of IOST Coin

On a large scale, IOST coin is aiming to create a network meant specifically for service providers and addressing their concerns.

The proof-of-reliability algorithm trips us up though, as it is trying something completely new without prior testing and with no working version.

As the product is released, we will be able to see if the PoB model holds up or not. For service providers and their customer's speed, scalability, and trust are crucial. And that is what IOST coin seems to be trying to accomplish.

Otherwise, we do not currently hold this coin and will be looking at it in the future.
