For me it is not clear how the authentication of products is guaranteed. But this remains an issue for all the existing supply chain related blockchain projects: how can you connect the physical world to a smart contract and prevent any possibilities of fraud and possibly without middle men?

I have stumbled into this project when I heard of their token airdrop bounty. After sharing some of their tweets and checking out their Medium archive, I browsed trough their articles I must admit I caught interest. After learning some more I decided that it was worth share this quick overview with you.

http://WorkChain.io first of all is a payroll service in cryptocurrencies. The product is already live, first payments on the platform have been made.

The platform supports various cryptocurrencies, like Ethereum and ERC20 Tokens, TrueUSD and the native currency WATT.

On the roadmap there are lots of other fantastic features for this project. For instance daily payments, or payment of every task performed will be established as standard, which is great for employees who usually wait for more than a month for their salaries.

Another great feature is the to put the CV on the blockchain, which means it is immutable and this feature on the other hand is great for employers, because job applicants can't lie about their professional background anymore.

Also there will be lots of third-party integrations and applications, for example a workforce management system, an identity provider, a time tracking system, a project management system and a skill validation platform.

Yes, there are more established competitors like bitwage or bitpay, but I haven't found any similar platform out there with such an abundance of features.

In my opinion WorkChain.io is one of the most promising blockchain projects lately. One of their biggest strengths is the Team.

The Co-Founders have already founded succesful companies in this field. Ryan Fyfe is the Founder and Former CEO of Humanity.com, a leading employee scheduling software and Ivan Petrovic founded WorkPuls.com, a company tracking time of remote teams. As obvious result, the before mentioned services will be integrated with Workchain.io and bring with them over a million users.

The Trakx.io Team is building what they call Crypto Trackers, what are known also as CTIs (Crypto Traded Indices). Crypto Trackers or CTIs want to be the ETFs of the crypto world, a basket of different digital assets that are traded on an exchange and represent a passive investment vehicle.

Crypto Trackers are an easy-to-use, low cost, and efficient way to take part in the cryptocurrency market. This is especially true for newcomers in the cryptocurrency scene, who want to diversify or have a stake in various coins or tokens. Most of them had only the choice to register at an exchange an buy the coins one by one. While doing this the faced a lot of downsides: risk of the exchange being hacked, coins losing their worth, fees for every transaction.

But now with Crypto Trackers, also inexperienced users will finally gain access to the crypto world. And they will have a lot of advantages: lowest possible fees, diversification of the risk, no need of technical know how.

Finally I would argue, that there is no need to await for the SEC to approve Bitcoin ETFs and in my opinion that isn't going to happen anyways. Why? Because institutions like the SEC are from a different time and worldview and they are going to loose importance because of the better blockchain technology.

There are strong advantages of Crypto Trackers over Bitcoin ETFs, that it is a very flexible instrument, that can invest in the crypto currency market as a whole, or in a select basket, instead of just focusing on Bitcoin alone. This will most definitely mean higher gain potential but as well better diversification. Even Bitcoin as the Gold Standard of the crypto currencies is not guaranteed to stay forever, especially as we all know of its drawbacks. By the usage of smart contracts Crypto Trackers enable a no trust investment vehicle.

Back to the project that will enable Crypto Trackers. Trakx.io is a promising Team which is working towards of the realization of Crypto Traded Indices, the ETFs of the crypto world. They are going to implement their own ERC20 token, smart contracts, a market oracle and plan to launch a highly scalable, decentralized exchange.

The Management Team of Trakx.io has a very strong background in banking, they know what they are talking about. As they bring their know how into this project, the end result will be the combination of the revolutionary blockchain technology with advanced banking solutions. Some of the planned features are automatic re-balancing, self auditing, long and short position instruments, leveraged basket Crypto Trackers.

Concluding I would argue, that compared to other projects Trakx.io might not seem as fascinating, but if we honestly examine some of the most interesting blockchain 3.0 projects, they are still very far away from any real world use case. Crypto Trackers on the other hand are definitely a real world use case, provided that crypto currencies are not going to disappear, which seems very unlikely.
