It's been almost 2 years since I first heard the name of Tau-chain, thanks to my brother 
What is Tau-chain?
This project created by Ohad Asor is really ambitious and aims to create the internet of knowledge.
Some people would label it as an Artificial Intelligence, but according to the creator this is something totally different. Summing up and to understand me, Tau-chain is a tool that knows how to interpret any information and deduce any consensus. This tool can be used in any field, judicial, political, academic, social, scientific and also without limits assembly from 2 people to a million for example.
A practical example could be for the professional field:
Imagine that a group of 10 people are discussing an important issue that involves your company. This debate takes place on a platform similar to WhatsApp or Telegram. Each opinion, comment, can be voted or discussed. All this information is analyzed by Tau-chain and little by little he understands how he thinks each of the people who are participating. After a week discussing the employees want to get a consensus of everything, then ask tau to make a summary of everything exposed and also tau gives them their most logical opinion (consensus) I have even suggested that the most practical way they can take.
Unot of the aspects that strikes me the most is that Tau-chain will have a "auto-comment" option. When you have been using it for a long time, you can request that tau comment for you, of course, it will always be a comment approved by you as a last resort.
The Tau-chain community
We can find a lot of information about the project on the web of IDNI.org but in parallel there are different groups of debates and chats where the project is talked about daily. [1]
A few months ago, the Logo contest for Tau-chain and Agoras was launched. And after a month of hard work from my team ( 
Today I am very proud to say that I am part of the project because I am the design consultant and I am in direct contact with all developers and consultants like me. We all want to see tau work and show the world its incredible potential.
