Agoras' XCP intermediate tokens at worth of:
1. $1500 will be rewarded to whom giving a winning common-people understandable definition of tauchain. The definition has to be simple, accurate, and give the listener an ability to understand what can be done with the system in strong sense (not only "change blockchain's rules").
I'm not a programmer so I don't really understand a lot of the whitepaper and I'm not sure whether I've got a right understanding from what I read or not, but $1500 is a good excuse to try and work out wtf you are doing with this thing so here is my attempt:
Tau Chain creates a network of computers which work together as a kind of distributed truth engine. Any computer within this network can submit a solution to a task which somebody wants completed, whether it is storing files, performing a calculation, or writing a piece of code to perform a specific function. The Tau Chain provides a flexible set of tools for the network to tell whether that computer is telling the truth about performing the task or solving the problem.
Through the inclusion of data about the meaning of words, and their relationships to each other - which has already been highly developed in a machine accessible way by search engine engineers trying to help computers to respond naturally to questions people type into places like Google, the Tau Chain would be able to apply the same logic to verify whether human statements are true or false, and to give people answers to logical questions.
This allows the Tau Chain network to perform a wide range of useful functions in a decentralized way.
In fact, it may well be the case that it is able to do these things in a more decentralized way than other cryptocurrencies such as Bitcoin, because no matter how collaborative an open source project might be, its development must ultimately have a central authority to lead the development. The ability to check whether code performs a required task may mean that Tau Chain users are able to propose and vote on features they want, put them out to tender, and validate any solution which is provided, all through the network itself without the need for a central authority.
Over time the network would build up a big library of pieces of code, each of which would have been proven to perform specific tasks. Eventually, it may even be able to combine these code fragments together itself to provide its own (artificially) intelligently designed computer programs.
In the same way, libraries of statements people have made, and whether they are true or false, might also be built up. This would allow the network to use the collective power of all its participants to answer ever more complex questions, and to embed the facts which it retains in an increasingly broad context, or meaning.
