What type of Challenges would you like to see more of going forward?
A significant percentage of people have heard of cryptocurrency, of which the most famous bitcoin
(https://en.wikipedia.org/wiki/Bitcoin). Fewer people understand what's inside blockchain which is a key element of any

cryptocurrency https://en.wikipedia.org/wiki/Blockchain_(database)
Is highly probable that the importance of cryptocurrency will increase in the future. It is therefore desirable to extend the

understanding of their internal structure.
I offer the GrabCAD community a challenge: designing mechanical analogy of blockchain.
Preliminary description (in brackets are the original definition of blockchain)
Each unit is a drawer filled with any number of of any shape objects (block and transactions). The box is provided with inlet

and outlet locks (hash of the previous block and the current block) . In case of coincidence of the output lock of the

previous block to the input lock of current box they are closed. Lock works only once and can not be opened.
The first box is rigidly fixed to the wall, the location of its output crossbars lock by accident.
Number of crossbars of locks may decrease and increase (difficulty).
In the box, you can add and remove a limited number of items (nonce)
In my humble opinion the problem is interesting because we will not have to deal with determinate system, and with the

statistical mechanical system. Such systems will evolve (genetic algorithms and neural networks are driving flocks of drones for example).
Questions and comments are welcome!
