Lets suppose Bitcoin transactions will not happen unless are made with real ID and real name, what we have to modify in Bitcoin transactions to me make it works?
Homework Answers
As bitcoin and many other cryptocurrency works on the idea of ledger transaction process - the idea of implementing digital signatures with private and public key distributed simultaneously so as to prevent it to expose. A private key is also known as secret key is kept with the users and shall remain a secret, however a combination of this secret key(256 bit) and public key makes it unique to a particular user - hence it can not be forged.
hence two functions can be implemented : signature and verify.
signature - (message+secret-key)
verify - (message+secret-key+public-key)
in this way only signed transactions are allowed - and use of an ID or name can be avoided.
Subsequently we have to hash these transactions into a ledger or a chain of blocks which can be mined by a miner outside the transactions - as they listens to it and then rewarded with block rewards (basically some amount of cryptocurrency) at the end and basically solidify and transaction made by the user - this phenomenon gave birth to what we know as Block chaining.

My bike is worth $M to me and $Y to you. Unless I buy a fancy lock that costs $F, you are able to take my bike. Suppose that M > Y > F. Suppose that I have a property right over the bike. That is, you may not take the bike without my permission (or you'll go to jail for a million years). If there are no bargaining problems, what outcome do we expect? I will pay you an...

My bike is worth $M to me and $Y to you. Unless I buy a fancy lock that costs $F, you are able to take my bike. Suppose that M > F > Y. Suppose that I have a liability right over the bike. That is, you choose whether or not to take the bike, but you must compensate me for the consequences of your choice. However, there are litigation problems. In particular, the court mistakenly believes that my bike...

Suppose we made a different graph with of Etotal vs.t, where is just sometime when we measure Etotal next. What would happen in this case? Will the graph be a straight line this time? What sort of slope will it have? HINT:look at Equation (6) and consider what the difference between (Etotal)final and(Etotal)initial would be at some tinitial and tfinal would be as ∆E/∆tis the slope, this time. Does Etotal change ast changes? What does this tell us about energy...

2. Sometimes you want to sort lots of data, but you only need the smallest (or largest) K items instead of all items. For example, maybe you want to give awards to the ten students with the best GPAs. If you have thousands of students, you could waste time sorting all of them just to find the top ten. Perhaps we can adapt an existing sorting algorithm so that it works faster if we just want to find and sort...
