Litecoin mining difficulty explained in details
Now, say Bob wants to pay Carol one bitcoin. Solving that problem is a lot easier than solving the block itself, but doing so gets the pool closer to finding a winning nonce for the block. How can you make every bitcoin exchange completely transparent while keeping all bitcoin users completely anonymous?
The proof-of-work problem that miners have to solve involves taking a hash of the contents of the block that they are working on—all of the transactions, some meta-data like a timestampand the reference to the previous block—plus a random number called a nonce. But the force that really makes the entire machine litecoin mining difficulty explained in details is pure capitalistic competition. If the ledger is totally public, how do you prevent people from fudging it for their own gain? What bitcoin miners actually do could be better described as competitive bookkeeping.
This item has been corrected. Say Alice wants to transfer one bitcoin to Bob. But because mining is a competitive enterprise, miners have come up with ways to gain an edge.
