I was asking myself if it is possible to clone a coin 1:1, mine a lot of coins and sell them as real coins
For example i copy the sourcecode of SC nd mine those coins on my Laptop, since Im the only 1 mining this (clone, copy) Iit would be easy to mine lots of them
What mechanism prevents that from happening??
We all know the Federal reserve Bank has the right to print Dollars and in the Bitcoin System everyone can mine Bitcoin but what stops me -besides the knowledge- from cloning those coins and kind of faking them
Has anyone ever tried that??
No, since you would be starting a new blockchain.
Blocks are stacked one after another, and the newest block depends on the older blocks for validity.
If you were to create new blocks on your rogue chain, it would simply be denied since the your block does not match the previous block on the main chain.
