Yes! By the non-mining full nodes validating everything in the network.

thirdprize, full nodes order blocks from the miners, if they're invalid, they will be rejected. All the miner's work will then be wasted.

If a mining pool controlled 51% of the network, they will be able to put through a fake transaction from one address to another. This will pass validation as there is no double spend, no block errors and the nonce is valid. Eventually, by controlling 51% of the network, they will be able to produce the longest chain, thus making it technically valid.

Of course, the community can choose to thwart this by opting for a fork before the affected block, but this is another topic entirely.

that's not how bitcoin works!
it doesn't matter how much hashrate you own, even if you control 100% of it you still can not insert an invalid (fake) transaction in the actual blockchain that everyone else stores because it simply will be rejected right away by the rest of the network and you will be on your own, alone on a chain that you and you only think is valid.

Newbies are either misinformed by trolls, or haven't done the proper research. Plus when the trolls get to them first, it's hard for the newbies to believe that they're wrong.

@Wind_Fury
I'm going prove you wrong. By admitting I'm wrong. Haha.

@pooya87
Thanks for calling out the error. I hope to understand better now.
