No one can cheat the blockchain. Every transaction is confirmed by the blockchain users. It is impossible. If someone were able to cheat the system, then bitcoin wouldn't exist by now. He would destroyed the whole system and probably he will be rich. (9.000.000.000$ rich)
I TOTALLY agree with you. Blockchain can't be bluffed/cheated into creating a transaction out of nowhere, it tracks every single transaction made and if someone was able to cheat it, the bitcoin would drastically drop in value, so the whole system would collapse/crash. No one would benefit from doing such thing! 
Topic: How if everyone cheat the Blockchain? (Read 2034 times)
I know that if just 1 people do it, it won't possible because the miner will check the transaction.
But how if everyone tries to do it, I mean like how if they add all of the Bitcoin address a 1 Bitcoin. Would the miner think that those are valid transactions because all the ledger have those transactions in it?
Honestly dude, let's bes serious here. I do not think blockchain can be cheated and nobody AFAIK has successfully do that. With the large population of adopters, I guess they have tried that before and none of them had succeed.But how if everyone tries to do it, I mean like how if they add all of the Bitcoin address a 1 Bitcoin. Would the miner think that those are valid transactions because all the ledger have those transactions in it?
The system is safe that's why we trust it.
I think what you're trying to say is that cheating the blockchain means creating transactions or hacking it? Cheating it that make you think you have bitcoin in your address? No matter what it is, it's very hard to cheat or force a transaction or something on the blockchain. It is called a blockchain for a reason, connected blocks with timestamps written all over it. It's not easily tampered even if everyone would cheat or tamper it. It won't ever happen because it's impossible.
Is that so?

I think that It is impossible, although it can be a small possibility because if we want to log in into blockchain we need to be authorized for your email and coupled 2FA code that makes it more secure again. 2FA code will be sent to your number phone which only you know.
OP is talking about cheating bitcoin blockchain by so called 51% attack not cheating blockchain.info wallet you are talking about. 
I don't think we will have anything like this type of attack on bitcoin which can easily reverse the transaction/block or even modify the bitcoin from addresses, you can check about 51% attack on krypton and shift to know how this affect the network however those are ethereum based/clone.
If every miner were to defy the protocol rules and generate 100BTC per block or include transactions with inputs that were previously spent, the reference nodes will just ignore you. If you were to create to something that defies the rules, you would be creating another coin.
Bitcoin is designed such that the user decides what they want and what they don't. If everyone wants Bitcoin to generate 100BTC per block, they have to modify their software and those who agree will have that block reward.

You're pointing in the direction of a 51% attack. This, sadly is a flaw when it comes to Bitcoin and most decentralised networks in general. Sure, one malicious node in a sea of legitimate nodes will get drowned out, but what if the majority are malicious nodes?
A 51% attack is when a single entity or a party with a common goal that is not beneficial to the ecosystem takes control. This is commonly linked with mining hashpower. This will allow the malicious group to have near-free reign of which transactions to allow and which to block. This could cause massive disruptions.

I dont think you really understand bitcoin very well asking this question, i would go and read abit more. bitcoin.org
Satoshi developed the protocol to force people to stay honest, because it is in their best interest to do that. IF a bunch of miners or a pool managed to do this once, then the whole integrity of the network would be compromised and the people using this currency will abandon the experiment by selling their coins.
They will be left with coins of zero value and they will also not be able to mine anymore. Why would you want to do that?

Why do you say everyone ? It will never be that everyone does the same thing. No we even listen to different music or like different altcoins. If we were all the same it would be very boring. Bitcoin has in place preventative measures so that it is impossible to cheat the blockchain, By the very nature of how it works. If everyone could do what you talking about then how could bitcoin ever work ?
It requires too much of resources and money to do a 51% attack and why? when they can make money with using such resources why would anyone wants to disrupt the process?
And since the pools are being distributed all over the globe then would be very expensive and not much to gain instead.

How can we cheat blockchain? I think no one can cheat blockchain. before it was launched i think they already study all the aspects especially when it comes to hacking and cheating them. But if someone can definitely do that, he was so really lucky enough to become rich.
Yeah, I agree that no one can cheat the blockchain since it is designed in a very secured manner that no one could make any cheat on it. According to an article by Jonathan Cross (2015), "Each block builds on the previous block like a "chain", except that every time a new block is mined (added to the end of the chain), the security of all blocks which were mined before it increases. Every block created makes it dramatically harder to rewrite history because anyone can verify the history is correct when looking back in time to the very first block ever created."
I know that if just 1 people do it, it won't possible because the miner will check the transaction.
But how if everyone tries to do it, I mean like how if they add all of the Bitcoin address a 1 Bitcoin. Would the miner think that those are valid transactions because all the ledger have those transactions in it?
What?But how if everyone tries to do it, I mean like how if they add all of the Bitcoin address a 1 Bitcoin. Would the miner think that those are valid transactions because all the ledger have those transactions in it?
This isn't even coherent English, sorry bud. I'm lost but I'll try to do my best when it comes to this.
You can't add 1 Bitcoin to every address unless you have that Bitcoin or fork the network to give everyone 1 Bitcoin, and if you give everyone a Bitcoin, then the value drops considerably, potentially even destroying the value.
The miners would not have a say in a fork, as it would be moving to a different blockchain, but they would not be obligated to change the chains either.
Could 51% nodes attack be mean if bitcoin has got a geopolitical attack?
you are talking about 2 things.. geo.. and politics
firstly. geo
28% of nodes are in america.. lets say america systematically cut off the internet right at the ISP of 1500 ISP customers..(yes its possible)
it wont really harm the network as there are still other nodes spread out in 90 countries. so the blockchain is still distributed.
secondly..political
4400 of 5400 (83%) are running bitcoin core of different aged varieties (27% running latest version of core)
lets say there was a known bug in core.. or a trojan in core since version 0.8 that has a political reason to be there to activate when core decided the time was right.. 27-83% of nodes can get affected.
its not just about geographic diversity.. but also the implementations need to be more diverse.
3 main groups. or 8 total groups is not enough diversity
especially when core devs have been very loud about getting other implementations to fork off so that core can dominate bitcoin
The other, If I were getting some was saying the 51% hash attack, it could be called a political attack, And according to your explanation, it means the political attack of bitcoin has centralized on the bitcoin nodes.
I may think if it was getting an opposite thing, or it will be becoming one direction way.
Although the chance for reject and accept the bitcoin transaction, it could have done by them(nodes attack). It is building the opinion if Hash 51% was not mean something.
Even the Nodes attack are more dominant.
I know that if just 1 people do it, it won't possible because the miner will check the transaction.

It`s impossible "everyone" to cheat the blockchain.
I don`t know why are you asking this?
It`s a pointless hypothesis.

I am a bit do not understand with OP question
if there is, that I can be sure bitcoin will be destroyed.

There's no why and how in this...
If people find a way to cheat the system the coin will be dead...
About the 51% attack, if you have this power of mining, you will never want to be the coin dead, to you will reduce your power because you have an golden egg.
