Is it getting harder to cheat the blockchain network?

If a transaction is made on the network, a computer writes it down, checks it and insert it into a block. It also notes when the block was created and which was the last block. So the first computer that has calculated a new, complete and correct block insert it into the blockchain. Then all members of the system check that everything is correct. So if the result is positive, he will be rewarded.

That is how blockchain secures the network. If you want to “break into a blockchain” and change something at least 51% of all nodes need to agree with you. If the network is big, it is harder to change something. So the more people are in the network, the safer it gets. Thus, it depends on how many members the blockchain has.

As more and more people get in touch with blockchain, more people join the big blockchain network. As a result, it is getting harder to “break into a blockchain”. So if you are talking about the major blockchains like Bitcoin or Ethereum, the answer is yes, it gets harder.
