Apparently, it can be very secure. If “pieces” of a secure key are stored in multiple places, for example, only changing one link in the “chain” means it won’t match with the others. They ALL have to be changed at the same time, which is virtually impossible to do in secret.
Please note that I am far from an expert on the subject. I’m paraphrasing an article I read months ago.
Can’t you takeover a blockchain by owning the majority of a block chain, or by having a majority of the processing power to compute hashes?
If you had 51% of the world's computing power (to blockchains using proof of work) yes you could forge records, from what I could wrap my head around about blockchains.
You don't need 51% of the world's power though, just 51% of the power of people who care about how the system works. Most people using block chain cryptos don't care at all, so the threshold is a tiny percentage of the user base.
Yeah you're right. I was thinking specifically Bitcoin and the astronomical amount of compute power that's behind it.
That’s proof of work. Proof of stake is you just need more than everyone else, right?
It works more like loaning money and then receiving interest, except you are loaning crypto to the network and then you get it back, plus some, after a certain period of time
Is the network not considered a third party
