I don't know when I started to think that banking was going to be a bad day, and that the old banks would collapse sooner or later. Bankers have historically been rich owners just "maxi" haha until you learn about blockchain technology and then further see a meaningful word from Nakamoto "The Times 03/jan/ Chancellor on brink of second bailout for banks "(the main idea: January 3, 2009, the Chancellor of the Exchequer stood on the edge of the second b

Bitcoin requires each block to prove that it has put enough effort into creating them to ensure that malicious nodes that want to tamper with historical chunks of information will have to pay more for the effort, rather than simply modifying a single record-proof of workload.Chaining the chunks together (hash-linked) makes it impossible to modify only one transaction without modifying all subsequent trades. Proof of workload (Proof-of-work) Use SHA-256 to hash a value to see if the result has th
