Bitcoin uses a digital technology called “blockchain,” an advanced coding mechanism that
disperses a single code over thousands of different computers. For example, let’s say that
your coin is built from the code, “XDA146DDS.” Blockchain segments the code into smaller
pieces and stores the pieces of code across many computers. If a hacker wanted to access the
code, they’d have to hack various computers to access the entire code.
Blockchain also employs a “public ledger,” which uses thousands of computers (referred to as “nodes”)
to keep track of coins and their owners. If a coin’s data is changed, the nodes will cross-reference
each other’s records to verify whether the change is accurate and that the coin’s owner initiated it.
