Fundamentally, how does blockchain technology work (make sure you include concepts such as blocks, hash, etc. in your explanation)? - โ โ On the network, the record is combined with other transactions into a blockโlike a traditional computer database.

So all information is sequential, which helps avoid duplicate entries.The completed block is sent out across the network, where it's appended to the chain. The key to a blockchain's security is something called a hash. It's a bit of cryptographic math that makes the links between blocks virtually unbreakable. A hash function takes the information in each block and uses it to create the hashโa unique string of characters.
