What are crypto-currencies, concretely?

It may seem trivial, but believe it or not, you are exactly defining a currency. Visit this site for cryptocurrency exchange.
Take the money from your bank account: what are other than entries in a database that can only be changed under specific conditions? You can even take coins and physical notes. What are they other than limited entries in a public physical database that can only be changed if you meet the requirement of physically owning coins and notes? Money is nothing more than a verified entry into a kind of database of accounts, balances and transactions.
How do miners create coins and confirm transactions?
Let’s look at the mechanism that governs crypto-currency databases. A cryptocurrency like Bitcoin consists of a peer-to-peer network. Each pair has a record of the complete history of all transactions and therefore the balance of each account.
An example for you
A transaction is a file that says “Bob gives X Bitcoins to Alice” and that is signed by Bob’s private key. It’s basic cryptography with public key, nothing special. Once signed, a transaction is broadcast over the network and sent from one peer to another. This is the basic peer-to-peer technology .Nothing special at all, again.
