What does bitcoin look like?
Bitcoin, as such, does not exist. You can not show on any physical object, file or lines of code and say: "This is Bitcoin." When we say that “I have 1 Bitcoin,” in fact, our address does not store digital coins in the form in which, for example, dollars or rubles are stored in bank accounts.
The presence of bitcoins in our country is indicated only by records of transactions between different addresses. Every transaction ever conducted is stored on the blockchain. And the balance of the wallet is the calculation of all transactions carried out by you or at your address. In the blockchain, terms such as Input are used for this — a record of what address the bitcoins were obtained from; and Output - to which address the bitcoins were sent.
