Traditional money relies on a gold cover kept in central banks, so that each banknote reflects a proportion of this gold. The value of decentralized digital currencies is their encryption, which is based on a technology called blockchain.
Blockchain is a network of computers connected to the same renewed cash register in real time. This record is renewed by the calculations of digital money, who bought, who sold and what price is current based on supply and demand, and this account is also renewed in new manufactured currencies.
Cryptocurrency manufacturing is known as mining, a complex encryption process that requires powerful specialized computers, consumes a lot of electricity, and takes long periods to manufacture a single, original, hard-to-penetrate or imitation currency.
If a hacker succeeds in imitating a currency, or hacking a computer to steal digital currencies, the rest of the blockchain-related devices detect this breach, identify the source of these coins or their original owner, if any, and correct the record. This is the principle on which the NFTs depend, now there can be an original digital entity, which cannot be copied and pasted.
