Il "mining" è il processo del calcolo di spesa per proteggere i Bitcoin contro le inversioni e l’introduzione di nuovi Bitcoin nel sistema. Dal punto di vista tecnico, il "mining" è il calcolo dell’hash dell’intestazione del blocco, che comprende tra le altre cose un riferimento al blocco precedente, un hash di un set di transazioni e un "nonce" (un numero arbitrario utilizzato una sola volta per l’autenticazione).

In this article, we’ll walk you through all the latest buzz words and concepts in advanced blockchain development, but keep the details at a manageable level. What on earth are they talking about? We’re going to help you out.
In order to complete the verification faster than other miners, miners compete with each other using their computer hashing power. It is compared to the existing target, whether it is lower or equal to the current target. Miners test and discard millions of Nonce per second until they find that Golden Nonce which is valid. Once the Golden Nonce is found, btc they can complete the Block and add it to the Block Chain and there by receive the Block reward.
The digital, decentralized, deflationary asset (BTC) sold for $19,850.11 shortly after 10 AM EST, according to Coindesk data. It began trading that year below $1,000 but began smashing records in the summer, fueled by intense interest from retail investors, many of whom were taken in by a Ponzi scheme called BitConnect.

Pantera Capital, another investment firm dedicated to Bitcoin and its imitators, estimates that PayPal and Jack Dorsey’s Square (the owner of Cash App, a popular Bitcoin purchase on-ramp) are buying up BTC faster than it is being created, or "mined." Bitcoin
’s 2020 bull run has been fueled less by everyday investors and more by financial institutions, with firms such as Grayscale Bitcoin Trust leading the charge. In late October, PayPal (which also owns Venmo) announced it would begin integrating Bitcoin

As we’ve talked about, writing to the blockchain is slow and expensive. This is because every node in the entire network needs to verify and slurp in the whole blockchain and all the data it contains. Executing a large smart contract on a blockchain can be prohibitively expensive, and doing things like storing images on blockchains is economically infeasible.
