Blocks are linked together by cryptography – complex mathematics and computer science. Any attempt to alter data disrupts the cryptographic links between blocks, and can quickly be identified as fraudulent by computers in the network.
The next phase in the crypto mining process is to compile a list of all transactions, which is subsequently included in a new unconfirmed data block. It avoids “double spending” of any cryptocurrency and keeps a permanent and public record by adding their transaction to the blockchain, once the verification procedure is complete. The record is immutable, which means it can never be changed or corrupted.

Ricardo Salinas Pliego, a magnate with large operations in retail, banking and television who has been seen as President Andrés Manuel López Obrador’s closest business ally, wrote in his social media accounts Sunday that Bitcoin is a good investment.
A further blow was dealt when China ordered Bitcoin mining in its Sichuan province to shut down completely and furthermore told banks to stop supporting crypto transactions, in a latest wave of restrictions on cryptos.
