## Block Confirmation
Block confirmation is the process of verifying blocks on a blockchain. It involves using cryptographic algorithms to verify the validity of newly discovered blocks and confirming that they are valid parts of the chain. The purpose of block confirmation is to ensure that all users have access to an up-to-date and secure ledger, as well as preventing malicious actors from manipulating the blockchain.
In order for a new block to be confirmed, it must pass certain tests within its network in order for it to be accepted by other nodes as part of the chain. To do this, miners use specialized software known as mining rigs which contain powerful computers dedicated solely to discovering and verifying new blocks within the blockchain. After locating a new block, miners must then solve complex mathematical puzzles before submitting their solutions back into the network for verification. If enough miners confirm that these solutions are correct, then it becomes part of a newly added “block” linked onto an existing chain – thus creating what’s known as a “confirmation”.
When this happens, transactions associated with that particular block become validated and can now be considered part of history inscribed on said chain permanently; meaning no one can tamper or alter them without detection or being detected by other participants in said network (e.g., nodes).
The number of confirmations required may vary depending on how much trust there needs to be placed in each transaction; typically ranging anywhere from 1–3 confirms at lower levels all way up 10+ confirms if higher security requirements are needed – such those related banking systems or highly sensitive data transfers/transactions between two parties involved (i.e., two banks).
It is important for users looking into cryptocurrencies understand how important block confirmation is in maintaining security across networks and ensuring transparency when making transactions over public ledgers like Bitcoin’s blockchain technology today – where anyone has access view details about any given transaction recorded onto said ledger publicly online anytime they want!
