A Fresh Block refers to a newly created block in a blockchain that has just been added to the chain. This block contains a collection of transactions that have been validated and included by miners or validators.When a miner successfully solves a complex mathematical problem, they create a Fresh Block. This block is then broadcasted to the network, where other participants verify its legitimacy. Once confirmed, the Fresh Block becomes part of the existing blockchain, ensuring that all transactions are recorded securely and accurately.The creation of Fresh Blocks is essential for maintaining the integrity and security of the blockchain. Each block is linked to the previous one, forming a chain. The more Fresh Blocks that are added, the more secure the entire network becomes against tampering or fraud, as altering any block would require recalculating all subsequent blocks.In summary, a Fresh Block represents a moment of progress in maintaining a decentralized and secure ledger of transactions within a blockchain system.
