A snapshot refers to a specific moment in time when the state of a blockchain is recorded. This is often used to capture the balances and data of users at that point, providing a clear reference for various purposes.Snapshots are frequently utilized during events like token airdrops, forks, or changes in governance. For example, if a new token is being distributed, a snapshot can determine who is eligible based on their holdings at that instant. This ensures that only those who held a certain cryptocurrency by the snapshot date receive the new tokens.In addition, snapshots can serve as a backup method to recover lost data or allow the analysis of historical data trends. By referencing a past state of the blockchain, developers and analysts can examine changes over time or troubleshoot issues in the network.Overall, snapshots are essential for managing participation in new projects and help maintain the integrity of transactions and user balances within the system.
