A Chain Snapshot refers to a point-in-time record of a blockchain’s state. It captures essential data, including account balances, transaction histories, and smart contract statuses at a specific moment. This allows users to understand the entire network’s status without analyzing the entire transaction history.Snapshots are often useful for various purposes. For example, they can facilitate airdrops, where tokens are distributed to holders based on the snapshot taken. This ensures that only valid participants receive rewards based on their holdings at that precise time.Another key use is during network upgrades or forks. A snapshot can serve as a historical reference point, allowing participants to track changes and balances before and after significant alterations in the network.Overall, a Chain Snapshot provides a practical way to record and reference blockchain data, ensuring transparency and facilitating various operations within the ecosystem.
