What Is a Snapshot?
In the blockchain context, a snapshot refers to capturing the state of a blockchain at a specific block height.
It is a record of token holders’ overall quantity and balance at a particular moment.
The Traditional Interpretation
Outside of the blockchain world, a snapshot is similar to photographing data on a server or storage device at a specific time.
It captures the metadata that represents the state of the information rather than duplicating the entire data.
These snapshots are often used in test and development environments to create clones of data for testing new applications or settings without affecting the live system.
Snapshots also serve as a fast failsafe, allowing you to roll back the server to a previous state if an error occurs.
Cryptographic Snapshots
In the context of cryptocurrencies, a snapshot refers to recording the status of a blockchain at a particular block height.
It captures the entire blockchain ledger, including all addresses and associated data.
Snapshots in Crypto Airdrop Events
Snapshots are commonly taken before each round of a crypto airdrop event.
During the snapshot period, the balances of blockchain addresses are recorded, and tokens are subsequently distributed based on those balances.
Users can usually move their funds after the snapshot without affecting their eligibility for the airdrop round.
