Ink Mainnet Snapshot

Snapshots are most often used during the setup of full nodes to accelerate the synchronization process. By bypassing the need to validate the entire blockchain from scratch, nodes can quickly catch up with the current state of the network. This approach greatly reduces setup time and improves overall efficiency.

In a standard blockchain synchronization, a node downloads and verifies every block and transaction sequentially from the network's genesis block. In contrast, a node snapshot enables much faster synchronization by allowing the node to download a pre-validated state of the blockchain at a specific block height, skipping the need to process all historical data.

The block number identifies the exact point in the blockchain's history that the snapshot represents. It defines the state and data captured in the snapshot, indicating up to which block the blockchain has been recorded.

The time required to restore a node from a snapshot depends on factors such as the snapshot's size and the performance of the underlying hardware. The process typically involves transferring the snapshot data to the node's storage and initializing the node from that state. For smaller snapshots, restoration may take only a few minutes, while larger snapshots or slower network and storage systems can extend the process to several hours.

In most cases, snapshots are specific to a particular blockchain client or node implementation because they depend on how the client stores and structures data. Using a snapshot from one implementation with another may result in incompatibility or data corruption. Always verify that the snapshot you are using is designed for the same node software and version to ensure a successful restoration.

The frequency of snapshot creation varies depending on the blockchain network and its maintenance policies. Some networks generate snapshots automatically at regular intervals, such as daily or weekly, to provide up-to-date starting points for new nodes. Others may only publish snapshots manually or during major updates. Regularly updated snapshots help ensure faster synchronization and minimize the time needed to catch up to the current chain state.
