importBlocks(from:)

Imports blocks from on-disk block files (blk00000.dat-style).

@discardableResult func importBlocks(from filePaths: [String]) -> Bool

Parameters

filePaths: Absolute paths to block files. Empty list is a no-op that returns true.

Return Value

true if import completed successfully (or there was nothing to do); false if any file failed to import.

Discussion

Replays raw block files into the chainstate — typically used after copying a block directory from another node to avoid re-downloading historical blocks. This is a long-running operation; cancel via interrupt().
