Motoko Base Library: Blob

Blobs represent sequences of bytes. They are immutable, iterable, but not indexable and can be empty. Byte sequences are also often represented as [Nat8], i.e. an array of bytes, but this representation is currently much less compact than Blob, taking 4 physical bytes to represent each logical byte in the sequence. In this video, we cover what blob is and their practical manipulation.
