word issue in https://docs.iden3.io/publications/pdfs/Merkle-Tree.pdf

There seems to be a word issue in https://docs.iden3.io/publications/pdfs/Merkle-Tree.pdf.
In section '2 Motivation', should 'has' in the sentence 'Merkle trees allow to link a set of data to a unique has value' be changed to 'hash'?
