The government's standard-setting body BIS on Tuesday said it is framing standards for emerging technologies like blockchain, and asserted that it will not extend April 1 deadline for making six-digit alphanumeric HUID mandatory for gold hallmarked jewellery. Addressing a press conference, Bureau of Indian Standards (BIS) Chief Pramod Kumar Tiwari said, "We make standards in order to promote ease of doing business. Our national standards are being harmonised with the international standards so that our external trade is smooth".
