Sept 3 (Reuters) - Brazil's Vale conducted its
first iron ore sale via blockchain to a subsidiary in China of
Nanjing Iron & Steel in what the mining company said
was an important milestone towards digitalization of sales.
The letter of credit was issued through Contour's blockchain
platform in a procedure that significantly reduced the
quantity of e-mails and paperwork, the mining company said.
