How the blockchain will become our new signatureWhen a baby boy was born on August 4, 1961, the local newspaper announced his birth, as it did many others. More than a declaration of happy news by his parents, those few lines of information were part of a long-lasting tradition -- using the local daily to register, at a set point in time, the addition of a new person to society. Seemingly inconsequential timestamps like these occur every day and, as it turns out, play a key role in ensuring more fair and just societies.
