Blythe Masters Unveils Fix for Blockchain Privacy Concerns

  • Firm details effort to keep trade data safe in white paper
  • Fingerprint data is only part of system shared among all users

Blockchain could finally drag Wall Street recordkeeping into the 21st century, but before they’ll use it financial firms want to know their data will be kept secret. The startup run by former JPMorgan Chase & Co. banker Blythe Masters says it’s found a solution.

The version of blockchain that powers the bitcoin currency is wildly transparent, recording each transfer of bitcoin from one person to another in a public database anyone can tap into. But such openness is anathema in finance, posing a conundrum for Wall Street firms otherwise drawn to digital ledgers because they could simplify and speed up recordkeeping.
