Blockchain could soon power stock markets, music sales, and even prevent child l-1 (technology,different,activists,something,currency)
.
   It's a technology conceived by the mysterious creator ofbitcoin— the digital currency championed by a motley crew of privacy-obsessed libertarians, social activists, and some criminals.

  Now the idea of blockchain has gripped Wall Street's biggest institutions.
   Its enthusiasts think it could change the world. Sure, it would make contracts more enforceable and speed up the settlement of stock trades — hence the interest from big banks. But some see it going much further, cracking down on sex trafficking , music piracy, and child labor.
  And the key to all that — what attracts these different factions — is something that, on the surface at least, sounds rather banal: a digital ledger, like the one in your checkbook.
  "Blockchain is a truly extraordinary technology that does really mundane things," said Paul Brody, Ernst & Young's global blockchain leader.
  But for all the promise, these big questions remain: Who will foot the bill, and is it really as secure as supporters say?
  What is blockchain?

  In the non-blockchain world, we keep separate records of transactions. If you write your friend a check, you balance your own checkbook and your friend does the same when they deposit it. But things can go wrong. They might forget to update their checkbook ledger. And each bank has no way to know immediately if the person has enough in their bank account to cover it.
