Is it possible to use "Flash channels" to send non-transactional data, A.K.A 'zero-value' transaction type which simply broadcasts a message or data?

If so, is it free? And how to do it?

  • Why would you want to do this? Why not simply broadcast a message or data without Flash Channels? – Zauz Jun 25 '18 at 10:56
  • because it is faster – user3785971 Jun 25 '18 at 11:00
  • No, it's not... Where did you get the impression, that it would be? – Zauz Jun 25 '18 at 11:03

  • They enable the transacting of Iotas without doing Proof Of Work (doing POW takes a long time). But for sending data over the Internet (or any network), you don't have to do POW. You just send the data. – Zauz Jun 25 '18 at 11:16

Transactions made in flash channels are not written to the Tangle.

There are only two events that are stored:

  • opening of a flash channel
  • closing of a flash channel

When opening a flash channel, two (or more) entities, let's call them Alice and Bob, lock up Iotas.


This is why it wouldn't make sense to "broadcast a message or data" via Flash Channels. It would be just as good as broadcasting it without flash channels.

  • Is it possible to store the data that flows from one address to another into a private blockchain/DAG since it is not being stored on the Tangle ? – user3785971 Jun 26 '18 at 17:33
  • Of course, it's just data. You can do anything you want with it. But you would have to pay fees/do POW (whatever the private blockchain/DAG requires you to do in order to store data). – Zauz Jun 26 '18 at 17:37
