Integrate Connext 2.0 into `videoDAC` template pay-to-play stream Consumer app #21

Open criticaltv opened 4 years ago

criticaltv commented 4 years ago

Current Situation

Currently, Video DAC's pay-as-you-go Android app template (e.g. used in Görli TV app) can be configured to make payment of 0.0005 ETH (~13¢) via the app every 1 minute using native onchain ETH transactions.

Each transaction requires gas to be paid (21,000 units), which at 2 gwei gas is 0.000042 ETH (~1.1¢), or 8.4% fees.

This is relatively expensive, when charging e.g. 10¢ per minute, and it hinders us from charging per second (instead of per minute).

Scope of this issue

This issue is about integrating the Görli TV app with Connext 2.0, to allow payments to be made with lower (preferably zero) per-payment transaction costs.

The app should release payment into the recipient's control after every 1s of streaming video content watched by the viewer.

Out of scope

The app does not need to:

Implications of this functionality

The key output of this functionality would be to allow the app to be configured to send smaller payments per unit of time. For example, sending

0.0001 $DAI per 1 second of video played. This equates to e.g. 0.6¢ per minute, or $0.36 per hour of video played.

It would also enable payments in ETH or an ERC-20 token (e.g. a Stablecoin such as $DAI, or a project's own coin such as $BAT, $MKR, $OMG, $SNT, $OXT, $ZRX, $PLN, $JULIEN, $cDAI, Tether).

I am kind of unsure how connext will work, as they have only js SDK and I couldn't find RPC endpoint for their testnet either.

criticaltv commented 4 years ago

@Abhimanyu121 take a look at the J2V8 lib https://github.com/eclipsesource/J2V8 to integrate the connext npm package with Kotlin's Java bindings.

It runs the V8 javascript engine so it could be very performant.

Ok will pause working on this for now, so that I research on better ways of doing the connext integration without the server side dependencies.

criticaltv commented 4 years ago

@mul1sh this makes sense. Thank you for the update.

Maybe there could be a very elegant solution in conjunction with the "work in progress" being done by @psudoanon on the MVP "Livestream-to-earn" Publisher Template App?

In that case, the Publisher device will be guaranteed to be "online" to "receive payment" because it's publishing the livestream.

If @mul1sh has done the work on the "Consumer" side to send micro-payments using Connext 2.0, then perhaps it might just be a case of doing the work on the "Publisher" side to receive them?

Thoughts?

mul1sh commented 4 years ago

@criticaltv yes correct so long as the pulisher can create a connext channel and we also have a way of querying the channels public id, then its very much possible to do the micro-payments.

criticaltv commented 4 years ago

OK, so, let let @psudoanon finish up https://github.com/videoDAC/android/issues/31 and then look at a new piece of work to connect the Publisher App with the Consumer App.
