Support or not #1212

Closed 3Mohammed2013 closed 5 years ago

Dear Developer, I have a couple of the question. if you do not mind

1- EthereumJ and Ethereum Harmony run in which protocol Proof of work POW, POS 2- Is EthereumJ and Ethereum Harmony support the Proof of authority POA? or not yet if yes, please share with me document approval or steps to find these things.

1 - We support PoW, default ethereum proto, we don't support PoS. We have tree with Casper implementation but there were decided to drop Casper in favor of shasper (sharding + casper), so we are moving this way in https://github.com/ethereum/ethereumj/tree/research/sharding . But it will definitely took some time until we have anything usable. Months. 2 - We don't support PoA. While we are thinking about it from time to time, we have no schedule for it. If anyone is interested in adding PoA support, we are open to review code and help. But we don't have resources to implement it by ourselves in the coming months.

Dear Dmitry, is there are any possibility to integrate your application ( Ethereum Harmony & Ethereumj ) with IoT devices AND as you know POW is consuming high power consumption, is there any way to integrate with each other?

zilm13 commented 5 years ago

@3Mohammed2013 I think no way pow could work on IoT. Too heavy. You are right. Both PoS and PoA could be usable for light clients. So you could either wait for some shasper implementation, including light clients support or take some existing client (not EthereumJ) supporting PoA.

@3Mohammed2013 btw regarding to the shasper, take a look at https://github.com/status-im/nimbus shasper is in R&D stage and everything is not done yet and changing, but you can follow updates, these folks are focused on shasper implementation on devices with limited resources.
