Access control

[3Mohammed2013]

I would like to implement the access control list on the Ethereum Blockchain it self could that wil be possible because you suggested me to implement through proxy serve but I need like stamp will be appear in the ethereumj it self so

Sorry, but I hardly understand what do you want to make. An ACL for smart contract?

[3Mohammed2013]

I want to implement the access list rather than smart contract or with smart contract so that everyone in the blockchain his own key and should be unique key and if some one want access our Blockchain he should know the key
The key shall compatible within the Blockchain itself

[mkalinin]

I see. So, you want to have a private blockchain that is closed for arbitrary users. For entirely closed blockchain (nobody could even read from that) you'd better think toward some private intranet + proof of authority consensus. You may read more about PoA consensus implementations in go-ethereum and parity

[3Mohammed2013]

But how this work with Ethereum Harmony

[mkalinin]

Harmony does not support PoA consensus protocol yet. We have an implementation of it in our plans. But you may fork EthereumJ, implement your own PoA algorithm in it (basing on ideas put in PoA implementations of go-ethereum and parity) and then use your own EthJ with Harmony.
