I build a permissioned network using Quorum,

I have a peerA which has a private smart contract, another peerB that cannot invoke functions of the smart contract as it is private

So, can peerB send transaction to peerA to request it to invoke a function from his private contract.

Not through a txn on the chain. If a private contract is defined between party A and B, and C needs to execute a call then this would have to be handled with an off chain call in some way, for example through an API offered by A or B.

  • Can I define another contract X for the peer A that is not private and that contains a function that calls the function in his private contract Y? Then, B can invoke the function in contract X in order to invoke the function in contract Y. It that possible and what could be the pros and the cons of such solution ? – A.Gh Jan 17 at 10:38
  • Hi, at the moment, the state model only permits reading from public contracts in a private contract. Public contracts cannot access contents of the private state at all. – fixanoid Jan 18 at 3:13
  • Hi fixanoid, many thx for your help, just I want to be sure about one thing. This is even if the private and the public contract are deployed by the same node? In fact here github.com/jpmorganchase/quorum/issues/357 I found that it is possible: "On node 1 i can properly add SimpleStorage-contract to StorageContainer and also i can get private value 45 from it. On node 7 or 4 i get value 0. So all works properly." – A.Gh Jan 18 at 11:10
