            Hyperledger Besu - User Account Management
            Asked 2021-Dec-16 at 09:31

            I have recently started to learn the Hyperledger Besu, and what I am trying to do is actually compare Besu with Fabric and see if it is compatible with my already finished Fabric project.

            I know from Fabric that using the CA from an organization we can create new users that are under that org. Also, there is the option to name this user with a username and add some custom attributes that can be used in the chaincode like attribute role for example.

            Now, in Besu I have only discovered so far that only with some third party tools like MetaMask and the js library web3j we can create accounts. Although, those accounts are in the form of Public Key/Address & Private Key.

            Is there something that I have missed out?
            Is it possible to have somehow similar user accounts in Besu like Fabric?

            Thank you

            After my own research I have concluded that these are the only ways to create accounts for Hyperledger Besu: MetaMask Wallet

            web3 js library through javascript

            In order to have more specific accounts that may be connected with some user information or roles that could determine various things in the application, the most suitable option is the following:

            Use a centralized database to store the user information and associate it with the users address. This database could be used from a client application where the user can login with his/her credentials or using a third-party wallet like MetaMask.

            Also, to distinguish the users inside the smart contracts the best option so far seems to be the library of OpenZeppelin Ownable

            It can be a problem on your web3 provider, but more likely option is that executing of the myMethod() would result in reverting the transaction - that's why it probably throws the error.

            You can encapsulate the method in a try/catch block to catch the error message.

            I am using the quickstart network provided by Hyperledger besu, and I want to test and see how permissioning works with the permissioning management dapp. I use this repo: https://github.com/bretthenderson/besu-quickstart So when I run the run-permissioning.sh script to build the dapp and run the test network everything works fine and the network starts succesfully then when I run the run-permissioning-dapp.sh script it works fine and it compiles and deploys the permissioning smart contracts then restarts the network with permissioning enabled but after that the bootnode container crashes with these logs :

            ANSWER

            Answered 2021-Apr-02 at 12:16

            The fix is to the issue is to add --permissions-nodes-contract-version=2 to your besu command line.

            This is because in v 2.0.0 of permissioning smart contracts repo we changed the interface as per the changelog https://github.com/ConsenSys/permissioning-smart-contracts/releases/tag/v2.0.0 It is in the besu docs here https://besu.hyperledger.org/en/stable/HowTo/Limit-Access/Specify-Perm-Version/ but I have already reported this issue and it has been fixed on the documentation of on-chain permissioning tutorial.

            The error means that you have an existing database for another network, probably medalla.

            Try starting your beacon node with the flag --clear-db next time, and you'll see it the error disappear and start syncing Pyrmont.

            I have no prior experience with the library which is in discussion, but I have just had a look at the official docs of the library which you are trying to use, and the installation instructions state that you require Java 11+ to complie

            Hyperledger Besu requires:

            MacOS High Sierra 10.13 or later versions

            Java 11+ to compile; earlier versions are not supported.

            From your question, it looks like your system is running Java8. Trying bumping it up to java 11 and try starting the binary again.
