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 &
Is there something that I have missed out?
Is it possible to have somehow similar user accounts in Besu like Fabric?
ANSWERAnswered 2021-Dec-16 at 09:31
After my own research I have concluded that these are the only ways to create accounts for Hyperledger Besu:
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

This should be fixed in v0.0.26
The github issue you posted has been updated https://github.com/ConsenSys/quorum-dev-quickstart/issues/81. Could you verify please and let us know if this is still an issue
I'm using Web3.py, and a permissioned Hyperledger Besu network.
When trying to use w3.eth.contract(...) method to deploy a smart contract into the network, I get the following error:...

You are likely to use Infura node or similar.
I'm running a Hyperledger Besu private chain and making a sendSignedTransaction call from an Express server....
ANSWERAnswered 2021-May-19 at 22:08
You can decode the
revertReason using web3.utils.hexToAscii().
I have a call to estimateGas from an Express server to a private Hyperledger Besu chain and everything was working fine yesterday, yet today when I run the same method it's returning "Error: Returned error: Internal error". Nothing changed in the code between yesterday and today, and I'm lost as to where to even start troubleshooting.
That is the extent of the error, nothing more descriptive is given, and after googling for hours, I haven't found anything that could help. The stack trace points to the error handler file in the web3 node module.
Code (actual methods and parameters omitted for security reasons):...
ANSWERAnswered 2021-May-18 at 21:30
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 :...
ANSWERAnswered 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.
you can find more details here

ANSWERAnswered 2020-Nov-19 at 03:45
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 want to get started with Hyperledger Besu, after following the steps of the official documentation here and running the following command:

ANSWERAnswered 2020-Feb-22 at 15:22
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.
No vulnerabilities reported
You can use besu like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the besu component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
