hyperledger composer essential acls  If you don't know how to setup hyperledger composer read this post . I almost gave 5 days 😅  to add an asset via participants other than Admin. As I get an error about some permission for that kind of participant I was adding that resource permission to that participants ACL. .. .. And I have almost given 8 system permissions including network and asset registry resources. Actually, I don't find a solution on any blog or documentation, but  (guess what? 😳) I found a solution on someone's GitHub sample project. That I am sharing here.

Go supports built-in server. But there is a limitation that you can host only one site at once with one port. Though you can host multiple sites with the domain name using gorilla mux then all site will come with one app that will be very hard to maintain and update.  Another option is you can host your site with different ports and then use the reverse proxy to map to map the domain name to the port Explanation Scenario  I have two sites running on my vultr vps . All of them are website that means request will be come in with  domain name and going to be arrived on the port 80 . If  I assing one program [ site ] to listen to the port 80 others will not be able to listen on port 80.  Condition Requirement is that requests should be listend on port 80 and handled by the app to which it relates. After struggling for 3 days i got this 😂 silly solution. Source Code ( solution I got ) 1 2 3 4 5 6 7 8 9 10 11 1...

There is no direct best ( or at least I don’t know ) way to create a good development environment for the hyper ledger composer on windows. I have installed hyper ledger on windows and it’s also not working satisfactorily. I want to develop in windows while want to run it smoothly like in Ubuntu. So the way I found is virtual box and ssh. Vagrant is kind of the thing that gives this readymade. But .box file we need to download is very slow in speed [ 150 kbps] and for me, it was disconnecting continuously. So I left the vagrant and find another way to get the facility provided by the vagrant. I am going to show the way I created my development environment. You Need  Virtual Box ISO of ubuntu server 16.04 LTS OR Ubuntu Virtual Box  Machine That's it. If you have this two things you are ready to go. Prepare Ubuntu Server Virtual Box Machine Either install ubuntu 16.04 on the virtual box or import the ub...
