Usage

1. Run MyDexChain:

MyDexChain docker file is stored in dockerhub and ready for use with command: (Please check the version and use as tag rather than latest)

docker run -d --rm -p 2020:2020 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

After docker container comes up run the command;

docker ps

Output: db641c6c55b7 mydexchain/mydexchain "/startup.sh" 32 seconds ago Up 31 seconds 0.0.0.0:2020->2020/tcp, 5432/tcp mydexchain

2. Follow Blocks:

docker attach mydexchain

FAQ

How Can I Calc Fee

Where Can I Run MyDexChain Node?

You can run MyDexChain Node on

• Amazon Web Services
• Azure
• Google Cloud
• Your Own Server/Desktop

How Can I Update to the Latest MyDexChain Version?

Run the command on Current DockerHost:

docker kill mydexchain && docker pull mydexchain/mydexchain && docker run -d --rm -p 2020:2020 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

Common Problems

These options are settings that change shell behavior. The following table is a list of options that might be useful to you:

Check	How
Cannot connect to the Docker daemon. Is the docker daemon running on this host?	Check your docker service is up and running.
Block Sync is not working	Check your internet connectivity.

How to Backup the MyDexChain Node?

MyDexCahin maps blocks inside PostgreSQL and it has been addressed inside dockerfile. All the data is saved inside /var/lib/docker/volumes/mydexchain and make sure that you backup the folder.

Sample Fee Calculation

Transaction Amount	Fee %	Fee Amount
1000	0.003	3.00
10000	0.0003	+2.70
100000	0.00003	+2.70
1000000	0.000003	+2.70
10000000	0.0000003	+2.70
100000000	0.00000003	+2.70
1000000000	0.000000003	+2.70
10000000000	0.0000000003	+2.70
100000000000	0.00000000003	+2.70
		24.60

25000 myDexChain Transaction = (1000 x 0.003) + (9000 x 0.0003) + (15000 x 0.00003) = 6.150 Fee
