Mini blockchain implementation in Elixir
This development is inspired on Haseeb Qureshi Ruby's implementation:
Considering you are in the root directory of the repo, then
$ docker build -t <IMAGE NAME> .
Finally, create the network the future nodes will share, let's name it blexnet
$ docker network create blexnet
To start the network (genesis node), just start the first container, i.e.
$ docker run --name node --network blexnet <IMAGE NAME>
And then, to join consecutive nodes to the network, a peer ip address needs to be specified, i.e.
$ docker run --name node2 --network blexnet -e PEER=172.18.0.2 <IMAGE NAME>
$ docker run --name node3 --network blexnet -e PEER=172.18.0.3 <IMAGE NAME>
$ docker run --name node4 --network blexnet -e PEER=172.18.0.2 <IMAGE NAME>
PEER can be any peer ip address already existing in the network.
Even though any http client can be used to make post requests to the api in order to submit transactions, there is a mix task available for that as well (easier, right?). All three arguments must be specified, i.e.
$ docker exec node3 mix blexchain.transfer from:172.18.0.2 to:172.18.0.3 amount:100
from and to are the peer ip addresses whose nodes are running on.
node3 can actually be any node in the network
To run the test suite locally, do so via mix test
