Your new address is 'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ'

create a chain

# create a blockchain at Gaddy's wallet
$ zig-dev build run -- createchain AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ

#.eg output
$ zig-dev build run -- createchain AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ
info: new blockchain is create with address 'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ'
hash of the created blockchain is '0031D180D286BD75D0BD543AD391E071A36A32157C2D11D9629B9B7EA5B5349C'
info: You get a reward of RBC 10 for mining the coinbase transaction

get balance

$ zig-dev build run -- getbalance AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ

# get Gaddy's balance
$ zig-dev build run -- getbalance AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ
'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ' has a balance of RBC 10

# get Assan's balance
$ zig-dev build run -- getbalance AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg
'AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg' has a balance of RBC 0

send RBC to another Address

$ zig-dev build run -- send --amount 7 --from AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ --to AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg

# send RBC 7 from Gaddy's wallet to Assan's wallet
$ zig-dev build run -- send --amount 7 --from AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ --to AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg
info: new transaction is '000AFBA4B03A90EDDF3B4534176714E39981F86AD8CAF5C773D48DE520F164B8'
done sending RBC 7 from 'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ' to 'AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg'
'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ' now has a balance of 3 and 'AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg' a balance of 7
