# recblock
Blockchain for a record management and money transfer system
## Build package native
```zsh
$ zig build
```
## Build for windows on linux
```zsh
$ zig build -Dtarget=-Dtarget=x86_64-windows-gnu
```
## Build for linux static
```zsh
$ zig build -Dtarget=x86_64-linux-musl
```
## Build in release mode
```zsh
$ zig build -Drelease-fast
```
## HOW TO USE PROGRAM
### create a wallet
```zsh
$ zig build run -- createwallet
#.eg. to create two new wallets
# Assan's wallet
$ zig-dev build run -- createwallet
Your new address is 'AY0IZ21T7XFFEPwoiVxAbnYMxuZNshdRzg'
# Gaddy's wallet
$ zig-dev build run -- createwallet
Your new address is 'AZqc8JTbSu1xMQQD2TcVRZnj5oji5oIOLQ'
```
### create a chain
```zsh
# 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
```zsh
$ 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
```zsh
$ 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
```
### print the blockchain ledger after performing some transactions
```zsh
$ zig build run -- printchain
# eg
$ zig build run -- printchain
