Implementation of mixer in golang

There are two major components

1. jobcoin-server: blockchain rpc server, that can generate new addresses, fund existing addresses, transfer funds between addresses and can check balance of a given address

2. mixer: mixer rpc server, that listens for mix requests from clients, returns a deposit address.

Mixer uses jobcoin rpc apis to poll jobcoin if funds to deposit addresses are transferred. If so moves funds to house address. payouts are made once there is good mix of users with similar payout amounts.

3. clients : jobcoin and mixer clients to interact with server apis

Running instructions

build jobcoin

$ cd go/src/panghalamit/jobcoin/jobcoin-server

$ go build .

test jobcoin

run go test -v inside jobcoin-server

run jobcoin

example:

$ ./jobcoin-server --port 3000 --txFee 1

build mixer

$ cd go/src/panghalamit/jobcoin/mixer

go build .

test mixer

make sure jobcoin is running on "0:3000" or pass appropriate address to function connectToJobcoin in TestMix

run go test -v inside mixer

run mixer

example:

$ ./mixer --mixerFee 1 --port 3001 --jobcoinAddr "0:3000"

Using clients

build clients

build jobcoin client

$ cd go/src/panghalamit/jobcoin/client/jobcoin

$ go build .

run jobcoin client

1. To query balance balance of an address

./jobcoin <jobcoinRPCAddr> <cmd> <addr>

example :

$ ./jobcoin "0:3000" 1 "qL3UDfyEcQAaUJ1lDSIZ"

2. To generate new address

./jobcoin <jobcoinRPCAddr> <cmd>

example:

$ ./jobcoin "0:3000" 2

3. To fund a existing address

./jobcoin <jobcoinRPCAddr> <cmd> <addr> <val>

example:

$ ./jobcoin "0:3000" 3 "KC4yYEwe5YJPuNAPeeMq" 1000

4. To transfer funds

./jobcoin <jobcoinRPCAddr <cmd> <from> <to> <val>

example:

$ ./jobcoin "0:3000" 4 "KC4yYEwe5YJPuNAPeeMq" "qL3UDfyEcQAaUJ1lDSIZ" 500

build mixer client

$ cd go/src/panghalamit/jobcoin/client/mixer

$ go build .

run mixer client

send mix request and get a deposit address. fresh addresses by client are put in a json file.

./mixer <mixerRpcAddr> <pathToFreshAddrJsonfile>

example

$ ./mixer "0:3000" fresh-addresses.json
