MOAC Pizza Alpha (Pangu 0.8.3 prerelease)

--Debian/Ubuntu/CentOS-- This version only work with "--dev" option, not working with mainnet or testnet yet.

There are two tar files: pizzaAlpha.vnode.ubuntu.tar.gz. - vnode executables and files; pizzaAlpha.scs.ubuntu.tar.gz - three scs executables and files.

Untar the file using tar, there are 4 directories:
```
 vnode
 scs1
 scs2
 scs3
```
Start the vnode $ ./start_vnode.sh
from another terminal, run moac again to attach the running node
```
 $ ./attach.sh
```
Check and create coinbase account
```
 >personal.newAccount()
```
from console prompt, start mining by running
```
 >miner.start(1)
```

After vnode started, start scs servers. You need at least 2 scs servers to form the microchain.
from another terminal, change into scs1/bin run the executable
```
 $./scs1
```
do the same for the other two, if connected with vnode, some info should be seen as the following:
```
 ......
 INFO [05-23|01:21:56.111] 230:liveinfo: {1285} 
 INFO [05-23|01:22:00.111] 221:liveinfo: {1286} 
 INFO [05-23|01:22:05.112] 205:liveinfo: {1289} 
 INFO [05-23|01:22:08.111] 206:liveinfo: {1290} 
 INFO [05-23|01:22:09.120] 222:liveinfo: {1291} 
```
The number in {} is the vnode block number. All 3 scs should have the same info.

scs servers need some initial funds to work. Currently there are fixed address for the test scs servers:

 scs1="0x027aee503f2e27fee5103df1796daeb6111e204d"
 scs2="0xba3597b4c20f0477c4ebe7cf81c565e556bd52f9"
 scs3="0x1675124b338671dd771a673c7d06606ae1cdd7b0"

Otherwise you need to send some funds to the accounts. From prompt, load script

 >loadScript("mctest.js")
 >Send(mc.accounts[0], '', scs1, 0.1)
 >Send(mc.accounts[0], '', scs2, 0.1)
 >Send(mc.accounts[0], '', scs3, 0.1)

Now start deploy the microchain from vnode:

 deploy_p1.js: protocol needed for microchain.
 deploy_s1.js: microchain contract.
 test_s1.js: test scripts for microchain.

    > personal.unlockAccount(mc.accounts[0])
    true
    > loadScript("deploy_p1.js")
    null [object Object]

Testnet deploy:

    Contract mined! address: 0xeaf8f52588af16aebb26c4ca8fb10d5e0b8b1d70 transactionHash: 0xf029d6168c289fac8322bb1925205c905f31a4cc45dc826f4e3b7200ceda3de5

Load the subchain script file:

 > loadScript("deploy_s1.js")
 null [object Object]
 true
 Contract mined! address: 0x78934339dcb0642bdfd2afb3e028ee40be809280 transactionHash: 0x503fb3377866071a80e4f023c2cab4999876b93fbaa86dec54d73b1d4d8391a7

Load the test script.

 > loadScript("test_s1.js")
         true

 > registertopool(scs1)

 undefined

You can see if the node is registered:

 > subchainprotocolbase.scsCount()
     2

For safety issues, scs servers need to wait for some blocks after register in the pool. You can find the info about a scs server by:

 > subchainprotocolbase.scsList(scs1)
 ["0xecd1e094ee13d0b47b72f5c940c17bd0c7630326", 12000000000000000000, 942, 1.15792089237316195423570985008687907853269984665640564039457584007913129639935e+77]

The number '942' is the block number this scs server can join microchain, usually this is 50 blocks later after the scs registered in the pool.

Open subchain for scs to join:
When there are more than 2 scs in the pool, you can start open the microchain for scs server to join You may need to unlock the mc.accounts[0] for this step.
```
 > personal.unlockAccount(mc.accounts[0])
 true
 > registeropen()
 miner.starsending from:0xa8863fc8ce3816411378685223c03daae9770ebb to:0x26c27eb5585d1e978d4da14f0eb2ee479d733a46 amount:0 with data:0x5defc56c
 undefined
```
There will be some confirmation tx send from vnode to scs servers. You can also check to see how many scs servers are selected in the microchain:
```
 > subchainbase.nodeCount()
 2
```
When you have enough scs servers, you can close registration and start the microchain:
```
 > registerclose()
 sending from:0xa8863fc8ce3816411378685223c03daae9770ebb to:0xc3c6e85820d97477172498ce7aed37b0bb22e67e amount:0 with data:0x69f3576f
```

Subchain mining started: After these steps, scs server should have some info like:
