HOW TO ADJUST THIRD-PART POOL SOFTWARE TO Neoxa

The theory

Neoxa has a feature of remaining 10% of coins for community develpoment according to the Whitepaper, to implement this, Neoxa add 2 additional value when submit new block to the main network:

"CommunityAutonomousAddress": "HCAo9dVTEo8EE1UASQ9cSW1DuU5aDo39Ph",
"CommunityAutonomousValue": 50000000000,

These 2 values are in the RPC data when the pool request block template, and when the pool generate a new block and add it to the chain, the request data also must contain these 2 values:

strCommunityAutonomousAddressHash
CommunityAutonomousValue

When the blockchain receive a new block it will check those 2 values, note that "strCommunityAutonomousAddressHash" is Base58 of "CommunityAutonomousAddress", if the values are missing or wrong then the network will reject new block request, therefor if any third-part pool wants to implement Neoxa must do some tweak with their rpc data.

For NOMP based systems

Many pools are NOMP based systems, NOMP is a nodejs based system witch has separate stratum protocol as a different project, you simply need to replace stratum lib in dependency, located in packages.json

"dependencies": {
    "stratum-pool": "git+https://github.com/tweetyf/kawpow-stratum-pool.git",
}

This project already has implementation of the values in protocol.

For other pool systems

We haven't try other systems, but due to json-rpc can be implement in any program language, you only need follow the block template.

The main modification in nodejs project https://github.com/tweetyf/kawpow-stratum-pool/blob/master/lib/transactions.js line 90:

//strCommunityAutonomousAddress 10% of coinbase
var strCommunityAutonomousAddress           = rpcData.CommunityAutonomousAddress;
var strCommunityAutonomousAddressHash       = bitcoin.address.fromBase58Check(strCommunityAutonomousAddress).hash;
tx.addOutput(
    scriptCompile(strCommunityAutonomousAddressHash),
    Math.floor(rpcData.CommunityAutonomousValue)
);

Other platform can use the code as reference.
