.startMining( oOptions, pfnCallback )

start mining

• oOptions

name	type	optional	comment
.bufInputHeader	Buffer	no	140 bytes Buffer object
.difficulty	Number	no	number
.calcTimes	Number	yes	default value : 30, compute times per loop
.maxLoop	Number	yes	default value : 10000000, max loop

• pfnCallback( err, oSolution )

oSolution is a plain object :

{ win : true, hashHex : sActualHashHex, nonce : uActualNonce }
{ win : false, gameOver : true, hashHex : null, nonce : 0 }

const _miner	= require( 'trustnote-pow-miner' );

        bufInputHeader	: bufInput,
        difficulty	: nDifficulty,
        calcTimes	: 30,
        maxLoop		: 1000000,
    };
