示例1: GetGeometricMeanPrevWork
arith_uint256 GetGeometricMeanPrevWork(const CBlockIndex& block)
{
//arith_uint256 bnRes;
arith_uint256 nBlockWork = GetBlockProofBase(block);
CBigNum bnBlockWork = CBigNum(ArithToUint256(nBlockWork));
int nAlgo = block.GetAlgo();
for (int algo = 0; algo < NUM_ALGOS; algo++)
{
if (algo != nAlgo)
{
arith_uint256 nBlockWorkAlt = GetPrevWorkForAlgoWithDecayV3(block, algo);
CBigNum bnBlockWorkAlt = CBigNum(ArithToUint256(nBlockWorkAlt));
if (bnBlockWorkAlt != 0)
bnBlockWork *= bnBlockWorkAlt;
}
}
// Compute the geometric mean
CBigNum bnRes = bnBlockWork.nthRoot(NUM_ALGOS);
// Scale to roughly match the old work calculation
bnRes <<= 8;
//return bnRes;
return UintToArith256(bnRes.getuint256());
