Blockchain Developer's Guide

The setting of block-related parameters

In the validation.cpp file, the following parameters should be edited:

• Block value
• Block reward
• Block time
• Difficulty re-target time
• Difficulty re-target scale

The block value should be changed in the GetBlockSubsidy() function:

CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams){ int halvings = nHeight / consensusParams.nSubsidyHalvingInterval; // Force block reward to zero when right shift is undefined. if (halvings >= 64) return 0; CAmount nSubsidy = 50 * COIN; // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years. nSubsidy >>= halvings; return nSubsidy;}
