He creado un nuevo bloque de Génesis . ¿Qué valores se deben asignar a estos campos?
namespace Checkpoints
{
typedef std::map<int, uint256> MapCheckpoints;
struct CCheckpointData {
const MapCheckpoints *mapCheckpoints;
int64_t nTimeLastCheckpoint;
int64_t nTransactionsLastCheckpoint;
double fTransactionsPerDay;
};
La asignación original de puntos de control para la red principal se puede encontrar aquí: https://github.com/bitcoin/bitcoin/blob/v0.10.2/src/chainparams.cpp#L55-L77

Puede generar varios bloques y colocar pares (block_height, block_hash) en el siguiente campo. O simplemente elimine todos los puntos de control :)
static Checkpoints::MapCheckpoints mapCheckpoints =
boost::assign::map_list_of
( BLOCK_HEIGHT, uint256S("0xBLOCK_HASH"));
static const Checkpoints::CCheckpointData data = {
&mapCheckpoints,
bitcoin-cli getblock [last checkpoint block], then get the unix time, // * UNIX timestamp of last checkpoint block
Write a script to count?, // * total number of transactions between genesis and last checkpoint
// (the tx=... number in the SetBestChain debug.log lines)
estimate_a_number // * estimated number of transactions per day after checkpoint
