What if I have a real WIF that's missing, say, the last 12 characters ? Tongue

change in WIFRoulette.cpp to be:

Code:

using namespace std;

#define ROOT_LENGTH 12

alignas(64) const char BASE58[] = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz";

const char WIF_START[] = "KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qd7sDG4F";

class Timer {

remove "static const char VALID_PREFIXES[][3]" , static constexpr size_t NUM_PREFIXES and "void generate_valid_prefix" from script.

change "void init_batch(WIFBatch& batch, int batch_size)" to:

Code:

void init_batch(WIFBatch& batch, int batch_size) {
    thread_local Xoshiro256plus rng([]() {
        static atomic<uint64_t> global_seed(chrono::steady_clock::now().time_since_epoch().count());
        uint64_t seed_value = global_seed.load();
        global_seed.store(seed_value + 1); 
        return Xoshiro256plus(seed_value);
    }());
    char random_root[ROOT_LENGTH + 1]; 
    for (int b = 0; b < batch_size; ++b) {
        generate_random_root(random_root, ROOT_LENGTH, rng);
        memcpy(batch.wifs[b], WIF_START, strlen(WIF_START));
        memcpy(batch.wifs[b] + strlen(WIF_START), random_root, ROOT_LENGTH + 1);
        memset(batch.extended_WIFs[b], 0, 64);
        batch.extended_WIFs[b][0] = 0x80;
        batch.extended_WIFs[b][33] = 0x01;
    }
}
