Consensus issue, sync. stuck at "Synchronizing sporks - 25%" - PIVX fork

Consensus issue, sync. stuck at "Synchronizing sporks - 25%" - PIVX fork

I've been working on a PIVX fork for some time, to better understand blockchain infrastructure and coding in general. I have been able to modify all parameters, remove checkpoints, set up a new genesis block for blockchain and both enable PoW & disable PoW/switch to PoS and masternode succesfully.

I am somewhat stuck however, on this last piece of the puzzle - spork synchronization. After setting up a seed node, I can continue synchronization from 12% to 25%, yet it will never go past that instance.

The feeling I have is that it has to do with spork activation times (in spork.h), yet changing these values around have not worked in getting the synchronization to complete. I am aware that I may not understand how those sporks are supposed to synchronize well enough, so I hope someone can point me in the right direction.

Any help is much appreciated.

Looking through masternode-sync.cpp, I find these instances:

    case (MASTERNODE_SYNC_SPORKS):
    RequestedMasternodeAssets = MASTERNODE_SYNC_LIST; 
    break;
[....]
    BOOST_FOREACH (CNode* pnode, vNodes) {
    pnode->ClearFulfilledRequest("getspork");
[....]
    if (mnodeman.CountEnabled() == 0 ) {
        if(syncCount < 2){
            Reset();
            syncCount++;
        }
    } else
        return;
[....]
    if (RequestedMasternodeAssets == MASTERNODE_SYNC_SPORKS) {
        if (pnode->HasFulfilledRequest("getspork")) continue;
        pnode->FulfilledRequest("getspork");

        pnode->PushMessage("getsporks"); //get current network sporks
        if (RequestedMasternodeAttempt >= 2) GetNextAsset();
        RequestedMasternodeAttempt++;

        return;
[....]
        //set to synced
    if (RequestedMasternodeAssets == MASTERNODE_SYNC_SPORKS) {
        if (pnode->HasFulfilledRequest("getspork")) continue;
        pnode->FulfilledRequest("getspork");

        pnode->PushMessage("getsporks"); //get current network sporks
        if (RequestedMasternodeAttempt >= 2) GetNextAsset();
        RequestedMasternodeAttempt++;

        return;
    }

They seem to corrobarate that is indeed a lack of nodes; it seems at least 2 nodes needed in order to complete syncing the sporks?

Activation of SegWit v1

Activation of SegWit v1 The segregated witness soft fork of August 2017 included a versioning field which would allow for future incrementation. Anthony Towns has recently posted an early draft of the proposal for the SegWit v1 upgrade to the mailing list . Although the devil is of course in the details, how could such an upgrade process look like? What are the different upgrade mechanism for the major [v1 - v16] and minor [v1.0 - v1.127] version changes? How is the soft fork signaled? How is the consensus change enforced? Is the v1 change as "contentious" and time consuming as v0 was? What are the tasks of node operators and miners? Thank you in advance for the answer! https://ift.tt/2VrPDpG

Nonce usage in ECDSA signing algorithm

Nonce usage in ECDSA signing algorithm I'm trying to understand the signing function secp256k1_ecdsa_sig_sign(), and I'm curious about the nonce usage here. static int secp256k1_ecdsa_sig_sign(const secp256k1_ecmult_gen_context *ctx, secp256k1_scalar *sigr, secp256k1_scalar *sigs, const secp256k1_scalar *seckey, const secp256k1_scalar *message, const secp256k1_scalar *nonce, int *recid) { unsigned char b[32]; secp256k1_gej rp; secp256k1_ge r; secp256k1_scalar n; int overflow = 0; secp256k1_ecmult_gen(ctx, &rp, nonce); secp256k1_ge_set_gej(&r, &rp); secp256k1_fe_normalize(&r.x); secp256k1_fe_normalize(&r.y); secp256k1_fe_get_b32(b, &r.x); secp256k1_scalar_set_b32(sigr, b, &overflow); /* These two conditions should be checked before calling */ VERIFY_CHECK(!secp256k1_scalar_is_zero(sigr)); VERIFY_CHECK(overflow == 0); if (recid) { /* The overflow condition is cryptographically unreachable as hitting it requires f...
