Generating first block after genesis block in PoS altcoin

Generating first block after genesis block in PoS altcoin

I'm currently developing a test altcoin in educational purposes, and can't for some reason generate first pow blocks after generating genesis block. Couple of years ago i successfully made workable fork of fork of dash (or something similar with terribly outdated codebase), but I'm totally unable to reproduce it with modern codebase.

So, to the point. I used PIVX repo, changed chainparams.cpp accordingly:

  • removed old checkpoints;
  • generated new keys;
  • updated ports all over the codebase;
  • changed pchMessageStart numbers;
  • updated unixtime;
  • changed coin name all over the codebase;
  • generated genesis (and it was correct, i checked it many times);
  • compiled it;
  • launched coind;

  • launched cpuminer, and it failed with the following in log:

    2019-02-28 16:55:09 ERROR: CheckProofOfWork() : hash doesn't match nBits
    2019-02-28 16:55:09 ERROR: CheckBlockHeader() : proof of work failed
    2019-02-28 16:55:09 ERROR: CheckBlock() : CheckBlockHeader failed
    2019-02-28 16:55:09 CreateNewBlock() : TestBlockValidity failed

I re-generated genesis with code in chainparams.cpp - it was the same as with genesis generator. I tried gen=1 and setgenerate true, and again received the same error, and hashespersec=0 in getmininginfo.

I started searching the web, and found a lot of same questions without any answer. For example, this one looks absolutely same - Cannot mine Genesis / First Block (PIVX Fork / Clone)

I tried the kind of solution from this thread - https://bitcointalk.org/index.php?topic=2152157.0;prev_next=next - but without any success too.

I assumed that maybe i'm missing something, and tried to do the same with some other PIVX forks. The first one was this - https://github.com/IchibaCoin/ICHIBA - with the same error. The second one was this - https://github.com/cruxcoinsource/CruxCoin - with the same error too. Then i scratched my head, thought deeply, and run diff for all files in /src/ folder of both coins with my testcoin. Files were totally same and differed only where they were different between crux and ichiba.

I tried all possible combinations of bools in this part of chainparams.cpp:

fMiningRequiresPeers = true;
fAllowMinDifficultyBlocks = false;
fDefaultConsistencyChecks = false;
fRequireStandard = true;
fMineBlocksOnDemand = false;
fSkipProofOfWorkCheck = false;
fTestnetToBeDeprecatedFieldRPC = false;
fHeadersFirstSyncingActive = false;

And when fMineBlocksOnDemand was set to true, command setgenerate true returned that wallet keypool is empty, and keypoolrefill command had no effect.

What am i doing wrong?..)))

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

How to check if Electrum is masking my IP with the Tor proxy?

How to check if Electrum is masking my IP with the Tor proxy? When i start Electrum from the command line i see this mensage: (python3:7069): dbind-WARNING **: 14:09:58.452: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken What does it mean? I just installed Electrum following this tutorial: http://docs.electrum.org/en/latest/tor.html I followed the instructions from this topic " Option 2: Multiple servers but Tor Main ". I installed Electrum using the command line on Ubuntu, check the " Installation from Python sources " on this link https://electrum.org/#download if you want to see the codes. And i used this code bellow to download the Signatue keys: $ gpg --keyserver pool.sks-keyservers.net --recv-keys 2BD5824B7F9470E6 I checked the both checkbox: 1)...

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password I used btcrecover to extract the wallet file (wallet.aes.json) from a blockchain account and I have been running btcrecover with dictionaries of my making but it has been going on for weeks and I am running out of ideas on how to permutate what my wife and I think the password could have been. Is there a way to just manually transfer the btc from the old wallet into a new wallet we do have access to or is there any way to extract the password or private keys directly from the wallet file? We have: the phone with the original wallet app installed, the wallet file pulled using btcrecover, access to the email to allow authorization to access, the wallet identifier that was sent to her email when she first signed up, the phone which has the wallet, the pin that was used for the wallet, and we know how much btc is in the account. We do not have: The pri...
