new altcoin, node stoped progress after loading genesis block
by
marvic4
on 24/02/2025, 17:42:44 UTC
Hello,

Node stopped progressing after loading the genesis block, and it's just flushing fee estimates every hour. That means it's stuck and not verifying blocks properly? This coin is forked from bitcoin 28.x.

@pooya87 , @DaCryptoRaccoon Thanks for replay, need to generate genesis hash using Randomx. How to generate it any tool to do? or any source code to do it? just genesis hash only. Yes, older version better to create, but using RandomX hash not using SHA256

Setgenerate removed from latest source?
by

on 08/09/2020, 15:58:23 UTC
Hello,

In older versions of POS staking coins these commands use to work perfectly(./coin setgenerate true).
Code:
#ifdef ENABLE_WALLET
        /* Coin generation */
        {"generating", "getgenerate", &getgenerate, true, false, false},
        {"generating", "gethashespersec", &gethashespersec, true, false, false},
        {"generating", "setgenerate", &setgenerate, true, true, false},
#endif

Code:
#ifdef ENABLE_WALLET
        /* Coin generation */
        {"generating", "getgenerate", &getgenerate, true },
        {"generating", "gethashespersec", &gethashespersec, true },
        {"generating", "setgenerate", &setgenerate, true },
        {"generating", "generate", &generate, true },
#endif

Code:
#ifdef ENABLE_WALLET
        /* Coin generation */
        {"generating", "getgenerate", &getgenerate, true, {} },
        {"generating", "gethashespersec", &gethashespersec, true, {} },
        {"generating", "setgenerate", &setgenerate, true, {} },
        {"generating", "generate", &generate, true, {} },
#endif

This is removed from (CRPCCommand command []) Latest, new version of POS coins.

When I try to add the in net.cpp or server.cpp it giving error says "could not convert"

Code:
rpc/server.cpp:258:1: error: could not convert ‘{"generating", "setgenerate", , {"true"}’ from ‘’ to ‘CRPCCommand’

another way I tried
Code:
rpc/server.cpp:259:1: error: could not convert ‘{"generating", "setgenerate", , true, true, false}’ from ‘’ to ‘CRPCCommand’

How to solve this? Did they removed the code?

Thanks.

Re: Need Math for Halving Interval and Subsidy

Code:

{
    ...
    // Force block reward to zero when right shift is undefined.
    if (halvings >= xxx) --------------Sample
        return 0;

That should be the following regardless of any of the parameters:

Code:
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    ...
    // Force block reward to zero when right shift is undefined.
    if (halvings >= sizeof(nSubsidy) * CHAR_BIT)
        return 0;
    ...
}

In Bitcoin Core, they use the literal 64, which is ok until something changes and then it becomes a bug.

Thanks for replay.

Exactly 7391250, but you can round it to 7400000.
4 years = 126144000 seconds
126144000/600 = 210240 blocks per halving
30 years = 946080000 seconds
946080000/128 = 7391250 blocks per halving

Can I use MainNet data( Merkle, Genesis, epoch, nounce) to Testnet and RegTest?

No, due to various reasons such as different address format & genesis block on testnet are different.

Thanks, I used source code to generate Genesisblock hash, with different PCH message and other values for all three.

For Mainnet and TestNet it crated same Nounce, Markel and Genesis Hash values. But different values for RegTest.

when you keep getting stuck on basic things such as creating genesis block, mining a new block, setting block rewards, total supply,... (according to your post history) then maybe it is a sign that you are on a wrong path and should start by first learning what each of these topics you struggle with are and why they are designed like that instead of just trying to change variables and see which one works to create a new altcoin that has been created thousands of times before in the same exact way.

Thanks, for reading my previous posts, I am aware of basic things how to fork a coin(Older versions, few coins launched). But not expert Like YOU.
 
Those forked coins have lots of problems (newer versions ). I used to have Genesis tool generators,  which work for some coins and won't work most of the coins. That is main thing (tool generator)

That is the reason why i ask a question here. If your not interested in answering it is fine.

Now I asked simple Math,  Some one will help. I do help many devs.

Thanks.

What version did you compile?

As far as I remember BTC no longer uses hardcoded checkpoints but this is for block 0 so it might still be checking for that.
You can probably google around for that.

Beyond that I have no idea, you will have to wait for a few more knowledgeable people to pop in.

Latest version I think, cloned from repository with --recursive.

Can I use MainNet data( Merkle, Genesis, epoch, nounce) to Testnet and RegTest?

It's actually #2 in a series of 6. I think in this one he discusses what you need to do to generate the genesis block.
Might be in a later one, but they are all short videos that you can watch to see if you missed anything.

-Dave

Thanks, I know this video(saw all 6 before), saw this before for Scrypt based Litecoin.

I need SHA256, After google, found few generators (GENESIS0), but this will generate one at time MainNet or Testnet or regression.
Which will have different epoch time, Merkle, Geneisblock hah etc.

But In Bitcoin, Litecoin or any other coin all the 3 nets(Main, Test, reg) have same Merkle and Epochtime.

Using Chainparams.cpp It will generate 3 Genesisblocks(Maine, Testnet, Regre).

How to do in that way.
