Hi,

I have been following this tutorial (https://bitcointalk.org/index.php?topic=5134256.0) to play around with a forked version of Bitcoin 0.18. I have created the genisis block and was looking to mine it via RPC using a Gekko NewPac I had laying around using this version of CGminer (https://github.com/vthoang/cgminer.git) which i have compiled on my pi.

After around 5 mins both nodes reported over 1600 blocks had been mined, but when I checked the balance of the wallet in the fork of QT it was zero. I checked bitcoins balance via RPC and the available balance was 0, I then checked the total supply via RPC and the coins were generated but obviously sent somewhere else as they weren't in the wallet.

Any help is appreciated as I cant make head nor tail of it and my Cpp is not the best.

Cheers

Hi, I have been following a tutorial (https://bitcointalk.org/index.php?topic=5134256.0) to fork the Bitcoin codebase, I have everything up and running with 2 instances and have even managed to get CGminer working with the local node and a spare NewPac stick I had lying around.

For some reason, when the coins are mined they are not showing in the balance of the recieving wallet, even after 1000 blocks.

I'm trying to learn but I've been scratching my head for a good few days and wondered if anyone might be able to help.

Cheers

Sorry if this should be elsewhere but the level of technical detail in the main pollard kangaroo method thread is far beyond my level of technical understanding.

I just want to check my understanding and see where I might not have a good grap of the basics before proceeding. My assumptions are below;

* The pollard kangaroo method can drastically reduce the amount of work required to obtain the private key from the public key but requires the public key as an input to do this.

* Once an address has spent some of it's funds that address public key is revealed in the spend transaction.

* The funds which are not spent are returned to a change address leaving a balance of 0.

* The address should not be reused as a malicious actor can start generating the private keys from the moment the spend transaction is confirmed.

Feel free to correct any of the above points but if the above is correct; can anyone answer the following;

* Address reuse was extremely common in the early days and there are several addresses with 1000+ BTC balances with outgoing transactions revealing the public key.

Why has this not been used to steal the funds?

I'm sure there is a limiting factor to this method but I could do with it being spelled out in layman's terms.

Cheers.

I'm attempting to set up CGminer using my own full node for fun / education / lottery, I know the chances are well below zero but figured I'd give it a go.

Software

Bitcoin-qt v 0.20.1
CGminer v 4.11.1

OS

Debian 5.4.79-v7l+ armv7l
 When running using the below command for CK pool everything works fine,

/usr/src/cgminer/cgminer -o stratum+tcp://solo.ckpool.org:3333 -u bc1qgh7q8kceh4289xehdy8mmjfsp74rzg4fsemtj5 -p x

When run with the below command for solo mining,

/usr/src/cgminer/cgminer -o http://localhost:8332 -u 12345 -p 12345 --btc-address bc1qgh7q8kceh4289xehdy8mmjfsp74rzg4fsemtj5

I get the following response,

Pool 0 JSON failed to decode GBT

I have tested the getblockinfo with the segwit rule via bitcoin-cli and it appears to be working fine, this leads me to believe it is either a config or version issue but I can't figure it out.

Any help appreciated

Phil
