Documentation and confusion

[binaryf]

Describe the bug

Everything runs smoothly except "eth_sendTransaction".

According to https://github.com/oliverw/miningcore/wiki/Coin-Daemon-&-Wallet-RPC#ethereum
you can run go-ethereum (geth) with:

$ geth --cache 1024 --mine --http --http.port 8545 --unlock --password --allow-insecure-unlock

Mining works fine.
But after a mined block, I get an error when Miningcore should reward the miners on the pool.

Miningcore says "System.Exception: eth_sendTransaction returned error: invalid sender code -32000"
Geth says err="invalid sender"

I can transfere founds in the go-ethereum javasript console.

Have I forgot something here ?

To Reproduce
Steps to reproduce the behavior:

1. Setup go-ethereum according to documentation.
2. Setup Miningcore according to documentation.
3. Run mining on Miningcore.
4. Find a block.
5. No payment for miners due to error in configuration.

Expected behavior

Mining and payment should work by following instructions or manual.

Screenshots

I can provide screenshot If needed, or any other information.
Maybe this is something that others also run into,
and can be fixed by providing a little more information.

Platform and software

• Ubuntu 22.04 LTS
• Latest Miningcore.
• Go-ethereum (geth) v1.20.1-beta (https://github.com/ethereumpow/go-ethereum/releases)

Forgive my ignorance but isn't this question purely academic as of yesterday?

[binaryf]

Maybe it is a bug ?

[oliverw]

Maybe it is a bug ?

Its most likely a bug but what is the relevance after yesterdays merge?

[binaryf]

Ah! Got it! :)
Have a pool 90% set up for ETHPOW fork :)

[oliverw]

Ah ok. Will look into it in a bit.

[binaryf]

Let me know if you need more info.
Thanks!

We also had an issue with miningcore when miningcore tried to pay miners more than the incoming balance in the base wallet.

It is possible that this was an issue (behaviour) beacause of a little messy dev-setup and the back and forth trying to get things working.

But it is very strange that miningcore are reporting reward: 5 when the ethereum pow block explorer says about 2 ether.

Here is the link to the dev setup: http://miningpool.no:4000/api/pools/miningpool1/blocks

UI is at http://miningpool.no/

You might want to look into this if this is related to the ethereum pow fork witch launches soon.

So it was an uncle identified as a full block?

[binaryf]

I need to see the block explorer to be sure.

https://iceberg.ethwscan.com/blocks

But it is down at the moment.

[binaryf]

Looks like the block explorer for the testnet is permanently down.

It should be easy to reproduce. I can make a compact list of steps.

[binaryf]

Block reward should be 2.00 ETHW.

[totom9000]

Work Great here. Its actualy 2ethw +netfee so it can be higer and you have unicles that is less and orphan 0.

[oliverw]

Block reward should be 2.00 ETHW.

What coin are we actually talking about?

[binaryf]

Ethereum POW (ETHPOW, ETHW)
