Adding additional Coins

[duderino999]

Hi,

first of all, great work so far. Using it actually for 32 forks and it's working really stable. There are a few coins "missing", would be great, if they could be added as well.

Chaingreen (unofficial update): https://github.com/morrillup/chaingreen-blockchain
Kujenga: https://github.com/Kujenga-Network/kujenga-blockchain
Lucky: https://github.com/dream80/lucky-blockchain
mELON: https://github.com/mELON-Network/melon-blockchain

Cheers,

I saw that the configs for Chaingreen and Lucky are already existing, but they have not been included within coins_config.yaml, if I add them manually, it looks like they are working.

Thank your for your feedback and references.
coins you mentioned will be tested and ceres will update as soon as they are available.

Chaingreen and lucky are not yet tested, and attributes may be missing

[duderino999]

Great and thanks for taking care of it. There is one additional, that is actually not included and might be worth to implement:

Xcha: https://github.com/xchaio/xcha-blockchain

Thanks for your feedback, and I will go to check if it is possible to include xcha

Xcha: https://github.com/xchaio/xcha-blockchain

unfortunately, after reviewing xcha's code, currently it can not be supported by Ceres, cause they change Chia's message protocol between farmer and harvester.

ok, thanks for looking at it.

Quick question, what are the requirements to add new coins? I tried to add a new one myself, I modified/added following files:

• /ceres/consensus/all_coins_default_constants/xyz_new_coin_default_constants.py (modified this file with the values from the default_constants.py of the fork coin itself)

• /ceres/util/coins_initial_config/xyz_new_coin_initial_config.yaml (modified this file with the values from the initial_config.yaml of the fork coin itself)

• added the fork coin under ceres-initial-coins-config.yaml

Then followed the standard setup with init, init --coins, copy ca and generate_ssl.

After starting ceres, its's giving me a handshake error between ceres and the farmer of the coin. So I am assuming something is missing here or the coin is not compatible with ceres.

[duderino999]

debugging the farmer of the fork coin provides me following message:

2021-11-12T13:09:50.477 farmer farmer_server : DEBUG Invalid connection type for connection 127.0.0.1, while closing. Handshake never finished.
2021-11-12T13:09:50.477 farmer farmer_server : WARNING Incompatible network ID. Maybe the peer is on another network

i was assuming this is related to a wrong mainnet/testnet setup, but when double checking ceres and fork coin, both are set to mainnet.

[hulatang]

pls update to the newest version which fix a bug related to this
thank you.

[duderino999]

yes, did it yesterday ... it's working now as expected. I have also added Kujenga and Shibgreen locally. They are working also as expected. Would be great to add them as well. I have attached the files for your reference.

Quick question on Chaingreen and Lucky. Any chance they will be included within Ceres?

[hulatang]

changreen and lucky can not be supported by ceres like normal, cause they change Chia harvester_farmer message protocol.

in order to make these kind of forks work with ceres, a patch file is needed,
If people would like to override a file under their farmer codes with this patch file, this will be an option

[duderino999]

i can give it a try. can you highlight what exactly needs to be patched?

[hulatang]

some patch files will be supplied for testing

[duderino999]

i just wanted to check, if you had already some time working on the patch files?

[duderino999]

Another one. As you might know, Silicoin has deployed their release with staking and they changed for that the consensus. With the staking functionality the actual Silicoin release is not working anymore with Ceres. Are you planning to fix that, if possible? Or can we assume, that it won't work anymore with Ceres due to their staking functionality. Their latest release is open source again, so might be worth to have a look at it.

[hulatang]

silicoin's code has been reviewed very carefully to check if it is possible to be supported by ceres.
unfortunately ceres can not support silicoin in a standard way.
It will require to modify the silicoin farmer's code by yourself,
I'm not sure if it is worth to do in this way

[duderino999]

it depends on, how much modification needs to be done. always happy to give it a try.

[hulatang]

fine, once is tested I will let you know.
thanks

I have added Goji to Ceres, as it was updated recently. Find attached the relevant files, in case you want to update Ceres.

Hi,

are you still working on this project? Curious to hear, as there hasn't been any updates for a few months. If you are still working on it, there was a hard fork of LittleLamboCoin and the old chain can be threated as abandoned. Would be great, if you could have a look at the new chain and if it can be added to Ceres:
