[Solved] Is there a mining tutorial for mainnet?


Hi friends,

is there a mining tutorial for mainnet? I followed the tutorial https://blog.aeternity.com/tutorial-mining-ae-on-ubuntu-18-04-f4d1f908b0fd and try to set up but didn’t success. I defined the epoch.yaml and run command to test it but encountered the error “yamerl_parsing_error, error, “Block mapping value not allowed here””.

I want to use CPU mining based on AE mainnet. any help?

thanks in advance.


It looks like your epoch.yaml file is misconfigured. Could you please paste the mining section of it?


Hi friend, yes, solved already. thx.


BTW, how to involve multiple CPU cores to mine? friend.


The field extra_args in epoch.yaml can contain an option -t N where N is the number of threads/cores to use by the cpu-miner.


after i added this:

beneficiary: “ak_47wX83aFZTNmjcHAMohgPfp3GrAuiiMqoK13Ckmp6Cn7tHi43”
autostart: true
executable: lean30
edge_bits: 29
extra_args: “-t 6”

the mining will throw error said “2018-11-30 20:34:19.906 [error] <0.1267.0>@aec_conductor:handle_mining_reply:718 Failed to mine block, runtime error; retrying with different nonce (was 1746218179646316195). Error: {execution_failed,{status,127}}”

do you know why?


It should be lean29 I think :thinking:


I tried but without success. the error is “2018-12-01 00:27:20.550 [info] <0.3324.0>@aec_conductor:add_synced_block:150 Header failed validation: incorrect_pow”


That error suggests there is a problem with your configuration. Could you post the whole configuration? The relevant bits for incorrect_pow should be expected block time and edge_bits


Hi friend, the executable parameter should be “mean29-generic”. and the mining program keep running a whole night. but I didn’t see any mined block via command “grep “mined” log/epoch_mining.log*” to check. is this normal?
CPU model is below.
vendor_id : GenuineIntel
cpu family : 6
model : 62
model name : Intel® Xeon® CPU E5-2680 v2 @ 2.80GHz
stepping : 4
microcode : 0x42c
cpu MHz : 2799.999
cache size : 25600 KB


The mining power of the network is strong enough that you should not expect to mine a block using CPU-mining ‘in a night’. You could get lucky of course, but normally it will take longer.
