Topic: Quickly setting up ofline solo litecoin mining (Read 727 times)
OK, I thought the miner mined and the wallet verified. But since they're both open source somebody could tweak a wallet to let bogus coins through. Oh well, maybe I'll get a power supply built and my solar panels remounted with all this offline time.
There is no way how to mining live in offline mode. Every found block must be verified with another nodes, so you must have acces to internet and have another nodes connected to your private node.
liecoin is asic territory don't mine with gpu or cpu, waste of time, and it's better to mine in pool, because i think solo isn't working on litecoin like with bitcoin, they removed the possibility in the wallet
I expect to lose my internet connection for a week or so starting tomorrow the 15th. It would be really handy if my scrypt ASIC could be doing offline solo litecoin mining while I'm disconnected. I think it isn't terribly complicated and I'm most of the way there, I just have a few specific questions. I don't have a lot of time left to RTFM more right now. I've been Googling and pulling bits and pieces from here and there. I had the litecoin core installed and electrum-ltc. I'm using Raspbian Linux on a Raspberry Pi. I started:
Q: What protocol does this speak, does it know stratum+tcp natively? Or do I need another layer? I do have a stratum proxy installed and working (Slush's) I could redirect to feed machines on my lan, I haven't added that piece yet to keep it simpler
Q: Can I use something non-gui here instead of litecoin-qt? (litecoin-cli, litecoin-tx, litecoind)
Q: Can I mine at that but keep my electrum-ltc open?
My litecoin.conf as of now:
I did: litecoin-tx -create
and it said: 01000000000000000000
I'm not sure what that does but it seemed to help a little.
I can do:
netstat -l output | grep 9332
tcp6 0 0 [::]:9332 [::]:* LISTEN
so I know the port is opening.
I've tried to test with cpuminer since it's on the same machine, cgminer and my asic are downstairs.
./minerd -a scrypt --threads=1
and experimenting:
Q: Am I oversimplifying this, thinking I can point miner software at litecoin-qt as though it were a pool?
Q: Do I need to download the whole blockchain first? Impractical: overright I only got 41562 blocks, I'm still 5 years behind.
Q: I do have nginx running on port 80 and Apache on port 8087, are those complicating things? I thought all this was on 9332.
If I could get offline solo mining working it might help in general later because I only have a slow connection through a cell phone, mining bogs it down with the extra traffic.
