Re: Taking the BCH out without fulfilling the node

I know the address that I hold bch in, but only bch, not bitcoins. How do I export the private keys from Bitcoin unlimited node?
Open your Bitcoin Unlimited wallet and do the following:

1. Help -> Debug Window -> Console.
2. If your wallet has a password write: walletpassphrase "your password" 600
3. To export your private-key, use: dumpprivkey "your BCH address"
4. Copy the result. That's your private-key.

Go to Electron Cash:

1. Import Bitcoin addresses or private keys -> Paste your private-key from step 4 -> Next.

Wow I was looking for this! Thanks a lot, I managed to import the private keys.

Cheers

Electron Cash[1] is a lightweight SPV wallet.

Unlike Bitcoin ABC, you don't need to download the whole blockchain before spending your coins.

Electron cash crashes when I try to run the .dat backup wallet file, even if I run it as administrator. What else can I do ?
Do you know which adresses hold bitcoin cash balances? Simply import the wallet.dat in a bitcoin wallet, or where it originially came from, find the adresses that held bitcoin at the time of the fork (and now bitcoin cash), and export their private keys in a bitcoin cash compatible wallet, -- instead of importing the entire wallet.dat... ?

Taking the BCH out without fulfilling the node
by

Hello there,

I have a small problem. I have a bch wallet with little bit of bch in it that I want to sell. However, the node that the wallet belongs to is taking too much time to sync. I have been waiting a month now it has not even moved a year, since the computer is old and cannot process very large amounts of data.

So I am asking how to use this bch without fulfilling the node completely? Is there a way to open the wallet in some website ?

Thanks!

Re: Electrum transaction stuck on Replaceable

Hello,

I recently made a small transaction with quite a low fee of 6 satoshi per byte. The transaction is not urgent hence the low fee. However, it has been more than a day, how long will it take the transaction to be relayed? Since I cannot bump fees, I need to wait it out I guess. Electrum does not let me bump fees with a error saying "could not find suitable outputs". What should I do at this point?

Thanks

Can you post the TX. Right click the transaction > " view on block explorer" and copy and paste the link here.
It's probably either an error in electrum.

TX id is 4c2519b434fff48e4e02764a7d2ebc94d95f32e5fc44805259e7b97677b9eff0

Re: sound proofing for avalon 741 ,or 721 or 6

I wanted to go into ASIC mining a couple of months ago, had a Antminer S9 in my basket and filled down my information but then I saw a video on YouTube about the noise they produce. Never thought it would be that loud, so did some tests in my study room with a device that makes an equal amount of noise and found it too loud so I canceled the order. The Avalon seems a little bit more quiet, but still too loud for the apartment I live in. The noise reducing you did seems to be going to the right direction for me. But I just hope that they will produce quieter machines in the future, so an average person can also enjoy ASIC mining.

It will certainly make your avalons quiter, but not enough to sleep in the same room. You can for example put this into your living room instead, with the idea I and philip described above. The problem is always the fan, but it is required to cool these machines down. Thus, your idea of a quiet ASIC machine is not feasible because it makes the miner much expensive, see r4 from bitmain, it has almost the hashrate as avalon but 2 or more times expensive. Water-cooled machines would make it much more expensive.

I have been also recently experimenting with silencing the deadly noisy avalons. I have found out that if you live in a cold country ( for example in Sweden now the outside temperature is just 3 degrees), you are lucky and dont need to do much.

Here is what I have done to noise solution: Although avalon 741 has only one fan, you can still be able to put a hose to both sides of the miner, and it makes the fan work a slighty bit higher (in my case only 10 percentage points), but the total noise reduction will be around 20 dBs. The hoses I have used were both fire safe and highly sound-proof, surrounded with extra insulating material (a yellow woolish material with soft texture). I have put the intake hose to outside through a small window to take in cold air, and have put the longer hose to inside to heat my room. The longer the hose, the better the sound-proofing, so its a good idea to put the longer hose to the front of the miner, rather than the backside, because it is farther away from the fan. For further noise reduction, you can tape the small cleavages around the miner fan to reduce noise passing through

Can anyone tell me what "GHS asc" means vs GHS av (which I assume means a average over some period of time)?

Was wondering about that also.

That would only be a problem if the miner isn't mining but the fans are still running. The heatsinks get hot enough to almost boil water during regular operation.

Then why do some manufacturers put minimum working temperatures like -5 or -10? From your perspective, the miners could run even on -40. I do not think the heatsinks will get that hot under such extreme temperatures even if the mining process is on.

And possibly under such temperatures, only the board itself will retain heat, and heatsinks will be cold

Another possible problem I could think of is that water in the air passing thru the heatsinks could freeze at some point, and continue freezing until no more air can pass through the miner. I think it is possible even if the air is moving fast

Do any of you have good experience using the voltage offset +1 option? Do you see any improvement in hashrate or is it just waste of electricity?

Sometimes on this option, I do get a reduced hashrate instead of an improvement.

0 and -1 work well. 

+1.  Not good.  Most likely a hot psu is need .ie 12.5 volts on the button

What kind of hashrates can you expect from those voltage settings?

Right now at 0, I'm getting:

Hash Rate
GHS av: 6536GHs
GHS asc: 7412GHs

Seems low to me?

Yes its sort of low, I have those hashrates on -2 offset. however on 0 setting, my average almost tops 8 t/h

Hello,

I am new to the pool. Currently I have an avalon 741 pointed at the solo pool, hashing around 9 TH/s. I was wondering how do you find it out if you find a block? does it say it somewhere on the user stats page?
The reward appears immediately in your wallet, your stats bestever share will be better than current network diff, it will be announced here on the thread, and any wallet monitor such as an online one would inform you of the reward payment.

Hmm... what if a block is found by me and not rewarded to me?

P.S is it really that hard to find a block by yourself?
