1  Bitcoin / Bitcoin Discussion / Full node rewards? on: November 12, 2020, 08:53:17 PM
Why doesn't the bitcoin network reward full node runners? I know as an ex-miner that miners do most of the job but since full nodes help propagate the blocks shouldn't they be rewarded something? Running a full node DOES cost money. I mean don't give them 12.5 but at least 0.00001 per day/per unique public IP or something!! We all know that solo mining is a bad idea, so what incentive (other than helping the society and being good [ which doesn't make your wallet happy btw ]) does a full node runner have?Wouldn't we see a faster blockchain if we had more full nodes?
2  Bitcoin / Bitcoin Technical Support / Simple question - Sending BTC to someone from a local wallet on: November 12, 2020, 07:09:33 PM
If I have 1 BTC and I I use "bitcoin-cli sendtoaddress " to send 0.1 to someone, is it true that the rest would be charged as fees and I will be left with nothing? I know this sounds crazy but I read that if one doesn't supply the changeaddress option (OR use the  rawtransaction feature  to set a fee), the remaining goes to the miners.

1 ] Is the above true?
2 ] If it is then if when I send 0.1 out of 1 BTC, I will be left with nothing right?
3 ] Can I use  sentoaddress (and not rawtransaction) along with paytxfee or settxfee and reduce the fees?

3  Alternate cryptocurrencies / Altcoin Discussion / listreceivedbyaddress for ETH on: June 15, 2020, 04:32:17 AM
Under bitcoin-core, when one fires the command:
bitcoin-cli listreceivedbyaddress 1 true
The output is something like:
[ {
    "address": "address-goes-here",
    "amount": 0.00000000,
    "confirmations": 10,
    "label": "label1",
    "txids": [
} ]

What is the equivalent command for Ethereum (geth)?
I just need to know the number confirmations for an ethereum address while it is receiving coins.
I am running the daemon with indexing.. currently testing on rinkeby.
4  Alternate cryptocurrencies / Pools (Altcoins) / Status of Litecoin mining pool on: November 04, 2016, 10:41:25 AM
Somewhere during 2013 a new pool for mining Litecoins called was announced:


I mined a few LTCs and I never withdrew them into a private wallet. It wasn't worth much back then.
Today I tried to visit the website. As expected it's gone and so are my coins I guess.

Was this incident ever announced on the Internet or on this forum? I know a lot of small stratum runners (just like some exchanges)
do the same, pack up, close shop and steal away all the pending payments but I am curious to know
if moved to a different website after announcing it or did they just disappear?  Huh

5  Alternate cryptocurrencies / Mining (Altcoins) / Elevation using a USB Riser on: November 04, 2016, 10:37:10 AM
I have an extra Radeon R9 295X2 box lying around since years !!

After I mount that card onto a USB riser and provide power from the PSU to the card using proper cables (just like the other mounted cards on the mainboard),  do I need to provide SATA power to the card as well?
The riser has a 4-pin power cable to SATA cable. Do I need to use that as well?

Also any suggestions on how and where do I place this bulky card. Is it okay to just keep the card on a table? It has a decent cooling system but I am worried about it's physical  balance.
6  Alternate cryptocurrencies / Mining (Altcoins) / Elevating 295X2 on: December 08, 2014, 08:51:53 AM
I need suggestions on which cable/riser/extender to go for a Radeon 295X2. The mainboard doesn't have enough room for it.
I have heard some of these 'risers' cause fires/burn the board and other circuitry.

If anyone has successfully used a PCI E extender for Radeon 290 series kindly suggest one. Thanks.
7  Alternate cryptocurrencies / Mining (Altcoins) / An optimistic sgminer solo setup on: December 04, 2014, 09:02:15 AM
I am running a recent git pull of sgminer on Radeon cards on a Linux setup.

1] litecoind -server
Previously I had generated 2 LTC addresses using litecoin-qt
So the .litecoin/ directory has the wallet I suppose

2] ./sgminer --url<port_number> -u <my_user_name> -p <my_password>
It detects the GPUs and gives a decent 3-digits Kh/s speed. I set the GPU MAX SPEED var but sgminer still says it hasn't been set.

1] Is this enough (practical) for solo mining Litecoins these days?  Huh
2] Once a block is found will they automatically know to send it to my wallet inside .litecoin or is there another step/command involved?

8  Other / Beginners & Help / Basic confusion between exchanges - buying and selling on: May 15, 2013, 04:58:27 PM
All exchanges BitStamp mtGOX BTC-E all show different rates of Bitcoins at any given point of time.
Is it that when you generate a bitcoin address it is assigned/locked to an exchange?

Because if it isn't so then one may buy bitcoins from an exchange and sell it to another which offers a higher price within minutes.

I am confused how does it work??
9  Other / Beginners & Help / Is nVidia CUDA fooling me? on: May 14, 2013, 06:03:43 PM
I have a single nVidia GeForce 6150SE nForce 430 on Windows 8
I understand GUI miner supports only OpenCL so I am using cudaminer (which I got working after overcoming a few hurdles since nVidia somehow ignores old cards in newer driver files available for downloads]
cudaminer.exe says :

[2113-05-14 2:35:18] 1 miner threads started, using 'sha256d' algorithm.
[2113-05-14 2:35:19] Long-polling activated for http://xx.xx.xx:nnnn

But GPUShark says:
GPU and memory usage
- GPU: 0.0%, max: 0.0%
- GPU memory: 66.5%
- GPU memory controller: 0.0%

So I have 2 questions:

1. Am I making cudaminer.exe use CUDA or atleast the GPU's single GPU cycle or no??
2. Frankly I have never seen 3-digit khash/sec in my life until now! Can I use CUDA with some tool supporting scrypt for mining Litecoins ?


10  Other / Beginners & Help / Solo vs Pools on: May 14, 2013, 11:02:02 AM
I am a part of a public pooled mining for Litecoins. I have engaged 15 workers, each with minimum 4 Intel CPUs, some have 8.
Would it be advisable to do Solo Mining? Will that help me make more profits?

Also is this setup good enough for Solo Bitcoin Mining? This setup does NOT have AMD/NVIDIA GPUs.
