Alternate cryptocurrencies / Altcoin Discussion / Re: How safe are Zero-Confirmation transactions (especially in BCH)?

Hi Abiky,
- first things first. Don't accept a 0-conf transaction if its value is high. Simply wait for some blocks to role by.
- If the tx value is of casual size there's no need whatsoever to wait for any confirmation on BCH. Rollbacks hardly happen. You can check one of many pages doing statistics on it.
- It is not an experimental or new solution on Bitcoin Cash. It was already used on Bitcoin before Bitcoin Core activated Replace-By-Fee (RBF). Thus it is a well tested on Bitcoin in general.
- RBF undermines 0-conf when the blocksize is limit and demand is high. This situation leads to very long confirmation times and thus provides an easy way to double-spent your coins. BCH don't have this problem, only BTC has it.
- RBF has been deactivated on Bitcoin Cash because 0-conf are very useful. I would suggest to simply try it out yourself with services like BitPay, SatoshiDice or whatever service (there are plenty).
To sum it up: a blockchain has to make the choice between Replace-By-Fee and 0-conf tx. Bitcoin Core goes for RBF, Bitcoin Cash goes for 0-conf.
This is my first post here after more than six years. Let's see how spirits are in here these days.

Economy / Economics / Supply and Demand - Simple question to a chart
|

Hi, not paying any attention to bitcoins lately, I know realize how its marketprice has risen since november or mid january. Trying to understand this I looked at this graph: http://www.bitcoinx.com/charts1/depth_mtgox.pngand I find myself with two questions: Do I interpret correctly that the red chart reflects the amount of BTCs people ask for / would like to buy? If that is so, why does BTC price rice with declining demand? Or am I indeed confusing ask and bid sum here? Why do the graphs seem to have a synchronized or even an axially symmetric signal/part to their trends? Thank you Luigi |

/usr/bin/ld: cgminer-adl.o: undefined reference to symbol 'dlopen@@GLIBC_2.1'
[...]
libdl.so: could not read symbols: Invalid operation
Can anyone help me on this? I have all *.h files from the AMD-ADL-SDK copied to the corresponding folder. configure-procedure went through just fine ------------------------------------------------------------------------
cgminer 2.0.7
------------------------------------------------------------------------
Configuration Options Summary:
OpenCL...............: FOUND. GPU mining support enabled
ADL..................: SDK found, GPU monitoring support enabled
ASM..................: true
Compilation............: make (or gmake)
CPPFLAGS.............:
CFLAGS...............: -O2 -Wall -march=native
LDFLAGS..............: -lpthread -ldl
Installation...........: make install (as root if needed, with 'su' or 'sudo')
prefix...............: /usr/local
I tried both... the latest git sources and the tarball provided. Hmm - have you actually installed the SDK as per the instructions?
(and what version of the SDK did you install?)
AMD APP SDK 2.4 I do not have ADL SDK installed - just took the *.h files as supposed by the instructions. Version 3.0 |

Bitcoin / Mining support / Re: a miner/program that can limit GPU resources bitcoin can use?

Hi,
any novelty on this topic? Is any of the standard miner capable of limiting the GPU usage?
I just don't won't my gpu to work under high stress when I'm around . It gets the cooling started which creates a hell of acoustic smok.
Tried to play around with phoenix's AGGRESSION or poclbm's getwork-rate but I guess that's not the way to go. Would process priority under linux make sense?
Bye
