321  Alternate cryptocurrencies / Altcoin Discussion / Re: If you were to implement a CPU-only coin... on: July 29, 2013, 10:00:30 AM

In an ideal world, bot nets would be useless for mining coins.  Problem is, you'd have to have something like a captcha that could not be faked.  That way each person would be equal, none of this 'He who has the most cash/bot-net/farm/whatever wins'.


The bot net would set up a site with naughty pics, for free but surfers must solve a captcha to see them,
then let the surfer solve your captcha. This was a new bot trick in 2007   Roll Eyes

I guess it would be trivial to port this over to Tenebrix.

I haven't tried yet but would be surprised if it's not trivial:

- PUBKEY_ADDRESS in base58.h (Ltc: 48, Tbx: 127, Fbx: 95)

- checkpoints.cpp

- hashGenesisBlock, nSubsidy, nTargetTimespan, nTargetSpacing and
  pchMessageStart (magic network number, Ltc: 0xdbb6c0fb, Tbx: 0xd9b4daf9, Fbx: 0xdbf9dbf9) in main.cpp

- the Genesis block in main.cpp

- GetDefaultPort in protocol.h

- config file and data folder name in util.cpp
  Name of the executable in bitcoin.pro
  Name of the ".pid" file in util.cpp

This should be enough for basic function, unless some blocks fail the security tests
(like block 3075 in Fairbrix) and need an exception.

- pnSeed in net.cpp

Perhaps we should bring back IRC node discovery, it seems reliable (once again).

323  Bitcoin / Development & Technical Discussion / Re: Implementing Oracle Contracts - Feedback Requested on: July 27, 2013, 03:04:33 PM

Another reason is that you want to be able to process arbitrary data, like by downloading a web page. Otherwise your oracle has to be specifically programmed to know about every possible kind of event, which sucks. Now, what the hash-checking scripts design does is let you have an arbitrary program structured like this:

Code:
var event_a = get_nonce(0);
var event_b = get_nonce(1);

if (wget("...").contains("blah")) {
  reveal(event_a);
} else {
  reveal(event_b);
}

Another way to process arbitrary data is to regularly publish a list of questions
and ask miners to act as arbiter by encoding a few extra bits per block. Vanitygen abuse perhaps?

Assuming it's about typical general interest prediction market stuff like
Dems win/Reps win, BTCUSD higher/lower than last year, major city nuked/not nuked, etc.

What percentage of pools, and miners voting by proxy, would participate?
Can be a small minority, just significantly more than those who would actively sabotage it
and you have your oracle built directly into the client with no need to access outside data sources.

Or maybe some flunkies are just being paid per MB of anti-BTC video uploaded and their handlers either don't notice or don't really care.


This, or... gold bugs gone mad?
The "doing the exact same fucking thing over and over again. Expecting shit to change" kind of insanity.

325  Alternate cryptocurrencies / Altcoin Discussion / Re: Updated Fairbrix Client on: July 24, 2013, 07:13:25 PM
I found a Fairbrix client based off of 0.6.3
Very old version actually. Wink

New one is this: https://github.com/wiggi/fairbrix-0.8-coincontrol-test
Nothing really interesting, mostly a 1:1 conversion of the current Ltc development version with coin control.


Notes:

v0.8 complains about using just "1" for both username and password, so something like this
Code:
# bitcoin 0.8 requires rpcpassword != rpcuser
rpcpassword=foobar
rpcuser=1
rpcport=8645
server=1
is needed in fbx.conf

Stable nodes:
Code:
addnode=54.245.186.179
addnode=198.154.60.61

If you allow incoming connections (i.e. open port 8591)
don't use "maxconnections=...". It's buggy and prevents peers from dl'ing the blockchain.

I did some obvious tests: dl/reindex blockchain, mine with cpuminer and reaper, send coins from and to old client versions,
import v03 and v06 wallet, send from encrypted wallet etc. No problems so far.

These things are uploaded daily but have no views. Who in their right mind would
search for "bitcoin today" instead of just "bitcoin".

327  Alternate cryptocurrencies / Altcoin Discussion / Re: [XRP] Falling and can't get up.. on: July 19, 2013, 03:10:20 PM

It's a "healthy correction". At 6000 XRP/BTC ripple was valued almost the same as all bitcoins including unmined ones,
this was just not reasonable.

Simple solution: Disable updates

Nooo... malware will try to fetch your wallet more vigorously than MS. (or evil government)
329  Alternate cryptocurrencies / Altcoin Discussion / Re: Hey guys, remember Tenebrix? on: July 17, 2013, 02:06:31 PM
Does anyone know if there is still a visual block explorer for Tenebrix?

not visual but works like a charm (znort's blockexplorer with a small patch for TBX/FBX):
https://github.com/wiggi/blockparser
https://github.com/wiggi/blockparser/commit/57f396533d9c35d87ea0c98a4f85e94cfed0edd3

note: the uncommented line in Makefile must go first, like this
Code:
	-DTENEBRIX              \
#        -DLITECOIN              \
#        -DFAIRBRIX              \
not this
Code:
#        -DLITECOIN              \
#        -DFAIRBRIX              \
-DTENEBRIX              \

Otherwise it will parse bitcoin. (Is this standard makefile behavior?)

330  Bitcoin / Development & Technical Discussion / Re: proposal: delete blocks older than 1000 on: July 10, 2013, 09:14:49 PM
the problem is that hoarders still have coins in very old blocks. so pruning will only work on blocks where every single transaction is 'spent'

Won't help with hoarders in very old blocks but... the one transaction that makes an entire block 'spent',
or rather the last x transactions for each block, could get incentivized.

Like, another free 27kb/block reserved only for these transactions. Easy and painless soft fork.

Or even a small negative fee. Would miners do this? (for the greater good)  Roll Eyes
331  Bitcoin / Development & Technical Discussion / Re: Building headless Bitcoin and Bitcoin-qt on Windows on: July 01, 2013, 08:51:38 PM

I'm a total noob with this code (although I do code).  Any help would be greatly appreciated.  I did look at the INSTALL file as suggested in the error message, but I still couldn't figure out what is wrong.  I loaded mingw, pearl, set the path, opened minGW and unpacked the files exactly as prescribed, but it bombs at the configure step.

Try reinstalling Mingw/Msys. (Online installer can randomly skip a component or two. The only way to notice is to inspect its log file.)

Awesome. Not sure if the "very expensive high security tamper proof hologram to secure each private key" method is practical...
333  Bitcoin / Mining speculation / Re: Bit coin difficulty by end of year, asic on: June 12, 2013, 04:44:14 PM

yeah 2 billion sounds insanely high lol

Silly me, got confused with hashrate and difficulty chart.

So, 200 million+ with current steep trend.
334  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANN] The Most Perfect Coin [UPDATED] on: June 10, 2013, 11:36:50 AM
Especially the latecomers

As OP is already in sarcasm mode, we'll likely have to wait until late 2014 when IX/I0 are finished with their subsidy.
(to have a fully minted crypto-coin in the world)

335  Bitcoin / Mining speculation / Re: Bit coin difficulty by end of year, asic on: June 10, 2013, 10:30:26 AM
if you can use trend lines on this on (as opposed to price chart Wink
more like 2,000,000,000+   (<- edit: 200,000,000 of course, not 2 billion)
(i.e. 2,000,000 GH/s)
76k May low and 124k June low are not even a month apart.
336  Bitcoin / Development & Technical Discussion / Re: Dust to dust... on: June 04, 2013, 03:43:24 PM

Dust will be all we have.

If all dust is systematically consolidated into larger coins (compared to "never mix coins
from different sources and let the dust gather dust"), would this result in more
database operations/larger blockchain files for all full clients? (more inputs/tx on average)

Blockchain would be better prunable if dust is consolidated, of course.

337  Bitcoin / Development & Technical Discussion / Re: . on: June 04, 2013, 02:45:31 PM
How much is "*lots* of RAM" in the warning for --detailed?

It likely will finish on 8GB but I wouldn't do this to my HDD,
and
Code:
./parser allBalances >allBalances.txt
(without -d) is about as memory-demanding as
Code:
./parser allBalances -a200000 -d >allBalances.txt

upgrade plan:
now:     16GB
Q1 2014: 32GB

You place buy order, get filled, then people want to dump...
How can you possibly profit from this, by selling to the guy who topped you?
340  Other / Off-topic / Re: How anonymous is TOR really? on: May 31, 2013, 04:06:52 PM
Try using Anonymouth?

Interesting concept, but to be useful it needs to catch every unusual word, all grammatical mistakes,
basically need to understand natural language.

The other, simpler way would be: force the writer to use controlled/simplified natural language,
then apply synonyms and grammar reshuffling at random.
But AFAIK such a program doesn't exist.
