Are funds segregated?
Mt.Gox = Japan... but which bank?
Bitstamp = Slovenia... but which bank?
BTC-e = Bulgaria... etc
BTCChina = ? HK? China?
Will edit original post to update info (thanks people):
BTC-Exchange.info: Citibank (United States), Barclays Bank (United Kingdom) and Fidor Bank (Germany)

If you're going to make an altcoin here's some features you might want to think about. The most pressing ones imho are in bold.
- faster than Bitcoin
- open surface / API for decentralised exchange:
-interfaces with ripple?
-or with another cryptocurrency that doesn't exist yet? (for price stability via easier speculation)
- ^ and/or built in escrow (or multisig)
- related to the above, namecoin functionality but wider in scope than just domains
- proof of stake, quorum efficiency improvements
- prime number search or similar
- fixed small blockchain through mini-blockchain
- i2p, tor support
- merged mine compatible with another large coin for fast security startup
- no inflation built in at the start, switch to demurrage in 90 years time (next generation)
Other aspects to think about:
- programmed in something assessable, quick to dev with, i.e. python (pybt)
- could be applicable to a particular community for some reason

“Misusing paper wallets is related to that. Not all wallet software is designed to support paper wallets. People who don’t understand this have managed to delete money before, by importing a private key that was exported, making a partial payment, then destroying the wallet – not realizing that the change didn’t go back to the same key they imported.”
Yikes! Which wallet software is liable to do this? |

If you have 2 coins both with multisig capability, can that commonality be used to establish an exchange rate between the 2 different coins? Is there any high level documentation on multisig? Is there anything out there actually using it yet? Is namecoins ability to put more information in it's blockchain relevant? Is there somewhere to read about this that's a bit easier to understand?

I have a Local Exchange Trade community searching for a ledger solution.
Bitcoin is fine but goes against the goal of the system which is local. Forking a new blockchain seems over the top.
Ripple seems not ready for he prime time, since it's only running on one server. You can't change your password and we need to export the values of the preexisting database to each user.
Cyclos seems too complicated... as does OpenTransactions. We just need user, balance, send amount.
A Google Spreadsheet with forms might be fine... any example of that?

I'm on a super slow, super firewalled connection with deep packet inspection blocking ssh. I can't connect to Electrum servers for example.
What are some interesting RSS feeds to read? Is there anything else you can recommend that can be used other than IRC? Anything that can be done via email (2mb limit on attachments)

Gox rate only. No offers please. Need good rep.

So far I see NMC, DVC, groupcoin, ixcoin, i0coin will all merge mine with Bitcoin.
- Are there any more?
(and, other than NMC, is it worth it?)

I can't see the latest new threads where it used to be at the top left of the forum. Is it still there for you?

From: http://elinux.org/R-Pi_Troubleshooting#Troubleshooting_power_problemsYou can use a multimeter to compare power usage before and after you plug in your USB miner:  Results of tests:
Before tests: 4.90v available, 4.91v before polyfuse, 4.69v after polyfuse
With Eruptor: 4.54v avail, 4.91v before PF, 4.58v after
With no external power HDD: 4.90v before polyfuse, 4.46v after
Immediately after tests: 4.71v avail, 4.92v before fuse, 4.72v after and noted increased after 1min to 4.74v but after 5mins did not recover further; did not test for longer.
The HDD was noted as not fully spinning up.
Conclusions:
- a HDD needs external power no matter what. I expect if I was to test a flash drive power use is lower
- a Block Eruptor is right on the limit of what my Pi can supply. What probably happened was that it worked at first but then an increase in CPU load pushed the Polyfuse into action. This was then increased by the HDD when I tried that to test it. Now the PolyFuse has a lower limit so neither will work - I have to wait for the USB PSU to arrive before I can the Eruptor back in like I did before
- the PSU isn't supplying 5v, probably due to poor cabling
- the PolyFuse doesn't recover fully when stressed but this is no big deal
Thanks folks and in particular jbeale :-)
This has also been very useful in giving a way to measure what voltages USB devices consume. |

Goal: Make a sound when balance at an address reaches a set number of confirmations So far: #needs:
# - pulseaudio - for paplay
# - curl
# - blockexplorer not 404
address=$1
confirmations="6"
balance=$(curl --fail "http://blockexplorer.com/q/getreceivedbyaddress/$address/$confirmations") || { echo "Unable to retrieve balance" >&2; exit 1; }
while $BALANCE=0
do
sleep 1s
echo $BALANCE
done
echo $BALANCE at $ADDRESS received with $CONFIRMATIONS confirmations.
paplay /usr/share/sounds/startup3.wav
Needs a bit of tweaking. I did a search and found bash scripts in this dev section so I'm posting here... but it doesn't seem the best section to post in, sorry if it's wrong |

2 items required:
- eink display
^ display good enough to show QRcodes, eink seems most appropriate
- camera
^ this can be cheap and low quality.
The devices generates addresses and transactions, that's all. Interaction is done via the screen and camera, nothing else.
While I think the various hardware devices are great this is a lot simpler to communicate to people than USB sticks.
It would be simplest to use Android, or something that can run python and use a client that already exists.
I'd like to make such a device but it's beyond me.

I'm thinking of using https://labelectrum.herokuapp.com/ to syncronise my labels. But I don't want to synchronise wallets because I see that as a risk even if its ssyncronisetore encrypted. Are the private keys transmitted or just the labels / history? p.s. it would be nice to be able to freeze multiple receive addresses in one go by holding the shift and ctrl keys |
