HW/A is stable at 0.9% after 3 days without heatsink.
How is it going for you?

I actually think the out-of-the-box heatsink makes it worse, we'll see in the "long" run.
It is not increasing the surface, I told friedcat; his reply was: "It' won't trap the heat since the surface between aluminum and air is still more effective in transferring heat than the surface between the non-metal PCB backside and air. Especially when there are any airflow."
Maybe he's right, but I like silence.
What this needs is a proper top mounted heatsink, like an inverse pyramid from the BE 100 chip!

These chips are fun but they won't last, really poor heat design.
My HW is slowly creeping up, 0,85%... I give it one month.
0.85% = HW:96 / A:11323 is that the right calculation (bfgminer)?

My HW is down to 0.8% without heatsink or fan after one day.
How is it going for you heatsink and active cooling guys?

bitcoinbankbook.com (bbb)
It's a fully functional bitcoin client; just sign up, add an address and transfer a small amount of btc to it.
This way your bitcoins are always accessible at any time without hassle.
----
I built this for 2 reasons: customizable security and instant access from anywhere, which I need as the blockchain grows since I don't have time, cpu, memory or diskspace to run the satoshi client on anything else than a dedicated server.
This works on all devices: phones, consoles, computers; anything with a browser.
----
We don't rely on HTTPS for security:
BBB is only as secure as you password! Use an appropriate pass according to the amount stored.
The only vulnerability that HTTPS and bbb have is MITM, so ask yourself; if you're the MITM would you masquerade HTTPS and see all traffic or reverse engineer some heavily obfuscated GWT code, for one site only?
For accounts with large wallets I provide an archive of the client files so you can run bbb from your local harddrive.
> chrome --disable-web-security book.html
SHA of the archive (2015/06/02):
728a81dd1eedb529ead056c3c9a0636dd3011944
----
The way we secure our protocol:
When you register we send a mail with a client side encryption key.
We then hash & encrypt your pass before it leaves your browser with javascript SHA and AES implementations.
When you login we simply SHA your pass twice, the second time with a random salt.
Finally payments are AES encrypted with 'random salt pass' SHA as encryption key.
BTW, if you wan't to pay someone that has a bbb account, use their mail as address in the pay dialog to avoid hitting the blockchain.
----
BUGS:
server-sent events don't work on registration.
account balance does not update on realtime transaction.
TODO:
server-sent events.
polling price from bitstamp.
bitcoind errors feedback.
add oil and gold prices.
realtime incoming transaction update.
merchant HTTP billing API.
lock unspent outputs to "improve" anonymity.
AES encrypt everything.
2 phase commit escrow.
private keys backup.
after email / before password greeting. (this way hackers need to steal the database to phish you)
----
If you would like to host your own; I sell two licences for this software:
- single-user (req. bitcoind, java). 50$
- multi-user (req. bitcoind, java, mysql). 100$/year
It uses GWT.
I will extend the product with any feature a paying customer has in mind in "valve time". If you are a multi-user customer, and need a feature quickly, it's 100$/hour.

HW with your new heat-sink?
Just ordered, what HW are you guys with proper cooling having? 0%? |
|
|
|
I get 1% HW too, without heatsink. Top mounted 8x8mm heatsink with real paste is the solution!   |
|
|
|
|
So how hot do these get? Any chance at running them without fan?
|
|
|
|
|
Yea, I'm going to use one account per user (so that you can transfer coins internally without hitting the blockchain) and then I'll do a separate database label system for both addresses and transactions so people can tag their stuff.

How can you trace this if they go through a mixer?
you can't. You can always trace everything. The question is "will anyone trace anything at any point in the future". If someone builds a "tracer"; meaning software that reverse indexes the blockchain so you immediately can get an answer to the question "was any of the coins I just received reported stolen by anyone at any point in the whole history of bitcoin" then immediately all stolen bitcoins become "worth less". What are the odds that this will happen when bitcoin grows? I would say 100%. There's nothing like the smell of a fresh block of coins! "you cannot steal bitcoins" -rupy You will notice that the ones commenting negatively about this effort bought coins (without sourcing them); while the positive ones, mined theirs. It's greed against honor. I can also promise you that big investors already do this, you don't buy the pig in the bag.Thanks! |

It seems labels are deprecated? Why? I would like to associate addresses with both accounts and labels! account -+- address --- label
|
+- address --- label
So I guess the way to do this is to create an address either by label or account and then associate the address with the other. getnewaddress
setaccount
OR
getaccountaddress
setlabel

I wonder why they are sent in 3! parcels?
|
|
|

Ok ok will insert an additional column.
Perhaps with the initials and last digit of zip code.
So you can check yourself
Or too much personal information?
What's wrong with yes/no? |

There is no free hosting for these afaik, and the linux on RPi is stable because the community is huge.
And as I said, I now run the bitcoind on another server, so I already solved this problem.
I will use battery backup and RUT-500 redundant 3G to handle fiber/power failures for uptime at home.

You can't go professional running anything on a Raspberry Pi. It's not designed as a professional piece of equipment.
I'm building a PaaS on a cluster of RPi's, so I obviously think you are wrong here. I'm going to modify one of these, I mean why risk it?  |
|

Ok, we'll see, looking forward to it!
I removed the posts in your threads because I'm going to cleanup my "Show new replies to your posts." thing.
|
|

|

Yeah, but you can't run anything professional with a bitcoind that is restarted every hour.
I think the bitcoin community really needs to move out of the garage; if we're ever going to get this thing going.

No I meant with bitcoind, it runs out of memory after 4-5 hours... no matter what you do.
I got a pi up and running as a bitcoind node just to try it out once, and it was working with the old leveldb and only 256 MB memory. Ok, but I need it to run 24/7 stable... |
