Hi all,

Just for the record - I am still me, and have just updated my password for security reasons. (migration of password management system)
I have also changed my email to a more secure email which is already associated with my profile. Will update this with a signed message from my GPG key in a bit.

PS: Nope, I'll never sell my account or do anything like that for the record.

6  Bitcoin / Hardware wallets / How much would you trust trezor? on: November 21, 2015, 09:05:31 PM
Just something I've been thinking lately - I hold a sizeable sum in a trezor that I bought lately (after I did some review of the code and the protocols used), but I'm wondering about how much others would trust a trezor personally. I used to use Offline Armory exclusively but it's taking a toll on my SSD's by running a full client on my online computer.
7  Bitcoin / Development & Technical Discussion / Running bitcoind in pruning mode on: November 04, 2015, 06:09:33 AM
Hi all,

I'm trying to run a bitcoin node (satoshi 0.11) in pruning mode. If I want to keep the blockchain size at 30gb, should I just restart bitcoind with the command 'bitcoind -prune=30000' ?

8  Bitcoin / Hardware / [Review 3] A Spondolies SP20 review on: December 16, 2014, 11:09:37 PM
Disclosure: Spondolies Tech was very kind to send me a SP20 miner as per their Legendary Review review thread here:

The obligatory background story: I'm a long-time bitcoin user since 2011. I first came across bitcoin and CPU-mined a block around 2010, but sadly I did not back the drive up. I've been a part time miner since then, starting up with GPU's and slowly upgrading to FPGA's and an Avalon. I have stopped mining for over a year due to my relocation and being generally super busy with everything else.

The review:

The miner was shipped extremely fast via Fedex from Israel to US. In total, it took 3 days including a Friday, Saturday and Sunday. It was at the door early morning on Monday.  Grin

The package was extremely well thought out and designed, and I could not feel any give in even after trying to sit on it.

Shown is the paper box housing it came in:

Setting up:

I bought two CX750 PSU's in anticipation of the miner. Setting up was straightforward - a paper clip was inserted in the green wire and a black wire respectively. (shoutout to Dogie for his extremely concise website here: Two cables of each PSU were connected to the miner, and powering up was effortless.

PSU's that I used:

The actual setting up took much more time on my part as I was trying to get it to connect to a large workspace network. For regular users with a limited number of devices on their network, opening on any browser would work instantaneously. With the help of Spondolies-Tech (Guy), wh00per and the others, I managed to get it online.

Procedures for situation like this:

1 ) Get wireshark installed in your computer.
2 ) Connect the miner directly via ethernet cable to the computer.
3 ) Set up monitoring on the ethernet port using wireshark.
4 ) You'll get the DHCP requests from the miner unit as it tries to go online.
5 ) Write down the MAC address.
6 ) Whitelist the MAC address on your network.
7 ) Connect the miner directly to the network.
8 ) Using AngryIP scanner, try to determine the actual IP of the device. (I skipped this as I have access to the admin page showing the IP of the miner)
9 ) Fire up a browser while on the same network and go to http://(the ip address).
10 ) If it works, you'll be presented with a login screen. (user/pass:admin)

The mining:

It is really straightforward after you manage to connect to it. Just input your pool settings and you're good to go.

The miner stats after some time:

ASIC Stats:

The noise level is quite high - the decibel tool on my phone gives me around 80dB.

After running continuously for almost 24 hours, I'm happy to say that everything went well, although initially I had a few crashes (complete crash needing a power cycle) that I suspect was due to high temperatures in the box killing the control unit. I've since placed it somewhere cold, and it has been mining happily since.

Update: It's been running continuously for almost two days straight. No reboots/power cycle was required. It's been a dream.


PS: I'll add stuff to this as I keep on playing with it.

Hey guys,

Sorry for my (yet again) unannounced hiatus for the past month or so - I have been extremely busy due to heavy travelling and am just back to Malaysia from China. I am alive,
although not really well and extremely apologetic for what my delay have done. I've released a few escrows I've been holding in the order of magnitude and those I can
clear within this hour.

bitcointalk forum coins (of 1000 BTC)

I'll clear the raffle coins once I figure out who won as I didn't receive a PM regarding this yet, but be rest assured that I'll clear this ASAP.

I'll be back to clear everything else once I get back to the States again - I'm catching another intercontinental flight in roughly 12 hours which should last around 25 hours including
 layovers, and hopefully I'll use the jet lag when I reach there to clear the remaining urgent escrows.

John K.,

Please sent the 1000 bitcoins you are holding for the forum to the following address controlled by me:

This is an official order. Your treasurer agreement requires that you execute this transaction within 14 days (except in certain special cases which I do not believe apply here).

Thank you.

Hey guys,

I'm looking to sell about 30-50 BTC for a Bank of America cash deposit. Please drop me a PM ASAP if you're interested, as it should be gone fast. I'm looking for about 6% more than bitstamp, or roughly 135 USD per BTC. I can and will provide a signed contract with my key as always when we have a deal finalized.

Hey guys,

I'm interesting in selling about 30-50 BTC, depending on the rate etc for a BOFA cash deposit. I go with Gox rates, but please PM me to confirm beforehand.

13  Economy / Currency exchange / [WTS] BTC for MoneyGram/ (other international money transfers) on: August 02, 2013, 12:33:25 AM
Hey guys,

I'm looking to sell around 10-50 BTC for MoneyGram/Western Union/Malaysian Bank transfer or Cash deposit for 105 USD(subject to change if market moves too much) each, and you pay the transfer fees. I'm at Malaysia right now so unfortunately most sending options are not available for me.

Just drop me a PM if you have anything to ask - I don't bite.  Wink


PS: Of course, you send first but I'll issue a signed contract as always.  Smiley

It should be a good idea to make a list of Bitcoin-accepting VPN's too as I see Bitcoin is very popular in the VPN industry.
16  Other / Off-topic / Best VPN's using Bitcoin? on: July 01, 2013, 01:44:59 AM
Hey all,

With the recent NSA antics, I'm finally convinced myself to get a VPN before it's too late.  Wink I've looked at a couple of VPN's like PIA (the one sponsoring the forums) and AirVPN, but I'm still undecided. Is there any suggestions you guys can give me here?

- Payable with Bitcoins
- FAST speeds, low pings
- Reliable
- No logging
- Multidevices possible, e.g.: I want to connect my phone and laptop at once.

- Many servers to choose from
- Asian servers (Singapore/Hong Kong?)
- Price isn't too crazy (But I'm prepared to pay an upwards of $60+ a year if you can convince me it's worth it)

Thanks guys!  Grin
17  Local / 挖矿 / Avalon芯片团购转让程序 on: June 13, 2013, 03:57:50 PM
请转让芯片的各位买家和卖家注意: 因为团购的芯片已经启动了收获统计以及授权收货程序,在转让交易中,请务必先确认卖家的芯片是否已经登记收货信息或者授权他人收货。


我想了想,还是用szmarco 所建议的方针(再加上修改) - 一来方便,二来不容易出错。


0 ,买家卖家决定一个价格;

请注意,我们只允许你转让所有你购买的芯片,不可以分开销售。这个转让许可将随时停止,因为当芯片准备发货时,可能更多的活跃转让交易使得我们难以及时处理,我们不能继续允许转让,我们有权随时终止该项服务。目前,我们并不收转让交易手续费,但是如果这个转让服务太过浪费时间, 这可能会改变。

PS: 别忘记,Avalon发货时通常喜欢一起寄货,所以在后面的团购并不代表你会比前面的团购 晚 拿到芯片。  Wink

(updated, thanks again Jimmy!)

Another sold/hacked account probably. Was faking my escrow contracts.  Undecided

Hash: SHA1

The escrow address for DPony13 (the seller) and erikspoon (the buyer) transaction would be:

1KAG7p4jkJrHSeMgW6FjJWzPye1iRKqj6g - Bitcoin

Please state and agree to the conditions (It is 8000 XRP for 1.33 BTC) beforehand.

If possible, GPG sign your agreement to prevent any discrepancies later on and please ship with tracking to prevent problems during delivery. GPG signing is not a requirement, and any verbal exchange in the form of private messages or posts on, or email is effective as a ‘statement of condition’.

The fine print:
This Contract is solely generated for the purpose of facilitating the transaction between the seller and the buyer, which refers to the pseudonyms used on
The escrow holder, John, assumes and gives no liability or guarantees on the satisfaction of all parties involved, although he agrees to mediate and facilitate the deal to the fullest extent he is capable of.  On the event that any problems arises, he will release the escrow to whichever party that presents him with the most convincing proof and/or after an open discussion with others or theymos.
The verbal acceptance by both parties (or the failure to reject) and the sending of Bitcoins to the escrow address above constitutes the acceptance of the terms and conditions stated, and the activation of this Contract.

Please understand that I am assuming the risk of holding the escrowed Bitcoins, and I am using my own time to facilitate this transaction. 
If possible, please tip me at 1NB1KFnFqnP3WSDZQrWV3pfmph5fWRyadz .

Thank you.

19  Economy / Scam Accusations / Possible phishing link! on: June 01, 2013, 07:35:32 AM
Someone reported the thread below - the author was spamming this in a few places. From what I see, is a phishing site. Please do your own diligence before downloading any binaries.


Bitcoin-Qt/bitcoind version 0.8.2 is now available from:

This is a maintenance release that fixes many bugs and includes
a few small new features.

Please report bugs using the issue tracker at github:

How to Upgrade

If you are running an older version, shut it down. Wait
until it has completely shut down (which might take a few minutes for older
versions), then run the installer (on Windows) or just copy over
/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

If you are upgrading from version 0.7.2 or earlier, the first time you
run 0.8.2 your blockchain files will be re-indexed, which will take
anywhere from 30 minutes to several hours, depending on the speed of
your machine.

0.8.2 Release notes

Fee Policy changes

The default fee for low-priority transactions is lowered from 0.0005 BTC
(for each 1,000 bytes in the transaction; an average transaction is
about 500 bytes) to 0.0001 BTC.

Payments (transaction outputs) of 0.543 times the minimum relay fee
(0.00005430 BTC) are now considered 'non-standard', because storing them
costs the network more than they are worth and spending them will usually
cost their owner more in transaction fees than they are worth.

Non-standard transactions are not relayed across the network, are not included
in blocks by most miners, and will not show up in your wallet until they are
included in a block.

The default fee policy can be overridden using the -mintxfee and -minrelaytxfee
command-line options, but note that we intend to replace the hard-coded fees
with code that automatically calculates and suggests appropriate fees in the
0.9 release and note that if you set a fee policy significantly different from
the rest of the network your transactions may never confirm.

Bitcoin-Qt changes

* New icon and splash screen
* Improve reporting of synchronization process
* Remove hardcoded fee recommendations
* Improve metadata of executable on MacOSX and Windows
* Move export button to individual tabs instead of toolbar
* Add "send coins" command to context menu in address book
* Add "copy txid" command to copy transaction IDs from transaction overview
* Save & restore window size and position when showing & hiding window
* New translations: Arabic (ar), Bosnian (bs), Catalan (ca), Welsh (cy),
  Esperanto (eo), Interlingua (la), Latvian (lv) and many improvements
  to current translations

* OSX support for click-to-pay (bitcoin:) links
* Fix GUI disappearing problem on MacOSX (issue #1522)

* Copy addresses to middle-mouse-button clipboard

Command-line options

* -walletnotify will call a command on receiving transactions that affect the wallet.
* -alertnotify will call a command on receiving an alert from the network.
* -par now takes a negative number, to leave a certain amount of cores free.

JSON-RPC API changes

* listunspent now lists account and address infromation.
* getinfo now also returns the time adjustment estimated from your peers.
* getpeerinfo now returns bytessent, bytesrecv and syncnode.
* gettxoutsetinfo returns statistics about the unspent transaction output database.
* gettxout returns information about a specific unspent transaction output.

Networking changes

* Significant changes to the networking code, reducing latency and memory consumption.
* Avoid initial block download stalling.
* Remove IRC seeding support.
* Performance tweaks.
* Added testnet DNS seeds.

Wallet compatibility/rescuing

* Cases where wallets cannot be opened in another version/installation should be reduced.
* -salvagewallet now works for encrypted wallets.

Thanks to everybody who contributed to the 0.8.2 release!
