This is probably some small group within them. A subsidiary. I'm not getting excited.

I do some more research.

This was a service of another company started at Dec 2011, and Baidu acquired the company just on 2 Sept 2013. So yes, this is definitely an attempt to advertise the service. But any publicity is good publicity. This news has started circulating in all Chinese news sites.

Baidu Jasule Accepts Bitcoin Payment

15 October 2013

How could we reflect the characteristics of a trendy IT person and a professional webmaster? The answer of course is to own bitcoin! ! !

Bitcoin as an emerging electronic money has already had a large degree of recognition in the world, deep into the daily life. It can be used to buy a cup of coffee, and also be directly converted into real money. In China, bitcoin is still a "fashionable" thing. Today, I have a good news for everyone: from 14 October 2013 onwards, Baidu Jashule officially support bitcoin payment. Baidu Jashule users can use bitcoin to pay for any Jashule services. Baidu Jashule as the innovator of the Internet, has become the first cloud services vendor to support bitcoin, giving us a richer payment methods and experience.

In the future, Baidu Jashule will continue to make more new attempts to bring you more convenient payment methods!

Thanks for the translation, what is Baidu Jashule?

Baidu Jiasule is a CloudFlare-like speed-up and anti-DDOS service for websites. You can google "CloudFlare" to learn it more.

Why do they have a bitcoin address in the press release?

It is their payment address.

It seems the bitcoin payment is not automated. User have to inform the administrator before they pay and it will be processed manually.

lol, the "innovator of the internet".

Frankly speaking, in many ways Baidu is a copy-cat, just like most Chinese enterprise. However, accepting bitcoin should still be considered as an innovation for this level of players

Really?? This seems very half-hearted.

That's reasonable as they are not sure how many users will really pay in bitcoin and that's risky in investing a new payment system. There is no bitpay-equivalent in China. Also, their real intention may just be using this opportunity to advertise their service.

Wow, that's Alexa #5, so this is the busiest website accepting bitcoin (although this is only one of its many services. Still a good start)
1968  Bitcoin / Bitcoin Discussion / Re: Breaking news: Baidu (NASDAQ:BIDU) accepts BITCOIN! on: October 15, 2013, 11:26:37 AM
This is nice but I'll wait for a confirmation.

You may not know Chinese, but I can tell you the link is already the official press release.
1969  Bitcoin / Bitcoin Discussion / Re: Breaking news: Baidu (NASDAQ:BIDU) accepts BITCOIN! on: October 15, 2013, 11:25:22 AM
Get ready for launch!

This actually may be related to yesterday's China-led rally. The announcement (published on 15 Oct) mentions that they start accept bitcoin on 14 Oct. There could be insider trading.

Anyway, this is a good news as I think this is the biggest Chinese company accepting bitcoin

Announcement in Chinese: http://jiasule.baidu.com/news/525cd5aabf9efd699f800e7e/

Baidu Jiasule, a CloudFlare-like anti-DDOS service by Baidu (NASDAQ:BIDU), today announce that they accept bitcoin for payment. This is the first service of this kind accepts bitcoin (in the whole world, not just China).

If you don't know what is Baidu: it is the Google of China.

Trading 72,000BTC in 24 hours with only 2% price movement (855-875)? Really don't understand why people are so obsessed with such blatant fake volume.
1972  Bitcoin / Bitcoin Discussion / Re: Silk Road: Trail of 11,329.89BTC on: October 14, 2013, 04:37:39 PM
bitcoinfog.com is the only deepnet service for this purpose (at least to my knowledge). maybe he used them, if he didn't mix it himself

This was not even existed in 2011
1973  Economy / Speculation / Re: Wall Observer - China wall movement tracker on: October 14, 2013, 04:06:42 PM
You almost wonder, if they have the BTC to back the volume or if all this is trading on paper.

Why not? Most ASIC were produced in China

And the correlation between China producing ASIC chips and having a fully funded exchange.... ??

Not sure what you mean but deposit and withdraw requests for both fiat and BTC are timely processed. So they are not trading on paper or having fractional reserve.
1974  Bitcoin / Bitcoin Discussion / Re: Silk Road: Trail of 11,329.89BTC on: October 14, 2013, 04:02:57 PM

Notice that all the inputs came from this address: 15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y. I'm pretty sure if you go backwards you can land at DPR's other accounts.

Also, I don't think DPR just spent it (to someone elses address) as the trail has only addresses that were used for mixing... all the intermediate addresses have exactly 2 transactions... 1 receive from previous mixing address and 1 to the next mixing address all the way to its destination 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a.

The script I wrote followed a path that had addresses with only 2-10 transactions.
So lets break in down:

DPR's known address: 1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS
Tumbler's receive address: 1BG9jDV3pA1MsJUnvRyWuA2b7PfGd4MZaw (only 2 transactions)
Tumbler's next mixer address: 12h6TzwPNBvDnppbsqpyXwW4oo5UUKaKSa (only 2 transactions)
Tumbler's next mixer address: 1EG9HJG9aGqzgGujfNQMiNbyqpKnFxafvE (4 transactions but note that the only output is to 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh... the remaining transactions are just too small -> this address may have been reused by the tumbler)
Tumbler's next mixer address: 1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh (only 2 transactions)
Tumbler's final mixer address: 15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y (7 transactions -> Note that this has only one output)
Final Destination address: 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a

There is no other path followed by the tumbler. So possibly the service used by DPR was pretty weak or probably he just manually mixed it himself.


The 1LDNL....... received 11,329.89 BTC, while only 2,000 BTC end up in 1933phf..... Not saying you are wrong but that's not strong enough.

Is there any other known addresses of DPR?
1975  Bitcoin / Bitcoin Discussion / Re: Silk Road: Trail of 11,329.89BTC on: October 14, 2013, 03:31:32 PM
So, I have been playing around with Neo4j lately and was wanting to experiment using a large dataset. The blockchain struck me as the best dataset for performing analysis. I was always intrigued by this address specifically : 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a which has around 111114.60025818 BTC with nothing spent. From the recent disclosures on Silk Road and about DPR having safely locked up 600000 BTC into an encrypted offline wallet, I was hoping to find some connect between this address and the address he unwittingly leaked out 1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS in this post: https://bitcointalk.org/index.php?topic=6460.msg94424#msg94424

Long story short, I think, if my analysis is not wrong, the address 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a belongs to DPR. He used a tumbler to mix his coins but looks like it wasn't good enough to hide the trail. I just used a shortest path algo to find the path that leads to the final destination. So here is the trail:

1LDNLreKJ6GawBHPgB5yfVLBERi8g3SbQS (tx: afeecd8e47d6c3912d6c2e5f7a2ceafdecc9d4ad221480fe90847c23f81c8892) ->
1BG9jDV3pA1MsJUnvRyWuA2b7PfGd4MZaw (tx: acb4608da3e06bb787682c7b2f5c4808b831301617cdf5986fd2693970c8040e) ->
12h6TzwPNBvDnppbsqpyXwW4oo5UUKaKSa (tx: fb059f1acfe0399ca2d5090ff9264dfe88b918230c01f09391eaefa83082f4fb) ->
1EG9HJG9aGqzgGujfNQMiNbyqpKnFxafvE (tx: f3b6040fd5c2f70d4be82e5a97b9fcad67a1ebdfa20af8c7915b82afdd8aa174) ->
1AHki5AbZYiz4fHkGSTVKN3T1Tv5PwZpnh (tx: 758b776dec1851a94a6c4ee1782aaf7210a59ae1e8c184d2b469d8039ff1773c) ->
15TEAwEMxVS3BK718HhwgJg7nxwyJ2ib9y (tx: 70d46f768b73e50440e41977eb13ab25826137a8d34486958c7d55c5931c6081) ->
1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a

What do you guys think?


I found the same link too. The 1933ph..... could be DPR's address but I think the evidence is not strong enough. It's possible that he just spent 2000BTC with the tx afeecd8e47d6c3912d6c2e5f7a2ceafdecc9d4ad221480fe90847c23f81c8892.

BTW, someone sent 2 x 1.73632986BTC to 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a on 2013-10-09.

Don't mine testnet coins just for fun! You will disrupt the testnet. Testnet coins are completely worthless and the devs could restart the testnet any time.

不要亂挖testnet bitcoin. Testnet bitcoin一文不值, 而且bitcoin開發人員有權隨時重設testnet.

When did btcchina start this "0% trade fee" promotion everyone is touting?

End of September I suppose. This is a response to many new exchanges with zero fee.

Isn't 888 a lucky number in China?  Grin

no, it's 8888.

Does 8888 really have special significance over other 8-based numbers? Wikipedia indicates that pretty much anything with 8's is good:

http://en.wikipedia.org/wiki/Numbers_in_Chinese_culture#Eight

ok, let me be a bit more clear:  no, it's 8888  Tongue

That's not more clear! Please elaborate!

More 8s is better, of course. And they don't like 4 and 7, as they are related the death

Using merklized key, a Lamport public key could be reused (for limited times) https://en.wikipedia.org/wiki/Lamport_signature#Public_key_for_multiple_messages

Using CHECKSIG 2.0 I proposed at https://bitcointalk.org/index.php?topic=258931.0 , we can use one signature for many inputs from the same "address"
