Well, if you try Insight with the address you gave, it won't show anything at all. Toshi is far better, but it needs lots of disk space and a really high-end server machine.

Yes, we're aware of this issue. Any address with more than 100'000 transactions are currently not working.
Unfortunately, we haven't spent so much ressources so far to handle that issue. We are working on a new internal system that will give soon, the basic info for every single addresses. As a first step, that still won't allow searching in "heavy" addresses. Then, we have some ways to improve the rest. Anyway there are lot of corner cases which are not easy to solve.

Thanks for your support.

I think my software wasn't useful at the time of brainwallet. Now that the web service is closed, FSV seems more useful indeed.

Even if you have Electrum, FSV is much much more faster than Electrum. Also for verification, you don't need to fill every fields. Just paste in the text field the whole signature (PGP style with ----) and it will automatically extract the info. So you just need to paste and click on Verify.

If you use FSV and/or want to promote it, you can RT this Tweet :

goochain and duckduckgo also only use for single address

We have very recently added a multiple addresses query feature. We call this "paper wallet watch-only" capability.
Just enter all you adresses (up to 100), separated by commas and it will list everything and sum the amount. Then you can bookmark the result page and you'll have a one-click instant status of all the addresses provided.

Code:
1adrf1rst,1adrsec0nd,1adrth1rd

I haven't so much communicate about Goochain using this channel recently.

Just a bump up to tell you about new features:
- HD Wallet import tools (various models: Trezor, Ledger). See dedicated page
- ProofOfExistence transactions detected (when a tx is that kind, it shows a dedicated icon)
- Multi-paper wallet support: now accepts several addresses separated by comma.

Also we manage some slight graphical clean up on transactions listing.

Check out the new slide to see a quick presentation about Goochain service.

Hello, for fun purpose, I made an Ethereum address vanity generator.
I think it's the first one  Wink

Enjoy at https://github.com/antonio-fr/Vanityreum

This is now very slow, just try with 3 characters. I'm sure many of you would improve that. Also it needs further validations.

Also did you make 'goochain.net' default url? I found links like 'goocha.in' are redirected to 'goochain.net'.
Yes goochain.net is now the main and default domain name, this is mainly for SEO purpose. The 2 others are redirecting to .net domain.
Please note https for goocha.in and goochain.org could not redirect you directly as there is certificated issue and only goochain.net is valid.
But for http all redirections are working perfectly.


Maybe you can fetch input and output addresses of a transaction when we search txid. Thank you!
Well, if you search a transaction of a particular amount, inputs are not so relevant. This is like searching in a supermarket cash machine a payment of 20$ and you also want the transactions which have been paid with a 20$ bill. Goochain gives you, for now, all transactions of 20$ (on the bill) and not what was paid using a 20$ bill. A side effet is that it can also gives the transactions where the cashier gives 20$ back, as in blockchain the money back (return output) are outputs like any other outputs.
Also normally you can find the transaction "before" as the input was an output before (to continue the metaphor, the transaction where you were given a 20$ bill)
We'll consider this change after assessing impact on performance and technical details.
Still for Goochain, for a given address, it gives out inputs and outputs, as there's a link through the address.


When clicking the "Modify search" link (or going back in the browser, could fields previously used be automatically expanded?  Right now the page (/browser) remembers the last values (e.g. date range, amount range), but the fields are collapsed.
Sure, we knew about this issue. We have open a ticket internally for this matter to improve that. We think this is a major inconvenient of the user experience. We'll find a way, detecting the previous page was a search result when coming from "Modify" or dont hide if some fields are filled.
For now, we just advise to click again on "Date" and/or "Amount" in case you entered things in it. I think you already guess that Wink


Thanks for your valued feedback on our service!

Saw you are off for many days now but the service ia still running. Is the development still ongoing?
Not posting here doesn't mean we're off. We're still working on improving the service.  Wink
There are still some bugs fixing, components updates, and also we work to develop the service on business and marketing aspects. The present step is the creation of a consulting and service firm dedicated in Blockchain technology, which will manage and own officially the website.

For the greatest pleasure of all our users, in 3 to 4 weeks, we'll update our service with the following improvements:
  • New updated graphical identity, and as a starting point, a new logo will look more "professional"
  • A new dedicated page will show results, this will provide unique URL to search results
  • Social sharing buttons to give the ability to share (Facebook, Twitter, Reddit, EMail,...) or save (bookmark or print) your search results
  • FirstBits search on full Blockchain and real-time. No need to have some funds nor to wait some hours to see the address.  Cool

We're considering update the transactions list, and eventually show ProofOfService registrations.

Stay tuned on the Twitter @goochain to have the latest news and info about our service. This is the most reliable source to keep you updated.

As a result, we can't know how much BTC was transacted.
When destination addresses != the spending address, how would you know which one is the change, and which one is the payment?
Totally agree. Still, we could add a column or change "Sum Out" so that if dest=spending, it will be subtracted and only transferred amount will be displayed.


Then I can tell you about what's in the pipe and release further :
  • Provide more info in transaction list, as detecting ProofOfExistence or similar services
  • Print out block list when searching in a large time frame
  • Search text messages written in the Blockchain
  • Improving speed with optimizations and caches

15  Bitcoin / Project Development / Re: [Official Support Thread] Goochain : search engine for the Bitcoin blockchain on: March 06, 2015, 12:29:25 AM
Is it possible to search without an address, as long as the results are <4000? IE, could I search for any transaction on the blockchain between 95 and 96 bitcoins on March 5th 2015, regardless of address?

Yes, definitively. Only the first 4000 tx would be returned. This is a present limitation and this will be mitigated in the future with pages for example.

For your query you can try something like below:
Click on Date and Amount to get the full fields


For a date search, we will improve user-experience. So than when one clicks on a date, it is enough to search this kind. No need to enter time anymore.



16  Bitcoin / Project Development / Re: [Official Support Thread] Goochain : search engine for the Bitcoin blockchain on: March 06, 2015, 12:08:43 AM
shouldn't the search for first bits be case-insensitive?

I see 1GooCh gets a match but 1gooch doesn't.

I thought first bits was supposed to ignore the case.

Thanks for your feedback.

The search is case sensitive. It is just a matter of speed and good user experience: without case segregation, search would be slower and also it would give out a lot more results and take additional time to get every address details of the list. This is a trade-off between speed and usefulness, to stay really user-friendly. Also in everyday life, WORD is equivalent to word but in blockchain world 1goochainblaba is not the same address as 1GOOCHAINblabla.
We are actually working on a new firstbit internal engine that would be real-time, lower the amount limit, and ultimately work with any address in the blockchain. We are also working on a backend replacement so that it would be quicker to get address details. Depending on all our progress and results we would implement case-insensitive search for FirstBit feature.

Please additionally note, these days the real amount limit required is more at 0.04 than 0.02 btc announced (we haven't yet updated our description pages).

It's indeed working now. Are you pulling that information from the blockchain.info API?
Not at all, we're 100 % independent. We run a full node dedicated for our server. Any others API providers or explorers can go offline, Goochain would be always up.
We also have developed our own BIP32/44 libraries to handle xpub searches and give out addresses list.

Quote
I'm looking for alternative (and maybe open source) blockchain explorers which fully support HD wallet lookup by xpub keys
First of all, Goochain is not a real block-explorer but a search engine. It gives you basic info and provides links to explorers. It can be seen as a "meta-explorer". Still, Goochain service can be very handy for quick basic check, as HD wallet amount for the current example. Goochain is light-weight and ad-free.
To be fair, I didn't even know BlockChain was providing this xpub feature. This is not documented at all from their side. I don't know any other website that provides this feature. I think some APIs service can have this feature (REST).
