Topic: [Official Support Thread] Goochain : search engine for the Bitcoin blockchain (Read 12046 times)

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.

Any particular reason off-the-shelf tools such as Coinbase's Toshi or Bitpay's Insight are not suited to your use-case? They happily allow that kind of query right away and run fine on an average computer.

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.

Scalability: still shokes on, for instance, 1NxaBCFQwejSZbQfWcYNwgqML5wWoE3rK4

I'm considering to write up a dedicated topic for that product soon.

Very cool - looks like GooChain is slowly but surely becoming a bit of a hub for determining ID-based service relationships to addresses and transactions

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.

i have just found your site. Goochain is really interesting to get blockchain data quickly.

Can you please add http://walletexplorer.com to block explorer lists?

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.


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.


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


Thanks for your valued feedback on our service!

Pretty nice update - Good to see a working FirstBits implementation again for legacy references

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.

Looks great! Keep up the good work!

Also did you make 'goochain.net' default url? I found links like 'goocha.in' are redirected to 'goochain.net'.

P.S. Maybe you can fetch input and output addresses of a transaction when we search txid. Thank you!

Today, we have finally updated our server!

- New web interface :

• New Logo
• Responsive web design
• Dedicated page for result
• Saving and social sharing of results (bookmark, print, ...)

- Full FirstBits Search :

• In the whole blockchain, all existing addresses found
  
• Real-Time

also :

• BlockTrail is now the default external link service
• Spent transactions now found when searches for an address
• Several bug fixes and improvements

Enjoy and give it a try!

Very good the_beast work, it is very easy to use and very useful. Especially for those who do not have good memory. Thanks for sharing it with us.

Not posting here doesn't mean we're off. We're still working on improving the service. 
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. 

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.


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

Except for when one of the destination addresses == the spending address, how would you know which one is the change, and which one is the payment?  I do agree that the display could be a bit more verbose, but that could easily start cluttering it up as well.

Saw you are off for many days now but the service ia still running. Is the development still ongoing? If yes, I like to see another field when searching by TXID which shows amount transacted, now it shows total output which includes chancge. As a result, we can't know how much BTC was transacted. Thank you! Hope everything is okay for you.

Thank you. I think it might have been me not using the time field that was the issue. Unfortunately it's a little difficult for what I want to use it for; searching for a specific payment. In the example above, if 95-96 went to a specific address but you don't know the amount of change, you wouldn't find it.

Are there any plans to implement a search for amount of one output within a time range?

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.

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).
