[Official Support Thread] Goochain : search engine for the Bitcoin blockchain

[the_beast]

Introducing Goochain, the first search engine for the Bitcoin blockchain.
It brings new unrivaled features in the Bitcoin web service space.



goochain.net




Provides links from various inputs: search field can be hash, address, time and/or amount.
Can retrieve transactions from blockchain in a pioneering new way, all in real-time.
Gives basic info and print out links to have further info.


More specifically:

• From address "base58chk",  hash160 : gives basic info
• From an adress list (comma separated): gives balance and sum
  
• From starting characters (firstbits) of an address : find matching full addresses
• From HD Wallet extended public key (xpub BIP32) : lists all used addresses and balance
• From block hash or index : gives basic info
• From address and time frame : lists all matching transactions
• From address and a given amount  : lists all matching transactions
• From block and a given amount  : lists all matching transactions
• From a transaction ID : gives basic info
• From a given amount and a time frame (blank search) : lists all matching transactions in the blockchain

For all results, a link is provided to get full info.
"Given amount" can be equal or min/max. "time-frame" can be a time windows or a date (day).
Timeframe and amount range search can be used concurrently for a given address.


Check out a slide presentation Here !


When the found items are transactions, a list is displayed and can be sorted by date or amount.

This is not a full info site, but a search engine for the blockchain. It gives links to external sites, then you can find all info on these sites. Info given are basic, but you have further info when following links. External service (links) is selectable, and automatically saved after each search.

Everything is done on the server: no external API, Bitcoin node running locally.


Use cases:

• You want to quickly check the amount of an address
• Check the amount in your Trezor wallet (from xpub code provided)
• You have a paper/cold wallet : just type the 5 or 6 starting characters of the public address
• You know by heart the beginning of a Bitcoin address ("vanity" generated)
• You can list all transactions made during a month with your address
• Search "spam" transactions of a given address (min=0, max=0.01)
• You just remember the day of a particular transaction with your address
• You want to filter transactions related to a service bought (by amount and/or date)
• Can help during dispute or investigation with searching a transaction of an known amount in the blockchain during a time-frame.
  

Now detects and displays ProofOfExistence blockchain notary service.

Is it really like Google? If it is free, users are the products, I must be tracked down?
No, this is free because it is ran by enthusiastic people in Bitcoin. Running the service doesn't cost so much money for now.
No identification cookie, no ad, no external and intrusive tracker. The only thing it does is searching your requests and printing out back the result. HTTPS is enabled and default so no info is shared on the Internet and requests are anonymous and private.

If you like the service and/or want to support the service, you can give a tip to this address:

(address changed for multisig)


Known Limitations

• Print out only 4000 transactions in case too many results
• Print out only 100 addresses in case too many matching
• 24h searching range when data and amount through full blockchain
• Provides transaction by Sum of TxOUT (also fee)

Known issues

• Some searches can be too long and it indefinitely prints out "Searching Please Wait"

Future improvements/functionalities

• Provide more info and sorting options in transaction list
• Improve amount range and date input
• Search by address amount (on most valuable address)
• Graph of address amount vs time
• Print out block list when searching in a time frame
• Search a message written in blockchain (OP_RETURN or "unspendable scriptPubKeys")
• Amount would be USD also

Really awesome stuff! Good job! 

Will be using for sure.

Anti-spam feature sounds great

By the way, thanks for the first tip.

Not a single tip to GooChain address will be cash out before Jan 1st 2015.

[Miitch]

What a great project! I've bookmarked it too

[bitgrimster]

The name sounds good. Goochain, i like that name.

Your project will be a good success for sure.

[the_beast]

GooChain can now accept input from RIPEMD160 hash for addresses.

Would be great if you add the possibility to search for texts/data within the blockchain

Yes, this is what I mean when writing as a future improvement:

Search a text wrote in blockchain "message"

As every other feature, I have to assess if this would not use so much resources (request answer from server in an "acceptable" time).

[Muhammed Zakir]

I don't know why but my balance is incorrect. I tried 3 explorers, the explorers shows correct balance but Goochain is showing more than that, though there is no problem with no. of transactions. My address is 1MzakiRDem5MCocbcP7DgfcVGZNZe2KqaC . Please check it!

[the_beast]

Thanks for reporting that. I've already noticed some differences with cumulative in/output on an address.
I though it was because of managing "transacted", but issues can be linked. Insight is reporting same amount as GooChain.
Can you share transactions list and amount from your client ?

[the_beast]

I will perform some major changes on some main blocks of the system, service will be disrupted. It might last some hours.
It won't fix this issue, but that would help for my investigation.

[the_beast]

Fortunately, I managed to fix this issue. But I had to reindex all database, hence the long disruption (on top of overnight, I need sleep)

Goochain is now back on line.

Goochain is now back on line. 

I can't access it. Any problem? It seems Goochain(1,2&3) are down.

[the_beast]

No problem from my side, server ok, acces from multiple ip/fai ok. Please double check from your side.

[the_beast]

New feature: find full address from starting characters.

Gives results if beginning given is unique among addresses that have more than 0.02 BTC.

"1Good" , "1BETaJU", "1BTCs", "1GooCh",...

[the_beast]

In the following days, I will improve search from beginning of address : it will list all matching addresses, as a real search engine.   

[the_beast]

New unrivalled feature : One can search now with starting sequence of an address (at least 4 chars) and it lists all matching addresses (balance > 0.02 BTC).

GooChain is one step closer to be the ultimate BTC search engine.  

[Miitch]

I like it! Big project by the looks of it

[Boussac]

Tested ok with a funded address but failed with firstbits.
Very interesting service anyway although any blockexplor could possibly offer the same.
The search algorithm can make a difference but It's not obvious to me at this point.

Thanks for trying out!

The difference is more about searching options that are advanced. For example one can search all transactions during a time-frame with his own address.

Can you give more details about your personal issue on firstbits? Normally, every addresses with more 0.02 BTC and not HD are listed. "Disposable" addresses as in HD wallet may be found but no guarantee.
Also this requires at least 4 chars, including "1". "1Bat", "1abc", "1Goo" would work like "1star", "1Bitcoin", and so on...

I will update main post to reflect that.

[Boussac]

My bad, I just realized that the address I tried for the firstbits test had been emptied out.
Firstbits work indeed perfectly on goochain with funded addresses.
