Bitcoin Forum

LAST Edit: 10/03/2017 after a complete rewrite of the gui and the addition of many new functions!

Presenting my website, filled with, what i hope are usefull bitcoin tools for everybody not running a full node and/or lacking the time or knowledge to get the most out of their BTC .The tools are suited for most standard transactions, but some also work for other tx's:


Currently implemented:

• a tool to check if your transaction is not getting confirmed because you didn't add enough fees
  
  • including a wizard to create a CPFP for a stuck transaction
  • including a wizard to create a RBF for a stuck transaction
  • including a basic tutorial on how to get a stuck transaction confirmed
  • shortlink http://www.mocacinno.com/feecheck.php?tx=[txid]
• a tool to get your raw, signed transaction from my mempool
  
  • i keep transactions in my mempool for 10 days instead of 3, and my mempool can grow up to 600 Mb instead of 150
  • shortlink http://www.mocacinno.com/getraw.php?txid=[txid]
• a tool to decode any raw transaction and shows it in a simple json format
• a tool to create raw, unsigned transactions based on unspent input tx's, n's, addresses and vouts (high difficulty level)
• a tool to push a raw, signed transaction to my node
• a tool to estimate which fee you should add to your transaction BEFORE you create it, so it has less chance of getting stuck
  
  • or - based on the size you estimated
  • or - based on the number of inputs and outputs
  • or - based on a comma seperated address list and a transferred value
• a tool to validate signed messages
• a tool to check if an address is valid
• a tool to timestamp any message you'd like
• a list of usefull links

Todo list:

• Members area where you can set an alert once your transaction confirms
• Members area where you can set enter tx's which i need to re-broadcast untill they confirm
• Price ticker
• loads more tutorials and how-to's
• decission trees on which wallet to pick
• decission trees on how to unstick your transaction
• layout rework (not all tools shown on a single page)
• using mod_rewrite for nicer urls
• captcha's on resource intensive pages, including the page where i use the blockr.io api
• a contact form
• rewriting the TOS

I tested the site and it recommends 120 satoshis/byte but 100 satoshis are fine as per https://bitcoinfees.21.co/.

It would be better if you could add some videos on how to double spend and explain CPFP process. Here is one video that I found useful: https://www.youtube.com/watch?v=ycq7O48aPvQ

Great one but I think there are already some explorers like : live.blockexplorer.com showing mining preference (which is a very cool stuff) and also recently I think blockchain also updated their explorer as it is now also showing fee/byte. It would be great if you can bring mining preference and confidence concept from live.blockexplorer.com into your site.

Also notification ringer when a bitcoin transaction gets confirmed and also maybe like link to transaction accelerator service would be cool.

Thanks for the input, i'll try to add some links to tutorials to the next version.
About the 100 satoshi's/byte => https://bitcoinfees.21.co/api/v1/fees/recommended still recommands 120 satoshi's/byte for a 90% chance of getting into the next 3 blocks, and 100 satoshi's/byte for a 90% chance of getting in the next 6 blocks.
I could probably show both... but 120 appears to be necessary for the fasted confirmation time at this moment.


Thanks for the feedback, to bad, but live.blockexplorer.com seems to be down at the moment, so i cannot check it out.
About the notification ringer: would it be best to change the browser's tab title, or do you mean sending an email or something?
BTW: the link to viabtc is already there, but i'll make it a bit clearer in the next version ;)

Thanks you for the fee checker '

the fee that blockchain info wallet recommend turns out to be also to low sometimes so confirms would take hours.

I prefer to use this; https://www.viabtc.com/tools/txaccelerator/

Indeed, that's why i created a tool like this... Instead of repeating the same old things every time a user didn't add enough fees, you can now point him to my url ;)


As you can read in the OP, this tool isn't meanth to ask a miner to insert your tx into the block they're currently working on. In fact, if my tool detects the fee isn't high enough, the page you linked to is shown as one of the possible sollutions

Indeed, my suggestion is a possible solution to unconfirmation problem comes with low fee.

I just wanted to share my humble opinion on a possible solution.

Ah crap it was live.blockcypher.com . I really mix up names with blockexplorer and live.blockcypher.com explorer.


I think most of the users always leave their bitcoin tx tab idle and gets back to other work so they might miss it to check their transaction again. Anyway it was just a miscellaneous feature that I suggested to be included which is of least priority atm as you might be focusing on technical things first.

I've added some new tools, and also made some improvements. My scripts no longer uses an external api. Instead i made sure every function used my own node's json-rpc connection to execute my scripts.

What is currently implemented:

• An (in)sufficient fee checker
• A Raw transaction decoder
• A Sig checker
• A Raw transaction generator
• A Raw transaction broadcaster

At the moment, everything looks really ugly, and some extra functionality still needs to be implemented, but feedback is always welcome :)

To-do list

• Create a member area for functions that cannot be executed anonymously:
  
  
  • a mailer where you can add transactions, and receive an email once the transaction confirms
  • a repeat-broadcaster where you can add raw transactions and my system will re-broadcast them hourly untill they confirm or get removed
  
  
• give everything a nice design
• extra tutorials
• coupling the raw transaction generator to the fee checker, so you can easily create a doublespend for the unconfirmed inputs when the fee isn't high enough
• extra security

I have wanted to know about this for awhile now and I'm glad I found this thread. I use blockchain.info and it pits a recommended amount automatically but its too high for my liking so I use less. The problem is how less. Well this helps me a great deal with that problem otherwose I would habe to use trail and error which is not ideal.

I have decided to look at this website as a real project, so i made a subdomain:
All future testing and implementation of new functionality will happen on:

http://beta.mocacinno.com

At this moment, i'm fixing following functionality:

• http://beta.mocacinno.com/page/feechecker => When testing for (in) sufficient fees, i added a CPFP AND a double spending wizard, i'm currently testing/fixing this code
• http://beta.mocacinno.com/page/feeestimate => I added a fee estimator module, i'm testing if the results are more or less reliable
• since so many new tools were developed, and the mainpage became kind of a dump, i started using mod_rewrite to make nice, readable and shareable urls, so it's possible some internal links are broken (i'm actively searching for broken links!)

Anybody who is feeling generous and has some spare time: feel free to beta-test the above functionality on beta.mocacinno.com and give feedback whenever you find a bug, or if you'd like to see the tool behave differently.
Since this is a free project, there is no bounty for finding bugs, but if you find a big one, or prove to be a big help, i'll add a section with contributors and add your name ;)

i want to joined mr,, for  it

I'm really looking for this tool,used to have a lot of issue sending my bitcoin,I need a raw transaction so I can rebroadcast and a tool so I'll know the fee when sending my bitcoin,have bookmarked it and will definitely used it,you should post a donation if visitors wants to support your site and tools,

i currently fixed loads of bugs, added some SEO optimizations and i'm currently searching for link trades with bitcoin-related websites... Preferably sites that offer (free) services.

I also added redirect rules to redirect all traffic to the SSL version, www subdomain, so visiting http://mocacinno.com should automatically redirect to https://www.mocacinno.com
If anybody find any bugs with this redirection, don't hesistate to PM me :) It's a free service, so i'm not offering bug bounty's, but if you want to, i'll add your name to an online contributor list ;)
