1  Bitcoin / Project Development / [ANN] Percy, Persistent Bitcoin Transactions on: June 01, 2017, 02:58:21 AM
Hey guys I created a tool, percy, that will make your transactions persistent by resubmitting them periodically to the network.

Ideal use case is for someone with a transaction where they can afford to be patient (like a re-organizationing transaction to ones self or an incoming transaction with a lower fee and a known customer). Or where you can let subsequent child transactions add an additional bounty on payment (like when re-organizing coins in your wallet). It doesn't do anything too complex really. It just resubmits your transactions to the network every 6 hours until it confirms. So even if you put in a transaction during bitcoin's "busy" periods with an average fee this will continue to resubmit the transaction to the network until it confirms. The method used to do so is not complex (see source code here) and can be self hosted if desired (I run a test box on a raspberry pi out of my home).

Would love your feedback and if you spot a bug or a feature request please report it on github.

According to 21.co's Fee Chart there have been 60k+ transactions that have confirmed in the last 24 hours with a fee < 100 sats/byte. If you can be patient Percy can make sure your transaction persists until it's one of those confirmed.

btcaddrtocsv v0.1 relased

Hello everyone Id like to announce the v0.1 release of btcaddrtocsv. A CLI tool that I use to convert public bitcoin addresses to csv files for import into a multitude of tools. Id also like to announce that in addition to the basic python script that can pull one address Ive also (in head) created a bash script to cycle through a number of BTC addresses. Here is a link to the github page for the project and here is the link for the 0.1 release.

Please remember that this tool depends on the blockchain.info api so if youre using it on a machine that cant reach the internet it will not work. Ive been using this tool successfully for months now so I believe it to be stable. Please report bugs to the issues page on github. If you like what Im doing here please consider donating using address 14UbKCCjxpU1jnzZHKGRf8xaP2a5RS4n9R.

Please remember, if you are using the new bash script to process several addresses at the same time, to create a directory called csvs for your csv files to be output to.

4  Economy / Service Discussion / Blockchain.info API Problem on: October 25, 2013, 05:49:38 PM
Hey guys I'm trying to pull information about a transaction from blockchain.info's API. I think their API isn't working as defined.

From the API Documentation Page:
Quote
Single Address   
http://blockchain.info/address/$hash_160?format=json
http://blockchain.info/address/$bitcoin_address?format=json
http://blockchain.info/rawaddr/$bitcoin_address
Optional limit parameter to show n transactions e.g. &limit=50

But when I do:
https://blockchain.info/address/1KMLjhgjGLxZTJT5TSWxV2HCZHBqpDEpa1?format=json&limit=100

I only get the first 50 transactions. I believe that the API is ignoring the limit command and manually placing you with only 50 transactions (Quick way to check is to find the word "result" as it only appears once per transaction).

Can anyone assist? Or does anyone know an email where I can email Blockchain directly?

Anyone tried mining with this:
http://www-03.ibm.com/security/cryptocards/pciecc/overview.shtml

It's an IBM cryptographic co-processor. It should be able to do hashing if my understanding is correct.

10  Economy / Securities / Decentralized Stock Market on: February 28, 2013, 04:42:02 PM
So I was thinking about bitcoin and it's natural equivalents in the fiat currency market and I realized that stocks are going to need a rethinking to work properly. So I sketched out the basics of a stock system. This wouldn't include the actual exchange floor and services would pop up to fill that void. But it would include the mechanisms of transaction. Forewarning! I haven't worked out all the math yet. Here be me diagram what do you guys think?
