1  Alternate cryptocurrencies / Announcements (Altcoins) / derpina, a cryptocurrency tipping bot for Mattermost on: August 16, 2020, 05:13:41 AM
Doing my part for a widespread cryptocurrencies adoption, I proposed to my company to implement a system where any employee can "tip" another one using cryptocurrencies.
The idea being that if you help a coworker, deliver before it's due, impress someone with something you've done, (s)he can tip you with coins, which is less awkward than giving you $1.
When it comes to money exchanges, at least here in France, things are always complicated and there's almost no way to bring innovation in this field. For this reason I made it "fun" and chose DOGE as the tipping asset. Note that this can be changed only by modifying the configuration file.

We use https://mattermost.com as our messaging solution, and the software I wrote uses Mattermost's outgoing webhooks to summon the bot.

So here's the result of a couple of days of golang programming https://gitlab.com/iMil/derpina

Feedback very welcome, feel free to use and modify it as you wish.
2  Bitcoin / Development & Technical Discussion / mnemocheck, checks that your seed phrase matches an address on: June 29, 2020, 07:04:05 AM
I've always had this small doubt that those seed words I wrote down and encrypted might have a typo, or be wrong, and I obviously didn't want them to hang around in clear text or via the network for anything to snoop it.

So I wrote mnemocheck, basically a Dockerfile along with a small bip-utils based python script that derivates the first public address from the mnemonic, it reads them from stdin and the container should be launched with --network none. It knows about Bitcoin, Litecoin, Dogecoin, Dash, Ethereum and XRP (actually what bip-utils supports).
Use it with caution, only pipe on a local, trusted machine, and using encryption tools like GPG, password-store or OpenSSL with the right algorithms.

Here it is https://gitlab.com/iMil/mnemocheck/
3  Bitcoin / Development & Technical Discussion / Goxplorer, a Bitcoin blockchain parser package written in golang on: November 11, 2019, 02:56:16 PM
Hi,

A couple of weeks ago I started a toy project in order to dig into blocks structure, and one thing leading to another, it evolved into a pretty usable block file parser Go package.
I am aware of btcsuite, but TBH I found its documentation really hard to read and the project way too large for the simple task I wanted to achieve, so I took the opportunity.

So here it is, I present you Goxplorer (pun intended) https://gitlab.com/iMil/goxplorer, it supports pretty much all locking mechanisms including natives and P2SH embedded SegWit ones. It has the ability to add callbacks for every parsed transaction and/or block, which makes it fun to play with.

It still needs more documentation and testing, but I thought you might find it useful.

Hope you like it,

Cheers,

iMil
