sx now auto creates a config for your user if one doesn't exist.

https://github.com/spesmilo/sx/commit/71eebef3d702507643058863206a79a047623c7a

next goal is support for BIP32 deterministic wallets.

libbitcoin
libbitcoin is a community of developers building the open source library, tools and implementation necesary for a free, independent and vibrant Bitcoin. In this way we are helping to build a better future. Values: privacy, scalability, integrity. See more info in our docs.

Obelisk: scalable blockchain query infrastructure
Obelisk is a scalable blockchain query infrastructure. See the setup guide. There is a public server available at obelisk.unsystem.net:8081 but I wouldn't use it for anything production (besides testing). Uses libbitcoin for asynchronous full node Bitcoin implementations on the backend that connect to a load balancer. The load balancer distributes blockchain requests among the workers on the backend.

sx command line utilities - Empower The Sysadmin With Bitcoin Tools
My aim with this project is to provide a set of modular Bitcoin commandline utilities, that admin types can engage with Bitcoin functionality without having to write code. By chaining all these commands together in different ways, you can do offline transactions, maintain a wallet, work with deterministic keys, ...

It would be cool to see Bitcoin wallets written in bash script using these tools to handle the core functionality. I believe the more we give good tools to the community, the more we can decentralise development and increase access to the core technology for all types.

python-obelisk
This is a collaboration between Pablo Martin's ZMQ/Obelisk implementation, and Robert Williamson's blockalchemy library with code from ThomasV's Electrum. python-obelisk is a pure Python client-side implementation of the Obelisk protocol. A pure Python library is great because it can be deployed easily without requiring dependencies. This allows code to be ported across many platforms such as the mobile phone with Kivy, desktops or any platform running Python.

sx wallet: ncurses terminal wallet


dat.wallet: pure Python tutorial wallet for Linux, Android, Mac, Windows
Me and Taylor Gerring (Hive wallet) coded this example wallet in 2 days in pure Python. It uses python-obelisk and is meant to be be an example for other coders to understand how wallets work. We'll work slowly on more tutorials and docs. It uses kivy and has no dependencies, so can be used on the mobile phone.

This is great for wallet developers and GUI designers who want to create their own skin or special wallet with specific features. For example: wallets for traders, branded wallets for businesses and specific payment applications that use wallet functionality.



DarkWallet browser plugin
The beginnings of the DarkWallet project. We are focusing mainly on the underlying technology and how to create usable crypto products for the entrepreneurs of the future. This means a strong multi-discipline synthesis between designers, users and coders. See more of our vision on the unSYSTEM wiki.

Hi!

The code is not great, but it is merely instructive for people to understand how to use the underlying Bitcoin library and functionality.

Your email is too long and looks like spam. No one is ever going to read that. Especially if it goes to low level employees first. You link a Bitcoin website as your source.

Thanks to rbdrbd, in Obelisk there are now init.d scripts, setup script and logrotation:

https://github.com/spesmilo/obelisk/tree/master/scripts

Going to be testing these. Would appreciate any feedback to improve them.
168  Bitcoin / Development & Technical Discussion / Re: sx command line utilities - Empower The Sysadmin With Bitcoin Tools on: December 14, 2013, 03:35:06 AM
setup script for actually configuring obworker and obbalancer (as their own user, etc): http://pastebin.com/MWJsaXKY
obbalancer init.d file: http://pastebin.com/43ivabs5
obworker init.d file: http://pastebin.com/MiFfgA3s
obworker log rotation: http://pastebin.com/udJypGSa

There's a setup script, obbalancer init.d script, obworker init.d script and obworker log rotation script.

Questions to everyone:

1. Where should the scripts normally reside on your system? Would the setup script be installed with the package?

2. What's the standard GNU way of distributing them? scripts/? How would I name them?

Thanks.

Thanks
I can maintain debian / buntu docker files for sx / oblisk etc once I understand the dependencies in more depth.

just been reading about this. I'm not an admin guy but docker sounds really cool. update any progress you make on this.

we have a wiki: https://wiki.unsystem.net/

171  Bitcoin / Alternative clients / Re: libbitcoin on: December 12, 2013, 04:46:15 PM
I've created a new library which will have non-critical code (like
deterministic wallets, key formats and selecting outputs) ported from
libbitcoin to libwallet.

This will keep libbitcoin focused on its core functionality. The client
side stuff is less important considering all the wallet development done
in Python, JavaScript .etc libbitcoin is aimed at server software.

https://github.com/spesmilo/libwallet

The install-sx.sh has been updated to reflect this. Users simply need to
re-run the script to update.

BTW we have a mailing list: https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/libbitcoin

How will you prevent JS injection, browser vulnerabilities, etc from getting the privkeys?

https://wiki.unsystem.net/index.php/DarkWallet/DesktopCounterpart

Also the tech we build will benefit other wallets which we can also take code from like Kryptokit or SpareCoins. So we provide backend and devs can make the frontend. We have a long term vision for this stuff.

We made it!

Time for updates. This is an exciting moment. We've been slaving, writing code for 3 years now through hardship and all kind of opposition. With these funds, we can invest wisely into critical things blocking our progress and help the Bitcoin space to grow. We are social entrepreneurs, and our goal is to use technology to affect a new way of life.

Here's an interview with Peter Todd (aka retep). Peter is a well reknowned Bitcoin thereotician. He helped create the trustless mixing concept and chose the CoinJoin name. Peter has also co-developed the more recent CoinSwap proposal- a highly technical for ultra anonymity of sending Bitcoins. Peter is responsible within the community for researching and creating new concepts to improve privacy of Bitcoin transactions, scalability of the blockchain and a well functioning network.

Peter Todd interview, http://www.youtube.com/watch?v=tb-QHhbKMAY

The meeting was a success. Our community is well organised, super passionate and with lots of spliff. We've set our goals and reached consensus with how we want to progress. More important than the project itself, is bringing the right minds together to collaborate on a vision. We can write code, but it's about writing tools for the future not tech toys only we will use.

During the meeting, Taylor Gerring (Hive wallet) and Amir Taaki (libbitcoin) created dat.wallet, a new Android Bitcoin wallet by leveraging DarkWallet technology. Amir says "just like when we created trustless mixing, we were able to use our tools to very quickly create a prototype Bitcoin application."



libbitcoin, the base for our development efforts has been a long time in development. We have an extensive toolset and scalable architecture. Now we are deploying our infrastructure for production. This will entail extensive testing on multiple platforms and distribution efforts. In development are new components to better handle the blockchain and network.



Here is a prototype which you can find in our git repo. Sem (frontend developer) says "We had to go initially with a Chrome extension despite preferring Firefox. Chrome has a more stable API which enables rapid development during the early stages. Later we will port the code to Firefox. It's written to be easy to port."

Note: we don't recommend Google Chrome. Use Chromium or Firefox (better).

For those who need more juice, see the DarkWallet living document which details our ideas for DarkWallet in more depth.

Dark Wallet wants to enable the power of crypto for users of the web. We are the developing the tools that will empower web developers to create services utilising the full power of Bitcoin.

New library for interfacing with Obelisk servers and doing Bitcoin functionality.

Pure Python so library is easily portable to platforms that can run a Python interpreter.

https://bitcointalk.org/index.php?topic=354607

https://github.com/darkwallet/python-obelisk/

See examples/ directory.

This is a collaboration between Pablo Martin's ZMQ/Obelisk implementation, Robert Williamson's blockalchemy library and code from ThomasV's Electrum.

Obelisk is a scalable blockchain query infrastructure. See the setup guide. There is a public server available at 37.139.11.99:9091 but I wouldn't use it for anything production (besides testing).

A pure Python library is great because it can be deployed easily without requiring dependencies. This allows code to be ported across many platforms such as the mobile phone with Kivy, desktops or any platform running Python.

Features:

* Blockchain queries and navigation through Obelisk servers.
* Construct & sign transactions.
* BIP32 hierarchical wallet.
* Traverse the blockchain using a syntax similar to Django ORM / SQL alchemy.

Use cases:

* Website payment backend (store and manage the keys yourself).
* Wallet software.
