9  Bitcoin / Bitcoin Discussion / Throw Charlie under the bus and wash your hands clean of your biggest advocate on: January 29, 2014, 04:56:38 AM
http://www.coindesk.com/charlie-shrem-resigns-bitcoin-foundation-silk-road-arrest/

Charlie was one of the biggest advocates and architects of placating to power structures in order to curry favour.

Now he has been neutralised and his friends wash their hands of him.

Naturally this is painted in terms of his responsibility and guilt.

This obsession with image affects how Bitcoin develops as a free market tool. Bitcoin's interest is advanced in different directions depending on the groups controlling it. If corporates and people working with central power dictate development, then satoshi's vision will evolve into CorpCoin. Software is art. Technology is never neutral. All technical decisions involve tradeoffs and the best path isn't always clear. It's easy to become gradually corrupted if you ignore your principles and willingly sacrifice your integrity.

11  Economy / Service Announcements / Twister is amazing on: January 02, 2014, 03:19:45 PM
this is the future of crypto messaging:

http://twister.net.co/

better than bitmessage. inspired by bitcoin. uses bittorrent with a blockchain. made by former xine dev. uses libtorrent (libbitcoin was inspired by libtorrent).

this is it.

12  Bitcoin / Development & Technical Discussion / about alternate chains vs using bitcoin blockchain on: January 02, 2014, 03:12:31 PM
re: twister and other protocol layers.

the argument to use the bitcoin blockchain is that it offers absolute security. by using a new chain, some portion of that power can peel off and attack you. this means that alt chains will always have trouble getting through that initial hump where they are vulnerable to mining attacks.

however alt chains increasingly serve a variety of market purposes (such as twister). there's varying degrees of risk on how much X mining power is likely to be used (like when pools attack some altcoins in the past to prove a point), but if the market incentive is greater and grows quickly enough it can get past this hump.

especially now since the bitcoin blockchain is associated with money and has a high level of security (money demands high level of security), it's difficult to design a successful altcoin. but there are chains providing other purposes and can tolerate more risk. they are also optimised for their use case and so more efficient than simply relying on bitcoin blockchain, and hence far cheaper.

twister is the best example of this. i've been thinking and they've made the right decision making an altchain. it's the future, and i think beats bitmessage. i'm making some notes here:

https://wiki.unsystem.net/index.php/Twister

edit: changed my mind about twister. It's more nuanced than that. we can use a combination. see this discussion here:

13  Bitcoin / Bitcoin Discussion / Using the blockchain as a tracker + BitTorrent for Silk Road seller pages on: December 20, 2013, 08:45:09 PM
I know that several groups of people are working on this.

* FrostWire BitTorrent developers.
* ThePirateBay
* zooko of Tahoe-LAFS
* A friend of mine from IRC
* Bitstorage by Sarchar
* twister by xine dev

The basic idea is to embed searchable hashes in the blockchain that can't be censored. Then use these to fetch that actual data from a DHT network. This takes *a lot* of pressure off the blockchain from people who want to throw lots of data at it, and allows you to potentially use this scheme to allow gigabytes of data to be retrieved. It's basically proof of sacrifice.

I think this has many many very useful future applications. If we have our privacy aware wallets, identity, p2p communication (BitMessage or even XMPP) and distributed reputation, then together with the tools for managing multisig (distributed escrow), we can use this innovation so sellers can maintain their own page of goods that can be updated.

Think something like Tor or Freenet but fast to load and encrypted. All these tools together enable a decentralised Silk Road. If the seller on the remote end is a robot, then you could communicate with the robots over p2p encrypted protocols to send messages and update the page (like a forum or Wiki). There's very many possibilities from this tech. I especially like using the blockchain as an authority for human usable names for identities and cipherweb locations.

btw maybe you should pay to people when you retrieve the file. therefore depending on how fast you want the file, you put up an auction and gather the bids, then a special transaction is created for atomically exchanging the file for your credit (as agreed by the bid).
14  Bitcoin / Project Development / unSYSTEM projects: libbitcoin, DarkWallet, developer tools and video interviews on: December 15, 2013, 08:42:49 PM
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.

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

16  Bitcoin / Bitcoin Discussion / Dark Wallet has surpassed $100k donations on Indiegogo on: December 11, 2013, 04:06:51 PM
http://www.indiegogo.com/projects/bitcoin-dark-wallet

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.
