Cypherpunkd Episode 038: “Voucher-Safe P2P Digital Cash – Problems it Solves, Problems it does Not” – Justin of Voucher-Safe

Posted May 25th, 2011 in Cypherpunkd by admin

Justin from Voucher-Safe is back to discuss some Problems that Voucher-Safe is out to Solve, and some things that it has no interest in solving, namely the “better money” problem. Listen in to hear what Justin has to say about this. Also discussed are some early history of pre-internet days when the feds cracked down on an early barter network that exchanged warehouse receipts… Interesting stories…

Some more details on how Voucher-Safe has many layers with Zero-Knowledge like interactions. You can’t give up, what you don’t know. You don’t need to know, what is not necessary to know.

Justin also discusses his positive feelings about what a system like Voucher-Safe can do for Bitcoin, referencing the recent show with Mike Gogulski on Bitcoin laundry systems, and all remailer type mixing of transactions. How Voucher-Safe can fit right in with bringing many things to the Digital Cash/Value Transfer System talbles that Bitcoin by itself does not solve.

We then get into the XMPP infrastructure that Voucher-Safe uses for inter system communications and client comms with users. Interesting setup, we discuss how some elements of Voucher-Safe can be run on Low Trust Servers with an economic incentive for those that run them. We also talk about some “best practices” for RPC/Request-Response calls over XMPP, he talks about existing solutions and things like timeouts, queues, and callback ids can be used. First half non-tech, second half heavy tech. As a whole Good Stuff.

    I really enjoy listening to your show, I have a long way to go but I’ll listen to them all.

    I am surprised there not much comment here yet.

    I REALLY hope you can fix all of your technical difficulties in the upcoming shows.

    In the recording of this emission the host is ~10x quieter than the guess, Meaning I don’t hear anything you say and the breath of the host is much louder than your voice.

    Thanks.

Cypherpunkd Episode 036: “MondoNet” – A Global Decentralized, Ad-Hoc, Wireless, P2P Mesh Network – Aram Sinnreich

Posted May 23rd, 2011 in Cypherpunkd by admin

Aram Sinnreich from the MondoNet Project joins us to remind us of the words of John Lennon: “Imagine no Centralized ISP’s and Government Controlled Internet, Imagine All the People living in P2P Communications Liberty”. Well those are not Arams words, but if you are not aware of projects such as this, you are in for a treat. This is not your average Darknet that sits on top of the existing internet. This is an Alternate Internet, P2P, Device to Device. Agorist Style… Enjoy the Show.

Background:

Although the Internet is highly decentralized in its communication and social patterns, its technical and regulatory foundations are extremely hierarchical, due to centralized control by organizations like ICANN and the oligopolistic ownership of the access business by a handful of broadband ISPs and wireless carriers (Wu, 2010). As a result of this centralization, digital communications are compromised by a degree of surveillance and censorship that would be unthinkable in traditional social arenas, threatening our cyberliberties and “e-speech” rights (Sinnreich & Zager, 2008). Seemingly disparate issues like network neutrality, intellectual property treaties and national security measures, taken in combination, threaten to produce a communications environment in which innovation is stifled and normative cultural behaviors are criminalized and punished by censorship, fines and/or imprisonment. One potential solution to this problem would be to create a new communications platform based on existing Internet protocols, but with a decentralized infrastructure free of the bottlenecks and chokepoints that plague the current system. Specifically, this new infrastructure would use mesh networking technologies to produce a stable, ad hoc global wireless network in which each peer is a router, server and client combined, and in which no single state or organization can effectively censor or surveil the population on a massive scale.

Cypherpunkd Episode 026: “HOWTO: A Tyrants Guide to Taking Over Bitcoin and Licensing Miners + Bitcoin Over Freenet Project” – da2ce7

Posted May 12th, 2011 in Cypherpunkd by admin

Cypherpunk da2ce7 lays out the HOWTO for a Complete Government Takeover of Bitcoin, how they can lock out miners that are not registered with the Government and 0wn it. We get into the Bitcoin over Freenet Project which creates a parallel communication and Bitcoin network, adds an ANTI-DDOS layer, and Anonymity layer to Blockchain exchange, distribution, and updates and p2p Payments. He then tells us how Bitcoin could survive a complete internet shutdown, albeit with 2 day payment settlement times using a Freenet based data p2p distribution/sync system.

This episode is Pure Fun.

    Wow, awesome episode. I love the whole freenet + sneakernet >> internet killswitch shit. This show is getting close to Snow Crash.

  2. Brian McQueen says:

    In the show you mention a Sneakernet type of operation used by ships-at-sea? I want some information on that for the next Meetup. Got any leads or URLs?

      We will try to get the source on for a show.

Cypherpunkd Episode 023: “Voucher-Safe – Secure P2P Digital Cash and Infrastructure” – Justin

Posted May 4th, 2011 in Cypherpunkd by admin

Justin tells us that Voucher-Safe has entered the building. Listen in and get a great overview of what Voucher-Safe brings to the Second-Realm and mucho info on the infrastructure. Operating in a P2P via Jabber/XMPP protocol from clients to servers to an entire infrastructure all the way to the actual Issuers of the assets. It has operational incentives built in at every level of the system. We hear how this system was conceived after the jackboots confiscated all the gold of the people using e-gold and prosecuted the operators, while they turn a complete blind eye to prosecuting Citibank for what its users do with their cash outside the bank. Cash is the way to go. Voucher-safe has no accounts… you have wallets, and exchange over a p2p network protocol xmpp these bearer certificates. We hear how close the system is to full production and the initial issuers. Justin talks about some of the protocol, how to integrate your own software in with the API. We get a little technical at times, but far from where we would have gone had time permitted, save that for the next episode. Check out the software, view the screencasts, join the forums and get some funny-money assets to test out the system.

Cypherpunkd Episode 019: “Global Bitcoin Stock Exchange and Bitdrop” – Nefario

Posted April 28th, 2011 in Cypherpunkd by admin

The Global Bitcoin Stock Exchange, Bitcoin, Open-Transactions, Loom, GSF, CoatCheck… Buckle your seat-belt Dorothy, cause Kansas is about to go bye-bye. This episode is not for the faint of heart. Nefario starts off telling us some of his background motivation for creating this project. How it started off as a reputation system, but then the GLBSE seemed like a need to be fulfilled first. Discussion on the recent spike in Bitcoin adoption and market activity. We cover features of the GBSE, things working now, things being coded now. How they started with Open-Transactions, but moved to their own backend, and future plans for their replacing most of the backend with future Open-Transactions releases. We go over the Tutorial showing basic features of the system, Register, Deposit, Withdraw, Transfer, Place Order, Show Orders, Issue Assets. Ricardian contracts example of issuing your own Bond, pgp key signing of contracts. Integrating Loom and GSF Globals as an additional settlement/payment currency in GLBSE. Integrating Open-Transactions and other systems. Possibilities of P2P comms with future clients, encryption transports, encrypted messages over OTR. Issues of criminal organizations attacking this system, the need to take it deep in the darknets.
Nefario also lets us know about his other future project “Bitdrop” a distributed package delivery system with couriers getting paid with bitcoin. Programmers wanted! Doing onion routing and geocache, f2f networks. We discuss massively distributed p2p hawala systems with anyone and everyone an exchanger for in/out of second realm currencies. GLBSE METATRADING and his article on anonymous exchange networks.
