P2P Trading in Cryptoanarchy

Speakers: m52go

How can we trade directly with another party on the internet, without involving a trusted third party or legal system? Is there a way to trust the other party to be honest? Bisq recently implemented a dispute resolution system that keeps control of escrowed funds between the 2 traders only (2-of-2 multisig, instead of 2-of-3 multisig with trusted arbitrator). See how it combines game-theoretic, financial, and cryptographic tools to accomplish sovereign (and anonymous) peer-to-peer trading.

An Overview of Monero’s Adaptive Blockweight Approach to Scaling

Speakers: Francisco "ArticMine" Cabañas

Monero has a unique among the major crypto currencies approach to scaling, that relies on a penalty driven adaptive blockweight (blocksize) and a minimum or tail block reward. This is fundamentally different from the fixed blockweight and falling bock rewards that are prevalent in Bitcoin and Bitcoin clones. We will provide an overview of Monero’s adaptive blockweight, fee market and how blockweight differs from blocksize together with the dual median changes and transaction changes that were introduced in the 2019 spring and fall network updates. We will compare adaptive vs fixed blockweights, and the impact of minimum block rewards (Monero) vs falling block rewards (Bitcoin and Bitcoin clones) on long term network security.

15:55-16:25

Nym

Speakers: Harry Halpin

Nym is a decentralized and incentived mix-network that can defeat even global passive adversaries. This event will launch the "alpha" Rust mix-net of Nym, and demonstrate the use of validators to create anonymous authentication credentials to access the mix-net.

16:30-17:00

Digital integrity of the human person

Speakers: Alexis

Description/Abstract: Every human evolves today in multi-dimensional physical and digital environment. If each individual is to keep its individuality and autonomy in its daily choices, it must be protected and given effective tools to defend its own autonomy. Recognizing that human life has been digitally extended must question ourselves on what makes us human today. Should personal data be considered as component of the person, rather than objects that can be owned by whoever collects that data? Should our digital integrity be protected? If each human person already has a right to physical and mental integrity (Swiss Constitution article 10 al.2), shouldn't it have a right to digital integrity? This talk will introduce this new legal concept, its possible implications for data protection and how this concept could be introduced in the current legal framework.

17:05-17:20

cyber~Congress

Speakers: cyber~Congress

Our mission is to fuckGoogle and other megacorps. We are geeks that build open-source things. Code first. Everything else later.

17:50-18:20

Parallel Polis, Temporary autonomous zones and beyond

Speakers: Juraj Bednár

Cryptoanarchy creates spaces of liberty in the virtual space - encryption, anonymity, free trade using digital money. Can we use some of the principles to achieve liberty in physical space? How to create parallel social institutions.

19:25-19:55

Adventures and Experiments Adding Namecoin to Tor Browser

Speakers: Jeremy Rand

The Namecoin and Tor developers are running a new experiment: the GNU/Linux Nightly Builds of Tor Browser now have optional support for resolving Namecoin's .bit domains. This experiment aims to provide a fix for the long-standing UX problem with .onion domains: the lack of human-meaningful names. With Namecoin, you can access onion services via nice, memorable addresses like http://federalistpapers.bit/ instead of http://7fa6xlti5joarlmkuhjaifa47ukgcwz6tfndgax45ocyn4rixm632jid.onion/ . In this talk, I'll cover the goals of the experiment, the work that went into getting here, and the work that remains to be done.

20:00-20:15

Building an (Actual) Alternative

Speakers: Deanna MacDonald

Privacy and freedom within the context of cryptocurrencies, zero-knowledge-proof systems, decentralised protocols and other privacy protection layers is about co-creating and co-shaping alternatives to empower individuals to control their own data. What is the role of Monero in building an actual alternative and preventing the public ledger from becoming another behaviour extraction and surveillance tool? As a community, what type of counter-narratives do we need to create to support this movement?

13:00-13:15

20:45-21:30

Bitcoin to the Post-Quantum Era

Speakers: Dragos Ilie

Given the amount of funding and research that recently goes into quantum computers, it seems inevitable that at some point in the (near) future these machines will become a reality. With my physicist's hat on, this is exciting and amazing news, but as a cryptographer this is a nightmare. Most of our most efficient and widely used signature schemes would just go away in the blink of an eye. Is this the case for Bitcoin? Can we do anything to move Bitcoin to the Post-Quantum Era? In this talk, I present the basic principles Quantum Computers rely on to perform certain calculations much faster than classical computers. We give a beginner’s explanation to some quantum algorithms that can undermine Bitcoin’s security and show how they can be used to hijack transactions. Finally, I present a protocol upgrade for Bitcoin that allows users to securely transition their funds to quantum resistant wallets even in the presence of a quantum computer!

21:30-22:00

3.8 Billion users' future: Email 3.0

Speakers: Sam Tuke

Hundreds of messaging platforms have launched and failed over the last 50 years, while one Open Standards, and mostly Open Source powered decentralised platform has conquered the world. What is the magic formula that has powered email to adoption by 3.8bn users, and what is the future of decentralised messaging as firms like Google and Facebook try desperately to replace it?

14:05-14:20

Proof of Less Work

Speakers: Cheng Wang

I would like to share my work on reducing the energy consumption of PoW without sacrificing security. My new type of algorithm is called PoLW, inspired by the recent work of Itay, Alexander, and Ittay. For a practical system where mining is profitable, PoLW might actually improve network security.

14:30-15:00

Open Next - Learning from Open Hardware: DevOps and Continuous Integration for the Production of Big Machines

Speakers: Mario Behling

Continuous Integration was a big buzzword with software projects already years ago and it is standard today. In projects such as Pocket Science Lab we took the idea of Development Operations a step further and apply these concepts to hardware. The increased speed of development and the possibility to produce different prototypes with a click almost feels as if we deploy software automatically. What would happen if the industry would be able to change in the same way? How could we shorten the time from prototype to production and market? What is missing to build complex and really big machines? How can standardization and machine readable requirements documents help us to create sustainable hardware and solve the problems of our time? These are some of the questions we will explore in this session based on our research within the EU Horizon 2020 project on collaborative product creation.

15:15-15:30

Designing a communal computing interface

Speakers: Matilde Park

How does a full peer-to-peer stack change how we organise and present user interfaces? If the PC was a 1970s desk for single-player computing, what's the right way to think of the way we actually use networks: communally? Matilde Park presents some findings from working on Urbit, an open source project tackling a peer-to-peer internet from scratch.

15:35-16:10
