Crypto Renaissance: Back to the cryptoanarchist roots

Why we should come back to the cryptoanarchist roots in order to achieve more freedom, and at the same time refuse using of crypto technologies to improve the centralized authoritarian society.

In few days (9.1.2019) Bitcoin will have its 10 years anniversairy

What do we achieve after this time:

We cannot trade Bitcoin freely, draconian KYC /AML bureaucracy is required for almost all transactions (!)
We call blockchain disruptive subversive technology. At the same time we use it to improve the authoritative state institutions(!)
All decentralized by-blockchain products (e.g. ICO, securities, funds,.. ) are completely regulated by the governments.

Church of Monero Live Mass

The Church of Monero holds weekly "Masses" where other disciples of privacy send each other a small amount of Monero in a circle-of-trust "Ring Ritual".

This activity:
1) generates new Monero outputs which enhance the Monero ring-signature privacy set.
2) gives members a chance to practice sending/receiving Monero.
3) provides a sense of meaning.

For each week the members participate successfully, they earn 1 Faith Point. Faith Points are non-transferable, distributed database entries that function as a developing, internal reputation system.

The Church of Monero holds these events twice a week on our public telegram channel @churchofmonero. We meet Wednesdays @ 08:00 UTC (for people living in Asia) and Sundays @ 18:00 UTC (for people living in NA/EU). Church members can only earn a max of 1 Faith Point per week, even if they attend both Masses.

We have successfully held 16 weeks of Mass. The Faith Points can be seen in the attached photo.

Towards fair data society

We are at the crossroads: data slavery or fair data society?
The talk will present Fair Data Society initiative and give an overview of the protocol with a call-to-action to build projects in an ethical way on fair data principles.

We live in a world where individuals are exploited for their personal data and privacy as human right is ignored while handful of actors are unfairly amassing wealth generated by personal data (think Facebook and similar). In short, we can call it data slavery.

Fair Data Society (FDS) is an independent non-profit organisation, initiated by Datafund project, that follows a vision where personal data is owned by individuals and the value of data is – contrary to popular centralised services – fairly distributed among its owners. Data exchange is on a need-to-know basis, according to user consents and conditions while human rights and privacy are respected.

To achieve this, FDS is developing fair data protocol where personal data is semantically organised and stored on Swarm, and fairdrop dapp for ethical data exchange (first release in September). FDS components can be reused by any other project. Moreover, FDS is actively connecting various stakeholders such as developers, academia, regulators, NGOs and governments to drive social change and raise awareness towards mentioned goals.

The talk will present FDS initiative and give an overview of the protocol with a call-to-...

Introduction to Game Theory for Blockchain

Participants will learn about basic game theory concepts by playing games with each others where they win/lose physical tokens.

Game theory is the study of mathemathical models of conflict and cooperation between Intelligent and rational decision-makers. Blockchain is a technology allowing the creation of decentralized ledgers without requiring a trusted third party to guarantee its authenticity. Actors still need to make particular actions in order for the ledger to work as expected. In order to make actors behave in a manner leading to the system working, the system must reward honest actors and punish dishonestly ones throught game theoretical incentives. For example, in Bitcoin, miners are rewarded when they publish blocks which are included in the longest chain.
This workshop will introduce basic game theoretical concepts in the form of simple economic games played between the participants. The workshop does not require previous knowledge and everyone is welcome

Namecoin as a Decentralized Alternative to Certificate Authorities for TLS: The Next Generation

Certificate authorities suck, but the proposed replacements (e.g. DNSSEC/DANE) aren't so great either. That's why one year ago at the 34C3 Monero Assembly, I presented Namecoin's work on a decentralized alternative to certificate authorities for ...

Certificate authorities (CA's) pose a serious threat to the TLS ecosystem. Prior proposed solutions (e.g. Convergence, DANE, HPKP, CAA, and CT) simply reshuffle the set of trusted third parties. In contrast, Namecoin solves the underlying problem: if you know a Namecoin domain name, you can find out which TLS certificates are valid for it, with a threat model and codebase nearly identical to the battle-hardened Bitcoin. One year ago at the 34C3 Monero Assembly, I presented a design (with implemented, working code) for accomplishing this in the real world of uncooperative web browsers, with best-in-class attack surface, good compatibility, and good scalability.

But there was still much that could be improved, ranging from ending our reliance on HPKP API's (which are being phased out), to preventing the browser's TLS implementation from leaving your browsing history on the disk, to sandboxing Namecoin's certificate override code so that it can't compromise non-Namecoin traffic even if exploited, to supporting Firefox and Tor Browser (both of which posed unique challenges), to name just a few. This talk will cover a wide variety of improvements we made to attack surface, com...
