[Bitcoin Munich] Next Meetup: Thursday, Dec 22nd - Paper Wallets Workshop



https://www.meetup.com/Bitcoin-Munich/events/233919372/

Did you know you can print your bitcoins on paper and store them safely offline that way? Also holiday season is near, so we'll have an introduction talk and workshop about paper wallets, which make an original and unusual Christmas gift as well.




Apart from that, far beyond the use in Bitcoin and crypto-currencies, the concept of private and public keys, as depicted on such a paper wallet, may become more and more pervasive in the future in general. Passwords seem to be unsafe, as users forget them or pick too easy ones. And no matter what certain big hardware and OS manufacturers try to tell you, biometric identification like face or fingerprint recognition is unsafe as well and can easily be spoofed, as often demonstrated by ethical hackers.

So we'll take a look how secure (while hopefully still easy) identification and authentication may look in the future of a blockchain world. Maybe personal crypto-key management can and will some day become an intuitive habit in everyday life, just like we're used to handle our physical keys.

Target audience: Beginners

You're encouraged to bring your tablets or notebooks for this hands-on session! You should already own some bitcoins (or fractions), and have a wallet installed, e.g. Electrum.

Timetable:

19:00 Doors open, get-together, food + drinks

19:30 Bitcoin & Blockchain news roundup

20:00 Rupert Zinnecker: Paper Wallets for Crypto-Currencies
  • What are crypto-currencies?
  • How do I manage my crypto-currency units? ⇒ Wallets, especially paper wallets
  • Why do paper wallets work? ⇒ Blockchain technology
  • The paperwallet.bit website
  • Paper wallets as crypto cash, is that possible?
20:30 Workshop: Try it yourselves! And/or drinks, snacks, get-together. Open end!

You're very welcome to bring little things (cookies, tea-light candles, etc) to contribute to an xmas party atmosphere. Maybe leave a comment or contact one of the organizers so that we can better coordinate initiatives in this direction! Thank you!

Why P2P Software Is So Important ?



Obrázek/fotografie
" #Decentralization is the idea of the #internet! Each computer, each node is - or last should be - equal. This ist the Basic idea of independence, full control over your data and no control through others. Sharing this data makes it even more robust against #censorship, failures and #takedown. To establish such a net of #freedom we need more and better decentralized software. I think #ZeroNet could be another building block of that idea of a free internet! http://zeronet.io/ #freedata "

Post-Capitalism: Rise of the Collaborative Commons

As the disruptive capacities of technological innovations continue to advance at an exponential rate, it is increasingly clear that the capitalist economic model is unable to effectively manage resources and distribute wealth under the conditions of sustainable abundance now being brought forth. Vast increases in productivity and efficiency will be realized in the years ahead through an integrated network of smart-products (termed the Internet of Things, or IoT), accessible renewable energy harvesting technologies, energy sharing across a distributed smart-grid, the decentralization of manufacturing through 3D printing, open online education, the decentralization of finance, legal contracts and governance through Blockchain applications, and the progressive automation of the workforce.

Just as John Maynard Keynes prophesized nearly a century ago, “a point may soon be reached, much sooner perhaps than we are all of us aware of, when these [economic]needs are satisfied in the sense that we prefer to devote our further energies to non-economic purposes.” [1]Keynes foresaw such an economic state of abundance coming about through, what he first termed, technological unemployment which, he stated, “ [we]will hear a great deal in the years to come;” the ultimate implication being “that mankind is solving its economic problem.” [2]Keynes looked expectantly to a future in which machines had progressed to the point of providing an abundance of freely available goods and services to humanity — liberating people around the world from menial labor, debt and servitude for the first time.

Ironically, the operating principles of the capitalist marketplace are bringing us ever closer to this very state, while simultaneously the relevance of the competitive market is progressively undermined by the same emerging paradigm. Capitalist logic dictates that the entrepreneurial spirit of a competitive market will continually drive productivity increases and marginal cost decreases. Marginal cost — the cost of producing additional units of product — is the focus, as this is where entrepreneurs and businesses make their profits in a market-exchange economy (at the margin); and when marginal cost approaches zero, so too does profit. The effects of near zero marginal cost can already be seen wreaking havoc across several media industries such as entertainment, communications and publishing, as more and more content continues to be shared and made freely available across digital, collaborative networks.
