₿🛠️ Satoshi's 21 #004: Taproot 🥕

https://www.meetup.com/Bitcoin-Munich/events/271290157/

https://twitter.com/bitcoinmuc/status/1283838309983236096

Taproot is the name for a set of updates that will soon be activated in Bitcoin via a soft-fork.

Among other things and for a start, these updates will improve privacy and on-chain capacity by providing ways such that the available block space can be used more efficiently. Scripts can be more compact and reveal less information, and (with later additional updates) the inputs and outputs of transactions can be aggregated.

That means, true and actual on-chain scaling (i.e., not by just increasing the block size).

It is generally hoped that for example CoinJoin, which is a method to use Bitcoin in a more private way and a "many-users-to-many-users-in-one-transaction" format, should see more adoption simply because of the lower fees per user, as the available block space is used more efficiently than when all those users submitted many individual "normal" transactions as per usual.

This will be the case even more so with the Schnorr signature scheme, as "many-to-many" transactions can then be compacted by aggregating the involved public keys and signatures into one single so-called threshold public key and the corresponding threshold signature, making such an aggregated transaction look indistinguishable from a "normal" transaction, benefiting scalability and privacy even more. (This cross-input aggregation part is what's further down the roadmap though.)

Combined with MAST (Merkelized Abstract Syntax Tree), also rather complex scripts ("Smart Contracts") can be made to look indistinguishable from "normal" transactions.

This is our new in-depth, no-nonsense seminar series Satoshi's 21, which will take place every 21st of a month in various different locations (hackspace, co-working space, conference room, or similar), or online if circumstances so require.

We'll have one or more selected topics concerning Bitcoin's technology, security, ongoing development, economics, monetary theory, or its societal and political impact. Some preparation work might be required from participants in order to make the most out of the seminar.

Satoshi's 21 stands for:
- Every 21st of a month so that weekdays rotate
- 21 participants is the targeted and ideal working group size, but we could be more, we could be fewer
- And of course: honoring Bitcoin's monetary supply of 21 hundred trillion sats!

₿🗣️ Cryptocurrency Market Dynamics + The Liquid Sidechain

We will discuss the recent trends in the cryptocurrency sphere as well as the reason for exponential growth in the market. Since 2009, Bitcoin has shown various exponential growth patterns, but where does it come from? What are the metrics that we can use to identify patterns early on? Is it driven by institutions or by retail investors?

We will also learn about Liquid, the first production-ready sidechain for Bitcoin.

₿🛠️ Watching the Video Premiere "Outside the Golden Cage of Banking" + Debate

Let's come together and watch the video premiere of "Outside the Golden Cage of Banking" and have a debate about the future of Bitcoin.

Andreas M. Antonopoulos has asked us to publish the following:

> We are planning the Video Premiere and Live Chat for Saturday, September 21st, at 18:00 Munich time. We will send the link to you to share around 48 hrs prior to the event.
>
> Hold the date: Saturday, September 21st at 18:00 Munich Time.
>
> Join our team and Andreas M. Antonopoulos for the YouTube Video Premier of "Outside the Golden Cage of Banking", the keynote he delivered at the Bitcoin Munich Meetup in Munich in July [correction: June]. During the video premier, Andreas and some of our team will be live in the YouTube chat, engaging with you while we all watch the video together. At Andreas' last video premier, more than 700 people from all over the world chatted it up during the event - laughing, joking, asking questions, and generally having a good time watching a video with friends.
>

₿🗣️ Privacy and Scriptless Scripts

A lot of people have been wondering lately about the GDPR and privacy laws, and how all this might apply to blockchains, as the data contained in the transactions and "smart contracts" of an immutable blockchain is in most cases pretty personal and usually cannot be altered or removed.

There is a lot that can be debated about this complex topic in any desired broadness and depth, with plenty of material for several evenings, but tonight we're going to pick out certain aspects.

First we are going to learn if and how businesses and startups in the space are affected by these regulations already today, what they are doing about it, and what their stance about user privacy is in general.

Suffice to say and in any case, the individual's privacy on the technological level has actually and always been the goal of the movement that eventually led to the creation of Bitcoin.

So later in the evening we're going to look at how "smart" contracts, and the data required to run them, might look like in the future when a technique named "Scriptless Scripts" is applied. The scripts of this type are executed off-chain, and are merely *settled* on-chain.

So what does this mean? We're going to learn about the cryptographic toolbox and the mathematical building blocks for the future of programmable money and more, in a way that also laymen can gain insights and the ability to assess the practical implications and the impact on the use-cases they care about.

The timing is good because the first altcoins, called "Grin" and "Beam", which are based on the so-called "Mimblewimble" blockchain format, are about to launch these days. Besides being related to Scriptless Scripts, this format helps blockchains also to scale better, while improving privacy and fungibility. The implementation of these concepts into Bitcoin is on the roadmap, but it might still take a few years.

₿🗣️ Die verrückte Geschichte vom Aufstieg eines neuen Geldes

Wir freuen uns, Christoph Bergmann begrüßen zu dürfen, Betreiber des langjährigen, qualitativ hochwertigen BitcoinBlog.de.

Er wird sein neues und erstes Buch vorstellen, das sehr ausgewogen und selbst-reflektierend geschrieben ist, und wir werden verstärkt daraus die gesellschaftlichen Hintergründe von Bitcoin beleuchten und diskutieren.

Wir wollen somit auch eine Zielgruppe ansprechen, die sich womöglich erst seit kurzem für das Thema interessiert, (noch) nicht so tief mit den technischen Details vertraut sein muss, aber genauere Vorstellungen von der Materie gewinnen möchte.

₿🗣️ Crypto Hardware Wallets: New Trezor Model T + DIY with Arduino 

We'll have Vojtěch Černý and his team from SatoshiLabs this time, introducing their new "Trezor Model T" and giving us the opportunity to discuss everything about Crypto Hardware Wallets in general, and we'll have Stepan Snigirev giving a teaser about his current DIY project based on Arduino.

Target Audience: As every so often we'll try to structure the meetup so that we'll have two parts. The first part should be accessible for newcomers. A new hardware wallet for crypto-currencies will be presented, the purpose of such devices will be discussed, and their usage be demonstrated. After a break we'll dive deeper into specific details for enthusiasts and professionals who want to stick around longer, highlighting aspects like the hardware development process, security considerations, and much more.

Hardware wallets might not only be crypto-currency related, but also may play a role in the near future to enable managing our identities in a self-sovereign way. Our guests tonight come from the "Institute of Cryptoanarchy" after all, so we can also discuss some sociopolitical aspects if the audience so desires.

Hello everyone, let's finish the summer break with something new: a casual-but-constructive get-together in the Amphitheater in the Englischer Garten. The weather forecast promises still warm weather, and we have some leftover beverages (beers, mate, and other stuffs) that we can offer and share as long as stocks last.

We don't have an official program, but the idea for this format is to discuss a range of topics one at a time with the whole group. Whoever wants can also give an impromptu lightning talk (free-style, no equipment at the place; topic can be about the technology, about economics, about political perspectives, and similar educational content; no marketing or ICO promotion!).

⚡ Lightning Workshop: Incentivizing Mesh Networks + Be Your Own Fan with Matreon

The Lightning Network will continue to be one of the hottest topics in our space, so let's start a series of workshops.

Sjors Provoost, contributor to Bitcoin Core and c-lightning, and Jörg Hermsdorf from CONSERVE Blockchain-Service will instruct us today about setting up Lightning for specific use cases.

There can be never enough WiFi hotspots. Jörg will introduce his project in which he forked Freifunk. https://en.wikipedia.org/wiki/Freifunk

Freifunk is meant to be free as in speech as well as free as in beer, but maybe a lot more people will set up routers if they can earn a few bits of crypto-coins lightning-streamed from our wallets?

Sjors will demonstrate how to set up Matreon, a self-hosted platform to receive recurring donations. https://btcmanager.com/matreon-may-soon-reward-creators-via-bitcoins-lightning-network/

We will actively set up a full node and lightning on AWS, pay ourselves and then take the money out again.

Please have an installed Bitcoin Core node synchronized to testnet ready on your laptops! https://en.bitcoin.it/wiki/Running_Bitcoin

Target Audience: Strongly technical. Developers, advanced Bitcoin followers, or mesh network enthusiasts.
