Bitcoin Q&A: Is Bitcoin development centralised?
Bitcoin development is becoming more decentralised. It began with Satoshi as the sole developer and miner; now there are hundreds of Bitcoin developers and thousands of miners across the world. This system is self-correcting. If we become too centralised, we are more vulnerable to attack. If Bitcoin is attacked, it will either be forced to decentralise or die, and we can always build it again.
This is part of a talk which took place on December 6th, 2016, at the Bitcoin Cologne meetup in Köln, Germany: https://www.meetup.com/Bitcoin-Cologne/events/232687726/

CAN S
can-stablecoins-survive-(sob-episode
Join hosts Adam B. Levine and Stephanie Murphy along with special guest Josh Scigala, CEO of Vaultoro, for a wide-ranging exploration of the growing asset class of "Stablecoins."
On this episode of Speaking of Bitcoin we discuss:
The possibility of central banks or regulators banning private 1:1 stablecoins.
The challenges faced by early, decentralized, overcollateralized stablecoins.
How negative interest rates will drive 1:1 stablecoins into fractional reserve.
The potential weaponization of unlimited money printing to take control of limited resources.
The scenario where governments freeze bank accounts connected to 1:1 backed coins in an attempt to destroy the wider crypto economy.
The Potential for mismanagement of funds by 1:1 companies and threat of a Lehman brothers 2.0
The shrinking but still dangerous dearth of transparency within the biggest stablecoin balance sheets
Why regulators can't seem to keep up with real solutions
Why Josh believes decentralised stablecoins present a better set of tradeoffs.

what-development-challenges-are-there
While the Lightning Network runs as a second layer to Bitcoin, it's development is different and allows for much more experimentation. Lightning can be built without the strict adherence to and concern with consensus rules required for Bitcoin development. Lightning developers instead work with a set of standards called B.O.L.T. In this video Andreas explains a bit about Lightning development and walks through some current challenges.
0:00 Development challenges for the Lighting Network
0:19 What is BOLT (Basis of Lightning Technology)
1:15 Cool new Lightning features are being built
2:01 Lightning Network challenges
3:57 Solutions and trade-offs for Lightning Network development

CAN S
can-someone-guess-my-crypto-private-key
Can't someone guess my bitcoin, ether, or other crypto private key? People ask this question all the time! Maybe you've even asked it yourself. Most answers are something like, "No, they can't". But how do I know they can't? Why is it so hard to guess a crypto private key? Watch this video where Andreas explains, in plain terms, why it's basically impossible for someone to just guess the private key to unlock your bitcoin, ethereum, or other cryptocurrency.
Chapters
0:00 Introduction -- What is Down the Rabbit Hole?
1:22 Can someone guess my bitcoin, ether, or other crypto asset private key?
2:28 What is a crypto private key?
2:58 A crypto private key is a long number but how long is it exactly?
3:50 What is 2 to the 256?
5:00 Unfathomably big numbers!
8:00 Molecules and sand!
13:00 Eddington
Private keys that control cryptocurrencies are taken from a large number set. A really large number set. So large, in fact, that it's almost impossible for most of us to understand how large it is. Which makes it hard for us to understand why someone can't just guess our private key. In this edition of Down the Rabbit Hole Andreas asks himself how a human can visualize the incredible unlikeliness that someone will be able to guess your private key as he combines three of his favorite topics, cryptocurrency, physics, and astronomy! How many grains of sand are there on a beach? How about on planet Earth? How many molecules of silica in the Milky Way? How many crypto private keys are there?
This question is from the October Open Topic Livestream Q&A, which took place on October 24th, 2020. Watch the entire video here: https://youtu.be/maS5xUMZo7E.

bitcoin-q-a-why-has-mining-centralised
Centralized payments are a powerful force for centralization of the web, creating platforms for content and services that are centralized around a payment processor/aggregator. What happens when payments themselves become decentralized? The nexus of centralization dissolves and the content platforms can become decentralized too. In this talk presented at the Los Angeles Bitcoin Meetup, Andreas examines the impact of payments and the re-decentralization of the web.
Keywords/phrases: Mining centralisation is the result of the hash rate's rapid acceleration, going from CPU mining to ASIC mining to catch up with Moore's Law. There a reasons mining has centralised in China. They have experienced enormous growth in electricity generation in the last twenty years but with poor distribution networks, so there is a lot of extra capacity that is wasted. If you have an excess of electricity generation, you can either turn it back off (which can take several hours) or you make money mining during the lull in demand. One Chinese mining farm partnered with a hydroelectric plant in a tiny village. Bitcoin is a battery, it is an energy storage mechanism. The current incentives are to keep mining in China. There's a disparity between political power and electrical power. This represents the best of entrepreneurial capitalism in a country that desperately needs it, which we should applaud them.

bitcoin-q-a-multi-signature-and
What happens when wallets (personal or at an exchange) are hacked? What is "sweeping" with regards to private keys? After a hack, is it possible to track the stolen bitcoin and identify the hacker? How do you keep bitcoin safe in a group / corporate environment? Is it possible to create a multi-signature setup with Trezor and Electrum? Could passphrases be brute-forced? What is happening with browser extension deprecation?
You will have to evaluate which tools are the best based on the amount of cryptocurrency you own, your circumstances, and your threat model.
