The Promise of Bitcoin: An Interview With Andreas M. Antonopoulos

My recent interview with Andreas M. Antonopoulos, information security expert and tech-entrepreneur, and the author of “Mastering Bitcoin”. 

EXTRACT:

2. Bitcoin is simultaneously a currency, a financial asset, and a technology protocol. Underlying bitcoin is the blockchain, a distributed public ledger. For people who are not intimately familiar with either bitcoin or blockchain, could you briefly explain what these technologies consist of?

The blockchain is a distributed database. The magic of bitcoin comes from sharing control over that distributed database through a consensus mechanism called “Proof of Work”. This ensures that no one is in control of bitcoin and that it operates based on predictable rules.

Entropy calculation to help understand societal change

Grantham Centre for Sustainable Futures, The University of Sheffield

A missing ingredient in our understanding of human influence on global environmental change is the quantitative measure of the energy interactions of societies operating under varied technological and geographical conditions. This project seeks to employ the archaeological and historical data for the comparative investigation of energy use in different societies.

The project lies at the interfaces between physics, archaeology and ecology and it will be addressed by developing models to calculate entropy generation rates within the case study systems. Entropy generation (as opposed to energy use) allows the “quality” or “usefulness” of different energy resources to be measured. Learn more.

Tiny Villages: Horizontally Scaling Society

Cloud computing is about horizontally (as opposed to vertically) scaling systems. Instead of building one super-powerful server, you create many inexpensive servers that each contain a small part of the system. There are multiple advantages to “scaling out” rather than “scaling up”, such as incrementally improved capacity with little or no downtime and less expensive, more maintainable servers.
