The concept of centralization from the perspective of a 70 year old Chinese Dama – “Centralization is that the money you think belongs to you, is actually in somebody else’s pockets.”
The Future Potential of the Internet and the Blockchain
Alex Mashinsky likens the internet and the blockchain to floors in the same building, with one having to be built before the other, and how currently the blockchain floor needs more time to reach it’s full potential.

What is a Blockchain? & How does Blockchain Technology Work? | Bitpanda Academy Lesson 3
Blockchain technology is essential for Bitcoin, but what is a Blockchain? And how does blockchain work? As a decentralised, tamper-proof database a blockchain has many applications – Bitcoin is only one of them. Watch the full video and by the end you will not only know what a blockchain is and how blockchains work, but also you will know more about what runs the blockchain and blockchains in combination with cryptocurrency. Basically, this is everything about blockchain explained in one video.
What are Smart Contracts in Blockchain, Importance & How Smart Contracts Work
Whenever someone buys a house, begins a new job, or purchases a candy bar, a contract is created between the two (or more) parties involved in the exchange. This contract defines and records the terms of the transaction, denoting the required actions of each participant.
Alone, a standard contract has no power to enforce the terms that it defines. Instead, a legal or governmental third party oversees the execution of a standard contract, ensuring that each party faithfully carries out their end of the bargain. If the terms are violated, the transacting parties must rely on this intermediary to rectify the broken contract.
However, thanks to recent advancements in distributed ledger technology, lawyers or other intermediaries are no longer required to oversee contracts. Using smart contracts, people can, for the first time, execute and enforce contracts without involving middlemen.
This video will give you a brief introduction to smart contracts along with how they actually work, empowering you to understand their fundamental concepts and how smart contracts will change the world.

The Hidden Reality of Quantum Physics With Sean Carroll
Sean Carroll, the American theoretical physicist who specializes in quantum mechanics, gravity and cosmology explains the hidden reality of the micro-world.
The fundamental theory in physics which describes the physical properties of nature at the scale of atoms and subatomic particles, is known as quantum mechanics. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Sean Carroll explains to us in simple turns the mysterious properties of quantum physics. He thinks that we should try to understand quantum mechanics even though prominent physicists like Richard Feynman thought no one can understand quantum mechanics.
Quantum mechanics arose gradually from theories to explain observations which could not be reconciled with classical physics, such as Max Planck’s solution in 1900 to the black-body radiation problem.
Sean Carroll mentions how predictions of quantum mechanics have been verified experimentally to an extremely high degree of accuracy.
He also explains the wave function collapse of quantum mechanics. Another spooky aspect in quantum mechanics is when quantum systems interact with each other and the result can be the creation of quantum entanglement: their properties become so intertwined that a description of the whole solely in terms of the individual parts is no longer possible.
Contrary to popular belief, entanglement does not allow sending signals faster than light.
Quantum mechanics is perhaps the most successful theory ever formulated. For almost a century, experimenters have subjected it to rigorous tests, none of which called its foundations into question. It is truly one of the major triumphs in modern physics.
