In Episode 49 of Hidden Forces, Demetri Kofinas speaks with Vitalik Buterin and Vlad Zamfir about the future roadmap for Ethereum.
If contracts are the foundation of modern civilization, then our record systems are the infrastructure that keep this foundation from falling apart. These features allow our society to establish and verify identities; give value to goods and services; create and enforce laws; govern interactions between individuals, organizations, and nations — in short, they secure our social, economic, and political policies and allow us to maintain the social order.
But there is a problem with these systems, and they are beginning to buckle and crack.
The information age vastly accelerated the pace of society, allowing individuals to dramatically expand their circles of influence. People can now exchange goods and services (or even enter into contracts) with strangers on the other side of the globe instantaneously. Government agencies and international organizations can maximize processes by storing and retrieving information online. However, these processes are fraught with challenges.
Without the presence of intermediaries, digital transactions have thus far been impossible to verify or enforce. Mediators and middlemen provide accountability on the one hand, in return for higher centralization on the other. This centralization creates opportunities for companies like Facebook and Google to make billions of dollars mining and selling our data. It also presents lucrative opportunities for malicious actors looking to capitalize on our insecure digital infrastructure. The digital records kept by banks and government institutions are frequently the subject of cyber attacks, putting this same data at risk.
As the first decentralized digital currency, bitcoin promised to solve some of these issues; however, bitcoin's use cases have remained limited to a very narrow set of financial transactions. In response, Vitalik Buterin created Ethereum. In his 2012 white paper, Vitalik outlined an ambitious vision of the future — one that would endeavor to solve the problems associated with our contracts, transactions, and records by creating a new, decentralized layer for data processing and computation on which society could run.
Whereas Bitcoin’s aim was to erect a platform for unmediated digital payments, the goal of Ethereum’s blockchain-based architecture is to entirely dismantle traditional power structures and methods of control. It attempts this by allowing decentralization to saturate all levels of society through the use of an open, distributed ledger that records transactions between parties in a more trusted way way.
In Ethereum blockchain, contracts are embedded within digital code, which are stored in transparent, shared databases. In theory, it makes intermediaries like bankers and lawyers unnecessary and allows individuals to transact freely. Ethereum increase access, transparency, and accountability, without relying on third-parties to secure the ledger.
Ethereum blockchain has opened the door to a new type of economy, yet challenges remain — specifically, challenges to scale.
The most prominent of these scaling challenges has been transaction throughput. Currently, the Ethereum network can process no more than fifteen transactions per second (TPS). This is major barrier to widespread adoption and it has prevented the blockchain from being able to support the type of network traffic that would result from the popular use of any decentralized application (dApp). In response, Vitalik, Vlad, and other key members of the Ethereum have put forward a roadmap for scaling the Ethereum network.
From sharding to Plasma to Casper, in this week’s episode, host Demetri Kofinas is joined by Vlad Zamfir, one of is the world’s leading Ethereum researchers, and Vitalik Buterin to discuss the future of Ethereum, the problems it faces on the path to widespread adoption, and the solutions that promise to carry us into a decentralized digital age.

In Episode 48 of Hidden Forces, Demetri Kofinas speaks with Annie Duke and about how we can make smart decisions and ensure our long-term success.
We make millions of decisions over the course of our lives. Most of these seem to be small and of little consequence, and so we make our choices and act with little care or thought. Other decisions require more care and consideration, as their significance will, for better or worse, have a lasting impact on our life: What job offer to accept, what life partner to choose, how to invest in retirement.
When faced with these truly important decisions, many people become crippled by their fear and doubt. What if it’s a bad prediction? What if I am missing information, and so my choice is wrong? Often, such fears have a cascade effect, they trickle down and impact our ability to make even the smallest judgement, leaving us paralyzed.
However, there is a way to increase the likelihood that we’re making a sure bet.
According to Annie Duke, a World Series of Poker champion and the author of Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts, regardless of whether the choice is small or large, the key to solid decision-making rests in our ability to shift our thinking from a need for absolute certainty to “a goal of accurately assessing what you know and what you don't.” In other words, people need to look at every decision as though it were a bet.
Ultimately, Duke argues that by adopting this way of thinking — by assessing how sure we are of something, tracing the possible outcomes, and analyzing the odds of failure — we can ensure long-term success for ourselves, our loved ones, and our business partners.
Calling on her degrees in behavioral and cognitive psychology, and her years of experience in professional poker, throughout the episode, Duke speaks with host Demetri Kofinas about how we can eliminate fear and unproductive emotions from our decision-making processes, embrace uncertainty, and make better decisions.

In Episode 47 of Hidden Forces, Demetri Kofinas speaks with Jimmy Soni about the father of Information Theory, Claude Shannon, and Shannon’s foundational work, A Mathematical Theory of Communication.
The 20th century is known as the information age, and for a good reason. It is a period that is dominated by knowledge and data. It’s an era in which the economy is no longer driven by traditional industries — such as construction, manufacturing, or agriculture — but by advanced information technologies that store, retrieve, transmit, and manipulate data.
This revolution finds its roots in Information Theory. And remarkably, it is a theory that was developed by one man: Claude Shannon.
Before Shannon, society had a rather immature understanding of what information was. Information was understood as something immaterial and intangible. It was not seen as something that could be touched or manipulated. It was assumed that the only way to send information (intelligence, as it was then referred to) across a greater distance was to “boost” the signal by using more power. This was a notoriously imperfect system, as it increased the amount of “noise” that was received and made the message more difficult to discern.
In his foundational work, A Mathematical Theory of Communication, Shannon solved this issue and presented a completely new way of understanding information. He showed that information isn’t insubstantial, but something that we can measure and manipulate — something that has physical characteristics and can be quantified. Shannon also created a diagram which showed that all information has certain, set components — such as a source, a transmitter, a recipient, and so on. As such, not only did he show that information is something that can be made material, through his work, Shannon proved that all information (be it a radio signal, a photo, or a song) can be governed through a set of common laws.
In short, he turned information into something that can be computed and reliably transmitted, laying the foundation for the digital revolution.

In Episode 46 of Hidden Forces, Demetri Kofinas speaks with Brian Keating, astrophysicist and author of Losing the Nobel Prize: A Story of Cosmology, Ambition, and the Perils of Science's Highest Honor.
When we think about competition, we don’t typically think about scientists. Instead of seeing these individuals as adversaries competing for fickle prizes or glory, we see them as impartial explorers of the cosmos. We see them as the selfless gatekeepers of knowledge.
This view, as we are coming to learn, is more than a little askew.
The darker sides of science — the prejudices and egos and dubious incentives — are realities that we are forced to face almost as soon as we start investigating what it is that drives scientists in their pursuits.
And they are realities that Brian Keating knows all too well.
Keating is an astrophysicist at UC San Diego's Center for Astrophysics and Space Sciences. He is also credited as being the driving force behind BICEP2, the most powerful cosmology telescope ever made. BICEP2 was tasked with answering some of the biggest questions in physics, such as how our cosmos came to be and what the universe was like at the beginning of time. Specifically, the telescope was created to detect the unique B-mode polarization signature of the cosmic microwave background (CMB), a byproduct of the cosmos’ first moments of expansion.
For a time, Keating and his team believed they had detected this signature. The work almost won Keating the Nobel Prize in Physics. Almost.
In this episode, Keating joins host Demetri Kofinas to walk us through the history of experimental cosmology and trace its course to modern science. He starts with an examination of the early geocentric models of the universe and shows how the scientific revolution, and the introduction of empiricism, altered the course of history and set us on the path to modern physics. The episode culminates with a discussion of what it is that drives scientists in their pursuits. From wealth to fame, from a genuine desire to understand the origins of the cosmos to an egotistical desire to wage war on religion, Keating outlines some of the most remarkable discoveries in physics and how biases and incentives are slowing innovation and shredding the fabric of modern science.
