The concept of a decentralized exchange has been a holy grail in the cryptocurrency space for many years. Many attempts have been made, but most decentralized exchanges suffered from central points of failure, poor user experience and little liquidity. Launched during Ethereum's DevCon 2018, Uniswap is one of the first fully decentralized exchanges and managed to become the leading DEX very fast. We were joined by Uniswap Founder Hayden Adams to discuss Uniswap's unique model, the different part...

We're joined by Tal Moran, Chief Scientist at Spacemesh. This new consensus protocol is designed to run on home desktop PCs, filling free space on users' hard drives to create a Proof of Space-Time. The goal of this new blockchain protocol is to solve the issues with Proof of Work and Proof of Stake, that is, energy inefficiency on the one hand, and possible centralized plutarchy of rich validators on the other. Topics covered in this episode: Tal's background as an academic and researcher The p...

We’re joined by Dominic Tarr, a sailor, and the Founder of Secure Scuttlebutt. This curiously named project has a fascinating approach to creating a truly distributed social network. One might even say that Secure Scuttlebutt is “localized” as it gracefully degrades to Sneakernet, something few blockchain projects can claim. In actuality, the SSB protocol isn’t a blockchain in the traditional sense – each user’s feed acts as a sort of localized chain of posts, signed by their public key, and pos...

We’re joined by Dan Robinson, a research partner at Paradigm, and the author the “Rainbow Network” paper. The paper describes an off-chain decentralized synthetics exchange which leverages payment channels. The Rainbow Network is based on the idea that “rainbows are basically just multicolored lightning,” borrowing from the concepts used in the Lightning Network. The protocol relies on trusted oracles and allows participants to trade any type of liquid asset off-chain. All that is necessary to c...

A common meme in the cryptocurrency space is that it has the potential to help people in countries where only the rich and powerful access to global financial markets. But ten years after the Bitcoin white paper was released, just how many “unbanked” people has cryptocurrency helped? Some see crypto as a tool to empower vulnerable populations in places where hyperinflation and strict capital controls make day-to-day survival a nearly impossible challenge. We’re joined by Jill Carlson. Previously...

The Ethereum Foundation has played a crucial role in the evolution of the blockchain ecosystem. They pioneered the Swiss foundation structure and ran one of the first token sales. They played a key role in developing the second-most valuable blockchain network and still play a key role in funding research and steering the future of Ethereum. At the same time, it has been frequently criticized for a lack of transparency, being too slow in funding development and poor financial risk management. Ex...

We're joined by Mike Pieciak, President of the NASAA. Not to be confused with the space agency, the North American Securities Administrators Association brings together state, provincial, and federal securities regulators in Canada, Mexico, and the United States. This relatively unknown organization helps align the financial regulation policies of over 50 agencies across North America and coordinates enforcement action in cross-border cases. In 2018, the NASAA launched “Operation Cryptosweep” in...

At the core of the Web 2.0 stack lies the REST API. It's the fiber which allows frontend applications to communicate with their backend counterparts, as well as the services on which they depend. But the API model is highly constrained and inflexible. The API is divorced from the data model, which creates a number of restrictions and inefficiencies. Most blockchain clients, including Geth, Parity and Bitcoin Core, use a JSON-RPC model which suffers from similar issues. Several Ethereum DApps mai...

Human beings have a penchant for creating lists. We make lists for things like the top music artists at any given time, the best restaurants in the world, companies which people can trust, and the most wanted criminals. Lists take many forms. They can be maintained by a single authority, or curated by a crowd. But almost always, they remain in the custody of a central party. Token Curated Lists propose a model by which a) the content of lists are decentralized, and b) contributors are incentiviz...

The shipping container brought standardization to the way we move goods around the world. Similarly, TCP/IP packets normalized how information transits over computer networks. Today, blockchains remain siloed ecosystems and interoperability is practically non-existent. A new wave of third-generation blockchain protocols aims to change this. In this new paradigm, blockchains communicate natively and value moves seamlessly from one network to another. One of those projects is Cosmos. We’re joined ...

Dogecoin was born from the association of two browser tabs: one was an article about the popularity of the doge meme, and the other, CoinMarketCap. The idea quickly gained traction on Twitter, and before long, a new cryptocurrency was born. Dogecoin gained adoption as a tipping currency, the community took part fundraising for charities and other causes, perhaps most notably sending the Jamaican bobsled team to the Sochi Winter Olympics. We’re joined by Jackson Palmer, co-creator of Dogecoin. Th...

In the early days of Bitcoin, much of the community’s focus was around payment and getting merchants to adopt cryptocurrencies. Although the technology and narratives have evolved, some projects continue to embrace that original vision of peer-to-peer business, where merchants and their customers interact directly, and if they so wish, anonymously. We’re joined by Brian Hoffman and Washington Sanchez of OpenBazaar. Since we last interviewed Brian in 2015, the project has grown to become a mature...

Three years ago, a mysterious txt file signed by a pseudonymous Tom Elvis Jedusor was dropped in the Bitcoin-Wizards IRC channel outlining a proposal called Mimblewimble. It proposed a novel way of combining many ideas from Bitcoin research in order to create a new blockchain protocol that will be highly scalable and increase privacy, while still using the same cryptographic assumptions as Bitcoin. A few months later this project was picked up by another pseudonymous individual who started worki...

Artificial Intelligence is often misunderstood. And much like blockchain, those who fiercely stand by the technology believe it will change the world for the better. Others fear the negative repercussions it could bring it and would rather see it disappear. We’re joined by Ben Goertzel. Ben’s interest in AI and robotics date back to his childhood and he has made these his life-long passion and work. He is the CEO of SingularityNET, a company building a marketplace for AIs which leverages blockch...

When the Lightning Network (LN) was conceived in 2015, it was quickly embraced by the Bitcoin community as the way to dramatically scale Bitcoin’s capacity. There was an expectation of LN being available quickly. Instead, development proceed more slowly in the background with different teams contributing to a standard specification. That spec is now almost ready and last year interest and early activity on the LN increased dramatically. We were joined by Christian Decker, a core engineer at Bloc...

The concept of DAOs has been captivating to many in the crypto space for years. When “The DAO” was created in 2016, in the few weeks of its existence and despite obvious flaws, it gather tremendous momentum and amassed 14% of the entire ether supply. Since then the technology has matured and Martin and Matan argue that the time for DAOs has finally arrived. We were joined by DAOstack Founder Matan Field and Gnosis Founder Martin Köppelmann. We talked about the decentralized exchange protocol Dut...

When token sales and ICOs took off in 2017, most projects chose to push ahead despite large regulatory risks. One of the few that went the other direction and put compliance first was CoinList. The platform made its debut by running the massive Filecoin token sales in which $205m was raised from accredited investors. CoinList also played a major role in popularizing the SAFT and creating tools to efficiently and legally raise in the US. We were joined by CoinList President and Co-founder Andy Br...

Lending is one core pillar of the economy, enabling one person or company to be entrepreneurial with someone else’s capital. However, in the traditional banking system processes in lending are often opaque and the barrier to entry into this market is high. The emergence of easy to use Decentralized Finance is one of the hallmarks of 2018: To date, DeFi has brought us crypto-collateralized stable coins, decentralized exchanges, tokenized credit default swaps, trustless derivatives, and decentrali...

Since the rise of digital currencies and cryptocurrencies, central banks are considering the role these new forms of money may play in our evolving digital economy. One of the ideas studied is the notion of a central bank digital currency. While people and companies can hold central bank liabilities in the form of cash, only licensed banks have access to digital cash accounts with central banks. We’re joined by David Andolfatto, VP of Research at the Federal Reserve Bank of St. Louis. David was ...

We enter dozens of trust relationships ever time we interact with the Web. Browsers, ISPs, DNS providers, cloud hosting companies, all the way down to the handful of people who control certificate root keys; we rely on the integrity of these intermediaries to serve reliable, and accurate information. The concentration of power by any one of these actors threatens to compromise the very foundational principles of the Web. Decentralized technologies, like Bitcoin, Ethereum, Tor, and IPFS seek to r...
