Hayden Adams: Uniswap – An Automated Decentralized Exchange for Ethereum
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 participants in the protocol and the importance of decentralized exchanges for the blockchain space.
Topics covered in this episode:
How Hayden's exploratory project to learn smart contract development took off and became Uniswap
How Uniswap works and its different participants
The advantage of an automated exchange instead of using order books
The role of liquidity providers in Uniswap
Feedback loops that can make Uniswap markets popular or collapse
The challenging economics of liquidity shares
Addressing Arthur Hayes' criticism of decentralized exchanges
Why Uniswap didn't create a tokeneconomic monetization model

Dominic Tarr: Secure Scuttlebutt – The “Localized” but Distributed Social Network
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 possibly encrypted for a friend's key to decrypt. When users meet, the system syncs their local databases using a gossip protocol and replicates the data. Encrypted data is transported from peer, to peer, to peer (or friends of friends) until it reaches its intended recipient. User may also optionally rely on public servers to sync data over the internet.
Topics covered in this episode:
Daniels background and life living on a boat off the coast of New Zealand
How being at sea gave him the idea for Secure Scuttlebutt
What is Secure Scuttlebutt and what are the goals of the project
The issues with centralization and redefining decentralization as a positive statement
The notion that the technological singularity only serves the goals of centralized power
How SSB stores information and how posts get propagates from between friends, and friends of friends
How the network leverages “Pub” servers to sync data over the internet
Usage of the platform and the communities which thrive there
The cost of spam and how users protect against DDoS attacks
The project’s funding and roadmap

Dan Robinson: Rainbow Network – Off-Chain Synthetics Exchange or “Multicolored Lightning”
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 complete a transaction is an on-chain payment channel collateralized by a single asset. Though it is still at the idea stage and has yet to be implemented, the Rainbow Network could have applications in prediction market and as a new type of decentralized exchange.
Topics covered in this episode:
Dan’s background as a securities layer turned coder
His trajectory from working at Chain, to spending some time at Stellar, to joining Paradigm Fund
His involvement in the development of the Plasma Cash and Plasma Debit protocols
Thoughts and criticisms of using HTLC’s in Lightning
What is the idea behind Rainbow Network and how to understand it in the context of Lightning
What are synthetics assets and the ability to trade multiple assets in a single payment channel
The ability to have leverage in a Rainbow channel trade
Next steps in research and implementation
Dan’s contribution to the Ivey “smart contract” language for Bitcoin

Jill Carlson: Open Money Initiative – Free Access to Finance as a Human Right
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 at Chain and Tezos, Jill has been writing about the cryptocurrency industry for several years. In 2016 she published a paper titled “Cryptocurrency and Capital Controls” which observes the use of Bitcoin in Argentina. Recently, she co-founded the Open Money Initiative, a research organization which looks into how people use money in closed economies. Their initial focus is on Venezuela where years of economic downturn and strict currency controls have created a humanitarian crisis which has political repercussions well beyond the country’s borders.
Topics covered in this episode:
Jill’s beginning working at Goldman Sachs in the Latin America market
Her journey from trading bonds to entering crypto space working at Chain
A brief history of Venezuela leading up to the current situation
What it’s like to experience hyperinflation
The Open Money Initiative and the organization’s goals
How cryptocurrency and specifically Bitcoin is used in Venezuela
The political motivations behind the Open Money Initiative
The story behind Venezuela’s Petro currency
