    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 discussed 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 Links mentioned in this episode: - Uniswap Exchange Protocol: https://bit.ly/2MVWl8i - Uniswap Whitepaper: https://bit.ly/2MTouN6 - Uniswap: Getting Started & Documentation: https://bit.ly/2FiCdqt - Unisocks Exchange: https://bit.ly/2IQYi0u - Distributed 2018: Presentation about Decentralized Exchanges by Arthur Hayes (BitMEX): https://bit.ly/2XpvIMI - Buidl Asia 2019 Conference in Seoul, Korea on July 22-23: https://bit.ly/2FipiF8 - HackAtom Seoul on July 19-21: https://bit.ly/2KXaGP7 Sponsors: - Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks - http://aka.ms/epicenter - Trail of Bits: Trust the team at the forefront of blockchain security research - https://trailofbits.com This episode is hosted by Brian Fabian Crain & Sunny Aggarwal.

    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 discussed 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 Links mentioned in this episode: - Secure Scuttlebutt website: http://bit.ly/2JU5YBX - Scuttlebutt Protocol Guide: http://bit.ly/2WIKTAu - Manyverse mobile client: http://bit.ly/2JVhZXN - Designing a Secret Handshake: AuthenticatedKey Exchange as a Capability System: http://bit.ly/2JVTABl - EfficientReconciliationandFlow ControlforAnti-Entropy Protocols: http://bit.ly/2JVg3yH - Scuttlebutt: an off-grid P2P social network that runs without servers and can fall back to sneakernet: http://bit.ly/2WBwPsD - The Nomad Who’s Exploding the Internet Into Pieces: http://bit.ly/2JVgbOH - Counter-Anti-Disintermediation: http://bit.ly/2JVgngT - “The Third Web” interview with Dominic Tarr: http://bit.ly/2WKojHJ - Dominic Tarr on Twitter: http://bit.ly/2JT5ZpX Sponsors: - Trail of Bits: Trust the team at the forefront of blockchain security research - https://trailofbits.com - Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks - http://aka.ms/epicenter This episode is hosted by Sebastien Couture & Friederike Ernst.

    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 discussed 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 Links mentioned in this episode: - Rainbow Network white paper: http://bit.ly/2wraOhs - Ivy Playground for Bitcoin: http://bit.ly/30P1WQI - Mirror project: http://bit.ly/2wp5awj - Paradigm: http://bit.ly/2HGkuLb - Dan Robinson on Medium: http://bit.ly/30NSooX - Dan Robinson on Twitter: http://bit.ly/2wqXV72 - Interchain Conversations Berlin event – use code EPICENTER for discounted tickets: http://bit.ly/2HGztVG - Cosmos Hackatom Berlin: http://bit.ly/30YQGkO Sponsors: - Cosmos: Join the most interoperable ecosystem of connected blockchains - http://cosmos.network/epicenter - Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks - http://aka.ms/epicenter This episode is hosted by Sebastien Couture & Sunny Aggarwal.

    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 discussed 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 - Jill’s podcast with Meltem Demirors, What Grinds my Gears Links mentioned in this episode: - Jill Carlson’s website: http://bit.ly/2HvTNJi - Open Money Initiative: http://bit.ly/2JXej74 - Petronomicon (blog post): http://bit.ly/2VIFC7x - Crypto Is Not An Asset Class (blog post): https://bit.ly/2VSkaBM - What Grinds my Gears podcast: https://apple.co/2VJyXtM - Jill Carlson on Medium: http://bit.ly/2VIFIMr - Jill Carlson on Twitter: http://bit.ly/2JWLEz5 Sponsors: - Cosmos: Join the most interoperable ecosystem of connected blockchains - http://cosmos.network/epicenter This episode is hosted by Sebastien Couture & Sunny Aggarwal.

    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 maintain high-availability, centralized data indexes which sit between the client and the blockchain. Thought user experience is greatly improved, the practice means most of the ecosystem relies on centralized infrastructure. We're joined by Yaniv Tal, Project Lead at The Graph. The project aims to create a scalable marketplace of robust and high-availability blockchain data indexes. Relying on the modern GraphQL data query language initially developed by Facebook, The Graph allows developers to make complex queries to a robust and high-availability data infrastructure. Launched as a hosted service earlier this year, The Graph plans to move to a decentralized model in the future. Topics discussed in this episode: - The vision of The Graph and why the team chose to work on this problem - The REST API client-server model in the Web 2.0 paradigm - The state of the Ethereum ecosystem and the challenges relating to data availability - How DApps work behind the scenes and their backend infrastructure - GraphQL as the evolution of the API model - How The Graph addresses the issue of data querying and availability - Their hosted services and plans to move to a hybrid model - How The Graph addresses privacy and scalability - The incentive mechanisms and economics related to data integrity - Early applications and the project's near-term roadmap Links mentioned in this episode: - The Graph - A Query Protocol for Blockchains: http://bit.ly/2GqfxFK - The Graph on Medium: http://bit.ly/2Gq5EYD - Browse and Explore Subgraphs: http://bit.ly/2Gq63KD - Graph Docs: http://bit.ly/2GqkPRL - GraphQL Will Power the Decentralized Web: http://bit.ly/2GrYgfp - The Graph’s Research and Specifications are Now Open Source: http://bit.ly/2Gq6d4H - Our Investment In The Graph - Multicoin Capital: http://bit.ly/2Gpd7aj - GraphQL: http://bit.ly/2GpdgdR - Yaniv Tal on Twitter: http://bit.ly/2GpdrG3 Sponsors: - Cosmos: Join the most interoperable ecosystem of connected blockchains - http://cosmos.network/epicenter This episode is hosted by Brian Fabian Crain & Sebastien Couture.

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 incentivized to curate their content according to social consensus. We're joined by Simon de la Rouviere, an independent researcher and blogger. Previously, Simon was one of the first employees at ConsenSys and founded Ujo Music. He also contributed to the ERC20 token specification and has written about blockchain and token economics since 2014.

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 decentralized marketplace where people come together to buy and sell products and services anonymously with crypto. Its polished interface and reputation system gives users a similar experience to that of using eBay, but without fees or the risk of censorship. Topics discussed in this episode: - Brian and Washington's respective backgrounds - The origins of OpenBazaar as the Dark Market project - The history and evolution of OpenBazaar since their last appearance on episode 67 - How OpenBazaar managed to survive all these years and how the vision has evolved over time - Who uses the platform and to what ends - How it compares to traditional dark markets like The Silk Road - OpenBazaar's position on deplatforming and how it responds to pressure to censor content - How OpenBazaar works under the hood as a collection of decentralized technologies - The company's business model and future plans Links mentioned in this episode: - OpenBazaar website: https://bit.ly/1NkXJex - Dark Market project on GitHub: https://bit.ly/2Fe9Jxi - Episode 67 of Epicenter with Brian Hoffman: http://epicenter.tv/067 - Trust is Risk: https://bit.ly/2JnqhIo - Brian Hoffman, Twitter: https://bit.ly/2TX8qfC - Washington Sanchez, Twitter: https://bit.ly/2fqmRVT Sponsors: - Cosmos: Join the most interoperable ecosystem of connected blockchains - http://cosmos.network/epicenter This episode is also available on : - Epicenter.tv: https://epicenter.tv/279 - YouTube: http://youtu.be/_2NbCJu2ehg - Soundcloud: http://soundcloud.com/epicenterbitcoin/eb-279 Watch or listen, Epicenter is available wherever podcasts are distributed.

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 working on an implementation he called Grin. Grin slowly began to draw attention from the Bitcoin community and got a lot of traction. We join Michael Cordner (Yeastplume) and Daniel Lehnberg, two of the core developers of the Grin blockchain. In this episode we discuss some topics around Grin's cypherpunk origins, privacy and scalability features, no-premine fair start, and interesting monetary policy. Topics discussed in this episode: - Origins of the Mimblewimble proposal and the prior work it draws upon - Andrew Poelstra's contributions to improving and fixing the original proposal - Scalability and fast sync times achieved through mimblewimble's UTXO set compression - How UTXO compression when combined with the Dandellion p2p protocol can increase privacy - Changes in user experience from Bitcoin to Mimblewimble - Beginning of the Grin project as an implementation of the Mimblewimble protocol - Comparision to BEAM, a competing Mimblewimble implementation - Innovating on fair Proof of Work through dual Cuckoo Cycle - Grin's Monetary Policy and the Mining Fair Start Links mentioned in this episode: - MimbleWimble Origin: https://bit.ly/2CsXiPe - Andrew Poelstra's Improved Paper: https://bit.ly/2Bk5OLQ - Introduction to Grin: http://bit.ly/2SZeOyn - Grin for Bitcoiners: https://bit.ly/2nNnk6y - Grin Newsletter: https://bit.ly/2CiAuzZ - Michael Cordner on Twitter: https://bit.ly/2XQ0FqW - Daniel Lehnberg on Twitter: https://bit.ly/2HrehmI Sponsors: - Azure: Deploy enterprise-ready consortium blockchain networks that scale in just a few clicks - http://aka.ms/epicenter This episode is also available on : - Epicenter.tv: https://epicenter.tv/278 - YouTube: http://youtu.be/ptNoUbnGSVc - Soundcloud: http://soundcloud.com/epicenterbitcoin/eb-278 Watch or listen, Epicenter is available wherever podcasts are distributed.

Amaury first got started with Bitcoin in 2010 and closely followed the Bitcoin block size debate as it progressed through the early years of Bitcoin. Predicting the eventual failure of SegWit2x, Amaury was part of the original team that helped coordinate the Bitcoin Cash hard fork, timing it with the activation of SegWit on the main Bitcoin blockchain. We discuss with Amaury the roadmap for Bitcoin Cash, especially with regards to their approach to scalability. We cover many of the novel features the Bitcoin Cash development teams are innovating on such as Canonical Transaction Ordering and Avalanche Pre-Consensus, as well as cover some of the more juicy drama that plagued the Bitcoin Cash community in late 2018, leading to split off of Bitcoin SV.

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 Blockstream, where he works on their LN client. We discussed the history and progression of the LN and what remains on the road to scaling Bitcoin. Topics discussed in this episode: - How Christian ended up writing the world’s first PhD on Bitcoin - The vision of the Lightning Network - How the Lightning Network evolved in the last 4 years - Approaching the 1.0 specification - The current state of the network - Why centralization concerns around hubs are often misguided - eltoo and the future of lightning network - The case against other chains being better layer 1 networks than Bitcoin Links mentioned in this episode: - Lightning Network Whitepaper: https://bit.ly/1f9uHPa - Christian Decker - Scaling Bitcoin with Duplex Micropayment Channels: https://bit.ly/2GtW1sy - Joseph Poon & Tadge Dryja - Scalability and the Lightning Network: https://bit.ly/2hmRAVh - Blockstream - Lightning Network: https://bit.ly/2DfDeOh - A Simplified Update Mechanism for Lightning and Off-Chain Contracts: https://bit.ly/2RIXBZu - Lightning Network Specifications on Github: https://bit.ly/2IcdNmH Sponsors: - Toptal: Simplify your hiring process & access the best blockchain talent
