Centrifuge is an open and permissionless protocol built on Polkadot and Ethereum that unlocks collateral for DeFi. Centrifuge allows for the tokenization of real world assets such as invoices, real estate, or goods, and puts them on the blockchain. This allows users to borrow against these assets from investors. Investors lend dai in exchange for an interest rate that depends on the borrower and the asset used as collateral.We were joined by Lucas Vogelsang, CEO & Centrifuge Co-founder, and Cassidy Daly, Token Design & Research at Centrifuge. They explained why they built the protocol and how it works, the first application built on top, Tinlake, its integration with other DeFi platforms such as Maker, and their vision for the future.Topics covered in this episode:How did Centrifuge come about and what is its visionWhat challenges do they face using real world assets as collateralHow users are protected against spam and fraudThe underwriter token modelWhat are the value limits on what can be borrowed?Some use cases of where Centrifuge can make the biggest impactWho are the lenders involved in the protocol?How the protocol works on a technical levelThe Centrifuge token - CFGAltair - the Kusama parachain on PolkadotWhat the integration of Tinlake assets in DeFi looks likeEpisode links:Centrifuge websiteTinlakeUnderstanding TinlakeCentrifuge on TwitterLucas on TwitterCassidy on TwitterSponsors:Exodus: Exodus the easy-to-use crypto wallet available on all platforms and supporting over 100 different assets. - https://exodus.com/epicenterSolana: Solana is the high performance blockchain supporting over 50k transactions per second to power the next generation of decentralized applications. - https://solana.com/epicenterParaSwap: ParaSwap’s state-of-the-art algorithm beats the market price across all major DEXs and brings you the most optimized swaps with the best prices, and lowest slippage - http://paraswap.io/epicenterThis episode is hosted by Brian Fabian Crain & Friederike Ernst.

Non-fungible tokens (NFTs) are tokens that we can use to represent ownership of unique items. They let us tokenize things like art, collectibles, even real estate. They can only have one official owner at a time and they're secured by the Ethereum blockchain. And they have taken the crypto space by storm is recent months. Showtime is a NFT social media network where creators & collectors showcase their digital art. It reads all marketplaces and instead of buying and selling, you can comment, share and like. It's been described as the Instagram for NFTs.We were joined by Alex Masmej, Co-founder and CEO of Showtime, to chat about why he got into NFTs and in particular crypto art, how Showtime works and its purpose, and the future of the platform.Topics covered in this episode:Alex's background and how he got into cryptoThe story behind the $ALEX tokenUncollateralized lending and why it's importantThe vision for ShowtimeAlex's views on the NFT crazeWhat is the open social graphWhy Alex chose to focus on crypto artHow Showtime compares to similar platforms like Opensea and ZoraThe Showtime business model, funding sources, and 5 year planEpisode links:ShowtimeShowtime on TwitterAlex on TwitterSponsors:ParaSwap: ParaSwap’s state-of-the-art algorithm beats the market price across all major DEXs and brings you the most optimized swaps with the best prices, and lowest slippage - http://paraswap.io/epicenter Solana: Solana is the high performance blockchain supporting over 50k transactions per second to power the next generation of decentralized applications. - https://solana.com/epicenterExodus: Exodus the easy-to-use crypto wallet available on all platforms and supporting over 100 different assets. - https://exodus.com/epicenterThis episode is hosted by Sebastien Couture & Sunny Aggarwal.

Ethereum will switch from Proof of Work (PoW) to Proof of Stake (PoS) likely already later this year in a much anticipated upgrade to Ethereum 2. The switch to PoS aims to make Ethereum both more secure and more sustainable by securing the network through Ether instead of mining. A second Eth2 update will address scaling through sharding at a later time.Danny Ryan, Researcher with Ethereum Foundation, has been a major driving force behind the Eth2 project. He joined us for a progress update and we chatted about how the protocol will work in its steady state, what has launched so far, what happens in The Merge, and how PoS will affect centralization tendencies.Topics covered in this episode:Danny's background and how he got into cryptoAn overview of Eth2 - Phase 0, Beacon ChainThe role of a validator and building blocksPenalties and rewards within the protocol including slashingWhat the epoch is and how it relates to finalityThe Proof-of-Stake mergeWhy Proof-of-Stake is favorable for security purposesWhat is the roadmap for sharding?Ethereum feesEpisode links:Ethereum CommunityEth R&D DiscordEthereum on GitHubEth ResearchEF on TwitterEF blogDanny on TwitterSponsors:Solana: Solana is the high performance blockchain supporting over 50k transactions per second to power the next generation of decentralized applications. - https://solana.com/epicenterExodus: Exodus the easy-to-use crypto wallet available on all platforms and supporting over 100 different assets. - https://exodus.com/epicenterParaSwap: ParaSwap’s state-of-the-art algorithm beats the market price across all major DEXs and brings you the most optimized swaps with the best prices, and lowest slippage - http://paraswap.io/epicenterThis episode is hosted by Friederike Ernst & Martin Köppelmann.

Curve is an Automated Market Maker (AMM) that lets users and other decentralized protocols exchange stablecoins (DAI to USDC for example) with low fees and low slippage. Unlike exchanges that match a buyer and a seller, users transact with the smart contract itself. By providing a flatter curve targeted for relatively stable pairs, Curve has established the lead position for these markets. Curve is also leveraging its own token CRV to incentivize long-term adoption of the protocol and decentralize control of governance.We were joined by Curve Finance Founder, Michael Egorov, to chat about why he created the protocol and his long term vision for the project.Topics covered in this episode:Michael's background and how he got into cryptoHow Curve works from the perspective of a trader and as a liquidity providerHow they came up with the stableswap designHow Curve compares to Uniswap v3Michael's take on forks, fork threat, and Curve's moatCurve's thesis on good governanceHow they keep the protocol secureAn overview of the Curve community and ecosystemThe long term vision for CurveEpisode links:Curve FinanceCurve ResourcesCurve on TwitterMichael on TwitterSponsors:ParaSwap: ParaSwap’s state-of-the-art algorithm beats the market price across all major DEXs and brings you the most optimized swaps with the best prices, and lowest slippage - http://paraswap.io/epicenter Solana: Solana is the high performance blockchain supporting over 50k transactions per second to power the next generation of decentralized applications. - https://solana.com/epicenterExodus: Exodus the easy-to-use crypto wallet available on all platforms and supporting over 100 different assets. - https://exodus.com/epicenterThis episode is hosted by Brian Fabian Crain & Zubin Koticha.
