Chorus One Podcast

On the show today we have Sunny Aggarwal and Josh Lee, co-founders of Osmosis. Osmosis is a fair-launched, customizable automated market maker for interchain assets. Osmosis' differentiator compared to other decentralised exchanges is the customisation it gives all participants in the network. For example, liquidity pool creators have the flexibility to create their own formulas and fees that determine prices of assets. Liquidity providers have customisable tools to provide liquidity to suit their own risk preferences. Whilst users can swap any asset connected to the IBC, making it the world's first truly interoperable AMM. During the show, we discuss Osmosis network launch, the first stress-test of IBC, the importance of privacy on DEXs, reverse staking derivatives and more.

On the show today we have Scott Sigel, Director of Operations for the Decentralized Wireless Alliance. Helium network is a novel decentralised network because it is not just a blockchain or an application, but a worldwide decentralised physical wireless network, powered by hotspots. The wireless network is known as LongFi and incorporates state-of-the-art wireless network tech with blockchain. Companies use Helium network as a cost-effective alternative to track their IoT devices and network participants set-up hotspots to earn HNT rewards. We have Scott on the show today to talk about their newly announced transition to a Proof-of-Stake network and cover things ranging from hotspots to consensus to their ambitions to build the world's first user-owned 5G network.

On the show today we have Tushar Aggarwal, CEO of Persistence One. Persistence One is a network in the Cosmos ecosystem with bold ambitions to bridge traditional finance to decentralised finance. Already with 5 products outstanding, we took the time to speak with Tushar about Persistence's journey so far. In the show we discuss the many products of Persistence, their initial use of validating nodes to bootstrap their protocol, their future plans to bring liquid staking to Cosmos, the importance of interoperability for liquidity and a lot more.

Lunie is a multi-network wallet focused on staking networks and on-chain governance. Lunie was one of the first wallets for Cosmos (then Voyager) and has since expanded to support multiple networks from the Cosmos ecosystem (Terra, E-Money) with Polkadot and other networks coming soon.

In this episode, Felix is joined by Jordan Bibla. CEO and Co-Founder of Lunie, to discuss the crypto wallet and staking ecosystems. The episode begins going into the background of Lunie and the products the team has built (web and mobile apps, as well as a browser extension). Felix and Jordan explore UX difficulties in staking networks, how newly launching networks should go about building communities, protocol governance, and insights from developing one of the most used wallets focused on staking. The second part of the episode dives into Lunie's upcoming freemium notification feature and Jordan shares his views on the most important developments in the blockchain ecosystem.

In this episode, Brendan and Felix are joined by Soravis Srinawakoon, Co-Founder and CEO of Band Protocol, a data governance framework for Web3. Band is soon launching its own Cosmos SDK chain focused on provisioning oracle data for blockchain applications.

We cover what the oracle problem is, how Band is able to provide off-chain data to blockchain applications in a single transaction, what the team imagines the role of Band Chain to be within the ecosystem and take a look at the parties involved in Band's ecosystem. The second part of our conversation focuses on decentralized finance and the need for reliable oracle solutions, as well as a discussion of recent events following the "Black Thursday" crash that shook the Ethereum DeFi ecosystem. We wrap up with Soravis telling us about upcoming hackathons and the current state of the network leading up to mainnet.

Centrifuge is building the operating system for trade finance. In this episode, Brian is joined by Lukas Vogelsang, CEO of Centrifuge, to speak about the technologies Centrifuge is building to enable more efficient, transparent, and privacy-preserving supply chain financing.

We start by exploring the background of the idea and the founders' decade long background in the area of trade finance with Taulia, a company focused on invoice financing and working capital management, which is currently handling over $20bn in invoices a year. Lukas then goes into how his interest in crypto and the idea for Centrifuge, which is to build to tools to bring off-chain financial assets into the decentralized finance ecosystem, came about. He goes into how Centrifuge turns off-chain documents such as invoices into NFTs and how these NFTs can be bundled into collateralized pools to enable their usage in DeFi using Centrifuge's asset-backed lending protocol Tinlake. Lukas explains the advantages of transparency for asset-backed lending, Tinlake's tranched two token model, and their experiments using this system in collaboration with the Maker team and other partners such as Paperchain and Shuttle One. Lukas goes into how real-world assets as collateral could bring stability to Maker's Multi-Collateral DAI system.

Finally, Lukas talks about launching their own Substrate-based chain that allows Centrifuge to mint tokenized assets using Tinlake while maintaining privacy for asset originators.

In this episode, Felix is joined by Dieter "dete" Shirley, CTO at Dapper Labs. The team at Dapper Labs, a spin-off from Axiom Zen, are the creators of Cryptokitties and have spent recent years to create their own blockchain optimized for decentralized applications building on their learnings of writing some of the most widely used smart contracts.

The podcast begins with Dieter going into his background in crypto and how Cryptokitties emerged out of a series of ideas his former company at Axiom Zen had for blockchain applications. We then talk about how Cryptokitties helped the team realize both the benefits and shortcomings of Ethereum and Solidity development. Dieter explains how Flow is designed from the ground up with composability and developer experience in mind. We go into detail as to how Flow is able to scale by having multiple separate node roles, the interplay between them, as well as benefits that Flow tooling and the programming language Cadence provide to developers. Finally, we wrap up with a discussion of the economics in a blockchain with multiple different roles.

One of the major factors hampering blockchain adoption is that current decentralized applications only function when all associated data is public. Many real world use cases are only possible when participating parties can be assured that their information is kept private. Oasis is a network that is focused on enabling privacy-preserving smart contracts through the use of secure enclaves.

In this podcast episode, Meher and Brendan are joined by Andrew Miller and Vishwanath Raman, who are part of the Oasis Labs team working in product marketing (Andrew) and engineering (Vishwanath). The four start with a discussion of how Oasis got started and the connection to UC Berkeley. Then, in the first part of the interview, an overview of the Oasis protocol and key target markets follows. The episode discusses how the Oasis privacy protocol works technically and how it compares to other privacy-enhancing solutions. Specifically, Andrew and Vishwanath walk through a voting example and go through other use cases, features of the Oasis blockchain, the project's go-to-market strategy, as well as the roadmap including the ongoing incentivized testnet "The Quest". Finally, the four discuss implications of Intel security vulnerabilities and the developer experience of writing privacy-preserving smart contracts.

While most other upcoming smart contract platforms seem to have identified throughput as the major bottleneck for why blockchains haven't found mass adoption yet, Coda has focused on a different part of the stack that they perceive to be a much more important issue plaguing blockchain, which is how long it takes for new participants to verify the blockchain. Coda is using recursive zk-SNARK technology which enables them to create a constant-sized blockchain, making it really easy for clients to verify the correctness of the ledger. In this episode, Meher and Felix are joined by Emre Tekisalp, director of BD, and Brad Cohn, strategy & operations from the O(1) Labs team to discuss Coda's approach to building a new blockchain platform. The podcast starts out going into the background of the two, a high-level overview of Coda follows and we discuss what Coda's unique design enables and cover the go-to-market strategy of the project. From there the discussion leads us to discuss monetary policy and the implications of taxes on Proof-of-Stake networks. After this quick detour, we get back to discussing how the Coda protocol technically works leading to an extensive celebration of zk-SNARK technology during which Brad and Emre explain the progress in the field and why zk-SNARKs are so exciting. Finally, we wrap up the episode with some information on Coda's Genesis testnet program.

Insurance is a part of the finance stack that has received less attention in the Defi space compared to other segments like lending and derivatives. In this episode, Meher and Felix are joined by Marouane Hajji, Co-Founder at Unslashed, to talk about blockchain risk, insurance, and the protocol that Unslashed is building. We start out exploring why blockchain risks can't yet be insured using traditional insurance methods, as well as the go-to-market approach of Unslashed and their first product: a fully collateralized slashing insurance. We also discuss the interplay between staking derivatives and insurance and the interplay of the Melon Protocol and Unslashed to manage collateral for risk underwriters.
