As we take some time to record new interviews, we’re releasing content from DappCon which took place in Berlin in August. This week, you’ll hear a panel moderated by Sunny all about blockchain governance. The panelists where Ameen Soleimani of MolochDAO, Stephanie Hurder of Prysm Group, Jorge Izquierdo of Aragon One, and Sebastian Gajek of ditCraf. Topics covered in this episode: Hard Governance vs. Soft GovernanceWhat types of governance we should apply to different systemsDifferent approaches to governance formalizationHow we should govern things like trademarksRepresenting all stakeholders in a governance systemBuilding in exit mechanisms in DAOsConservatism over Liberlism in governance mechanismsHow to account for different value systemsEpisode links: DappConAmeen Soleimani on TwitterStephanie Hurder on TwitterJorge Izquierdo on TwitterSebastian Gajek on TwitterCommunity manager job postingEpicenter Meetup at SF Blockchain WeekThis episode is hosted by Sunny Aggarwal.

Those who have been in crypto long enough remember the not-so-good-ol’ days when an air-gapped machine was the only way to store private keys securely. Thankfully, the wallet space has come a long way from that era. But we still live in a world where the seed phrase is the single atomic point of failure. Enter threshold signatures schemes (TSS), a multi-party computation (MPC) where different parties generate a key and are all required to create a valid signature.  We’re joined by Omer Shlomovits and Ouriel Ohayon, Co-founders of ZenGo. Their product is a ‘keyless’ crypto wallet, which means users never need to generate or store a key which gives them access to their funds. Keys are created with an MPC, where both ZenGo and the user are required to sign a transaction. TTS opens up exciting new possibilities like social recovery, user permissions for teams, and inheritance planning schemes. The important distinction between ZenGo and existing multi-signature wallets is that they achieve this using only cryptography, and do not rely on on-chain elements like smart contracts or op_scriptSig in Bitcoin. Topics covered in this episode: - Omer and Ouriel’s respective backgrounds in academia and online consumer-facing products - What lead them to want to build yet another crypto wallet - The state of custody in the crypto wallet ecosystem and the challenge which remain unaddressed - A quick refresh on cryptographic primitives and multi-party computations (MPC) - The building blocks of cryptographic signatures and threshold signature schemes (TSS) - How TSS is different from Bitcoin multi-sig and smart contract multi-sig - TSS in ECDSA vs. Schnorr signatures - Applications and use cases for TSS - ZenGo’s on-boarding, restore process and use of biometrics - The future of wallet interoperability in a world of proprietary cryptographic schemes Episode links:  - [ZenGo: Bitcoin & Cryptocurrency Wallet](https://zengo.com) - [‎ZenGo: Bitcoin & Crypto Wallet on the App Store](https://Zengo.com/enjoy) - [Threshold Signatures Explained](https://www.binance.vision/security/threshold-signatures-explained) - [ShareLock: Mixing for Cryptocurrencies from Multiparty ECDSA](https://eprint.iacr.org/2019/563.pdf) - [KZen Networks on GitHub](https://github.com/KZen-networks) - [Zengo Research](https://zengo.com/research/) - [KZen Research Telegram Group](https://t.me/kzen_research) - [Tel Aviv Blockchain Week Recap with Anna Rose of the Zero Knowledge Podcast](https://www.youtube.com/watch?v=ccywXWTSFKM) Sponsors:  - Vaultoro: Trade gold to Bitcoin instantly and securely starting at just 1mg - http://vaultoro.com - Trail of Bits: Trust the team at the forefront of blockchain security research - https://trailofbits.com This episode is hosted by Sebastien Couture & Brian Fabian Crain.
