Zooko, invited guest to chat about his background and explore the history of Zerocoin and Zcash. They discuss the Sapling upgrade, reducing proving times, trusted setup, and the future prospects of Zcash. They also touch on encryption, zero-knowledge proofs, the toxic waste problem, compressing witnesses, and improving smart contract execution through Z-X-E.

In this Blockchain 101 episode, we sit down with Axel Ericsson of Vest (previously 1Protocol) to talk about Cryptoeconomic Primitives, incentive models, designing smart equilibria, and staking. Links: Game Theory Game Vest on Twitter Axel on Twitter Vest Website

In this episode, we sit down with Taylor Monahan of MyCrypto, to discuss how the project got started and share some customer support horror stories. We also reflect on the challenge of building UX that works for people while maintaining the spirit of decentralization, and finally, where she sees the space developing.

In this episode, we sit down with Richard Craib from Numerai to talk about crowdsourcing the role of a quant, how Numerai developed and where it is going, Dapp adoption in Ethereum and what it's like to build a hedge fund fulled by a crypto token. He also shares the new project Erasure - a decentralized data marketplace for financial predictions. Follow Richard on Twitter Learn more about Numerai

We finally sit down with Gavin to go through a bit of what Parity has been working on with Polkadot and Substrate. We talk about Polkadot early history and who was involved and where the idea spawned, up to coding practices and where Substrate became a thing. If you want to know more, links below.

In this week's episode, we sit down with Henri Pihkala from Streamr to talk p2p messaging and what it means. We cover topics like pubsub, compare it to whisper, talk about the needs of different messaging systems as well as dig into why one would want to decentralize something like this. Finally we take a look at the data marketplace idea that streamr is trying out and what potential use-cases that could have.

In this episode, we are joined by Tomasz Drwięga, a Core Developer at Parity Technologies, to discuss the lifecycle of a transaction on the Ethereum network and how the mempool works. We will be covering the following topics: What a mempool/transaction queue/transaction pool is. How a transaction reaches a mempool and what the mempool does with it. Looking at what causes the CPU increase and delays in the network. What happens when a transaction gets stuck. Gossip. The security properties of the mempool. What a network attack could look like.

In this episode, we chat with Hudson Jameson of the Ethereum Foundation about how he got involved in the space, the EIP process, and the challenges of decision making in the decentralised space. In decentralised communities, decision making and information gathering can be a uniquely difficult endeavor. Using some of the ideas from other open source communities as well as some new concepts emerging specifically for decentralised spaces, the Ethereum core devs are developing new tools to make these decisions more effectively.

In this episode, we sit down with Mitch Kosowski, director of product at ETHPrize and Andrew Cravenho, project leader at POA Network. We cover ETHPrize's inception and activity, the way that pain points in the community are identified, and the open source block explorer project that POA Network is building with an ETHPrize bounty. ETHPrize developed out of a series of interviews with devs in the community. Unlike traditional grants, ETHPrize aims to use bounties, sub-communities and working groups to tackle specific problems emerging in the ecosystem. ETHPrize is funded by 0x, Status, ECF, CoinbaseWallet and Ethereum Foundation and initialised by Robbie Bent and inspired by the findings in the ETHReport Read more about the open source block explorer - https://medium.com/poa-network/introducing-blockscout-the-ethereum-explorer-86b4ddd9e8a4 Here are some additional links: ETHPrize website Mitch's Twitter contact Andrew's Twitter contact POA Network website

Jacob Eberhardt, a contributor to the Zokrates project and the Zero Knowledge Proof Toolkit, discusses off-chaining in blockchains, the implementation of Zokrates, benefits of Wasm blockchains and Rust, and different approaches to off-chain computation. They also touch on the adoption of theory into practice and the naming of academic concepts.
