What can you expect from the Merge? What are the challenges and opportunities presented to smaller client developers? What impact will new technologies like Bonsai and Snapsync have for client operators? Learn about all this and more in this Merge special episode of PEEPanEIP.

What is the future of voting on chain? What are the challenges in creating an Ethereum Standard for voting methods? Victor Zhou joins us to discuss the challenges of voting and the changes EIP-1202 could bring.

How do upgrades to the EVM get introduced? What are the challenges to upgrading the foundation of a system as large as Ethereum? Andrei Maiboroda joins us to discuss the challenges of incremental upgrades to the EVM and the changes EIP 3540 and EIP 3670 will bring.

Why don't we all host our own nodes? What role do individual node operators play in the decentralization of blockchains? Why should we care about Self Sovereignty? Pol Lanski, Project Lead at DApp Node joins us to discuss the challenges of node incentives and the changes Ethereum's Consensus layer will bring. We also discuss how DApp Node provides consumer-focused products while remaining deeply committed to decentralization.

Do blockchains help with privacy or hinder it? Why do we need transactional privacy? Roman Semenov, creator and builder at Tornado Cash joins us to discuss privacy on blockchains and how Tornado strives to improve it. We also discuss the differences between the original version of Tornado and Nova, the new version of Tornado which is rolling out now.

One of the pillars of the ideology around web3 is that of decentralization. Are we delivering on our promises to create decentralized ledgers, or are we falling into the same snares that gave us the highly centralized internet we see around us? Kristy Leigh Minehan, noted consultant and blockchain hardware specialist joins the podcast to talk about decentralization from a number of different potential centralization vectors.

What could be hard about building a crypto wallet? Taylor Monahan, founder of MyCryto (recently acquired by ConsenSys) and currently at MetaMask, joins the podcast to discuss the intricacies of wallets, the challenges in presenting something decentralized and yet user-friendly to a spectrum of users, and more.

We've all heard of DAOs, but what are they practically? How can you contribute to one if you wanted to? What different challenges do DAOs and those contributing to them face? Chase Chapman, a DAO researcher and contributor joins the podcast to talk about all things DAOs.

Running nodes on the Ethereum network (and other blockchain networks) can be hard. The client software can update frequently and be hard to work with. In addition, they need monitoring and maintenance. The data provided as specified can be difficult to work with too. Yet, nodes are necessary to connect applications with the blockchain. The difficulties and need have led to the rise of providers running nodes as a service and providing an API for app builders to use to connect their application to the blockchain. Alchemy is one such provider. Deric Chang and Omar Ceja of Alchemy join to discuss running node infrastructure at scale, and providing useful data to users.

Building apps that aggregate blockchain data opens up new paradigms in application development. Lefteris Karapetsas, a longtime contributor to the Ethereum ecosystem, joins the podcast to discuss his current project, Rotki, a crypto asset accounting app. We discuss the difficulties of obtaining event data from nodes, the benefits and challenges of developing in the open, and more.

Smart Contracts can hold immense amounts of value in an ecosystem that makes them accessible to anyone. As a result, exploits in smart contracts can have catastrophic results. samczsun, a researcher at Paradigm and famous white-hat hacker, joins us to talk about finding vulnerabilities in smart contracts. Among the topics, we talk about his preferred setup for analyzing contracts, how he picks what to look at, and how he goes about looking at code once he's picked something. We also talk about anonymity in the space and his work at Paradigm and previous.

Nethermind is an execution client for EVM-compatible blockchains. Tomasz Stańczak discusses what motivated him to begin working on creating a new execution client and the specific challenges (and joys) of building and maintaining one. We also discuss some of Nethermind's specific features as a client, and future directions for both the larger Nethermind company and the client specifically.

Smart contracts have opened up new opportunities, and we are still exploring what we are able to build with them. Andre Cronje is the creator of Yearn Finance, Keep3r, and more, and joins us in this episode to talk about building innovative platforms with smart contracts, and the various pressures that can come from being a recognized builder in the space.
