Collin Myers & Oisín Kyne: Obol Network – Distributed Validator Technology (DVT) #497

Ethereum’s merge and transition to a proof-of-stake consensus implied switching from proof-of-work mining to transactions being validated by entities that have an economic stake in the network. Proof-of-stake distributed networks are subject to complex game theory models (e.g. slashing). Distributed validator technology (DVT) enables a more modular validator stack at every level: key pairs, hardware and entities. This reduces trust dependencies and increases security for validator entities.

We were joined by Collin Myers & Oisín Kyne, founders of Obol Network, to discuss Ethereum’s 2.0 PoS consensus, the current validator landscape and how distributed validator technology (DVT) allows for an increased security and overall smoother UX for validator entities.

#Umbra’s Stealth Payment System #shorts

Recording every transaction on a public ledger presents numerous advantages.
However…is privacy a price worth paying?

Ben DiFrancesco: Umbra – Privacy Preserving Token Transfers #496

Public transaction history in blockchains represents one of their key features which, alongside immutability, aim to provide an alternative to CeFi. However, this transparency comes at a price: privacy. As a result, different solutions have been proposed, that preserve privacy while maintaining all the other benefits of blockchain technology, but there currently isn’t a one-size-fits-all answer to this problem. For example, zero knowledge proofs convey the validity of a transaction batch without sharing any other details, but the underlying arithmetic circuits are both complex as well as computational intensive. Umbra proposes a system that relies completely on elliptic curve cryptography, employing multiple private-public key pairs to achieve stealth payments.

We were joined by Ben DiFrancesco, founder & CEO of ScopeLift, to talk about Umbra’s privacy preserving stealth token transfer system and if the need for privacy on blockchains outweighs any implicit UX frictions.

Emin Gün Sirer: Avalanche – The Future of Crypto: From Gaming to LLM-Powered Smart Contracts #495

As the second Avalanche summit drew to a close, Sebastien Couture and Sunny Aggarwal sat down with Emin Gün Sirer for a fascinating conversation exploring future innovation narratives in crypto. Longtime friend of Epicenter, Ava Labs’ founder and CEO shared his unique insights on the industry, from both a founder, as well as a former academia perspective.
Given Avalanche’s consensus & architecture, it boasts high TPS and scalability properties, incentivising founders to build better products in the AVAX ecosystem.

One of the most controversial narratives is that of LLMs (i.e. ChatGPT) powering smart contract development by bypassing programming languages and even bytecode altogether. The question arises if replacing the human third-party with an AI fixes trust issues or not, but only time will tell which piece of code we can actually consider ‘law’.

Jose Macedo: Mars Protocol – Red Bank’ Credit on Cosmos via Osmosis #493

The end of 2022 and beginning of 2023 were marked by centralised institutions failing: from CEXes to CeFi itself, contagion spread quickly in over-leveraged and opaque entities. Amidst this chaos, (crypto)people turned their hopes, once again, to DeFi. However, in lack of traditional enforcing mechanisms, not even battle-tested decentralised lending protocols could find a solution to provide under-collateralised loans, aka credit. Mars Protocol, with its unique hub & outposts architecture, aims to answer this need in the Cosmos ecosystem, by deploying on Osmosis and tapping into its deep liquidity. From manual leverage to credit and yield farming, Mars will feature a wide suite of DeFi products.

We were joined by Jose Macedo, founder of Delphi Labs, to discuss the history of Delphi Digital, their learnings from incubating projects and the vision behind Mars’ ‘Red Bank’ DeFi products.

John Letey: KYVE – Decentralised and Accessible Data Storage #492

We often take data storage for granted, but the rise of centralised storing facilities (i.e. AWS, GCP, Azure, etc.) hangs over like Damocles’ sword. When it comes to blockchains, full nodes store that network’s complete data history. Even if storage costs are set to decrease as technology evolves, so do blockchains accumulate more data over time. An interesting solution would be to create a decentralised backup for blockchain data and Arweave is a prime candidate for it. There is but a missing link represented by uploading and validating different blockchains’ data. This is where KYVE steps in, offering a decentralised validating solution to verify uploaded blockchain data and even retrieve it from Arweave, on demand. This also extends to off-chain data, opening new possibilities for data availability and scalability.

We were joined by John Letey, founder and CTO of KYVE Network, to discuss the challenges and use cases of decentralised data storage and how blockchain interoperability could benefit from it.

Tim Galebach: Uqbar – Smart Contracts on Urbit #491

Building a truly decentralised, peer-to-peer network, based on a built-in identity system, limits the ecosystem’s interoperability with the outside world. Onboarding developers and users to Urbit was only the first hurdle. On-ramping crypto was a whole different & daunting task. Uqbar set out to build an execution layer on top of Urbit, enabling smart contracts, which would ultimately settle, via a ZK rollup, on Starknet.

Laurence Ion & Vincent Weisser: Vita DAO – From DeSci to Longevity Research #488

Scientific research & publishing are gruelling tasks that extend outside the scope of science itself. Centralised publications abound in archaic practices that span from submitting a paper to getting it peer-reviewed and finally published, process which may take even up to years. In addition, research requires funding from very early stages of pursuing an idea, all the way to its finality (i.e. clinical trial or real-life applications). In TradSci (traditional science), funding is usually obtained once progress has already been achieved or when a startup has been formed.

DeSci (decentralised science) sets out to change this paradigm by funding early stage research via DAOs. When it comes to scientific publications, peer reviewing is also decentralised and incentivised, considerably speeding up the process. Moreover, contributions can be clearly retraced, avoiding false claims over IP, and the research itself becomes much more easily accessible and disseminated.

We were joined by Vincent Weisser & Laurence Ion, stewards of Vita DAO, to discuss the advantages of DeSci in general, and the progress of longevity research in particular.

David Schwartz & Jordi Baylina: Polygon zkEVM – From Mainnet to Mass Adoption – Part 2 #487

While Part 1 (#486) focused on the technological advancements that allowed proofs to be generated in a practical manner, lowering both the time and the hardware requirements, in this episode, we take a closer look at the use cases of different types of zk rollups and how they could promote blockchain mass adoption. Polygon’s zk EVM equivalence, coupled with low transaction fees, promise a frictionless user experience. As with all L2 rollups, sequencer decentralisation remains a pressing issue that needs to be solved.

We were joined by Jordi Baylina (tech lead) & David Schwartz (CTO) from Polygon’s zkEVM, to discuss the relationship between Polygon’s multiple zk rollups, their use cases, as well as network statistics for zk-EVM.
