With Proof-of-Stake (PoS) a blockchain is secured not by spending an external resource such as electricity but by using value internal to the chain itself. The promise of higher security at a lower cost is what also drives Ethereum to plan a move away from Proof-of-Work to PoS in the future.

Ethereum researcher Vlad Zamfir, who leads their effort in the complex search for the optimal PoS consensus system joined us for an in-depth discussion of the challenges of PoS, the approach Casper is taking and what consensus in Ethereum land could look like in the future.

Topics covered in this episode:

How he became interested in consensus and Proof-of-Stake (PoS)
Why Ethereum plans to switch to the PoS systems Casper in the future
What the Long-Range Attack and Nothing-at-Stake problems are and how Casper addresses them
How a betting mechanism is used to get validators to reach consensus
What centralization pressures exist for validators and what operating a validator will look like
The role of security deposits in Casper
The difference between Tendermint and Casper
Whether forks create big UI/UX issues for Casper
Why Casper is very light client friendly

1:01:40

‘Attention Is All You Need’, co-wrote by Illia Polosukhin in 2017, laid the foundation for arguably one of the most consequential tech breakthroughs in our recent history. 1 year later, Illia founded Near AI, which later became Near Protocol. They were visionaries ahead of their time and, although AI took several more years before becoming a viable product, the experience of scaling databases would later prove valuable and applicable in blockchain world. As a result, Near Protocol aims to become the infrastructure layer for AI apps and the agentic economy. In order to achieve this, scaling was paramount, thus Near is one of the first blockchains to implement execution layer sharding, asynchronous execution and stateless validation, which brought the finality time down to 1.2 seconds, with a block time of 0.6 seconds. Topics covered in this episode: Bowen’s background Near’s pivot from AI to blockchains The role of Near One Near’s tech stack upgrades Optimizing network architecture Stateless validation & block propagation Sharding & asynchronous execution Message passing between shards & shard ‘equality’ Challenges of implementing stateless validation Applications benefiting from Near’s finality speed Intent-based infrastructure AI use cases on Near Expanding Near’s ecosystem Development challenges Near’s vision and goals Episode links: Bowen Wang on X Near One Near on X Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

Bitcoin remains an untapped source of net-new liquidity that could be injected into DeFi. This would completely reshape Bitcoin’s utilization from a mere store of value to a liquid asset that can be ported cross-chain and traded like a liquid staking derivative. Lombard’s LBTC builds upon Babylon’s Bitcoin staking primitive and aims to unlock new yield sources for the industry’s leading asset by increasing its DeFi utilization. Topics covered in this episode: Jacob’s background Lessons gathered from Polychain Focusing on Bitcoin Why Bitcoin staking is crucial for BTC DeFi Building on top of Babylon LBTC minting Sources of BTC yield PoS inflation and native token incentives BTC as a trading pair in DeFi Lombard chain Future challenges to overcome Bitcoin L2s Lombard milestones Episode links: Jacob Phillips on X Lombard on X Babylon on X Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

Staking Rewards: Is Crypto Staking Killing Decentralisation? - Mirko Schmiedl & Tobias Jung 54:55

۸ weeks پیش54:55

54:55

Apart from incentivising market participants to secure the network through inflationary rewards, many consider staking as an equivalent of stock dividend yield. As a result, although Bitcoin is regarded as digital gold, protocols are looking for ways to increase its utilisation in DeFi and, ultimately, generate yield. Nowadays, while newer networks are struggling to attract investors and sustain a healthy, decentralised validator set, more established blockchains capture the lion’s share of PoS actors. However, in a constant race for profit basis points, centralised consolidation of stakers seems inevitable. Join us for a fascinating discussion on the staking landscape and the challenges it may present to decentralisation.

After a decade of existence, Ethereum has gone a long way from its initial whitepaper, yet many efforts in scaling and finding product-market-fit have been severely criticized for falling short of their promise. However, despite numerous other ‘Ethereum killers’ being launched over the years, none has managed to attract so many developers and liquidity while sticking true to ethos that (once) powered and united this industry. This year’s ETHPrague plans to confront exactly these existential challenges and steward community culture towards addressing outside criticism and external reality checks. Ethereum’s development, while adapting to market pressures, it always aimed to stick true to its core values in order to remain a technological bedrock for the future of humanity. Topics covered in this episode: The vision for ETH Prague Takeaways from main sessions High-level overview of ETH Prague The resurgence of Polkadot European crypto summer events The general state of the Ethereum ecosystem Celo’s transition to L2 L2 liquidity fragmentation Choosing the right L2 to build Improving hackathons Lightning round Final words Episode links: Austin Griffith on X Marek Olszewski on X Brenda Loya on X Joseph Schweitzer on X BuidlGuidl DAO on X Celo on X Tellor on X Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

Initia: Incentively Aligned Appchains - Ezaan Mangalji, Anil Lulla & Jose Maria Macedo 1:02:08

10 weeks پیش1:02:08

1:02:08

Blockchain architecture is constantly being forced to adapt to new technologies, as well as to meet new demands from users and builders. While the idea of apps building their own chains was first explored by Cosmos, it lacked the support and tooling to see it succeed. Later on, rollups also took the centerstage of Ethereum’s scaling roadmap, but due to their general purpose design, it led to a cannibalistic ecosystem. Initia learned from these 2 models and combined the best of both worlds: it built a full-stack framework for a seamless DevEx from the get-go and, more importantly, it designed its tokenomics in order to ensure maximum incentive alignment for its appchains. While the former decision removed the need for each separate chain to reinvent the wheel and risk ending up ‘a jack of all trades, master of none’, the latter ensured that appchains would not extract value away from the L1. Topics covered in this episode: Ezaan’s background From building on Terra to Initia How Initia is rewriting the appchain thesis Initia’s enshrined liquidity & vested interest program (VIP) Metrics & Initia’s bet on crypto innovation Solving liquidity fragmentation Delphi’s involvement in Initia Future roadmap Episode links: Ezaan Mangalji on X Jose Maria Macedo on X Anil Lulla on X Initia on X Delphi Digital on X Delphi report on Initia Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

As society evolves, so do its values and principles, but is that desirable for technology that seeks to build the most reliable, trustless and censorship resistant global settlement layer? Ever since the rise in popularity of Solana with its inflow of retail capital in a memecoin gold rush, Ethereum became even more criticized for sticking true to its core values despite the completely divergent demands of market participants. Moreover, the rollup centric scaling roadmap seemed to further silo attention and cause liquidity fragmentation, driving away value from Ethereum mainnet. As institutional demand is expected to grow with the introduction of staking ETFs, a new executive leadership took charge of Ethereum foundation to help steer the protocol’s narrative at the intersection between community demands and Ethereum’s ethos. Topics covered in this episode: Hsiao-Wei’s & Tomasz’ backgrounds How they became co-executive directors of Ethereum Foundation Ethereum Foundation’s role moving forward Decision making in Ethereum Foundation Shaping Ethereum’s narrative The layer 2 landscape Scaling Ethereum as the global settlement layer Sharding Rollup scalability & their trade-offs What values drive adoption L2 interoperability Future goals Episode links: Hsiao-Wei Wang on X Tomasz Stanczak on X Ethereum Foundation on X Ethereum on X Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

Taiko is a decentralized, Ethereum-equivalent (type I) rollup scaling solution which uses ZK technology. Taiko's goal is to scale Ethereum efficiently while maintaining security and decentralization. Being a type I zkEVM, Taiko retains full Ethereum equivalence, which creates a seamless DevEx, although this comes at the expense of UX as slower proof generation is the main trade-off. Moreover, in order to stay true to its decentralised ethos, Taiko operates as a based rollup, meaning that transaction sequencing is performed by L1 validators. Topics covered in this episode: Joaquin’s background Loopring and Taiko’s beginnings The 4 types of zkEVMs Taiko's zk circuits vs. Polygon’s Based sequencing Data availability and blob commitment Ethereum’s role in the future The L2 landscape and its compromises Sequencer security model Dealing with MEV Based preconfirmations & Taiko ecosystem UX Episode links: Joaquin Mendes on X Taiko on X Loopring on X Sponsors: Gnosis: Gnosis builds decentralized infrastructure for the Ethereum ecosystem, since 2015.

Traditional KYC and AML regulations have often forced companies to comply, without having the right tools to do so. Simply storing users’ personal information led to the creation of security honeypots which haven’t gone unnoticed by hackers. Web3 solutions like Privado ID aim to cryptographically prove certain traits from a user’s personal data, without disclosing it to the enquirer. This is usually made possible through zero knowledge proofs which allow users to store their personal data on their own device and only exchange verifiable credentials with trusted issuers. City of Buenos Aires has adopted a similar implementation through their Quark ID system, a digital trust framework that creates a new digital identity system, giving people control over their information.
