A Modest Proposal for Ethereum 2.0
Vitalik Buterin gives his talk titled, "A Modest Proposal for Ethereum 2.0"
"It's 10pm, do you know where your mnemonic is?"
Many stakers set up their validators nearly two years ago, and will soon need to revisit them to obtain the rewards they have earned since. This panel provides a refresher for what stakers did, and why they did it. It discusses protecting mnemonics and keys, and what can be done if they are misplaced or compromised. Bringing together experts on validating key creation, protection and use, this is a wide-ranging discussion that will be useful for all stakers and potential stakers.
The CBC Casper Roadmap
The CBC Casper roadmap is a plan to implement Proof-of-Stake and Sharding for Ethereum using “correct-by-construction” (CBC) software design methodology. This talk will share new CBC Casper research, including specifications for light clients, liveness and sharding. It will include updates on formal verification and engineering efforts, and a roadmap for (eventual) release.
Why Dapp Users will Hate Cross-Shard Communication (and what you can do about it)
ETH2 is approaching, and initial indications are that substantially all dapp experiences will suffer. Some problems may be addressed with significant changes to design and development processes, but several tradeoffs are unavoidable without sacrificing scale, security, or decentralization. For example, essentially all popular dapps rely on the fungibility of Ether in a managed pool (e.g. Uniswap, Augur, Maker). In a sharded ecosystem, Ether is meaningfully non-fungible across shards, and users will bear monetary and management costs as a result.This talk will give an overview of cross-shard communication strategies and discuss their impact on developer and user experience. These include merged consensus, shard relays, consensus introspection, and credit markets. For each mechanism, we'll discuss expected impact on user experience metrics like execution time, transaction outcome, and price slippage.The talk is not all bad news. We've discovered some elegant new approaches that give dapps a variety of communication choices. The last section of the talk will discuss specific communication strategies that are amenable to specifi
Beyond Stake: Implementing Diversity Policies on PoS
We look at the challenges of implementing various diversity-improving policies on a PoS network. Economic (dis)incentivization is a popular approach, but can be undermined by non-standard miner economics such as (cross-domain) MEV or derivatives on incentivization. As an alternative, we outline an approach to include diversity support into the consensus level without requiring changing the basic functionality of the protocol by adapting the concept of general adversary structures.
Cryptoeconomics Dive: LP Volatility Harvesting Across Yield Rates
This talk furthers the concept of volatility harvesting. Currently, Uniswap and other major dexes see a huge part of their trading volume consist of the result of volatility in the market. Value changes and as a result, trading volume spikes and LPs profit. When extending yield, which is also quite a volatile concept, to AMMs, volatility harvesting is increased further to not only affect value but also the yield that value creates.
Nano-payments on Ethereum

Interblockchain Communication & Interchain Topology
The interblockchain community protocol will faciliate permissionless interoperation between smart contracts on Ethereum 1.0/1.x & Ethereum 2.0, Cosmos zones, Polkadot parachains, Bitcoin & more. The first half of this talk presents the protocol construction, notes security properties & consensus requirements, explains the message channel interface exposed to smart contracts & modules, and discusses special techniques for bridging Nakamoto proof-of-work consensus blockchains such as Ethereum 1.0/1.x to chains with finality. The second half embarks on a speculative exploration of what the future topology of interconnected blockchains might look like: what economic constraints might shape cross-chain design choices, what kinds of applications might most benefit from cross-chain logic, and what shared ecosystem standards might most effectively facilitate positive-sum interoperation, with particular attention to integration into the Ethereum 2.0 specification process.
Polkadot's Data Availability and Validity Scheme
How can we make blockchains secure at scale? We suggest a data availabilitty and validity scheme that make sharding efficient in terms of the number of validators and validating resources. We first describe the Polkadot data availability and validity scheme and consider its applicability to other sharded systems (e.g. ETH2.0). In Polkadot we tie an erasure coding data availability scheme with consensus, where we can not finalise an unavailable block. Moreover, reports of unavailability or invalidity trigger extra checks. The aim is that, with high probability, we do not finalise an unavailable or invalid block provided that there are enough honest actors to report. The key advantage of this scheme is that we need fewer validating actors per shard and in turn less total computational and especially networking resources. This softens the trade-off between scalability and security.
A Breakdown of Ethereum Supply Distribution Since Genesis
As Ethereum looks ahead to its transition to a fully to a proof-of-stake consensus protocol, the topic of Ethereum’s supply distribution matters more than ever to network stakeholders. This is because under PoS, the amount of ETH users control directly determines how much influence they can have over the network’s consensus building process and the amount of rewards they can earn from staking. This talk dives into how distributed ETH supply on Ethereum has become over the last 7 years.
