Devcon2: Regulatory Considerations for Dapp Development.

Dapp development and token distribution particularly, pose unique questions for regulators and law enforcement. Ethereum Foundation Executive Director, Ming Chan, will introduce the topic of regulatory issues when creating Dapps, followed by Peter Van Valkenburgh introducing Coin Center. Peter will give a brief summary of Coin Center's advocacy work and the current legal landscape surrounding these technologies.

Speakers: Ming Chan and Peter Van Valkenburgh

Devcon2: The Mauve Revolution
Speaker: Vitalik Buterin

Proof of stake and sharding present two of the biggest upcoming milestones in the ongoing development of the Ethereum protocol. Proof of stake offers the promise to greatly reduce the cost of consensus and increase security guarantees, while sharding presents an approach to allow on-chain scaling to tens of thousands of transactions per second while still retaining a network that can, if needed, run on nothing but a sufficiently large set of consumer laptops. The Casper approach to proof of stake also introduces a number of novel concepts, including consensus-by-bet and fork choice by value-at-loss.

Devcon2: A Correct by Construction Asynchronous Casper Protocol
Speaker: Vlad Zamfir

This technical talk covers the ongoing formal verification and implementation efforts behind a correct-by-construction asynchronous byzantine-fault tolerant binary version of the Casper consensus protocol that is currently under development. Work extending the correct-by-construction approach to virtual machine replication, validator rotation and public economic consensus will also be discussed.

Devcon2: Zcash + Ethereum = ❤
Speaker: Zooko Wilcox

This presentation focuses on how Zcash uses zero-knowledge proofs to add private transactions to a public blockchain, and how Zcash and Ethereum will grow together.

Zcash is a new cryptocurrency that provides private transactions — the sender’s and receiver’s addresses are not publicly visible in the blockchain, nor is the amount transferred.

Zcash posts that private information to the blockchain in encrypted form, and uses zero-knowledge proofs to cryptographically guarantee the validity of transactions without exposing the private information.

This results in “Selective Transparency”. It’s not all-dark-all-the-time — it’s that each encrypted transaction in the blockchain can be revealed by its creator to selected third parties.

Zcash is developed by a VC-funded, highly skilled development team and a widespread and active open source community. There are three paths forward for integrating Ethereum’s programmability with Zcash’s privacy. The Zcash team is actively contributing to all three paths.

1. Programmable Zcash — add Ethereum-style programmability to the
Zcash blockchain

2. Private Ethereum — add Zcash-style privacy to the Ethereum
blockchain

3. Project Alchemy — interoperation between the Ethereum and Zcash
