Ethereum Curated

Learn More. He is also communicating the design patterns this technology is based on in a FOSS course called cryptoeconomics. Contributing to both the means and memes of decentralization. Ethereum's CTO Dr. The overview of the building blocks of an Ethereum client: what any client implementation should have. A practical perspective on how Ethereum works under the hood. So what are all of the different moving parts of the Ethereum blockchain?

What are uncles, how do contracts call other contracts, who runs them? What is the role of proof of work and proof of stake, and what exactly is gas? What will EIP86 do for you? Vitalik Buterin provides a minute technical overview of the ethereum blockchain, start to finish, and explain many of these concepts in detail. Greg Colvin, Dr. Christian Reitwiessner, Casey Detrio. This talk is about my experience building and using a block explorer for the Ethereum blockchain, which will provide a statistics highlight of the Ethereum blockchain and demographics of the Ethereum user base.

The demographics portion will based on analytical data generated over the past years from Etherscan. We demonstrate how complicated optimization problems can be solved by combining decentralized optimization algorithms with an aggregation step in a smart contract. Using tools from convex optimization, we decompose difficult problems into a set of subproblems with can be computed off-blockchain, finally reaching consensus on the global optimum by passing message with the on-blockchain aggregation step.

We present an example of applying this approach to optimizing power dispatch on an electricity grid, but the approach can also be used to solve other problems in machine learning, coordinating robotic agents, or coordinating economic systems. Why you can be certain that the four slashing conditions of Casper are enough to catch forks.

Thanks to an Ethereum Foundation grant, the team has taken the idea of an 'accountable watching service' further to help alleviate the online requirement for other off-chain protocols such as Plasma and in general most smart contracts. What do we mean that PISA is usable by most smart contracts?

Ideally, if we consider a smart contract where the user has to be online and watching for an on-chain event, then PISA can be hired to protect them and perform the final step. Our goal is to help improve the UX for most smart contracts as users can simply go off-line and PISA can finish the task in a financially accountable manner. In this talk, we'll discuss the substantial changes to PISA such that it can be generically used for most smart contracts. We'll discuss the implementation of PISA, the open-source project, and how other projects can use our simple API to sign up to the accountable watching service.

Mikhail Kalinin presents Complexities in Aggregation at Scale. Vitalik gives a quick overview behind Cryptoeconomics.

Ethereum 1. In this talk we go over the history of Eth 1. EVM Roundtable: everything you wanted to ask, but were afraid to. A fishbowl style conversation with passionate contributors to the EVM, but allowing anyone from the audience to stand up and lead a topic. The intent is to discuss certain key topics, such as how to evolve the EVM, what the most pressing issues are, and dissecting a handful of EVM proposals. Starting with a brief introduction, we explain the challenges, design directions, and the work done in the last 12 months.

We conclude with a roadmap of Ewasm. The session will consist of four parts: 1. Introduction 2. Is Wasm suitable for blockchain? This part will explain the changes if any needed for Wasm, questions relevant to blockchain, and solutions developed and proposed. This session aims to bring clarity to what execution on Eth 2.

It will be presented by multiple members of the Ewasm team, starting with a historical overview of how Eth 2. We will cover: - Scout an Eth 2. In this lightning talk, we will propose an auction mechanism to sponsor Ethereum Network Upgrades and use the proceeds to fund Ethereum 1. The talk will quickly! CBC Casper is a promising protocol for the future of Ethereum.

However, the research of CBC Casper is still in progress, even about its fundamentals. For example, Casper has been criticized for the lack of liveness proof for a long time. Therefore, we first introduce our liveness proof. The more detailed agenda is: 1 Liveness: We first introduce our liveness proof, which is applicable to each family of CBC Casper.

In particular, the notable feature of CBC Casper is "subjective finality", where validators can pick up their own fault threshold. We discuss how this feature affects cartel resistance. Blockchain platforms are maturing to enable decentralized architecture but vary in design depending on deployment environments, such as open digital ecosystems or contained multiparty environments. In this session we provide a summary of Gartner's observations on blockchain platforms adoption, a functional framework for assessing blockchain platforms, and future projections on blockchain platforms technical evolution.

Improving the federated 2-way peg: A new sidechain design for trustless bridges on Ethereum. In this talk, we'll introduce a novel mechanism to maintain 2-way pegs, as well an initial implementation of a Bitcoin peg on Ethereum. Problem Bitcoin's stable codebase is a strength. Developers are loathe to introduce significant changes, reasoning that a store of value should prioritize stable operation. While this cemented Bitcoin's place in the market, we all know the costs- Bitcoin's ossification at the expense of public experimentation and diverse use cases.

In , the answer to this problem was "sidechains". Trustless sidechains are the ultimate vaporware- and since the goalposts have moved. Approaches Blockstream's Liquid touted itself as the "first production sidechain", built on a multi-sig federation. No hashpower validates the sidechain-- funds are fully trusted to 15 Bitcoin multi-sig participants.

Unfortunately, they require KYC : These centralized projects have a few custodians that can be convinced by governments-- or their own interests-- to censor or seize funds. We believe this is the best candidate for a sufficiently trust-minimized alternative, unlocking Bitcoin for use in DeFi.

How do you connect to mainnet? To minimize effort, there is one obvious answer: Infura. Infura has its place, but using it everywhere means giving up so many of the core promises that Ethereum makes. So how can we make it easier to run your own node and actually deliver on Ethereum's promises? One of the worst parts of starting up your own node from scratch is the launch time.

If you're very lucky, you can count launch time in hours. Any less lucky, and you'll be counting in days. In this talk, I explore how to reduce cold-start launch time to minutes. I cover the approach of downloading just the state required to execute the most recent blocks. It requires a new execution strategy, and is significantly accelerated by a supplemental network protocol.

I show the progress in a client that I prototyped it in: Trinity. Significant progress has been made towards an efficient and truly decentralized network incentivization model. In addition to solving the hard problem of LES service availability, it can also serve as a PoC for our future networks where a proper incentivization layer will be key to a scalable and reliable infrastructure.

The talk covers the following topics: - the challenges of creating a healthy service market in a low-trust environment - building trust between pseudonymous participants without central authorities - guarantees for good performance and quick response times - a two-layered model that allows using different pricing schemes on top of a common simple base layer - more advanced applications and network topologies - a quick demo of how you can already use micropayments with LES.

Join us to consider options for collaboration between the Ethereum and Ethereum Classic communities. As a result of significant changes underway in ETC, there are several new and positive sum opportunities for cooperation. We will discuss specific paths for technical development and community engagement going forward.

We will also announce several new and exciting developments. A number of optimization techniques for Ethereum Virtual Machine implementations are going to be presented along with examples and benchmarks based on evmone and EVMJIT projects. All of the optimizations are applicable to any compiled language, some of them even to interpreted languages. This talk will explain the rationale behind the decision and then talk about overcoming or playing around the limit. The talk will cover ways like proxy patterns and libraries for working around the limit.

Tips on optimizing code for reducing bytecode size will also be shared. The talk will then explain new proposals for removing the contract size limit while still fixing the original problem. Running data-intensive applications on top of existing blockchain platforms remains a challenge. Modern blockchains are designed for maximum security and have limited compute and storage capacity, which means they are too expensive to handle nontrivial amounts of data.

However, traditional applications often need high transaction throughput and low latency of request processing. I will show how to address the scalability and cost efficiency requirements with a hybrid architecture composed of several layers.

Speed layer consists of real-time shards directly talking to a client; security layer provides finality and consists of fishermen verifying past speed layer behavior; dispute resolution is served by the Ethereum smart contract; finally, decentralized storage networks such as Swarm or IPFS provide data availability. In this talk, we will go through the hybrid architecture approach and explore how it can make the cost of running a classical database e.

Probabilistic Micropayments, in which a sender pays a recipient with a form of lottery ticket for services performed, present an alternative payment scaling solution to state channels that bring advantages in certain use cases such as stream data processing and distributed compute. In this talk we'll present an overview of this form of micropayments, compare and contrast them to hub and spoke payment channels, show the security model against double-spends, present benchmarks from real world usage within the Livepeer protocol, and showcase an open source implementation.

SimBlock is a blockchain network simulator. It was designed as an event-driven simulator wherein each participating node behaves according to generated events, e. This simulator supports Bitcoin, Dogecoin, Litecoin networks and has already been used in several studies about block propagation delay and fork rate. We are developing to support Ethereum, which will allow Ethereum developers or researchers to obtain more realistic data, such as in setting block generation intervals and designing neighbor node selection algorithms.
