An Ethereum Working Group consisting of wallet developers, security firms and the Ethereum Foundation’s Trillion Dollar Security Initiative today launched an open standard designed to end blind signing — a structural flaw that has contributed to billions in user losses, including the Bybit hack. Ethereum Foundation’s Trillion Dollar Security Initiative is taking an active role as a credibly neutral steward of the Clear Signing registry. Across major exploits in crypto and blockchain applications, the final step often isn’t a bug in code, but a user approving a transaction. Even when phishing or an infrastructure compromise initiates the breach, the last…

A semi-regular gathering of Ethereum core devs from various client teams, or interop, recently took place in Svalbard, Norway. Over the week-long event, teams focused on hardening and preparation for the next upgrade, Glamsterdam. Several important milestones came out of the week, including: 200M gas limit floor established: Credible post-Glamsterdam target derived from convergence of ePBS, BAL optimizations, and EIP-8037 repricingePBS stabilized: Multi-client Glamsterdam-devnet running with external builders pipeline tested end-to-end across nearly all clientsEIP-8037 finalized: Fixed cost_per_state_byte adopted; full repricing numbers delivered by Friday on bal-devnet-6Hegotá groundwork laid: FOCIL prototypes are functional; native AA requirements were scoped; the multi-client…

This past week, just over 100 Ethereum core contributors gathered above the Arctic Circle — in Longyearbyen, Svalbard — for the Soldøgn Interop: a week of intense work on the Glamsterdam network upgrade. Soldøgn followed last year’s Berlinterop, but returned to the format used by Amphora 🏺, Edelweiss 🏔️, and Nyota ✨: a single-track week of focused, multi-client progress toward a specific upgrade — in this case, hardening Glamsterdam. By Friday, the group had delivered on its three core goals: alignment on a post-Glamsterdam gas limit floor of 200M, stable ePBS implementations running with external builders, and final EIP-8037 repricing…

TL;DR: We are excited to announce that applications are now open for the seventh cohort of the Ethereum Protocol Fellowship (EPF7). EPF provides a pathway for aspiring protocol developers to make meaningful contributions to Ethereum. In each cohort, a diverse group is assembled to work toward advancing Ethereum’s roadmap focused on the core properties that define Ethereum; censorship resistance, open source, privacy, and security. This includes the development of client implementations, testing and specifications, and engaging with the latest core protocol research. With an overarching goal of finding placement for fellows in R&D teams working on core protocol development, EPF…

Corporations, US presidential candidate Mitt Romney reminds us, are people. Whether or not you agree with the conclusions that his partisans draw from that claim, the statement certainly carries a large amount of truth. What is a corporation, after all, but a certain group of people working together under a set of specific rules? When a corporation owns property, what that really means is that there is a legal contract stating that the property can only be used for certain purposes under the control of those people who are currently its board of directors – a designation itself modifiable by…

In the first part of this series, we talked about how the internet allows us to create decentralized corporations, automatons that exist entirely as decentralized networks over the internet, carrying out the computations that keep them “alive” over thousands of servers. As it turns out, these networks can even maintain a Bitcoin balance, and send and receive transactions. These two capacities: the capacity to think, and the capacity to maintain capital, are in theory all that an economic agent needs to survive in the marketplace, provided that its thoughts and capital allow it to create sellable value fast enough to…

In the first two parts of this series, we talked about what the basic workings of a decentralized autonomous corporation might look like, and what kinds of challenges it might need to deal with to be effective. However, there is still one question that we have not answered: what might such corporations be useful for? Bitcoin developer Jeff Garzik once suggested that one application migh be a sort of decentralized Dropbox, where users can upload their files to a resilient peer-to-peer network that would be incentivized to keep those files reliably backed up. But aside from this particular example, what…

The purpose of this post is not to say that Ethereum will be using Slasher in place of Dagger as its main mining function. Rather, Slasher is a useful construct to have in our war chest in case proof of stake mining becomes substantially more popular or a compelling reason is provided to switch. Slasher may also benefit other cryptocurrencies that wish to exist independently of Ethereum. Special thanks to tacotime for some inspiration, and for Jack Walker for improvement suggestions. Proof of stake mining has for a long time been a large area of interest to the cryptocurrency community.…

I first wrote the initial draft of the Ethereum whitepaper on a cold day in San Francisco in November, as a culmination of months of thought and often frustrating work into an area that we have come to call “cryptocurrency 2.0″ – in short, using the Bitcoin blockchain for more than just money. In the months leading up to the development of Ethereum, I had the privilege to work closely with several projects attempting to implement colored coins, smart property, and various types of decentralized exchange. At the time, I was excited by the sheer potential that these technologies could…
