Ethereum Community Conference

Ethereum Community Conference (EthCC) is one of the largest annual gatherings of the Ethereum ecosystem, bringing together protocol developers, application builders, researchers, founders and investors from across the global Web3 community. It sits alongside Paris Blockchain Week, NRF: Retail's Big Show Europe and Finticipate as calendar anchors for the same audiences.

What happens

The core conference programme combines protocol-focused talks from Ethereum researchers and core developers with application-focused content from teams building on top of Ethereum and its rollup ecosystem. Parallel tracks cover protocol research, Layer 2 scaling, application development, decentralised finance, tokenisation, infrastructure and the broader ecosystem economy. Hackathons, side events, community gatherings and after-hours programming form a substantial part of the experience — much of the week's value is found outside the main conference venue, in the dense network of parallel events that operate during EthCC week.

Who attends

The audience reflects the global Ethereum ecosystem: protocol developers and researchers including representatives from the Ethereum Foundation and core development teams, application developers building on Ethereum and Layer 2 networks, founders and operating teams from Web3 companies across DeFi, infrastructure, identity, gaming and emerging categories, investors from crypto-native funds and increasingly traditional VCs with active Web3 books, and policy researchers working on crypto regulation. The geography is genuinely global with particularly strong European, North American and Asian representation.

Dominant themes

The Ethereum technical agenda dominates: Layer 2 rollup ecosystem maturation including optimistic and zero-knowledge approaches, account abstraction and its implications for wallet design and user experience, the continuing evolution of Ethereum core protocol including roadmap discussions of further scaling and decentralisation work, the role of decentralised finance under tightening regulatory environments globally, tokenisation of real-world assets and the practical bridge between Ethereum and traditional financial infrastructure, stablecoin regulation including MiCA implementation in Europe and US legislative developments, and emerging themes around AI agents transacting on-chain and the role of zero-knowledge cryptography in privacy and scalability.

Planning to attend

The distributed format means accommodation should be booked extremely early — supply tightens many months ahead of the conference in the host city. Visitors should plan to mix scheduled session attendance with substantial side-event exploration; the most valuable conversations often happen at community gatherings, hackathon spaces and informal meetups. The conference language is English. Cost of attending varies widely by host city but rises sharply for late-booking accommodation. International visitors should plan around the host country's visa requirements.
