EthCC is the largest annual European Ethereum event focused on technology and community. Join us every year for four intense days of conferences, networking, and learning.
EthCCValues
These core principles guide our mission and shape the EthCC experience.
Radical Inclusion and Diversity
We actively invite and celebrate the full spectrum of humanity. Every individual brings unique perspectives and ideas, and we believe our community is strongest when these differences are embraced. We don’t just allow diversity—we thrive because of it. Opinions are not actions though: respect others’ beliefs systems and be open to question yours.
Relentless Pursuit of Excellence
Excellence isn’t just a goal—it’s a habit. We commit to delivering the highest standards in everything we do, from the smallest details to the most complex systems. Continuous improvement is at the core of our operations. We hold ourselves accountable to the community we serve.
Fostering Collaboration & Knowledge Sharing
Knowledge, when hoarded, is stagnant. When shared, it fuels progress. We foster a culture of open collaboration where ideas flow freely, sparking new insights and innovations. By removing barriers to information, we create an ecosystem where learning and growth are limitless, and always promote collaboration over competition.
A Conference with a Twist
We aren't conventional and want to stay weird. EthCC is not just a conference, it’s a playground. We aim to surprise every year, with a small detail, a human experience.
Purpose Over Profit
Our mission transcends profit. As a non-profit, we prioritise the needs of the community and the growth of the ecosystem over financial gain. We operate with transparency and integrity, reinvesting the surplus back into the projects, people, and communities that will shape the future. At our core, we exist to serve the Ethereum community, not exploit it.
Real World Connections
In a world increasingly driven by digital interfaces, we cherish the power of human connection. EthCC brings people together in meaningful ways, creating real-world bonds that go beyond the virtual. Embrace the awkwardness of real life new interactions, help strengthen the very fabric of our community and foster relationships that drive lasting impact.
Ethereum-Centric at Our Core
At EthCC, our focus is firmly on Ethereum and its ecosystem. We champion projects that drive Ethereum’s growth and uphold its core values of decentralisation, transparency and empowerment. While our foundation is Ethereum, we welcome projects from other ecosystems that align with these principles, contributing to the broader vision of a decentralised future.
Pragmatic Pioneers of Web3
We are builders, not dreamers. While we embrace the revolutionary potential of Web3, we are grounded in real-world action. We push forward with a practical, results-driven mindset, ensuring that the future we envision for blockchain technology is accessible, sustainable and delivers tangible benefits for all. We are the bridge between ambition and implementation.
