​“A decade of transforming the world one block at a time.” On 30 July 2015 the Ethereum genesis block was mined. The internet quietly changed its aggregate state: finance became programmable, ownership digitised, memes tokenisable (sometimes against our will 😅). Ten years later the blocks still spark, and Vienna—city of coffee, modernism, and stubborn thinkers—invites you to celebrate the network’s first double‑digit birthday. Holding this POAP is proof you celebrated with us.
