Road To Devcon - II
Art, Culture & Ethereum in India
In 2026, Ethereum turns 11. Eleven years since a genesis block turned an experiment into the base layer for a global builder economy. To mark it, we're running 11 weeks of Build Battles, one for every year of Ethereum's life, every weekend as part of Road to Devcon.
New dev challenge drops every weekend, welcome to the second chapter.
From the intricate lines of Warli and Madhubani murals to the oral traditions of Baul singers in Bengal and Carnatic music lineages in the South, India's cultural heritage lives in its communities. For generations, master artisans and vocalists passed down their craft through the Guru-Shishya tradition. Yet, in the digital age, these local creators face relentless exploitation, mass-produced knockoffs, and middlemen who siphon off earnings while leaving traditional heritage unprotected.
Ethereum acts as a digital Pattachitra, an immutable, public canvas where regional folk art, traditional music, and cultural IP gain cryptographic provenance, direct royalty enforcement, and global reach.
This weekend, you step up as Digital Scribes of Heritage, connecting India’s folk creators directly to global Web3 collectors.
