The Open
Source Orchestra

Music as sanctuary. Like Ethereum, it is owned by no one — decentralized, and open to permissionless contribution.

The story begins

Movement I

The Invitation

There are no auditions here. No gatekeepers tuning the door. No guest list, no wrong instrument, no one waiting to tell you that you aren't ready. If you feel the pull toward the music — you already have a seat in the orchestra.

Radical inclusion is not a policy we wrote down. It is the opening chord. The person who has played for thirty years and the person who has only ever hummed in the shower — the orchestra needs both, exactly as they are.

“You don't join the Open Source Orchestra. You notice you were always in it.”

Movement II

The Oldest Protocol

Long before blockchains, mankind forked the original protocol: a gathering — often in a circle, in a city square or an open field — of chanted, rhythmic melodies dancing to the harmonies of instruments of all kinds. That ancient tradition is the simple inspiration for the Open Source Orchestra.

No one owns the podium. Stewards tend the space like gardeners — steering, never conducting. No hierarchy deciding whose part matters. We listen to one another — and we all conduct this space together. Everyone who shows up is a contributor. Not an audience. Contributors.

This is not a brand. It will never be a logo, a product, or a company. It is a movement, a philosophy, a way of being — principles and a manifesto carried from gathering to gathering, told and retold, never owned.

And the score is open. You don't need a Devcon to begin — a fire circle, a rooftop, a hackathon, a city square will do. Fork the orchestra wherever you are, and it sounds there too. That is the oldest protocol, working as designed.

“The whole is infinitely greater than the sum of its parts — because the parts are listening.”

Movement III

The Values We Play

The Open Source Orchestra is Ethereum's values, expressed not in a whitepaper but in a room full of people making sound together. This is the manifesto of the Devcon 8 Music Stage — carried exactly as it was written:

Word for word · the Music Manifesto

♪  Music Manifesto  ♪

Music as sanctuary. This stage is a living expression of Ethereum's core principles — decentralization, censorship resistance, open-source collaboration.

Like crops grown in shared soil, the music here belongs to the community. Every voice is a node. Every sound, a contribution.

Open Source Music
Every voice is a node
Sounds of Consensus

  • Censorship Resistance:  The Music Space has no owners — stewards steer, but never gatekeep. "Conductor-less".
  • Open Source:  Creative Commons
  • Private / Public:  Every sound is self-owned — pluralistic privacy is power when private individuals play together in public.
  • Secure:  We cover the atmosphere and protect the vibe of the community within a higher frequency

The Music Stage remains by and for the community.
There isn't room for every artist to have a slot, but there is infinite room if we play together, letting the music spread as openly as knowledge itself.
We steward this stage like we steward a garden. The instruments are permissionless. The stage is a sanctuary.

“Pluralistic privacy is power — private individuals, playing together in public.”

The official Devcon 8 India artwork — the Gateway of India under a sky of ETH diamonds. From the Music Space Committee deck.

Welcome, traveler. Devcon 8. Mumbai. The biggest gathering of the Ethereum family — and in 2026 the incredible musicians of India joined the circle. The Open Source Orchestra was there, 3–6 November 2026: not on a stage above you, but in a circle beside you.

The orchestra has walked this road before — born at ETH Prague in 2022, alive in the circles of Devcon 6 Bogotá and Devcon SEA. Each gathering passes the song to the next. Mumbai was the biggest circle yet: about 35 artists, four days, one open circle.

The Devcon Music Space brought together live musicians & DJs for four days of open improvisation, curated performances, and real-time collaboration — turning the space into a stage for shared musical experimentation. It embodies Ethereum's values of openness, permissionless participation, and collective creation, through the universal language of music.

The stage was Sanctuary Tech — circular and non-directional. There is no “front.” Performers face one another; the audience wraps around the music. Warmth, belonging, refuge — a home with clear boundaries and an open invitation.

And the orchestra itself? The orchestra is whoever shows up.

♫ The gatherings are permissionless jams

Bring an instrument. Bring your voice. Bring a drum, a laptop, a kalimba, a poem — or bring nothing but yourself. That is more than enough.

  • A community backline — drum kit, guitars, keys, a percussion circle, DJ decks — shared by all
  • Tabla, harmonium, dhol, bansuri — India's classical traditions at the heart of the Mumbai edition
  • Live coders and algoraves — software engineers programming music in the open
  • Everyone who shows up is part of the orchestra — we all conduct this space together

Answer the Call

For Devcon 8, participation in the Devcon Music Space began with an open call for musicians, DJs, and volunteers. Applications were reviewed by the Music Space Committee, which curated the program and assigned performance slots across the four days of Devcon. Volunteers helped operate the space and created a welcoming, collaborative environment. For Devcon 9 in Lisbon the door is already open: join the circle.

  1. September – October 2026

    Application & Selection

    Apply as a musician, DJ, or any musical performance. The Music Space Committee curates the lineup and assigns performance slots and volunteer roles.

  2. November 1–2, 2026

    Pre-production

    Volunteers arrive early to co-create the Music Space — setup, sound checks, rehearsals, and preparing the experience for Devcon.

  3. November 3–6, 2026 ✅

    Devcon 8 — it happened ✅

    We performed, jammed, collaborated, and connected through four days of live music, DJ sets, and Open Source Orchestra sessions with musicians from around the world.

🎻 Devcon 8 happened ✅ (3–6 Nov 2026) — its Open Call is closed, the circle never is

The Mumbai applications are closed, but the circle never is. Step into the Garden Circle — meet every steward and artist — or walk with us toward Lisbon: join the circle for Devcon 9.

Interlude

Find Your Seat

Solo artists and bands, DJs and live coders, vocalists and dancers, VJs and live painters — every contributor sounds different, and the orchestra is richer for it. There is no small part — only parts that make the whole possible. Which one is yours?

  • Lead
    You carry the melody — you start the songs, name the visions, say the thing out loud first.
  • Harmony
    You make others sound bigger — supporting, bridging, deepening every line you touch.
  • Rhythm
    You keep the heartbeat — the organizers, the builders, the ones who hold the space steady.
  • Texture
    You color the air — art, story, code, care. The details that turn a song into a place.

Encore · Road to 2027

Every major Ethereum gathering at heart

🦄 The Road to Devcon 8 is complete ✅ — and the road to 2027 is already alive

Devcon 8 happened in Mumbai, 3–6 November 2026. Now the Open Source Orchestra walks toward every major Ethereum gathering of 2027 with the whole circle at heart, all the way to Devcon IX in Lisbon, the ukulele's road home: the little machete of Madeira sailed to Hawaiʻi in 1879.

  1. 12–15 AprEthCC[10] · Cannes 🇫🇷
  2. 14–16 AprETHGlobal Cannes · Cannes 🇫🇷
  3. 14–16 JunETHConf + ETHGlobal New York · New York 🗽
  4. 23–25 AugETHGlobal Tokyo · Tokyo 🇯🇵
  5. 12–14 OctDevcon IX · Lisbon 🇵🇹, CCL – Lisbon Congress Centre
  6. 13–15 OctETHGlobal Lisbon · Lisbon 🇵🇹

These are the organisers' announced dates (as of 14 November 2026; if an organiser moves a date, their site wins). None of them is a promised Open Source Orchestra slot, stage or budget: we hope to play open circles at each of them. Devcon 8 lives on in the Mandala Room and the room you let us build.

🎻 The Open Source Orchestra is open for forking and hosting.

No auditions, no gatekeepers, no wrong instrument: the orchestra is whoever shows up. Send us your invitations (host a music circle at your event, hackathon, pop-up city or venue) and/or your contributions (music, code, stewarding, sound, translation, photos). Every contribution is equal, one voice each; a circle of at least three stewards answers within 14 days, and open jams never need an application.

🤝 Invite us · join the circle → 🍴 Fork it on GitHub ↗ ✉️ Write to us
