Modular Summit 3.0 — a three-day conference for 4,000 people

SILO Brussels is one of the largest event venues in the city, with 9 distinct spaces under a single industrial roof. In July 2024 it hosted Modular Summit 3.0 — the largest blockchain conference ever held in Brussels — and the way the event used the building is a useful illustration of what SILO is built to handle.

Hosting a three-day conference for 4,000 people in Brussels

The crown jewel of SILO's spaces is Meudon, a 1,321 m² industrial hall with soaring ceilings and an open-plan volume that absorbs almost any stage configuration. Alongside it sits Navy's, a 660 m² second hall with industrial columns and large windows over the canal. Together they form the two largest spaces in the venue, and they can run simultaneously when the programme calls for it.

Modular Summit 3.0 used both halls in parallel as twin main stages. Over the three days from 11 to 14 July 2024, more than 4,000 international delegates and 115 speakers moved between Meudon and Navy's, with smaller rooms across the building hosting breakout video sessions. It was the largest blockchain conference ever held in Brussels, and a clear demonstration that SILO can host events in the multi-thousand-attendee range without spilling into satellite venues.

Arrival by boat — directly on the Brussels Canal

SILO sits directly on the Brussels Canal, a feature that's almost unique among Brussels event venues. The waterfront location means guests can be brought to the venue by boat, turning the arrival itself into part of the experience rather than a logistical formality.

For Modular Summit 3.0, this is exactly how the VIP arrival was handled: delegates crossed the canal by boat to reach the venue entrance, replacing the usual taxi-and-cloakroom queue with a memorable opening moment. The same canal access can be used for product launches, brand activations and gala arrivals where the entrance needs to feel like an event in itself.

A facade you can make your own

SILO's facade and entrance are not a fixed backdrop — they're part of the canvas. The venue accommodates large-scale facade dressing, branded structures at the entry, lighting animations and built installations, so the building itself can be styled to match the event's identity before guests ever step inside.

Modular Summit pushed this hard. A crane lifted a full container, wrapped in event branding, into place at the venue entrance — a piece of arrival staging that turned SILO's facade into part of the conference's visual identity. The same flexibility supports everything from projected logos and lit signage to full custom-built entry sequences.

Multi-track orchestration without leaving the building

With 9 separate spaces under one roof, SILO is designed for complex multi-format events that would normally require multiple venues. Main stages, parallel programmes, breakout studios, catering areas and open-air chill zones can all run simultaneously in the same building, without busing guests between locations.

Modular Summit 3.0 used five distinct spaces in parallel for the full three days:

The venue converted from conference mode to reception mode and back across the day without anyone leaving the building.

Broadcast-ready production infrastructure

SILO's industrial structure was designed with heavy production loads in mind: rigging points, three-phase power, internet bandwidth, loading access and back-of-house circulation that comfortably absorb full broadcast crews and equipment trucks.

For Modular Summit, production partner GSP2 deployed 20 cameras, 10 m² of LED screens, 55 high-frequency channels and a continuous live stream across all three days — the kind of TV-grade setup that needs a venue with the right power, the right rigging, and the right back-of-house. The same infrastructure has supported product launches, fashion shows, brand campaign shoots and televised galas elsewhere in the venue's calendar.

A canvas for unconventional formats

The industrial volumes, raw concrete, high ceilings and natural light give organisers an unusually flexible canvas. Stage designs, scenography and creative formats can be built into the venue without fighting an existing finish — the building tends to amplify a creative direction rather than constrain it.

Modular Summit used this latitude for live mind-mapping illustrators, who worked on the venue walls in real time, summarising every session as it happened. Few conference centres can host that kind of format: it needs wall space, sightlines, and lighting flexibility that SILO offers as standard.

Featured speakers

The line-up included Mustafa Al-Bassam (founder, Celestia Labs), journalist and podcaster Laura Shin, and Sandeep Nailwal (co-founder and COO, Polygon Technology), among 115 distinguished names from across the modular blockchain ecosystem.
