ETHCC Brussels was one of the clearest international appearances of node101 in 2024. The week was not limited to simple attendance. It became a multi-layer presence where node101 showed up across hackathons, community partnerships, bounty programs, and Cosmos-oriented side events. Instead of being visible in only one format, node101 appeared across both the Ethereum-facing builder environment and the modular and Cosmos-focused event layer around Brussels. The travel planning for the week also shows a large on-site presence from node101, with 10 team members joining the ETHCC trip.
node101’s ETHCC Brussels Presence
What made the week strong was the breadth of that presence. node101 joined Lambda Hack Week 2 as a Developer Community Partner, supported the hackathon as one of its 20+ sponsors, launched a dedicated Cosmos bounty track with $4,000 worth of ATOM, and also appeared as a Developer Community Partner at Nebular Summit, a Cosmos- and modular-focused conference in Brussels. Taken together, this positioned node101 not only as a builder team, but as a community actor capable of bridging Ethereum, zero knowledge, modular infrastructure, and the Cosmos stack in the same international event window.
Lambda Hack Week
Lambda Hack Week 2 was one of the main hackathon surfaces of the ETHCC Brussels week, and node101 showed up there with both ecosystem presence and direct incentives. The event ran from July 6 to 9 in Brussels as a four-day hacking week for 200 participants, with tracks including Interoperability, LambdaWorks, ZK L1 & L2 Apps, and On-chain Game Development. node101 joined as a Developer Community Partner and was also listed among the sponsors alongside names such as Aligned, zkSync, and Celestia.
node101’s clearest contribution inside Lambda Week was the Cosmos bounty program. The team offered $4,000 in ATOM to projects that combined Cosmos SDK, IBC, and zero knowledge in meaningful ways. The bounty was designed to bring more ZK developers into the modular ecosystem and encouraged builders to create Cosmos SDK projects with ZK, integrate Cosmos SDK into hackathon projects, add IBC to ZK applications, or bring ZK functionality into existing Cosmos chains. The prize structure was $2,000 for first place, $1,250 for second, and $750 for third.
The logic behind this bounty also matched node101’s wider technical direction. The announcement explicitly tied the bounty’s motivation to Photon Bridge, the node101 project that connected Mina and Celestia and won first place at the previous Lambda Class hackathon. That made the Brussels appearance feel continuous rather than isolated: node101 was not just sponsoring a challenge, but extending a builder story that had already produced one of its strongest hackathon wins.
Nebular Summit
Nebular Summit represented the Cosmos and modular side of node101’s Brussels presence. Held on July 12–13 at La Tricoterie in Brussels, the event was framed as a developer conference around modular appchains and the Cosmos stack, and node101 joined as a Developer Community Partner. The event invited participants into technical talks, workshops, panels, debates, and investor speed-dating sessions, and was promoted as a place to connect with 600+ developers and founders.
This made Nebular an important complement to Lambda Week. If Lambda represented the build-and-ship energy of the Brussels week, Nebular represented the ecosystem and narrative layer around Cosmos and modular infrastructure. node101’s appearance there showed that its role in Brussels was not only hackathon-facing, but also community-facing, helping connect the Cosmos stack to a wider international builder audience.
