Sub0 is the conference for developers building at every level of the Polkadot tech stack — from custom layer-1 blockchains to dApps and smart contracts, infrastructure, tooling, cross-chain interoperability solutions, and more. 

During this event, which took place in LX Factory in Lisbon on November 28th and 29th, 2022, Web3 Foundation, together with the teams of Apillon, Phala Network, Astar Network and Manta Network in representation of the entire Polkadot ecosystem brought together the global Polkadot developer community. 

Sub0 provided an open introduction to next-generation multichain networks, as well as a chance for existing Polkadot and Substrate developers to deepen their skills and connect with each other. There was separate content for experienced devs and those new to the ecosystem. Each attendee could follow their own path by attending more intimate talks and workshops in the Starter and Builder spaces. Those who are new could learn about the Polkadot tech stack, Substrate, Web3, blockchain and walk away with a clear understanding of the ecosystem. Experienced builders could dive into technical topics, build during workshops, see new blockchain SDK tools, and hear about the latest developments on Polkadot and beyond.

For this edition of Sub0, we wanted 50% of our audience to be new developers from outside of our ecosystem. This includes people who are not building on Substrate but are curious to learn more. By opening our doors to developers who are not (or only slightly) familiar with our tech, we can bring in more potential builders and expand our market reach and visibility.
