Dear Polkadot ecosystem and DOT hodlers, 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. Following the success of sub0 Asia held in Bangkok, Thailand in March 2024, we are now bringing sub0 back to Europe. This event will take place in Barcelona, Spain in October 2024. sub0 Europe will continue to unite the global Polkadot developer community, providing an introduction to next-generation multichain networks and deepening the skills and connections of existing Polkadot and Substrate developers. In order to secure appropriate funding for the event we will be publishing a referendum in the medium spender track in a week and link the proposal document here.
