"Decentralize everything and break down the silos between different blockchains" is the original intention of Polkadot, and it is also the vision that drives and promotes the development and implementation of Web3. In 2023, the Polkadot ecosystem has achieved significant results in both ecological development and technological innovation. The number of active developers in the Polkadot ecosystem is leading by a large margin, with over 500 projects signed under the W3F Grant program, covering every layer of the Polkadot technology stack. We also look forward to helping and supporting the growth of more startup teams, which is why we are organizing the Polkadot Hackathon 2023 Winter and offering over 300,000 USD in generous prizes to participants, the prize will be awarded in DOT.

After the meeting, Parity engineers and investment institution researchers will serve as mentors and enter the team group to provide guidance. The participating teams will propose development problems and needs based on the team's own project progress and technical structure. The mentors will provide substantive suggestions to the team to help them successfully incubate the entries!
