Algorand aims to solve the blockchain trilemma of achieving scalability, security, and decentralization by using a pure proof-of-stake protocol. It provides funding for projects building on its blockchain through grants and bounty programs to support use cases across research, education, communities, and finance. Examples of funded projects include Algorand Builder for interacting with smart contracts, an SAP connector from Mentat Innovations, and PlanetWatch's air quality ledger.
