## Content

Born from the extensive work completed by Meta for their Diem (formerly Libra) project, both Aptos and Sui are backed by experienced teams and seek to use their product development expertise to solve the problems current L1s face. These problems include safety and privacy concerns, as well as structural scalability issues. To help solve these issues, both L1 blockchains utilize the new smart contract programming language: Move. Move, originally developed for Diem, displays innovative improvements on current alternatives, and promises both an unmatched level of smart contract security, as well as a low migration cost for Solidity or Rust developers.
