  1. Thanks for the good overview, although I cannot quite get the race conditions example. In smart contracts you cannot call anything simultaniously, Transactions and functions calls are atomic, so you cannot put the transfer call within the withdrawal call. Once withdrawal finishes the balance is updated. Please, let me know if I am wrong

  2. It’s somewhat concurrent. The withdrawBalance function starts, then in-between, the transfer function is run. When the transfer function ends, the withdrawBalance function continues and then end. Because the withdrawBalance function hasn’t updated the state, it could give the user more than the coin/money.

    Liken it to running a function inside the main function in Rust or Go.

  3. This insightful article highlights common mistakes to avoid in smart contract development – it reinforces the importance of metaverse training to ensure robust and secure implementations.
