The user must know the address and the interface of the Login contract beforehand. The user must spend some Ether to login because the contract relies on events that are logged to the blockchain (that is, they perform writes). With the transition to Ethereum 2.0, Ethereum plans to alter its core operating system, migrating to a system called proof-of-stake (PoS). Under a proof-of-stake model, any user who owns a minimum of 32 ETH could lock those funds in a contract, which then would earn rewards for solving computations needed to add new blocks to the blockchain. The Ethereum Foundation Grants Program is an ongoing and continually improving experiment into how the EF can best invest the Ethereum community’s resources for the highest long-term impact on the Ethereum ecosystem.
