DAO is an abbreviation of āDecentralised Autonomous Organizationā. This is basically an organisation that runs automatically on itself without any human interventions. The work is automatically excecuted through Smart contracts.
Proof of stake is a consensus mechanism used by some blockchain networks to achieve distributed consensus. In proof of stake, the creator of a new block is chosen in a deterministic way, depending on their stake in the network (how many coins they hold). This means that the more coins a validator holds, the more likely they are to create the next block and earn the block reward. Proof of stake is intended to be a more energy-efficient alternative to proof of work, which is used by networks like Bitcoin.
2 Factor Authentication is a double layer security measure. Most crypto exchanges use it. In order to log in, you not only need to enter a password, but also a code that you receive from the Google authenticator for example.
Proof of History (PoH) is a consensus algorithm used by the Solana blockchain platform to secure its network and validate transactions. It is a hybrid algorithm that combines elements of Proof of Work (PoW) and Proof of Stake (PoS) to achieve high levels of security and efficiency.
