How does proof of stake work? And What is Solerna

An incentive-driven educational platform called Solearna, which is based on Solana, resolves the complicated educational landscapes that have been failing for the past ten years. In the end, the users of Solearna, the students, are the primary users who we aim to support and empower with knowledge and insights. Solearna is an ecosystem designed for education. To make this possible, we need certifications that make use of NFT technology.

   A blockchain technology incentivizes traders to verify transactions by paying them in cryptocurrency for each valid verification. Proof-of-stake systems force traders to "stake" some of their bitcoin as collateral, which is subsequently locked up in a deposit, as a defense against fraud. A trader may lose some of their stake if they upload a transaction to the blockchain that other validators find to be invalid.

    The lowest amount that validators are typically permitted to stake is stated. Validators are free to stake as much as they like once the cap has been reached. In reality, the algorithm is more likely to select a trader whose stakes are higher. Let's use a straightforward scenario to demonstrate the point: suppose the blockchain has recently undergone a change that needs to be verified. To validate it, ten nodes volunteer, and they each stake one cryptocurrency. Thus, they each have a 10% probability of getting chosen for the job.
