Understanding them is a core part of understanding how "block transactions" are handled at anything beyond a surface level.

Whether you have major ties to a blockchain system or just want to know more about how they work, understanding the differences between proof of work and proof of stake is vital if you want to get your head around blockchain networks as a whole.

About Consensus Mechanisms
Both the proof of work and proof of stake are consensus mechanisms, systems that blockchain and crypto networks use to validate transactions.

This system is meant to ensure that there can be no third-party tampering with the system - even if one person manages to cheat the system, the consensus mechanism will kick in and realize that the numbers do not match up.

These two mechanisms have been around for a while but have only gotten more and more noteworthy as crypto has gradually become the most popular use of blockchains. Through proof of stake and proof of work, blockchains can ensure that only legitimate transactions go through.
