A proof protocol refers to a mechanism used in blockchain networks to validate transactions and secure the system. It ensures that participants agree on the state of the ledger without needing a central authority.There are different types of proof protocols, with Proof of Work (PoW) and Proof of Stake (PoS) being the most notable. In PoW, miners solve complex mathematical problems to validate transactions and add new blocks to the chain. This process consumes significant computational power and energy.In contrast, PoS allows validators to create new blocks based on the number of coins they hold and are willing to “stake” as collateral. This approach aims to be more energy-efficient and can reduce the risks of centralization.Overall, proof protocols play a crucial role in maintaining the integrity and security of a blockchain by incentivizing participants to act honestly. They provide a framework for reaching consensus and ensure that the system functions smoothly without the need for intermediaries.
