Validators are crucial for securing blockchain networks by verifying and adding new blocks, earning rewards that support network integrity and provide passive income.
All validators are node operators; however, only validators actively participate in the consensus mechanism, leading to critical responsibilities for blockchain security.
When choosing a blockchain for validating, assess the consensus mechanism, staking requirements, and your technical expertise to find the best fit for your resources.
Potential returns for staking vary across platforms, with Ethereum 2.0 offering approximately 4-6% APY, and Cardano offering around 3%, among other blockchains.
