# Advance Proof-of-Stake (POS) is POA

ANB give importance to tight security and data protection.

Proof of stake (PoS) is a type of [algorithm](https://cryptodefinitions.com/dictionary/algorithm/) whereby a [cryptocurrency](https://cryptodefinitions.com/dictionary/cryptocurrency/) [blockchain](https://cryptodefinitions.com/dictionary/blockchain/) achieves distributed [consensus](https://cryptodefinitions.com/dictionary/consensus/). The concept of PoS is that the creator of the next [block](https://cryptodefinitions.com/dictionary/block/) (i.e., group of validated transactions) is selected based on specific criteria including the amount of and age of cryptocurrency they hold (i.e., their stake). In contrast, [proof of work (PoW)](https://cryptodefinitions.com/dictionary/proof-of-work-pow/) consensus algorithms require miners to solve computationally intensive mathematical functions to validate transactions and create new blocks.
