**Proof of Stake (PoS)** is a way of achieving consensus by distributing [[dido:public:ra:xapend:xapend.a_glossary:v:validation|validation]] of a block of transactions based on the number of [[dido:public:ra:xapend:xapend.a_glossary:t:tokens|tokens]] held rather than by rewarding miners like [[dido:public:ra:xapend:xapend.a_glossary:p:proof_of_work]]. Consequently, PoS is a way of validating a block that requires far less energy that Proof of Work (PoW).  An important key aspect of PoS is including a degree of chance to the selection process to avoid a scenario where the richest users are always selected to validate transactions and consistently reap the rewards or to bias validation in their favour.
