Bonded Proof-of-Stake (BPoS)

Basics

• "In Bonded Proof-of-Stake protocols (BPoS) such as Cosmos or IRISnet, both the validator and its delegators are directly punished.” As noted in Bakerz blog, slashing can occur in cases where there’s a “liveness fault” detected on Cosmos or IRISnet. This occurs when the “validator node does not participate in the network consensus for a long time and misses several blocks.”
• “In some protocols,” Bakerz noted, the “validator can also be jailed, a process prohibiting [them] from re-entering the networks for a certain period of time.” Meanwhile, in BPoS) protocols such as Cosmos and IRISnet, the “delegators are also at risk of punishment,” so POS Bakerz recommended that users “carefully choose [their] validator.”
