Is BNB the same as beacon chain?

Could you elaborate on whether BNB, the native token of the Binance Smart Chain, is equivalent to the Beacon Chain, which is a component of Ethereum's transition to Proof-of-Stake? I'm curious to understand if there's any functional, technical, or even philosophical overlap between these two entities. Does BNB play a similar role in its ecosystem as the Beacon Chain does for Ethereum? Are they both designed to facilitate staking and consensus mechanisms? Or are they distinct in their purpose and implementation? Clarifying these points would greatly assist in my understanding of the current cryptocurrency landscape.
