How Do Staking Rewards Function Similarly to Interest Payments on a Bond?

Staking rewards are similar to bond interest payments in that they represent a periodic return on a locked-up principal (the staked amount). Both are a form of yield generated by committing capital.

A key difference is that bond interest is fixed or floating based on credit risk, while staking rewards are typically variable, based on network transaction fees, inflation, and the total amount of staked capital. Both are compensation for providing capital.
