Staking is the primary way of accruing passive income as a Babylonian. Staking in plain English is the act of putting in something with the expectation of getting something in return. In Babylon this definition holds but to add the thing expected in return is dependent on the success of Babylon (so it’s adapted for long-term ROI). The increase in your stake translates into a constantly falling cost basis converging to zero. This means that even if the market price of $BBY drops below your initial purchase price, given a long enough staking period, the increase in your balance should eventually outpace the fall in price.
When one stakes, their $BBY is deposited in the treasury and in an equal ratio of 1:1 sBBY is automatically deposited in their wallet. The sBBY is non-transferable and having this means you will receive the rebasing rewards of the protocol every 8 simanus (8 hours in Babylon).
Interestingly, just as the feast of Marduk is being done. Once someone unstakes their sBBY and burns it for BBY, their BBY would be given to them but (having the Babylonian numbering system be in sexagesimal, that is in base 60) they would only be permitted to stake again at a random hour between 1 and 60 hours from then (would generally be just 2 if you're a half decent person). That is of course if Marduk permits!
