bDollar Bonds (bBDO) help to incentivize changes in BDO supply during both epoch expansion and contraction periods. For starters, the exchange rate for BDO to bBDO is 1:1, but bBDO to BDO ratio is dependent upon the mechanism as described here. When BDO's TWAP falls below 1 $BUSD peg, bBDO gets issued and can be bought with BDO at its prevailing price. Doing so takes BDO out of its circulating supply.
Contrary to early algorithmic, seigniorage stablecoin protocols, bBDO does not have expiration dates. All holders are able to redeem their bBDO for BDO tokens as long as the Treasury has a positive BDO balance, which typically happens when the protocol is in epoch expansion.
Simply by HODL-ing BONDS, you can also be use it to farm BUSD (by block) by participating in our Bonds LP Pool which is available at https://bdollar.fi/banks. It is also Recommended you fast track your bBDO/BDO Pool to yield BUSD using the created LPs and stake it over at bvaults.fi instead. This way you can gain on both capital gain as well as yield farming.
