An X post from DigiByte says the DigiDollar protocol activates on the DigiByte mainnet at block 23,869,440 through a BIP9 soft fork, adding a decentralized stablecoin that is minted by time-locking DGB as collateral.
The change puts DGB into a new on-chain role beyond transfers, as the asset can now be locked to mint DigiDollar. That expands the network's economic design by linking stablecoin creation to DGB collateral, which could increase demand for holding and locking coins if users adopt the system.
The direct effect is availability, not proven usage. The longer-term significance depends on whether time-locking attracts meaningful collateral lockups after launch, since the activation itself confirms the feature is live but does not show how much DGB the market will commit to it.
