DigiDollar — a decentralized USD stablecoin on DigiByte
DigiDollar is a USD-pegged stablecoin issued natively on the DigiByte blockchain, live on mainnet since it activated on July 17, 2026 (block 23,869,440). Unlike custodial stablecoins that hold dollars in a bank, DigiDollar is backed by DGB locked in on-chain collateral vaults secured with Taproot time-locks. There is no bank account, no custodian, and no liquidation engine — collateral stays locked until the vault owner redeems.
Price data comes from a decentralized roster of oracles that sign with MuSig2 aggregate signatures, so no single party can forge a feed. The result is a dollar-denominated unit of account that inherits DigiByte's proof-of-work security, has run continuously since 2014, and can be audited address by address — every node recomputes the collateral behind every DigiDollar every block. The oracle set that secures the peg is the same fleet serving private sync — one piece of infrastructure, two sovereignty guarantees.
