What Is DigiDollar? DigiByte's Native Stablecoin, Explained
Most stablecoins are an IOU. A company holds dollars in a bank account somewhere, issues tokens against them, and asks you to trust that the dollars are really there. It usually works — until the bank has a bad week, the issuer gets a subpoena, or your address ends up on a freeze list you never knew existed.
DigiDollar takes a different path: it's a US-dollar-pegged stablecoin issued directly on the DigiByte blockchain, backed not by dollars in a bank but by DGB locked in on-chain vaults that anyone can inspect. No company in the middle. No account that can be frozen by the issuer. No trust required beyond the chain itself — a proof-of-work network that has run continuously since 2014.
How it works, in plain English
You lock DGB, you mint DigiDollar. To create DigiDollar, a user locks DGB into a collateral vault — a special on-chain construction secured by Taproot time-locks. The vault is deliberately over-collateralized: the DGB locked inside is worth substantially more than the DigiDollar minted against it, so the peg stays covered even when the DGB price moves.
There is no liquidation engine. This is the design choice that surprises people who know other collateralized stablecoins. Systems like MakerDAO auction off your collateral the moment its value dips below a threshold — which works, but means a flash crash can eat your position at the worst possible moment. DigiDollar's vaults don't liquidate. Your collateral stays locked under its time-lock until you redeem it yourself. The system leans on high collateral ratios instead of forced sales.
The price feed can't be forged by any single party. A stablecoin needs to know what a dollar is worth in DGB. DigiDollar gets that from a decentralized roster of independent oracle operators who sign price data together using MuSig2 — a signature scheme where the network accepts a price only when a quorum of oracles agrees. No single operator, including us, can move the peg.
The same nodes that secure the peg also serve your wallet. Here's a detail no other stablecoin can claim: the oracle node fleet that keeps DigiDollar honest is the same fleet serving privacy-preserving (BIP 157/158) sync to DigiByte mobile wallets. One set of infrastructure, two jobs, and anyone can verify both by checking the nodes' service bits. That's what we mean when we say real over hype — the plumbing does double duty in public.
What you'll be able to do with it
Send and receive dollars on DigiByte rails: fast blocks, negligible fees, and settlement on a chain with no company at the center. Hold a stable balance next to your DGB in the same wallet. And when vault management arrives in the DigiScope mobile wallet, open, mint against, and redeem a vault from your phone — with your keys, on your device.
Where things stand
DigiDollar activates with an upcoming DigiByte network upgrade — the change is now locked in and is scheduled to activate at block 23,869,440 (around July 17, 2026). It is live on testnet today, and the full technical design — vault construction, oracle roster, collateral parameters — is public. When mainnet activation completes, minting opens.
Want to be ready on day one? Our DigiByte learning quests — including “What is DigiDollar?” and “Pay with DigiDollar” — walk you through exactly how vaults, oracles, and the peg work, and pay you real DGB for learning it. That's the DigiScope way: understand the thing before you use the thing, and get paid for the effort.
