Crypto and Payments Firm MobileCoin Launches Stablecoin -- 'Electronic Dollars'

Privacy-focused cryptocurrency and payments firm MobileCoin, in collaboration with stablecoin platform Reserve, has launched a stablecoin dubbed "Electronic Dollars" (eUSD). CoinDesk reports: According to MobileCoin, eUSD is backed by a basket of other stablecoins, namely, USD coin (USDC), Pax dollar (USDP) and trueUSD (TUSD). Each transaction is said to be encrypted using end-to-end zero-knowledge encryption. In other words, only the transacting parties can see their own transactional data, thanks to encryption that uses zero knowledge proofs (a way of proving something without revealing sensitive information). The stablecoin eUSD is built on the MobileCoin blockchain, which, according to MobileCoin, is optimized for mobile devices. Apparently, MobileCoin was originally designed for integration with encrypted mobile messaging app, Signal. Consequently, eUSD will inherit the features of MobileCoin's native cryptocurrency, MOB, although eUSD users will pay transaction fees (a flat $0.0026 per transaction) in eUSD and not MOB. The eUSD relies on what seems to be a centralized governance structure where the MobileCoin Foundation acts as the primary governing body. The foundation elects "governors" who are authorized to mint and burn eUSD. The stablecoin's collateral is held in a popular Ethereum multisignature (multisig) wallet called Safe (formerly "Gnosis Safe"). New eUSD is only minted after governors confirm an equivalent amount of collateral has been transferred to the Safe wallet. "Anybody can inspect the contract holding this basket [of collateral], to see what the current balances are. It's a Gnosis safe, which is also one of the most highly regarded contracts on Ethereum for holding assets," Henry Holtzman, MobileCoin's chief innovation officer explained during an interview with CoinDesk. Similarly, if a user redeems eUSD, the token is "verifiably burned" and governors release the corresponding collateral. Verifiable burning is when burned eUSD is sent to a "burn address" that renders it "visible" for transparency purposes, "but unspendable." However, everyday users won't typically engage in burning and minting. An individual seeking eUSD would simply purchase it on an exchange. Approved liquidity providers (LPs) would be the ones minting large amounts of eUSD. To our knowledge, no project has created a native stablecoin with privacy properties, which is a first-class citizen in the ecosystem, and which never requires the use of 'non-private' transaction technologies to use normally. In short, no one has yet actually created a private digital dollar," MobileCoin stated in the eUSD white paper. Holtzman said that eUSD uses a "reserve-auditor" program that "connects to the Safe wallet via an application programming interface (API) and verifies that each newly minted eUSD has a corresponding amount of collateral in the wallet." Holtzman added: "We'll release it all open source. So if you want to run your own copy [of the reserve auditor], you can. You can examine it to make sure we really are backed exactly as we claim," Holtzman told CoinDesk.
