Technology overview
Summarize
Perspective
MobileCoin claims to focus on transactional anonymity (fungibility), ease of use, transaction speed, low environmental impact and low fees.[20] MobileCoin's mechanics build on Stellar (for consensus) and Monero (for privacy), using CryptoNote alongside zero-knowledge proofs to hide details of users' transactions.[2]
The MobileCoin company claims the cryptocurrency can facilitate decentralized payments for everyday transactions more quickly than most other cryptocurrencies.[21]
MobileCoin is a one dimensional cryptocurrency blockchain. Blocks use a consensus protocol originally developed for the Stellar payment network. Transactions are validated in SGX secure enclaves and are based on elliptic-curve cryptography. Transaction inputs are shown to exist in the blockchain with Merkle proofs of membership and are signed with Schnorr-style multilayered linkable ring signature, and output amounts (communicated to recipients via ECDH) are concealed with Pedersen commitments and proven in a legitimate range with non-interactive zero-knowledge proofs.[22][non-primary source needed]
Much of MobileCoin's technology comes from previous privacy focused cryptocurrencies like Monero and has been re-written in Rust for MobileCoin.[22][23][non-primary source needed]

Criticisms and controversies

Perspective
Signal Integration
The integration of MobileCoin wallets into the popular security focused messenger app Signal received criticism. Security expert Bruce Schneier, who previously praised the app, stated that this would bloat the app and attract unwanted attention from the financial authorities.[25]
Affiliations with FTX
MobileCoin began its affiliation with FTX in 2021 after FTX's sister company Alameda Research participated in MobileCoin's Series B investment round.[26]
In 2021, MobileCoin played a role in the financial collapse of FTX. A buyer on the FTX platform purchased a large amount of MobileCoin, artificially driving up the price, and then borrowed against it on FTX. The platform had to buy out the trader to protect itself, and survived thanks to a loan from sister company Alameda Research, resulting in a loss as great as $1 billion.[27]
In April 2022, MobileCoin cohosted a happy hour with FTX at Crypto Bahamas 2022.[28]
DAY v. BOYER
In 2017, a MobileCoin employee named Dustin Boyer offered to sell Pamela Day, an investor and former contestant of The Apprentice,[29] [30] 97,165 Mobilecoin tokens for the cost of $97,165. Boyer did not invest her money as promised but instead kept it for himself, comingled it with his own funds, and refused to return her money.[31]
In 2019, Day filed a legal action against Boyer to have the funds returned which was resolved in Day's favor in 2020.[32]
