TBCASoft

TBCASoft is a blockchain technology company in Sunnyvale, California, building consortium chain platforms specifically for telecommunication carriers. The scenario it addresses is inter-carrier settlement and interoperability: cross-border mobile payments require billing, clearing and reconciliation inside each carrier's own network, and the traditional process relies on bilateral agreements and manual reconciliation. Its Cross-Carrier Payment System puts transaction records and clearing on one consortium chain, letting subscribers pay at overseas merchants directly from their mobile wallet and settle through carrier billing in their home currency.

The design is a non-mining consortium chain whose unit of account is a fiat-backed IOU crypto-credit model, avoiding token price volatility. The platform is layered so personal data stays behind carrier firewalls while on-chain records are anonymous to other participants. The CBSG Consortium founded in 2017 was launched by the company together with carriers including SoftBank; it entered a technology collaboration with IBM in 2019, and in February 2020 Asia Pacific Telecom and a US carrier completed proof-of-business transactions on live retail purchases. It is categorized as enterprise blockchain for the telecom sector.
