Sony has announced the development of a common database platform utilising blockchain technology for Mobility-as-a-Service (MaaS).
Independently developed by the Japanese electronics giant, the Blockchain Common Database (BCDB) features high-speed data processing to enable more than 7 million users per day to record and share anonymised travel history and revenue allocation.
Sony participated in the Blockchain Challenge Program, a MaaS initiative proposed by the Netherlands Ministry of Infrastructure and Water Management in 2019, and conducted a verification test of BCDB until the end of March 2020.
The BCDB is reportedly the industry’s first project to successfully realise the recording and sharing of large-scale movement history and revenue allocation by using blockchain technology for MaaS.
Blockchain technology is used to create networks where programmes and information are difficult to destroy or alter, and is well-suited for sharing and managing data and sensitive information.
BCDB has therefore made it possible to record and share information in a distributed ledger of the blockchain among various transportation operators, transaction processors and MaaSservice provides involved in MaaS.
According to Sony, BCDB, as a decentralised information platform, may contribute to the improvement of travel efficiency and measures for future smart city plans by analysing and utilising movement records and revenue allocation.
It is said to have scalability and is being calibrated for even faster data processing so that it can be used by transportation operators in large cities.
Furthermore, BCDB is also expected to be applied to the recording and sharing of various forms of sensor data related to the development of smart cities.
