KT said in a statement on Thursday that the company has agreed to collaborate with IBK and Bellsoft, an unmanned money exchange kiosk operator, to jointly develop and launch a blockchain-based currency exchange service.
"We are planning to demonstrate KT's blockchain platform's capabilities and excellence in various financial services sectors by jointly launching IBK's unmanned exchange reservation service," KT's Blockchain Business Center head Yoo Yong-kyu was quoted as saying.
Through the blockchain-based money exchange service, customers can make reservations to use the money-changing service using a smartphone app or a PC before they withdraw money from unmanned kiosks located at airports, bus terminals, hotels and shopping malls.
KT said that it has specially developed a blockchain platform that would process the transfer of transaction data between the main network of IBK and Bellsoft's unmanned kiosks. The blockchain technology monitors the whole process to prevent double transactions and malfunctions involving counterfeit money and corrupted data.
The blockchain-based currency exchange service will be tested on by IBK's technology demonstration laboratory before it is commercialized in 2020.
