Russian payments firm Qiwi now estimates it could upgrade its core database to a distributed ledger system by 2021.
In an interview with Rambler News Service, a representative for the company said that this projection is in line with estimates that the full transition to any new technology takes about three years after a successful trial.
At this time, Qiwi representatives told CoinDesk in detail why the company is building a private blockchain system as part of a bid to increase the transparency, accountability and efficiency of its services.
In the latest remarks, Qiwi CTO Alexey Arkhipov provided more detail about how the ultimate switch to the system could take place.
Arkhipov said an interim period would likely be needed to transition its older, centralized database out of use, though he added that the two systems could operate side by side for as long as a year to avoid issues.
Arkhipov told the news source:
The leader in news and information on cryptocurrency, digital assets and the future of money, CoinDesk is a media outlet that strives for the highest journalistic standards and abides by a strict set of editorial policies. CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups.
