Upbit upgrades matching engine to process KRW 1 quadrillion trading volume
South Korea’s largest cryptocurrency exchange Upbit has enhanced its matching engine — which matches buy and sell orders from users on the exchange — to be able to handle a daily trading volume of KRW 1 quadrillion (approximately $757.3 billion), according to local news outlet Kyunghyang Games.

Because the crypto market operates nonstop without limits to time or borders, having a solid infrastructure that can seamlessly handle large amounts of data is crucial. Upbit has thus been working on its so-called “Stairway to Heaven” project for the past two years to upgrade its trading infrastructure, including its matching engine.
Constant upgrades
The Stairway to Heaven is a long-term project in which Upbit’s operator Dunamu has invested a total of KRW 10 billion (approximately $7.6 million) to adjust to the rapidly advancing crypto industry and improve the performance of the entire market system. The upgrades
The main goal of the project is to upgrade Upbit’s matching engine to be cloud-native and horizontally scalable. The engine is now capable of supporting more than 40,000 transactions per second — a 25-fold increase from the previous version of the engine — allowing it to respond efficiently to surges in user traffic. In the event of a traffic spike, the system can handle more than 100,000 transactions per second with additional servers, the exchange said.
“Unlike the way traditional finance approaches ledger management, our cloud-native architecture allows us to flexibly respond to surges in traffic,” Upbit said. “We will continue to make various system improvements to offer a stable investment environment.”
Elevating the user experience
In addition to upgrading its matching engine, Upbit has recently revamped its UI/UX to include price chart updates by second increments and an overview of profits and losses. The exchange plans to continue its multifaceted efforts in service quality, security and investor protection to become a domestically and globally recognized exchange.
