Quant launches Overledger Network 

DOWNLOAD THE UPDATE

Today marks a huge milestone in Quant’s history – the launch of Overledger Network

The release of Overledger Network is the culmination of almost two years’ work. In June 2020, we launched the Overledger 1.0 testbed network. Hundreds of community members and developers helped to test and develop multi-DLT applications (mDApps), giving feedback on the network, and, as a result, we made major improvements to our technology. 

Now, with today’s launch of Overledger Network, developer mDApps which migrate to Overledger 2.0 will be able to now use, initially, our distributed network of Remote Connector Gateways (RCGs) around the world to carry out transactions on Bitcoin, Ethereum, and Ripple. These will be continuously rolled out and added to the Overledger Network in a phased way with all transactions distributed by an algorithm which will weigh the traffic against the cost, accuracy and reliability of each gateway. The Overledger Network allows Enterprise customers to host gateways to interoperate and unlock private digital assets and permissioned DLTs to the rest of the world.

“We’ve delivered a huge volume of enhancements to Overledger 2.0 in 2021, but the one we’re most proud of is Overledger Network,” said Gilbert Verdian, CEO, Quant. “Since launching our testbed network in 2020, we’ve listened to our community and taken on board their recommendations. As a result, we’ve created an architecture that’s more robust, scalable, and user friendly. We can’t wait to see the response to Overledger 2.1.”

2021 Achievements

50% Quant team has grown by over 50% and will continue to do so 

OVL1.0 to 2.0 Release schedule accelerated, moved to much more frequent automated updates
– Previously, last major update was seven months, then in early 2021 moved to three months (Jan and March)
and then to monthly (April and May). We’re now moving to fortnightly releases. 

2.5X Overledger is now 2.5x bigger (April)  

2.0 Re-engineered the entire 2.0 architecture

Open API 3.0 for easy integration into developer workflows

OAuth 2.0 for single sign on for enterprise customers    

Cloud Native Scalable and resilient already, now deployable automatically 

New OVN API
