Overledger 2.2.0 release

DOWNLOAD THE UPDATE

Overledger 2.2.0 improves performance and data quality across APIs

17 February 2022 

Quant’s Overledger is the world’s first blockchain-agnostic API gateway. In Overledger 2.2.0, we enhanced the performance of the gateway and improved data consistency across our APIs. There are no new features added within this release.  

Quant has a steady product roadmap for Overledger to enable customers to create enterprise-grade smart contracts that function across blockchains, smart tokens for digital asset management and tools to analyse multi-DLT transactions.   

Developers should note that due to Overledger’s APIs changing in this release, any mDapps created in earlier versions of Overledger should be retested.  

Please see the Release Notes 2.2.0 for full details of the changes in version 2.2.0.

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
