Quant introduces Overledger 2.0.1 with four new API extensions

DOWNLOAD THE UPDATE

This next release for the Overledger 2.0 platform expands the functionality available to multi-DLT applications.  

Multi-DLT applications (mDApps) are faster and simpler to create with the Overledger 2.0 API and now include these additional extensions: 

  • Native DLT Transactions allow advanced DLT developers to send native transactions through the Overledger UI for total flexibility.
  • Monitor events on addresses and smart contracts across different DLTs using our standardised API.  
  • Subscriptions allow developers to get real time updates on the monitors they set up to a call-back URL, and to pause/restart their subscriptions. 
  • Application Transaction Query allow developers to retrieve a list of transactions their application made using Overledger and zoom in on a particular transaction to obtain more detailed information.

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
