Announcing Overledger 2.0 Full Release


Following on from the April release, today we launch the Full Release of Overledger 2.0, providing interoperability to Ethereum, XRP and Bitcoin Mainnets.  

This update delivers the significant functionalities that were shared in the Preview Release for use on Mainnets, alongside the exciting new features that have been developed:

  • New API – The new Overledger API has been transformed into “One API for everything”, bridging the global ecosystems of DLTs and APIs
  • Standardised – Based on ISO TC/307 providing simple and standard interface to access all supported DLTs and Blockchains 
  • Secure and Scalable – Implemented OAuth federated authentication standards, enabling single sign-on for enterprise customers and implemented scalability and resilience updates for cloud infrastructure 

Our new approach for Overledger works as a “Universal Translator” for enterprise and community developers and users benefiting from using a simple and standard interface to access all supported DLTs.

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
