Overledger 2.0 Preview Release by Quant

Announcing Overledger 2.0 (Preview Release)

DOWNLOAD THE UPDATE

Quant Overledger Preview Release 2.0 is the first release on our new architecture and the base for an exciting roadmap of functionality in the gateway  and preparing for Overledger Network.

The new Overledger API has been transformed into “One API for everything”, bridging the global ecosystems of DLTs and APIs.

Built upon international standards from ISO TC/307, and our move to OAuth federated authentication standards, Overledger will connect even more enterprise and user communities to the Overledger Network via seamless single sign-on.

This latest release showcases Overledger 2.0’s updated API so that requests and responses are standardised and consistent regardless of the DLT developers and users interact with and the start to move away from SDK dependencies to an API-first scalable platform.  

This new approach for Overledger works as a “Universal Translator” for enterprise developers, community developers and users benefiting from using a simple and standard interface to access all supported DLTs and Blockchains. We’re rolling out Preview Release 2.0 connected to Testnet blockchains first, then shortly to Mainnet blockchains in the subsequent releases. Legacy Overledger 1.5 API and SDK with both Testnet and Mainnet connectivity will be maintained until users fully transition to 2.0 by the end of 2021.

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
