Quant Network today announced The Overledger Network: “The network of networks for a Hyper-connected world“.

Overledger Network powers universal decentralisation as the market infrastructure for digital assets.

Quant Network has already solved interoperability through Overledger, which is an operating system (OS) that enables any legacy network and current and future blockchains and distributed ledger technologies to interconnect at scale. Today we are proud to share our plans for The Overledger Network.

The Overledger Network is in essence a network of networks, which allows enterprise and communities stakeholders to access and host their own Overledger gateways and participate in a growing hyper-connected decentralised ecosystem.

Enterprise will be able to host their own secure dedicated gateways, opening up the many benefits that may arise from hyper-decentralisation which come from the ability to connect their networks securely to distributed systems, permissioned networks, permissionless networks, ecosystems, consortia and other distributed technologies.

Solving the challenges of companies operating in silos, the Overledger network provides interoperability to connect and prosper. The resulting benefits facilitate enterprise access to new markets and new users across all the different blockchains without compromising their corporate security policies and regulation.

The benefits also extend beyond enterprise to the thriving blockchain community. By hosting an Overledger Network Gateway, the community members will be helping to build the next generation hyper-decentralised applications and ecosystem.

In return for participating in the Overledger Network ecosystem, community members will be able to earn QNT, the extent of which can vary depending on the gateway tiers and volume.

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 

Native Transactions 

OVL 2.0 Developer portal 2.0
