Overledger 2.2.4 introduces support for Polkadot Westend Testnet

DOWNLOAD THE UPDATE

Overledger now supports Polkadot Westend TestNet (Relay Chain only) through new standardised APIs.

14 April 2022

Polkadot (DOT) is a blockchain network that connects to multiple Substrate-based blockchains; it also handles their security and transactions and provides bridges to other networks like Ethereum and Bitcoin.  

Martin Hargreaves, Quant’s Chief Product Officer, says, “with our latest Polkadot release, we are building deeper interconnectivity into Overledger. Our public Software as a Service (SaaS) already connects to chains like Ethereum, Bitcoin, XRP Ledger and Polygon. Additionally, we also have connectors to permissioned blockchains like Hyperledger Fabric and Corda. Quant's aim is to create a highly secure, enterprise-grade gateway and token-issuance platform that works seamlessly with the most commonly used blockchains.”  

Overledger API functions can be performed on Polkadot Westend TestNet, including creating a DOT transaction, searching a transaction or a block and more. Note: Overledger’s APIs for Polkadot do not support smart contract functionality as this is not supported by the underlying relay chain.

Martin adds, “essentially, with the new Polkadot release, we can now connect to blockchains whose purpose is to connect to other blockchains. Effectively, Overledger is a higher-level interoperability layer.”

Support for Polkadot MainNet (Relay Chain only) will be available in the next release.

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
