DL ECOSYSTEM MULTITENANCY SAAS PLATFORM v5.0.0

September 29^th, 2022 Version 5.0.0

In this release the DL Ecosystem platform now supports multitenancy, meaning a single instance can serve multiple clients. This release has significantly improved the tenant onboarding process, and now an admin is associated with each tenant.

The DL Ecosystem application has well-defined and segregated role-based access for Platform Admin and Tenant Admin. Additionally, new features are implemented to enhance the application further.

DL Ecosystem is a blockchain-based platform that enables peer-to-peer banking. The platform supports a ‘Bank-in-a-Box’ system which allows buyers and sellers to transact directly with one another, removing the need for a middleman and significantly reducing the transaction costs. Users can make a point-to-point transfer of any value privately and securely. DL Ecosystem seamlessly facilitates the movement of value between two people or enterprises by supporting financial transactions like credits, debits, and the transfer of money. The application provides support for multitenancy and can operate with fiat currencies.

ASIK Ecosystem Updates

Fabric Enhancements:
- Multiple Fabric Orderers and Peers support.
Configurations Enhancements:
- Introduction of dynamic configurations.
- Creation of tenant now have an extra configuration to support private ES Cluster for Synching.

DL Libraries Enhancements:
- Support of AWS MSK via DLT-Kafka Module.
- Support of dynamic consumer group ids in DLT-Kafka.
- Cache worker support for any table in the Database provided.

ASIK Rules Engine Updates

ASIK Rules Engine is a blockchain based “Business Rules Engine” service that can be used by any application, service, or tool to configure their runtime behavior as per their business requirements. It is achieved by providing the client with an interface to do CRUD operations on Rules.

In ASIK Rules Engine, Rules are JSON objects that contain a set of conditions which produces a Boolean (true/false) result when executed against any input data. A client can define their own Rules in the system matching their business requirements and can use the Rule Execution feature to verify any untrusted data. This untrusted data is usually a public API request and is referred to as a “transaction” within ASIK Rules Engine.
