Library designed to support the creation of interfaces for reading, parsing and writing energy industry related data to and from the blockchain.
Further development and contribution enhancing generalization of the tool is much welcome, please contribute with issues and pull requests. :)
Simply install it as a dependency with pip3 install ew-link-bond,
- Raw transactions signing
- Extension and reusability through OOP
- Further support of Energy Assets
- Enforce TLS/SSL over http
- Artik710/710s support with:
- Offloaded cryptography to hardware acceletors
- Storage and access of the configuration file on secure enclave
- Private key generation and siganture on secure enclave (Artik710s only)
- Energyweb's Asset Registry
- Energyweb's Certificate of Origin v2.0
- Your project here - We are open for suggestions!
The library is organized into abstract, input and output. Abstract defines all classes and interfaces to be inherited and implemented by input and output classes. As the names imply the software consists of loading and reading one or many input modules and write formatted data to output modules.
The core library comes with an object-oriented structure to standardize and support the extension of the input and output modules, thus extending the system functionalities and ability to communicate with other Energy Assets.
Object to abstract data persistence, allowing connection to databases and disk storage using the same interfaces.
Descriptor loader to speed up the development of a bond-based app.
This library can be used to load a json file that describes the modules to load for production and comsumption of energy, as well as to which blockchain clients and persistence modules to store the data collected.
Designed with reflection in mind, the configuration file needs to have a list of consumption, and production. Consumers require the keywords energy-meter, and smart-contract. Producers require the keywords energy-meter, and carbon-emission, smart-contract.
These keywords are objects describing python-like module path, case-sensitive class_name and a dictionary of class_parameters that are required in the chosen class constructor.
