LESA (Lesen asli, sijil asli) is a framework for converting assets into Ethereum-NFT. NFT (Token Standard): ERC-721 because assets such as licences or permits are unique to its owner. Smart Contract Development-ERC725: LESA smart contracts govern the creation, ownership, and transfer of NFTs. Metadata and Storage: Large storage for media such as images can be stored on a conventional system (specifically RDMS). User Interfaces and User Experience: LESA client currently employs a web-based but mobile-friendly and responsive layout - which is already familiar among web users. Security Considerations: LESA employs the best security practices to protect against potential vulnerabilities, such as secure coding practices, access control mechanisms, and protection against common attack vectors. LESA smart contract is derived from OpenZeppelin, a source library for smart contracts that have been audited.
Government Agency & Private Sector that require digital id, permit, licence or similar document that requires authentication.
Apart from the blockchain, LESA also employs the conventional centralised model. This technique makes the integration easier with the client's existing legacy system through REST-API endpoint(s). To generate verifiable NFT, LESA uses the Merkle tree algorithm and a private Ethereum blockchain network. With the algorithm and the decentralised model, the genuine LESA-NFT must be defined as having existence, ownership and record integrity.
The unique selling point (USP) for using open-source frameworks and libraries lies in the following aspects: Cost-Effectiveness: Open-source frameworks and libraries are typically available free of charge, making them a cost-effective choice for businesses and developers. By leveraging open-source solutions, companies can reduce expenses associated with software development, licensing fees, and proprietary technologies. Flexibility and Customization: Open-source frameworks and libraries offer a high level of flexibility and customization. Developers can modify the source code to meet specific requirements, add new features, and tailor the software to their needs. This freedom enables businesses to create unique and highly customised solutions that align with their goals. Collaboration and Community Support: Open-source projects often have vibrant and active communities of developers. These communities provide support, share knowledge, and contribute to the continuous improvement of the software. By using open-source frameworks and libraries, businesses can tap into a vast pool of expertise and benefit from the collective effort of the community. Transparency and Security: Open-source software is transparent, as the source code is openly available for review. This transparency enhances security by allowing developers to identify and fix vulnerabilities promptly. With many eyes on the code, potential issues can be quickly identified, leading to more secure software. Longevity and Reliability: Open-source frameworks and libraries are often developed and maintained by dedicated communities or organisations with a vested interest in their success. This ensures the longevity and reliability of the software, as updates, bug fixes, and improvements are consistently released. Businesses can rely on the continuous support and development of the open-source solutions they utilise. Avoiding Vendor Lock-In: Open-source frameworks and libraries provide an alternative to proprietary software that may lead to vendor lock-in. By using open-source solutions, businesses can avoid dependence on a single vendor and have more freedom to switch providers or customise the software as needed
