Challenge
In Blockchain ecosystems, smart contacts are central to the implementation of business rules and legal conditions; a vulnerable smart contract could lead to an insecure system due to inherent immutability. Thus, there is a high risk of loss of data, disputes, and reputational damage.
Solution
Evolution of standards like ERC (Ethereum Request for Comments) brings consistency and a high level of compliance in testing for fungible and non-fungible smart contracts. Additionally, robust functional testing rules out vulnerability as well as the anomaly in functional logic of smart contracts and makes the ecosystem more secure. Magic QA team is constantly enriching its testing by aligning to various ERC standards such as ERC-20, ERC223, ERC721, and applying learning from its experience.
Challenge
When a new block is created, partial data due to transaction failure could lead to corrupt state of the block, leading to transaction failure and eventually the chain.
Solution
Verifying data atomicity at block level is the best way to prevent such issues. Magic QA team has built a standardized test suite that contains test cases and scenarios to test new blocks and its atomicity. These can be reused and customized to adapt to the new blockchain core implementations.
Challenge
Blockchain is very secure and impossible to decrypt. This is the inherent assumption. Smart contracts are used to implement secure permissions in blockchain network. Vulnerable smart contracts could lead to unauthorized sensitive data leaked and synced with other nodes in network and eventually lead to external entity accessing and decrypting public or private transactions within blockchain network.
Solution
Standardized Smart contract implementation such as ERC standards and component’s(nodes) domain driven permission to share data in public and private blockchain network helps to prevent unauthorized access to transaction data, permission and consensus manipulation for business gain.
Magic QA team’s experience in Smart contracts and ERC standards would help in creating relevant scenarios to test vulnerability and security in blockchain networks.
Challenge
Operational stability of network is very critical in blockchain transactions. High transaction volatility and slow network scalability might lead to network failure.
Solution
Magic QA identified Scalability Testing and Volatility Testing as essential testing scenarios to ensure network robustness. Automated programs progressively add and removes nodes to network & monitors their current state, network state and nodes alignment with hosted network
