Blockchain

With no less than 14 consensus algorithms, 20+ blockchain infrastructure vendors, multiple protocols – it is an ardent task to choose which technology component is suitable for a specific customer use case. Happiest Minds can assist in making this choice with its experience in working with multiple algorithms, infrastructure and platforms, use cases and the overall ecosystem. Happiest Minds brings to the table a strong Software Defined Infrastructure focus, which enables the design of a robust, scalable and high-performance blockchain infrastructure. Governance & compliance is a self-driven task for enterprises today; our risk & compliance teams can help with these challenges with our readily deployable framework.

For implementing a reliable and scalable blockchain solution – there are a few attributes that need to be considered for engineering the underlying hardware and software platform like- Secure processing, high speed transactions, interoperability with other systems, and reliability and assurance. Happiest Minds’ expertise in product and platform engineering can be leveraged to create platforms, components and applications that address the above challenge by providing:

• System design including FPGA development and verification for high speed and programmable cryptographic transactions.
• High Speed Solid State/NVMe Storage and Networking systems design and development.
• Cloud development – Azure Work Bench, Hyperledger and other cloud development services for private clouds, AWS, Azure and Google cloud.
• Big Data Platform engineering and Analytics.
• Monitoring and Assurance.

dAPPS or distributed applications are the interfaces that users interact with to harness the power or benefits of blockchain and smart contracts. Happiest Minds has a strong Cloud and Mobile engineering practice with extensive experience in building domain specific applications for industries like Industrial, BFSI, Supply Chain, Retail and Telecom. Happiest Minds can be your partner for building successful dAPPs which can scale by ensuring the following:

• Leverage the strong UX and Business Analyst practice to ideate and create work flows, prototypes, wireframes.
• Develop UI using modern web technology stacks such as Angular, React/Node.
• Application development on mobile platforms such as Android & iOS.
• Integrate the app with smart contracts and blockchain platforms.
• Scalable design using Microservices.
• Model based continuous testing, test automation and DevOps.

Simply explained, smart contracts are digital versions of regular contracts. Programmatically, they are standalone scripts that execute automatically when certain conditions are met. Coupled with the underlying immutable and decentralized blockchain network, smart contracts can enable efficient operations by minimizing—or in some cases eliminating—dependence on humans and third-party agents, while also opening the door to innovative business models. Happiest Minds has core expertise in building applications with domain knowledge in many industry verticals and thus can be a partner of choice for engineering smart contracts.

• Development of Smart Contracts using Java Script, Python, C++ and domain specific smart contract languages like GO and SOLIDITY on platforms such as Ethereum, Hyperledger & Azure Work Bench
• Testing and Test Automation of Smart Contracts using Model Based Testing approach and framework
• Audits & Analytics
• Business Process Integration

While blockchain ensures transparency and openness, it can also expose systems of record to serious vulnerabilities. Some of the key security risks associated with blockchain include crypto key tampering, misused timestamps, permission escalation, genesis block tampering, inappropriate consensus mechanisms, DoS attacks, and man-in-the-middle attacks. Additionally, as the largest possible public ledger, blockchain poses significant risks to data privacy and the right to be forgotten. Happiest Minds has a thriving cybersecurity practice, and we have developed secure systems that provide services to negate or minimize these risks while deploying and managing blockchain. Our blockchain security services include:

• Secure Access- Secure and private access design, distributed ledgers, consensus protocols, smart contracts and cryptography. Data & communication encryption, key management, distributed identity establishment.
• Data Privacy- Segregate & encrypt PII data that provides data privacy & security. Strong Key management system, forgetting the keys will ensure the “right to be forgotten."
• Self-Sovereign Identity- Identity encryption for privacy and mapped for legal assurance. Anonymizing layers of distinct, purpose-specific identity relationships with different counter-parties. Identity through ownership of private keys.
• Application Security- Secure architecture, API Security, Secure code/Configuration review tools. Assessment of services hosting the platform, SDKs, and APIs used by the applications to communicate with the Blockchain ecosystem. Incorporating the best security practices in coding. Threat Prevention & Device Security Advanced threat prevention tools – cyber & risk analytics, RPA driven IM & resolution. Endpoint security, ETDR, Port security, device authentication, secure communication, configuration management, continuous monitoring and secure patch management.
• Third Party Security- Third party platform security review and remediation to prevent ‘51% attacks’. Vulnerability management of the Blockchain nodes working in unison and the network.

The dAPPS, which are use case specific, interact with the underlying infrastructure through a middleware that provides essential services. Happiest Minds can assist in building these services, which may include identity service, policy management, consensus manager, smart contract services, and event streaming services. Happiest Minds has strong Big Data and Analytics engineering capabilities which can be leveraged to build plugins to the Blockchain infrastructure and derive intelligence for use cases such as:

• Failure Prevention & Self-Healing
• Business Intelligence
• Anomaly Detection
