Approaches to Blockchain

Our world-class team, of course, suggests which Blockchain approach would best fit your business. But, we let you have the last word before we get things rolling for you. Here are the Blockchain approaches we think can transform your business.

Public

Permission-less and non-restrictive, public blockchains work best when maintaining large user bases where any member of the shared network can verify records, do proof-of-work, or engage in mining.

Private

When confidentiality is vital, private blockchains are the best. Private blockchains allow access to data to only those participants who matter, letting data out on a need-to-know basis.

Hybrid

Hybrid blockchains are a blend of both private and public blockchains. In this model, users can share data with the public and keep things confidential if needed, making the ecosystem super flexible.

Our Blockchain Development Process

Discovery Stage

We look at your project requirements at this stage. We try to get a sense of what blockchain solutions you need. Each blockchain network (public, private, and hybrid) has distinct pluses and minuses. So, we decide which one will best drive your goals. In short, we gather all requirements at this stage and form an initial workflow based on that.

Product Feasibility Study

Next, we do a theoretical build-up of your blockchain app or website, outlining the architecture, frameworks, consensus mechanism, tech stacks, mockups, designs, and feasibility. Once our stakeholders approve the prototype and our Proof-of-Concept (POC), we proceed with the development work.

Product Development

At this point, we focus on the blockchain platforms, programming languages, UI/UX, databases, APIs, and the middleware that connects the external systems with the blockchain. Our developers test and release an alpha version to spot issues. Once we fix all gaps and find the product doing well in the market, we add more complex features down the road.

Support and Maintenance

Our job doesn’t end with just the product launch. We offer post-launch support too. We closely monitor the transactions executed in blockchain and keep a regular watch to remove bugs/glitches (if any). We even handle feature upgrades from time to time to ensure your product is always up to date and functions flawlessly throughout its lifetime.
