How do I design a Blockchain app?
- What capabilities should the solution provide to users?
- Will the proposed solution mitigate or eliminate user pain points?
- What actions should the solution restrict?
- Does the solution require readiness for high traffic from day one?
- Is Blockchain the appropriate technology to enhance your solution?
- How does Blockchain improve the end-user experience?
- Has your organization previously developed custom software solutions?
- What level of support is required?
- What is the size of the developer community?
- Does your future vision align with the project or platform’s roadmap?
- Does the platform aim to innovate or focus on efficiency and cost reduction?
- Should the solution utilize a public or private Blockchain?
- Should the solution be open or closed source?
- Plan for smart contract updates and changes
- Hybrid solutions
- Monetary exchanges
How do I develop a Blockchain app?
- Agile approach prior to release
- Establish guiding principles early
- Software versus firmware considerations
- Focus on announcements rather than transactions
- Use classes instead of contracts where applicable
- Link contracts to share functions
- Utilize calling contracts to maintain consistent contract addresses
- Hyperledger versus Ethereum comparisons
- Consider the number of users and transactions per user
- Evaluate the need for blockless solutions
