Validating Your Next Blockchain Idea

Before you start coding any blockchain project, you must validate it. Not every application needs a distributed ledger.

Ask yourself these questions to validate your blockchain idea:

1. Decentralization: Does it need to remove a middleman?
2. Transparency: Does the history need to be public?
3. Immutability: Should the records be permanent and unchangeable?

If your idea fits these criteria, you are ready to build. Whether you choose simple blockchain projects to learn the ropes or tackle advanced blockchain project ideas to innovate, the key is to start coding today.
