Learn Cadence and DApp Development on the Flow Blockchain

What is Cadence?

Cadence is the smart contract language used on the Flow Blockchain. It's a resource-oriented language, inspired by Swift, Kotlin, and Rust.

Cadence features include:

• Use of resources

• Capability-based security

• Type safety and strong static type system

• Built-in pre and post-conditions for functions and transactions

A quick explanation of resources: Resources can only exist in one location at a time, cannot be copied and must be moved or explicitly destroyed.

So now that you have a little 🤏 understanding of Cadence, here are free resources - no pun intended - to start learning Cadence and DApp development #onFlow.
