Developers can write and deploy their own programs to the Solana blockchain. While developing these "on-chain" programs can seem cumbersome, the entire process can be broadly summarized into a few key steps.

## Solana Development Lifecycle

1. Setup your development environment
2. Write your program
3. Compile the program
4. Generate the program's public address
5. Deploy the program

### 1. Setup your development environment

The most robust way of getting started with Solana development, is [installing the Solana CLI](./../../cli/install-solana-cli-tools.md) tools on your local computer. This will allow you to have the most powerful development environment.

Some developers may also opt for using [Solana Playground](https://beta.solpg.io/), a browser based IDE. It will let you write, build, and deploy on-chain programs. All from your browser. No installation needed.

### 2. Write your program

Writing Solana programs is most commonly done so using the Rust language. These Rust programs are effectively the same as creating a traditional [Rust library](https://doc.rust-lang.org/rust-by-example/crates/lib.html).

### 3. Compile the program

Once the program is written, it must be complied down to [Berkley Packet Filter](./faq.md#berkeley-packet-filter-bpf) byte-code that will then be deployed to the blockchain.

### 4. Generate the program's public address

Using the [Solana CLI](./../../cli/install-solana-cli-tools.md), the developer will generate a new unique [Keypair](./../../terminology.md#keypair) for the new program. The public address (aka [Pubkey](./../../terminology.md#public-key-pubkey)) from this Keypair will be used on-chain as the program's public address (aka [`programId`](./../../terminology.md#program-id)).

### 5. Deploying the program

Then again using the CLI, the compiled program can be deployed to the selected blockchain cluster by creating many transactions containing the program's byte-code. Due to the transaction memory size limitations, each transaction effectively sends small chunks of the program to the blockchain in a rapid-fire manner.

Once the entire program has been sent to the blockchain, a final transaction is sent to write all of the buffered byte-code to the program's data account. This either mark the new program as [`executable`](./../programming-model/accounts.md#executable), or complete the process to upgrade an existing program (if it already existed).

## Support languages

Solana programs are typically written in the [Rust language](./developing-rust.md), but [C/C++](./developing-c.md) are also supported.

There are also various community driven efforts to enable writing on-chain programs using other languages, including:

- Python via [Seahorse](https://seahorse-lang.org/) (that acts as a wrapper the Rust based Anchor framework)

## Example programs

The [Hello world example](examples.md#helloworld) is a good starting place to see how a program is written, built, deployed, and interacted with on-chain.

You can also explore the [Program Examples](./examples.md) for other examples of on-chain programs.

## Limitations

As you dive deeper into program development, it is important to understand some of the important limitations associated with on-chain programs.
