Programs in Solana

In Solana , all executable smart contracts are know as programs. Smart contracts / Programs are the onchian accounts which contains executable code , logic and functions stored in the organized way. This is knows as Instructions. We have some major key points of Accounts in Solana ecosystem, here are they :

1. On-Chain activity : They contain executable code organized into distinct functions called instructions.
2. Stateless nature : They do not store data themselves but can create new accounts to manage program state.
3. Upgradeable : Programs can be updated by an authority. Once the upgrade authority is set to null, the program becomes immutable.
4. Verifiable builds : Users can verify that on-chain programs match publicly available source code.

How to write Programs on Solana

Solana programs are mainly written in the Rust programming language. There are two common approaches:

1. Anchor Framework (opens in a new tab) : A framework that simplifies Solana program development. It uses Rust macros to reduce boilerplate code. It's ideal for beginners.

2. Rust (opens in a new tab): Writing Solana programs directly in Rust without using frameworks. Offers more flexibility but is more complex.
