In the Solana ecosystem, smart contracts are known as on-chain “programs”. These programs are compiled with LLVM to an Executable and Linkable Format (ELF). It also utilizes a variation of the Berkeley Packet Filter (BPF) for the program instruction set. Storage on Solana requires low level management. For anyone who worked in embedded systems this will feel like a breeze of familiar air.

This post is a follow up on my previous notes on the Solana development environment setup and touches on building and deploying Solana programs with Rust, the eBPF instruction set and what I learned so far started developing on Solana.
