Native packages are integral parts of Solana’s core blockchain mannequin.
Low-level languages resembling C/C++ and Rust assist in creating native packages. The native packages are optimized to attain higher safety and efficiency, and any program or consumer can name native packages. However, customers can not straight name or entry a kernel-level program in your working system.
Updating the native packages may occur solely because of the cluster upgrades or core blockchain upgrades. The upgrades may give attention to enhancing efficiency, including new options, and fixing bugs. Each Solana program library instance may make it easier to perceive how native packages may assist in securing the validator. Among the notable variants of native packages on Solana embody system packages, stake packages, and Berkeley Packet Filter or BPF packages.
System Applications
The first performance of system packages revolves round creation of recent accounts, project of account possession, and transferring SOL tokens between accounts. As well as, system packages are helpful instruments for performing many different account administration duties within the Solana ecosystem.
Stake Program
The stake packages in Solana ecosystem may also help in administration of the method for staking SOL tokens on Solana blockchain.
Berkeley Packet Filter
The Berkeley Packet Filter or BPF packages are helpful for managing the method of deploying and implementing upgrades and the on-chain execution of packages.
