|
An [app](terminology.md#app) interacts with a Solana cluster by sending it
|
|
[transactions](transactions.md) with one or more
|
|
[instructions](transactions.md#instructions). The Solana [runtime](runtime.md)
|
|
passes those instructions to [programs](terminology.md#program) deployed by app
|
|
developers beforehand. An instruction might, for example, tell a program to
|
|
transfer [lamports](terminology.md#lamports) from one [account](accounts.md) to
|
|
another or create an interactive contract that governs how lamports are
|
|
transferred. Instructions are executed sequentially and atomically for each
|
|
transaction. If any instruction is invalid, all account changes in the
|
|
transaction are discarded.
|

|
To start developing immediately you can build, deploy, and run one of the
|
|
[examples](developing/deployed-programs/examples.md). |
