State
State describes information available to programs and applications. It changes through authorized instructions.
FOUNDATIONS
Architecture in plain language
A blockchain is easier to understand when its responsibilities are separated. Accounts hold state, programs describe behavior, validators participate in agreement, and clients provide the software through which the network is observed.

Execution
Programs define logic, while transactions carry instructions that request a change.
Agreement
Validators coordinate on the order and validity of updates through the network protocol.
Experience
Wallets, explorers, and applications translate technical activity into human-readable interactions.
