Architecture
Shared security.
Sharded execution.
A masterchain coordinates configuration and validators. The Native workchain hosts TVM accounts, and shardchains partition their state and execution.
One network. Multiple execution partitions.
The standard genesis profile enables the masterchain and Native workchain 0. The codebase supports shard split and merge operations; the diagram shows the architecture, not a live shard count.

Simplex consensus.
QUIC transport.
Validators authenticate proposals and votes, form weighted quorum certificates, and advance notarization and finalization. The canonical profile selects Simplex v2 over QUIC.
Execution is message-driven.
TVM executes contract code over cells with deterministic gas accounting. A transaction has distinct compute, action, and bounce behavior. Cross-contract work spans messages and must handle replies and failures explicitly.
