1.2. jar1 Settings🔗

The jar1 variant uses these configuration choices:

• Memory model: capability-based (DATA caps manage physical pages with exclusive mapping)

• Gas model: basicBlockSinglePass (O(n) pipeline simulation per basic block)

• Capability model: v2 (multi-VM kernel, capability-based)

• Blob encoding: u32 LE count prefixes (not JAM compact natural encoding)

• Variable validators: enabled (GP#514 — active core count scales with validator count)

• Economic model: QuotaEcon (coinless, quota-based storage limits)

• Transfer payload: QuotaTransfer (pure message-passing, no token amount)

• Codec: Codec.Jar1 namespace (u32 LE field encoding throughout)
