Runtime IDs

Identifiers for runtimes are represented by the common.Namespace type.

The first 64 bits are reserved for specifying flags expressing various properties of the runtime, and the last 192 bits are used as the runtime identifier.

Currently the following flags are defined (bit positions assume the flags vector is interpreted as an unsigned 64 bit big endian integer):

  • Bit 63: The runtime is a test runtime and not for production networks.
  • Bit 62: The runtime is a key manager runtime.
  • Bits 61-0: Reserved for future expansion and MUST be set to 0.

Note: Unless the registry consensus parameter DebugAllowTestRuntimes is set, attempts to register a test runtime will be rejected.
