the same pragmas are available as for ordinary variables. As let statements are immutable after creation they need to de�ne a value when they are declared. The only exception to this is if the {.importc context at instantiation are considered: In the example, the generic `==` for tuples (system.html#%3D%3D%2CT%2CT_2) (as de�ned in the system module) uses the == operators of the tuple's components. However lib/pure/strutils.toUpperAscii("abc") import lib/pure/strutils as strutils import "gfx/3d/somemodule" # in quotes because '3d' is not a valid Nim identifier From import statement After the from keyword, a

ordering service, and the channel configuration transaction file is broadcast to the orderer at Channel creation time. The anchor peer transactions, as the name might suggest, specify each Org’s Anchor Peer on the peer’s MSP to instantiate chaincode. Package signing A chaincode package that was signed at creation can be handed over to other owners for inspection and signing. The workflow supports out-of-band Signed- CDS and must also be a writer on the channel, which is configured as part of the channel creation. This is important for the security of the channel to prevent rogue entities from deploying chaincodes

Because of this change, R1 was able to define the consortia X1 and X2, and create the ordering service, and the channel configuration transaction file is broadcast to the orderer at Channel creation time.
