 Registering shard 2 in the Status shard cluster (with shard cluster index 16, see [WAKU2-RELAY-STATIC-SHARD-ALLOC](https://github.com/waku-org/specs/blob/waku-RFC/informational/relay-static-shard-alloc.md),
 the register query would look like
 
 ```
-REGISTER{0x727300100002, {QmA, AddrA}}

 Participation in further shards is registered with further queries; one register query per shard.

 A discovery query for nodes that are part of this shard would look like
