pub const GETDATA_MAX_BLOCK_COUNT: usize = 16;
Expand description

The maximum number of blocks the Inbound service will queue in response to a block request, before ignoring any additional block IDs in that request.

This is the same as zcashd’s request limit:

(Zebra’s request limit is one block in transit per peer, because it fans out block requests to many peers instead of just a few peers.)
