Constant zebra_consensus::MAX_BLOCK_SIGOPS

pub const MAX_BLOCK_SIGOPS: u64 = 20_000;

The maximum allowed number of legacy signature check operations in a block.

This consensus rule is not documented, so Zebra follows the zcashd implementation. We re-use some zcashd C++ script code via zebra-script and zcash_script.
