Function Documentation

◆ GetMaxBlockSigChecksCount()

uint64_t GetMaxBlockSigChecksCount ( uint64_t  maxBlockSize)
inline

Compute the maximum number of sigchecks that can be contained in a block given the MAXIMUM block size as parameter.

The maximum sigchecks scale linearly with the maximum block size and do not depend on the actual block size. The returned value is rounded down (there are no fractional sigchecks so the fractional part is meaningless).
