Parameters:

where - the file channel where the nonce must be dumped

metadataSize - the size of the metadata of the plot file, that precedes the nonces

offset - the progressive number of the nonce inside the file; for instance, if the file will contains nonces from progressive 100 to progressive 150, then they are placed at offsets from 0 to 50 inside the file, respectively

length - the total number of nonces that will be contained in the file

Throws:

IOException - if the nonce could not be dumped into the file
