Typedef Documentation

CScriptBase

typedef prevector<28, unsigned char> CScriptBase

We use a prevector for the script to reduce the considerable memory overhead of vectors in cases where they normally contain a small number of small elements.

Tests in October 2015 showed use of this reduced dbcache memory usage by 23% and made an initial sync 13% faster.

These are needed because script.h and script.cpp do not have access to asset.h and asset.cpp functions.

This is because the make file compiles them at different times. This is becauses script files are compiled with other consensus files, and asset files are compiled with core files

These are needed because script.h and script.cpp do not have access to asset.h and asset.cpp functions.

This is because the make file compiles them at different times. The script files are compiled with other consensus files, and asset files are compiled with core files. Used to check if an asset script contains zero assets. Is so, it should be unspendable
