This directory contains a set of constants presets used for testing, testnets, and mainnet.
A preset file contains all the constants known for its target. Later-fork constants can be ignored, e.g. ignore phase1 constants as a client that only supports phase 0 currently.
Each preset is a key-value mapping.
Key: an UPPER_SNAKE_CASE (a.k.a. "macro case") formatted string, name of the constant.
Value can be either:
- an unsigned integer number, can be up to 64 bits (incl.)
- a hexadecimal string, prefixed with
0x
Presets may contain comments to describe the values.
See mainnet.yaml for a complete example.
