# generate-validator-keys.sh — Generate validator key pairs for the workload harness.
|
|
#
|
|
# Uses a temporary standalone xrpld instance to call `validation_create` RPC
|
|
# for each node. Outputs a JSON file mapping node index to seed + public key.
|
|
#
|
|
# Usage:
|
|
# ./generate-validator-keys.sh <xrpld_binary> <num_nodes> <output_dir>
|
|
#
|
|
# Output:
|
|
# <output_dir>/validator-keys.json — JSON array of {index, seed, public_key}
|
|
# <output_dir>/validators.txt — [validators] section for xrpld.cfg
