//! Zagros Testnet: Reduce validator count from 21 to 4 via sudo
|
|
//!
|
|
//! Sends two sudo calls:
|
|
//! 1. sudo(staking.setValidatorCount(4))
|
|
//! 2. sudo(staking.forceNewEra())
|
|
//!
|
|
//! Run with:
|
|
//! SUDO_MNEMONIC="******" \
|
|
//! RPC_URL="ws://217.77.6.126:9948" \
|
|
//! cargo run --release --example zagros_reduce_validators
