Gather Avalanche Subnets stats using Ash CLI

ash-avalanche-stats.sh

#!/bin/bash

export AVALANCHE_NETWORK="${AVALANCHE_NETWORK:-mainnet-ankr}"

echo "Avalanche Network: $AVALANCHE_NETWORK"

# Get the list of Subnets with at least one blockchain (exclude the Primary Network)
SUBNETS_W_CHAINS=$(
  ash avalanche subnet list --json |
    jq -r '.[] | 
       select(.id != "11111111111111111111111111111111LpoYY") |
       select((.blockchains | length) > 0) | .id'
)

echo "Subnets with blockchains: $(echo "$SUBNETS_W_CHAINS" | wc -l)"

# Get the list of Subnets with at least one validator
SUBNETS_W_VALIDATORS=$(while read -r s; do
  ash avalanche subnet info "$s" --json |
    jq "{\"id\": \"$s\", \"validators_count\": (.validators | length), \"type\": .subnetType}"

# Get the number of permissioned Subnets
PERMISSIONED_SUBNETS=$(echo "$SUBNETS_W_VALIDATORS" | jq -s '.[] | select(.type == "Permissioned")' | jq -s 'length')

echo "Subnets with validators:  $(echo "$SUBNETS_W_VALIDATORS" | wc -l)"
echo "Permissioned / elastic:   $PERMISSIONED_SUBNETS / $(($(echo "$SUBNETS_W_VALIDATORS" | wc -l) - $PERMISSIONED_SUBNETS))"
echo "Total Subnet validators: $(echo "$SUBNETS_W_VALIDATORS" | jq -s '. | map(.validators_count) | add')"
echo "Avg number of validators: $(echo "$SUBNETS_W_VALIDATORS" | jq -s '. | map(.validators_count) | (add / length)')"

Requirements

• jq
• Ash CLI

Picking the network

You can export AVALANCHE_NETWORK to choose another network (e.g. fuji). It has to be in your Ash config (see Custom configuration).

export AVALANCHE_NETWORK=fuji

Sample output

Avalanche Network: mainnet
Subnets with blockchains: 38
Subnets with validators:  24
Permissioned / elastic:   24 / 0
Total Subnet validators: 151
Avg number of validators: 6.291666666666667
