This subnet requires commit-reveal for weights , but you called set_weights directly.

Encountered by: validatorsdevelopers

Why This Error Exists

Commit-reveal prevents front-running and weight copying. Without it, validators could watch the mempool and copy others' weights before they're confirmed. With commit-reveal, you first submit a hash (commitment), then later reveal the actual weights. This ensures everyone commits before anyone can see others' choices.

Deep Dive

CommitRevealWeightsEnabled is a per-subnet boolean. When true, direct set_weights calls are rejected. Instead: 1) Call commit_weights with hash(weights, salt), 2) Wait for commit period to end (WeightCommitRevealInterval blocks), 3) Call reveal_weights with actual weights and salt. The hash must match for reveal to succeed.

Debugging Example

You call set_weights(netuid=18, uids=[...], weights=[...]). Error: CommitRevealEnabled. Query CommitRevealWeightsEnabled(18) - returns true. This subnet uses commit-reveal. Solution: Generate a salt, compute hash = keccak256(weights || salt), call commit_weights(netuid=18, hash), wait for reveal period, then call reveal_weights(netuid=18, weights, salt).

Prevention Tips

  • Check CommitRevealWeightsEnabled(netuid) before setting weights
  • Implement commit-reveal logic in your validator software
  • Store your salt securely - you need it for the reveal phase

What This Means

This subnet requires commit-reveal for weights, but you called set_weights directly.

Common Causes

  • Subnet has commit-reveal enabled
  • Must use commit_weights then reveal_weights

How to Fix

  • Use commit_weights to commit a hash of your weights
  • Then use reveal_weights after the commit period
  • Check CommitRevealWeightsEnabled for subnet setting
