Universal BRC-20 Extension on Bitcoin

This document describes the Universal BRC-20 Extension on Bitcoin, based on an optimized UTXO + OP_RETURN approach, and revisits/improves the existing comprehensive guide.

Specification Details

  • Version: 1.1 (Allows extended ticker length)

Key Features

This Universal Extension preserves the original Ordinals shared-namespace principle while migrating all token metadata into compact OP_RETURN outputs. This approach:

  • Makes transactions significantly smaller and faster to propagate
  • Enhances censorship-resistance
  • Reduces on-chain footprint and fee costs
  • Enables native multi-recipient allocations
  • Prepares for the imminent lifting of OP_RETURN size limits
