Exploding keys are public keys that commit to a set of outputs. If a key is spent to those outputs, no signature or witness is required. The concept offers similar functionality to OP_CTV but with a more efficient implementation, saving bytes in transaction size. The idea leverages Taproot-like public key commitments as described in BIP-341 and involves replacing witness data with public key commitments, providing a new primitive for efficient Bitcoin covenants. Here's how it works:
