Single Use Lock
Single Use Lock is a Lock Script that allows unlocking only when a specific OutPoint is consumed.
It is part of the ckb-proxy-locks.
How It Works
- Takes an outpoint (36 bytes) as an argument
args[0..36]: The specific OutPoint that must be consumed
- Passes validation only if the specific OutPoint appears in the transaction inputs. This ensures the Cell locked with this Script can only be unlocked once.
Use Cases
- One-time payments
- Voucher systems
- Single-use authorizations
Deployment
- Mainnet
