Hashed Time-Lock Contract Efficiency

Hashed Time-Lock Contract Efficiency relates to the computational and temporal cost of using smart contract scripts that require cryptographic hashes and time-based conditions to secure atomic swaps. While these contracts provide security by ensuring that funds can only be claimed if a secret is revealed or a time limit expires, they are resource-intensive.

The efficiency is measured by the number of on-chain operations required to initiate, participate, and complete the swap. High-efficiency implementations minimize the gas cost and block space used, allowing for faster settlement.

However, the requirement for time-locks introduces an inherent delay, as parties must wait for the contract to expire if a trade fails. Improving efficiency involves streamlining the script logic and integrating off-chain state channels to reduce the number of direct interactions with the base blockchain.
