BLISK: Boolean circuit Logic Integrated into the Single Key

The discussion is centered around the implementation of Hashed Timelock Contracts (HTLCs) using BLISK, which appears straightforward at first glance. An HTLC structure typically consists of conditions allowing transactions to be executed if either a secret preimage is revealed (A & preimage) or a certain block height is reached (B & blockheight). The approach suggested involves compiling the individual policies for A and B into single public key points. This compilation process effectively simplifies the execution of transactions by utilizing tapleaves for each condition, specifically (policy-A & preimage) and (policy-B & blockheight).

It's noted that the use of SCRIPT is essential for hashlocks to function properly within this framework. Furthermore, an optimization technique is proposed, involving the addition of a policy(A & B) keypath spend. This method aims to streamline the transaction process further, potentially enhancing the efficiency and security of executing transactions under specific conditions set forth by the HTLC mechanism. The conversation implies a technical depth in understanding blockchain technology, particularly in how transactions can be securely and conditionally executed using advanced cryptographic techniques.
