Latest Patents

Hyungjoon Koo holds a patent for a "Watermarking method for smart contract." This method involves compiling the source code of a smart contract to create both contract creation bytecode and runtime bytecode. The process includes generating a control flow graph that consists of multiple byte regions based on the runtime bytecode. By setting opcode groups and extracting a watermarkable byte region, he can embed a watermark without incurring additional executable code or gas fees in the smart contract program. This innovative approach ensures that the watermark is securely integrated into the contract creation bytecode.
