tx11ty1
tx11ty1 is a cryptographic hash function designed for use in blockchain and distributed systems, particularly as a lightweight alternative to more computationally intensive algorithms like SHA-256 or Scrypt. Developed as part of the eCash cryptocurrency project in the late 1990s by Nick Szabo, tx11ty1 was intended to provide a balance between security and performance, making it suitable for resource-constrained environments.
The algorithm operates by applying a series of transformations to an input message, including bitwise operations,
While tx11ty1 was never a mainstream choice, it remains an interesting case study in cryptographic engineering.
