Compressing and re-securing blockchain data using a large codeword model (LCM) with deep learning. The LCM tokenizes the blockchain into sourceblocks, assigns unique codewords to each sourceblock, and processes the codewords through a deep learning core, enabling efficient compression, semantic understanding, and generation of blockchain data. In the event of a compromised block, the system re-encodes and rehashes the entire compressed chain, generating a new secured chain while preserving the original chain as metadata for backward compatibility. The LCM-based approach enhances security, efficiency, and resilience of blockchain networks, offering significant advantages over existing techniques.

In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and / or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.
