 Due to the exponential nature of coordinate growth in iCGR, encoding long sequences (e.g., full genomes) directly is computationally infeasible. To mitigate this, `chaoscoder` implements a block-based iCGR approach. Sequences are partitioned into fixed-size, optionally overlapping segments (e.g., 50–100 nt), each of which is independently encoded using the iCGR algorithm (Figure 1).

 The result is a scalable encoding strategy that maintains the reversibility and precision of iCGR while enabling genome-scale processing.
